Great video! I've been watching a lot of various quadcopter "how-to videos" on CZcams, and from start to finish...this might be the finest I've seen so far. Sharp focus, good audio with well paced narration. My point being your video was easy to follow, well explained, without being boring or excessive at any time. I'd like to see more of this type from you! You're great at it, and the r/c community could benefit. Thanks again!
Thanks for the optimistic feedback! Sounds like you came away with info you can use and didn't get to bored in the process. That's exactly what I try to bring to the table. Definitely much more to come.
Dustin Dunnill Yeah, just got my CX-20 in the mail yesterday...so I'm soaking up all the information that I can get! I learned a lot from your video, the only thing that would help more, is if you put some links to some of the new equipment. Atleast I'd know what to call it, where I could start my price shopping search.
No problem. I'll put some links up soon for the stuff I used.
Ramtough1 Links up :)
Dustin Dunnill Fantastic job Dustin! I can't thank you enough!
Thanks for the informative and thorough video Dustin. I just ordered a CX-20 because it's a great, inexpensive platform with tons of user knowledge available. You've given me a bunch of ideas to try out once I get comfortable flying the machine. Thanks again.
Right on Rich! Have fun!
Thank Dustin for taking the time to make this video. It is very helpful.
You bet Don.
Dustin that was a best overview of mods I have seen. Just getting into CX20 bought one used. Look forward to learning more.
+Doug Leppard thanks Doug. Be sure to visit the cx20 forum on www.rcgroups.com huge amount of mod info :)
I see you are working late in HI. I am a member of RC Groups and before your video looked at the forum on the CX20, it has 67k+ posts. But your video and links were the best and a map for the direction I want to go. I had a small quad with FPV and really enjoyed it ready to go to the next level. BTW investing the $5 for your work is the cheapest investment ever to learn.
Looking at this one to mod it up. Prices are great right now
Love the capability for telemetry and OSD. Great video
Thanks for the video. Helped me make the decision to buy one of these. Got it this weekend. Excited for the wind to die down to fly!
+Cormac McG 👍😁
Awesome setup. My CX20 should be getting delivered today!
Thanks. Right on fly safe and have fun! If this is your first quad, take it easy and do all calibrations before you fly.
I ran through all the calibrations and flew two batteries through it and it flew great! Unfortunately it started to act funny in position hold mode and flying uncontrollably, I landed it and switched to manual mode and it flew great until the prop fell off and it crashed... Lesson learned, I believe it was acting funny due to the vibration from the loose prop. I calibrated both times, should you calibrate every time you fly?
this just proves what I have always said.
cheerson makes a solid product, and with little modifications such as these they can easily compete with much more expensive products on the market.
can you imagine these kind of features, from the factory, for under $400-$500?
I think cheerson could pull it off and finally make legitimate FPV quads available at a super affordable price point
Mine is in the mail any time Gearbest is slow but they have always came through for me.The first thing to do is pull it apart and check the soldering then start ordering parts lol thanks I have a lot of fun just modifying stuff. Thanks for your time and trouble my friend. Keep it in the air.
+ziggyzbeak thanks Ziggy, have fun.
NICE!!! I just ordered mine from banggood for 170ish. I'll learn it then get the mod bug and come back here to do what you did. I do have extra phones and a gopro. Thanks for this vid!
I have to comment this one! Very good explanations, I also have an cx-20 and sony action cam AS-15 and you help me a lot! I have only just about 1h of flight time with my cx20 because I bought a Eachine H8 3D to train my skills first!
Cheers my friend!
And thanks for links in description!
+KTM Laranjinha (Linhos) Thanks. Happy flying :)
You Americans are fantastic. You take your hobby to the next level (: thank you for the wonderful video sir
Very well done video. your North Shore video was awesome. I will attempt the mods you have made with my cx-20.
Thanks Greg. Good luck with the mods.
Dustin Dunnill Hello Dustin, how many layers of the zeal tape did you use? Would it be possible for you to provide more detail on the Sony output cable you built? Thanks.
Hey Greg, just one layer. I put a small square of it on all 4 corners of flight controller. I also mounted the receiver on zeal but not sure if that was necessary. The sheet you get goes a long way.
Hi Romeo,
Practice, practice and practice 100 times more than you think is necessary on a toy quad while your waiting so you don't have an expensive crash with cx20 and your mods :).
Zeal squares on 4 corners of flight controller is all that's needed. More will waste it and add weight to cx20.
Yes. Great idea using zeal to combat video jello for camera, but you may want to have a safety tether since camera can move around at angle much more than flight controller.
+Terry Bennett The open source versions (both the CX 20 and Quanum Nova are "Open Source") allow you to use an amazing software package called Arducopter/Mission Planner. With that software package you can do a number of things, such as update the firmware, tune the flight characteristics, download and analyze flight logs, trouble-shoot potential issues, and the coolest thing is that you can create a flight plan that you upload to your quadcopter, that it will perform autonomously.
Well said Dan.
+Dustin Dunnill Thanks Dustin! Hey, can you comment on my earlier question when you get a chance?
great vid love your mods i have the cx20 here and iam looking to do all the mods you've done thanks for sharing
+billy somerville Good luck with the mods. You'll find all the parts I used down in the vid description.
I noticed that you do most if not all your mods with the Open Source version of the CX-20. I have seen other CX-20 advertised with no mention of Open Source. Is there really a difference? and What is open source about it?
This is going to be perfect for mapping!
Been waiting for this vid! Thanks for posting. Did you have to tune the walkera gimbal using mission planner or GUI?
Your welcome Chris. I tried some tuning but always seemed that default setting were best for my setup.
You can only tune in mission planner if you run your pitch or roll (or both) signal wires through the flight controller as I've done (check rcgroups cx20 forum in description on how).
Hi Dustin, thanks for the video. I had a question regarding your telemetry coaxial pigtail cables. have you had issues with large amounts of loss whilst running the the pigtails? I'm experiencing around 12db of extra loss when running the pigtails on a 433mhz telemetry radio using 4inch RG316 coaxial pigtail.
Great info vid Dustin! I'm on the fence between this one and the 3D X8. I was leaning toward X8 as it already comes with a lot of things I want in my 1st big boy camera quad, plus I saw your review of that thing flying with no landing or cam and looked a bit sporty as well. Only thing is I hear it's a bit cheaply made. Since it for around the same money what are your thoughts between these two. I will be using it for cam stuff mainly so WYT?
Thanks for the informative video. Looks like you have quite the setup on this drone
Thanks Bill. Very capable with this setup and super economical compared to the main brands.
+Dustin Dunnill Hi, I would like to know how u blocked new landing gears down the drone, cos on mine it seems they are not stable with original CX20 screw landing gear.
Thank u very much
Wow! best informative video I've seen on this subject. Love how you improvised your own unique system. definitely using a lot of this info for my first setup. Thanks so much for this. Light Pros.
Cool. Glad it helps.
Helpful video. I have a few of Quanum nova versions. I will convert one for long range.
Thanks. Glad it helped you out.
Good job Dustin, can you give more details on how you connect your SONY HDR (pinout, etc...). Where can I get the cable from the easier cap to the android phone, and is the SONY gimbal adpater available somewhere?
Thanks
Great video,very thorough....quick question,,,is that the minimOSD? I tried using it on another quad and could never get it to work right..ended up bricking both of them.
Yes it is. I just put a link up for the one I got.
Hi Dustin, as usual awesome video , I already used one of your videos and made my Telemetry connection to my cheerson cx20 and project went well, now I would like to add my Minim OSD to the cheerson cx 20. I watched some videos and updated and setup the OSD hardware so I'm having problems to connect the OSD to Cheerson apm. Please do you have finally any video provided for OSD connection ? please direct me to. Best regards
What an in depth review of what is possible. Well beyond most people's comprehension though. My Nova in stock form is a dog! I'd be happy if it just flew stable never-lone in GPS mode!
+endwood have you tried mission planner? recalibrating the compass, things like that? you can also try a set of 9450 props (genuine dji are good, gemfan blades are ok for cheapies)
may be a silly question but can you give it way points seeing as it has GPS? Ive been flying planes and cheap drones with no experience of gps so dont know if having gps just gives you co-ords or also lets u set way points. great vid though.
exactly what i want to do with a syma drone and my sony action cam and that exact gimbal thanks for posting your drone man
+KcKreicar Cool. Your welcome
Hi Dustin, Quick question about adjusting mission planner spec.s for the heavier battery load? Have you updated the hover throttle & RTH parameters to compensate for the additional weight? If so can you suggest some starting figures for testing???
+Mark Webb Yes, you will have to raise your throttle MID parameter in mission planner to compensate for more weight you add. I think mine was around 600 fully loaded. If you hover for a few minutes then connect to MP, there is another value where it thinks the throttle mid should be set at. I forget the name but it will give you a good starting point.
Great work Dustin I you had any problems with flyaways because it seems to be to common with the CX-20.
Thanks. Flyaways happen to all GPS copters. Even DJI phantoms have around a 30% flyaway rate. Mainly due to pilot error not waiting for a good GPS lock. Other reasons could be interference, component failure/glitch. I've never had a single one myself.
This is so awesome! Thank you for posting. For the props I use 3DR 10-inch props and it seems pretty stable and has tons of lift. Still I'm curious to try the DJI 9450 as most have used it. lol
Thanks Victor. Hope it helped you. I'm assuming you had to shorten the tips of the 3dr 10" props to keep them from hitting each other and re balance?
It did. Thank you Dustin. About the props, I didn't have to shorten the tips. They worked alright with good amount of space. The only adjustments I did was widening the hole to fit the motor shaft.
Sounds like motors are out of sync. Their are a few videos out on CZcams for how to calibrate.
Hey Dustin, i have a question regarding the video TX and Rx. i know this may be a typical question but can't really find a solid answer. Anyhow, i continue to hear that in the US it's not fully legal to operate the video TX unless the device is certified? any comments? or PM please.
Am thinking about buying of these cx20 but after looking at some much video online, I notice a lot of crash is it known to just drop out the sky like how a lot people online say?
Great Video Dustin Dunnill. I've a small question. Is that possible to mod this for Auto fly mode (Flight planner) same as Parrot Bebop has. What I meant can we give flight plan before we fly and let let the drone fly in according to that plan....Thanks
+Janusha Premarathne Yes, it can do it out of the box but needs programming for route through PC. Add a set of the 3dr telemetry radios and the 3dr tower app on phone or tablet/PC and you can have real-time auto missions like bebop or phantom.
Thank you very much for this video! Very interesting upgrades! I've got some questions... may be my english not so good, but i don't understand
what for you using 7th channel?
Battery stiked to transmiter used to supply all transmiter or only for booster? Where is your FPV reciever?
Witch configuration, you think is better when compass in dome, and GPS in dome? Or vice versa?
GPS can be isolated by usual foil?
What do you think about replace original shell for F450? I think it will be better in terms on wind resistance because of design, and it will be more stable because of distance between motors, and this frame allow with no problems use 10" props, but i afraid of low motor power.Whitch motors a default on CX-20 (mean KV)?
Watched some of your videos, it is really cool, but i'am disapointed with image quality, and awful vibration. Actually i'am not satisfied with quality of airshooting by GoPro 4, may be i want too much for action camera... but i'am looking for a really good camera for airshooting.
What do you think about props? Witch one are better? Have you think about upgrade to carbon props?
I really like self loking props, but i dont know how to balance them( Do you ballance your props?
May be using a bit heavyer gimball will be better stabilized?
Sorry for to many questions, i've found you experience very exciting )
Thank you
Hi, wow that's a lot to absorb. I'll try and answer what I can:
1. I use The 7th channel in flight controller set to use autotune as mentioned in video. Please visit the rcgroups link in description for info on how.
2. TX still uses AA batteries and lipo is only powering booster. You could wire lipo to power both if you wanted but I did not.
3.FPV receiver is the RC832 (not shown in video) which attaches to end of easycap. Check CZcams for basic how to setup FPV.
4.I have only done compass in puck and GPS in body dome as shown in video. Visit rcgroups to see what others have to say about other way around.
5. The frame is also talked about extensively in rcgroups link. Supposedly more stable but it is now like a car without a body. If that matters to you. I like closed body.
6. Yes some of my earlier videos have bad vibrations. I am still tuning them out. Resolution just depends on camera. I'm using a
+Dustin Dunnill I bought this power module and configured it for the CX-20 FC but it doesn't read the real current voltage. I measured the voltage with a multimeter and set this current in the MissionPlanner but after a long flight the current voltage won't change. It doesn't seems to work for me. And yes I had switched the ports for the FC from the power module on the connector for the FC.
Hi, can I ask please, you moved your aux2 dial to the side for your gimball, I have put a G"D gimball same as yours on my cx20 connected to aux1 but I find its over sensitive, ie a very small movement is required for a lot of tilt on the camera, is there a way of reducing the gain at all?
Good question Steve. I have the same "sensitivity" issue. It helps if you pitch the camera all the way up and down a few times to it's full extent while it's acquiring GPS. Don't ask me why but it seems to help a little.
Very nice build I was thinking of doing the same for FPV on mine but I've decided to try build a qav250 just waiting for it to show up! I find the cheerson a tad bit slow but it is a great filming quad👍
+Camshaft Shaft Thanks. QAV 250 race quad? Definitely a different class of drone but fun and fast for racing. Have fun with your build :)
Hey. I just put a gopro hero 4 on my Walkera G2D gimbal, and the video is a little shaky. I'm not exactly sure why. It has a video out cable (silicone like yours) going to the xmitter. Could that length of cable vibrate in the wind and shake the camera? Did you have this problem? The camera is mounted to the gimbal using a velcro strap which seems tight enough. Thanks.
Hi. I have a Quattro twister which is same as cx 20 for uk market. However here is a question. Did u replace the GPs for a better one ? And put osd and video transmitter all inside and drilled a hole for the aerial for the video transmitter below ?
Stock GPS. Yes all OSD and telemetry inside as shown in video....
hi what is the differencw with open source? are they all thesame with the standard cx20? thanks
Does the 5100 battery fit right out of the box in the cx20 or you have to use spacers for the board?
Hi Dustin, I was wondering what your overall cost for the FPV system was in order to get your CX - 20 to go as far as 3 miles? I would like to purchase the Cx - 20 and would also like to get at least 1 mile. But If I have to invest too much I may as well get the phantam 3 advanced for $800 which is on sale currently. Please give me your input, thanks
When you added your DJI 9443 size props did you have to change any settings on the apm? I added 9443 props and mine is extremely unstable and wobbly. Did yours do the same?
Hi Dylan, I have the 9450 authentic dji props. I first tried carbon fiber cheapies and they made it very unstable and I crashed but vibrations were the culprit. Make sure your props are balanced, try the zeal gel under flight controller, make sure center of gravity is good and it should be much better. Ultimately wire it up for autotune capability (instructions in rcgroups link in description of this video) and it should fly butter smooth.
Hey Dustin, I've watched all your cx20 drone videos so many times! Love them all I'm just wondering is there a step by step guide for installing OSD. I'm looking to add it to my look+ camera.. I would just use the telemetry port on my drone..
Thanks again keep up the great work! Love all the mods you have done
+Dean Petersen Thanks Dean, I was able to connect mine using some tutorial vids from youtube for the minimosd and also learning from advice at the rcgroups.com cx20 forum. lots of posts and pictures their from active users which should help you get it done. Sorry I cant be of more help at the moment but its been ages since ive touch my poor cx20. need to get back to her. Good luck man.
+Dustin Dunnill I'd love a video of a how to install osd on a CX-20 as well! Hope you can make one
Hi. Very good quad! Did you powered the FPV receiver by an external batery?
Vrx Receiver? Yes, you have to. That's the part that's on the ground with you. The VTX is on the quad. I have everything using main quad battery.
Hi! thx for the video ... is the plastic version of this gimbal lighter than the metal one ? and is it have the same performance ?
I think it is lighter. Maybe Google for specs on both. All I have is plastic version. Don't know on performance because I don't have both.
Hey, great video. Used quite a few of these mods :) Could you let me know which android app you use for the telemetry?
The 150mm high legs are great, and I just got the USB telemetry. Installing It'll be tricky since I've updated the firmware and will need to upload the hex file.
Thanks for a great video!
Thanks Jonathan. 3dr tower app. You can find the firmware for 3.2.0 on rcgroups modified for telemetry to work :)
+Dustin Dunnill Thanks!
hi do you recomend this one over the Hubsan X4 H502S ? i need good range thanks
or the 380
Thanks for this video! quick question though, I currently use the 8" DJI phantom 1 self tightening props on mine, and I was wondering if I upgrade to 9" or even 10", would I have to re-tune the flight controller? I thought I heard it mentioned in the video but I cant find that bit now.
Your welcome. You'll want to first test fly with the new props in soft grass wide open area and don't go higher than 10-15 feet to see how it flies. Try all the modes with new props. If it seems out of whack then yes. I would look into hooking up channel 6 or 7 from rx to flight controller for auto tune capabilities. For more on it check the rcgroups forum link in video description. Also this will tell you what the flight controller software is all about
copter.ardupilot.com/
Hi ! Thank you for help us to upgrade the quanum !
I'm french with poor english and I would like to know what are the best propellers for batterie life (and a long flight time)? The dji boosted or the gemfan ? Thanks
+clement brun DJI Pahntom 3 props, not sure on the best battery but I am sure there are some newer ones that fit and last longer by now.
How long did it take for you to get your CX-20 from Gearbest? Coincidentally, I ordered one from them just before discovering your videos....they seem kind of slow...I'm wondering if I should have ordered from Banggood instead?
I think it was 3 weeks. I've order some things from banggood and took over a month.
do you think that i can like do a modification in the gimbal to put a tomtom bandit?
Where do you find that sun guard thing for the phone? Thanks for a great video, I got this quad yesterday on my birthday ;-)
It's just a generic dji phone sunshade. Check the links in video description
Will the clips on the transmitter for your phone hold an 8inch tablet?
Thank you, an yeah I meant to say tablet. So if I may what are the things off you list that I should get. I saw a FPV system on that site monitor and all for $127.00
Where did you get your easycap with the UTV007 chip? I ordered one from ebay but it doesnt seem to work. I has a green board inside and has SM2021.
Here's a thread I started on the easycap with plenty of good info on what others are getting from different vendors: www.rcgroups.com/forums/showthread.php?t=2416458
Seems like a lottery but me and others have had success from Gearbest.com with the 007 chip.
Howdy, Dustin - When I was ill I watched this video and, over time, purchased all the parts I could afford to mod a Quanum Nova and TX accordingly. It's Easter '17, and I'm finally starting. It would be cool to add telemetry. (I'm a newbie.) So, I looked at the forums link below and didn't know where to go. Maybe a telemetry mod might be a bit much... I don't know much about soldering, and I don't have a spare Android... Even figuring out how to apply the Kyosho tape is... again, newbie. Anyhow, might you please be so kind as to help me with more specifics regarding forum links to mod this quad? Maybe a quick help on how to regulate the 2W TX booster including "regulator" product and Lipo wire/down product descriptions. Great work! Thank you!
Dustin, I have a cx20 (big shark) and added a nice little OSD module and it works great. Just ordered an open source version cx20 and want to add the OSD capability. Do I need both the OSD board and a Telemetry board? I understand it is on 900gHz so it will require a separate transmitter. I am using 5.8gHz on my OSD now. Just want the same capability because I use a tripod mounted FPV ground station and want to see overlay. Thanks for your help....Happy Thanksgiving!
If you only want OSD on your video then just OSD is needed. Telemetry qwould be for if you want to wirelessly connect to change parameters or use mission planner software for automation, voice alerts, etc. Happy thanksgiving :)
Thanks Dustin.. hope you had a great Thanksgiving! I ordered the 3DR Radio
set, and the Mini OSD System w/GPS Module. Hope that will cover everything!
Great review. Four questions. One- For the FPV on the phones, can it work with an iPhone? Two- The drone gets 6 Mile range, but is it the same for FPV? Three- What is the purpose of the Telemetry mod? Four- Can this mod be done on any drone?
hi dustin ive just ordered to zeal tape for the fc and trying to figure out this autotune wiring dont suppose you could point me in the right direction ,also do you need to remove the wires after wards or can you still use the aux knobs to control the gimbal cheers tim
Hi Tim, basically your just disconnecting one wire going down to gimbal so it goes from a trx channel directly into the FC. Pictures are necessary for explanation and there are a bunch with instructions in CX-20 rcgroups forum linked in description. Just search for " autotune " and browse what comes up. Everything is there you need.
Oh..forgot. Yes you can leave old wires after gimbal side disconnect. I would cut, shrink wrap or tape end though.
Cheers Dustin I'll hit the rcgroups again see if I can grasp it
nice vid ?did you have to put a bec on the battery side .of the cheerson .ive bought 1 and like to know if it safe to put a 5400mah in it. will it efect . the esc,s
+richy todd No BEC was necessary on the craft. I did put one in the controller when I installed the booster thought... another video I did.

How do I install the telemetry? do I need to do any soldering in the drone? From what I have read, you can plug it into the part of the board in the drone labeled UART but do I have to do anything else?
Sounds like you got it right. The new models have the UART plug. You may just have to swap the TX/RX wires on your telemetry radio. Then it should work with your radio set. You can also change telemetry settings in the mission planner software if needed. Check out the CX-20 forums on rcgroups.com
hey Dustin, so I was able to fix my cx20 and fly it a bit and the inevitable happened again and although I fixed the quad the gps light blinks for a few seconds and shuts off. I tried searching rcgroups but not much info. any ideas of what it could possibly be. any input would be appreciated. thanks man
I would... Wipe and re install Arducopter firmware first. If that doesn't do it check connections and cables. Lastly get a new GPS.
Hey Dustin! I just bought a hobby king quanum nova three weeks ago, I hooked it up to mission planner and it got disconnected accidentally the wire came out! now is just beeping, won't load and the beeping won't stop... what can I do to get my nova up and running again, any advice would be greatly appreciated!
Bummer, can you re connect to MP?
Thanks for the informative video. Just to clarify, where to connect the 5-pin of the battery power module? Thank you.
Hey Renevic,
Any cx20 you purchase now should have a port on flight controller to just plug into. My older model had to solder to the main chip very carefully. Details are in the rcgroups forum.
Do you have to calibrate the Nova / CX-20 every time you fly it or does it set the RTL where you turn it on to fly? I set my Nova up with the mission planner at my home but do not want to try the RTL if I need to recalibrate it at each place I fly. Thanks for any help
It will set it's home point when you arm. Just make sure you have good satellites. A good way to test is by trying to arm in loiter mode then take off in manual mode. It will not arm in loiter unless GPS lock is decent. Once armed in loiter flip back to manual, take off and fly how you like. It should have a decent accurate RTL if done this way.
+Dustin Dunnill Thanks for the help and fast reply
Hi Dustin, Like you I have a walkera G-2d gimbal connected to my CX20 (open Source)
I have a problem with the ultra sensitivity of the Aux1 and Aux2 on the pitch and roll. I have been looking for a fix but have been unsuccessful. Did you have the same problem with yours? if so did you get it sorted?
Thanks
+Mel Mann Hi Mel, Mine is also sensitive. Seems like when you boot up, if you roll all the way up and down once or twice it helps a little. Otherwise I've tried everything and it is still rather sensitive needing good finger control.
+Dustin Dunnill Thanks for the reply. can't be sure if it is a problem with the gimbal or the controller. 😕
How's it going Dustin..my cx20 is going from one problem to the next. got the gps working. had to replace gps. also replaced the power board due to a broken capacitor now my motors won't unlike just get a quick blinking red light. searched all over but trying to get a second opinion. thanks
+Leo Gates Bummer Leo. Have you crashed?
Damage from last crash a few months ago but actually got it working. Had to reboot firmware. Now works fine. Stoked to fly again. Gonna check out your vids for a backup flyer just in case. Or might try the walkera 250. Any good??
Hey there I'm getting into this and got the cx-20 I have full fpv. And want to add the osd module How do you wire everything up. Anyway we can PM or anything to help me out with wiring.
+Dillon Dolohy Hey Dillon. The wiring has been covered extensively lin Rcgroups. I think I linked it in video description? If not, go to rcgroups.com and look for the cx20 most popular thread. Many great people there that can help and it has all been done and posted with instructions and pics.
good video,
seems you went through a lot to get it to where you want it,,
I know you said this aircraft was reasonably priced, but for a little more you could have avoided a lot of work, by just purchasing the 3DR iRIS PLUS,, Its my fifth multirotor, and most def the most capable, in EVERY respect, including the price , before buying a gimbal and fpv gear etc, you can get a bare bones set up new for under 600 bucks, with telemetry radio and auto flight capabilities its a great deal, not to mention the companies outstanding customer service, those guys are terrific.
its a great open platform copter, and does mostly everything you went over in this vid,
including telemetry , autonomous flights , limited only to the battery life, (providing you shut down your geo fence, through the pixhawk setup which is very very user friendly using APM planner online,, )and your right about that battery , I have three of them and their great, the only thing I may have to improve, and I have not checked this yet, is the range of my fpv, set up,which I just ordered online and have not received yet, but will most certainly experiment with . I currently use three different cams, a go pro knock off, which is great, however, if your streaming you cant record,,, which is strange,
I also have a mobius which is outstanding, and finally I have a Yuneec CGO1 cam which auto transmits without a transmitter , it has internal transmitter, , however the quality of the vid is not as good as the mobius but very acceptable,,
your vid was very informative, and well made, good job,
and good flying
Thanks Elmo. Bare bones with no FPV for $600? This one cost me around that price all together so it is a deal but you definitely won't get customer service and the quality will not be par with 3dr. But it's a good GPS quad for cheap to start and learn on if you have some tinker ability.
yes, its outstanding,, Im pretty good with these types of things, but its a leaning process regarding fpv, programming etc,,and this is a good platform for that, Im in the middle of trying to figure out how I can add a basic servo for a drop mechanism with the existing radio, and getting nowhere fast,,lol
thanks
Cool. I've been meaning to add a micro drop servo on mine to get that fishing line way the heck out in the ocean :)
If I'm correct, the "Telemetry Radio Set" is only needed when I want to show telemetry on a seperate screen, right? When I run an OSD telemetry setup, this is not needed?
+GermanCube you really only need the telemetry radios if your going to use the 3dr tower telemetry application on PC, phone etc. Otherwise you can just connect your OSD directly to the UART telemetry port, splice your camera in and your set to have it on your screen :)
+Dustin Dunnill So the CX20 comes with telemetry on board?
Haha hello MrD great video from the past I never saw until now .hope thing ok Quading.
Hi, I got the same battery you recommended, can I use the oem balance charger that came with the cx20 to charge the 3DR 5100 battery? thanks
Cool. Nah, stock charger will kill batteries in no time. get a decent smart charger if you want them to last. A $30 or sky RC B6 or similar charger should be fine.
Sorry for all the questions but how did you know that the EZCAP you were buying had the correct chip set?
I bought two supposedly different models
and nether one worked on my Android S5.
Christopher Jacques I did not know and got lucky mine had the 007 chip which seems to be most compatible with the easycap viewer app. Sorry yours aren't working. Maybe try ebay, I hear there is a seller guaranteeing the 007 models.
Dustin Dunnill OK cool. I'll check it out tonight.
Thanks for your reply.
trying to figure out how to power up the transmitter are there any links to doing this?
Hello, I recently got the Cheerson CX-20 and the Self-Locking propellers from the DJI Phantom to go on it. I did some research on the propellers and saw that they are usable on the Cheerson. However, when I put them on, it seems that some stick out more than the others even though I tightened it the most it can go. There is pictures of it that I linked at the bottom of this post. Also, my biggest problem is that when ever I hit the RTH button, it starts to come back to me and then all of a sudden looses power or slows down and crashes to the ground. This has happened twice and the second time it did a good amount of damage. I'm not sure if it's defective or I accidentally hit the throttle (even though I thought that when in RTH mode, using the throttles have no use whether you put them up or down or whatever). Does anyone have an answer to this? I have gone through 2 sets of propellers so far (The default ones, which broke from the first RTH fail, and the Self-Locking DJI Phantom ones, which just broke from the second RTH fail)? I am almost ready to just replace it for another one.

Thanks.
I looked at your pics and something is not right. I have a few questions to ask so I can better help:
Are they genuine dji props?
Are the mount bolts the props screw onto all the same length? (Measure).
One of my props is a little harder to screw on than all the rest. Try and apply more pressure to screw on the prop that is not going on. They should all be down very close to motor.
Your prop issue is most likely why you crashed.
Important: since you had some crashes open the body and check for anything loose ie: compass, GPS etc.
Visit the forum I have linked in description.
Dustin Dunnill I asked on another forum whether or not the props would work and they said yes (I got these: www.ebay.com/itm/4-Pairs-9-9443-Self-Locking-Propeller-Prop-CW-CCW-For-DJI-E-series-E300-Motors-/291229589483?bvflow=0&rd=1&rmvSB=true)
I tried putting them on the drone that I had already crashed with the default props so that may be the issue. I ordered another CX-20 so I will wait until it gets here so I can see if the props fit on it. If it still does not fit, do you recommend I get new props? If so, do you know of any self locking/tightening props that would fit without any trouble?
Thanks.
P.S. I have asked on rcgroups before but didn't get an answer so another site recommended that I ask you.
Good info man! What do you use to power the telemetry receiver? Does your phone's USB provide enough power for it?
Thanks, hope it helps. Yes the phone/tablet/ PC you hook it up to will power it.
Dustin Dunnill cool. Another question. If i install minimosd, is it okay not to use the telemetry receiver? I think id rather just have my nexus 7 display both video and flight info. Thanks a bunch!
Yes, you don't need telemetry radio set to use OSD. You just have to tap into UART port and put OSD in between it and VTX.
Dustin Dunnill gotcha! Thanks!
Dustin, what do you use to power the RC832 FPV receiver? Thanks
Hi Mario, 950mah 7.2v lipo
Sir I bought a g2d gimbal and every thing is working fine execpt with slight movement of aux knob of cx 20 remote the gimbal turns fully down or up.please help sir.
Hi Dustin, My oh my you have thought this all out, nice job. Would like to see some flight videos. I have the Cheerson open source CX20 also. The dome tower, I am assuming that it is housing the compass for the GPS functions. I had a little mishap and now the dome has a slight tilt, will this hurt anything. Thanks for sharing this video.
Yes, got it dialed in pretty good now. As long as compass is pointing forward inline with front of quad the tilt shouldn't matter.
Check out all the videos of it at bottom of the description or in my channel. I have a bunch and more to come.
Ok, great I will look. Thanks for the info on the compass.
I have a Sony Action Cam X1000V, so i am wondering if I it can output analog video signal while is recording.
Is this an automatic process or I need to configure something?
Thanks
Sorry for my English
It's automatic on my as20. I honestly don't know if that model will output though.
Hi Dustin, I was looking at the extension cable link that you have for the telemetry. it is a SMA male to male. now i dont have my telemetry kit yet, but shouldn't it be a female - male extension? (thats if using stock antenna). from what i know if using a circular antenna i would need an adapter RP-SMA to SMA.
+Mike Vlascov it's hard to get ahold of the exact cables sometimes and an adapter only weighs a couple grams and are cheap. I'm sorry but I forgot the connector gender at the moment. I'd get a bag of adapters and you'll have some for future craft also.
+Dustin Dunnill another question. could you please point me in the right direction regarding the power module. as the cx-20 does not have a PM plug. Thanks
You did well with propellers 1047? I bought the 1050 and I have not tried it yet, I have multistar 2216 engines and 20A esc, you think with ogirinales drives have problems with these propellers? how long battery gives you the propellers 10 "and how battery?
I never got the adapters to put the 1047 on stock motors before my big crash (see video). I have to move to new shell and maybe try.
I think stock motors should be able to handle the 1050..but best to exhaust a full battery in a hover test and check motor temps immediately afterwards. If they are too hot to hold comfortably then the motors cannot handle. :)
I have Multistar 2216 engines led 920kv, have told me that the 1050 propeller can come to touch each other, you have had such problems with the 1047? if not fly are 1050 or not ... I'm scared that the pro
Thanks for the video, is it possible to show hot to install the telemetry? Thanks!
Gocht Guerrero Hey, I'm going to move the guts to a new shell and I'll try to make a video for telemetry. Stay tuned :)
This is an awesome video. Thank you for sharing this info. I will be following your model to the T. I am currently waiting for the parts to arrive. I have a couple questions for you though.. I bought a GoPro Hero4 Session for FPV and recording. I was unaware that it does not have an anolog video out on this particular camera. After looking at info from the GoPro site, I found that it DOES have a live feed but, only through micro hdmi port in HD format. (1080p/60) Could I just simply use a converter (www.hobby-wing.com/arris-fpv-hdmi-to-av-converter.html) before plugging into the FPV transmitter? I would think this would solve the issue. Please let me know your thoughts?
Thanks. The converter is what I would do bit I've never attempted. You can find some slim ones on eBay
Say their was an fpv screen onboard the transmitter. Would the parabolic dish interfere with video playback?
Yes, if the dish is blocking FPV antenna
Hey sorry I have another question.
Can any current sensor be used with the minimosd?
Yes, you have to install power module and you can have voltage and current on OSD. Link in description.
Hi Can you send me the link for the how to on setting up the fpv for phone view please?
Hi just order a new CX-20 how did you set up your F/C with telemetry? Great video's.
+Soldier53flyer rcgroups.com cx20 forum has all the info
Thank you,
Hi I'm interested in buy a cheerson cx-20 have been doing some research on it, my big thing is I would love to use my table to monitor the video being that I shoot a lot of music videos as well as weddings. so what would I need to get that to work. I'm thinking may gopro with a gimbal for steady video.
Do you mean tablet? You'll have to have an android tablet , FPV setup on the Drone and have an FPV receiver and an easycap you plug into your tablet which converts video to show on your tablet along with easycap viewer app.
I can't seem to find the taller f450/550 legs, I ordered some from eBay and just like you they came as the shorter ones. it says 150mm height on every eBay add so idk where to find the taller ones.
That's too bad. I got mine from my local hobby shop which were long. But also ordered spares which were short. Maybe look for "long" in description.
sur
I am using original 9540 dji prop.the motors are getting hot (I can hold them with hand after flight).Is there abything to worry about it?
I don't think so. One or two of mine get a little hot after flight bit no issues. If you can hold them without hurting at all they should be fine.
Hi Dustin, thanks a lot for this video ! I just learn a lot about Mod capable.
Have u the interference between the Wifi of the Camera and the transmitter? because there are interference between and i cant fly with my wifi camera ON.
What is the solution?
Thanks,
Hi Nate, Don't use WiFi on camera when flying. The controller and camera WiFi are both 2.4ghz and you will crash. Use a 5.8ghz FPV system with no problems.
Hi again, thanks for the advice.
Can u sen me a link for get the best FPV system ( and cheap ). ?
Nate Grillz Check video description for parts I used.
I am purchasing a Quanum Nova and I would like to modify it for FPV etc. Can you do a step by step from the beginning and if those mods will work with the Quanum Nova?
I'm doing a shell swap and will try and make a step by step videobwhilebin the process. Yes, the Mods should work on the Nova (same Open source quad).
I'm split on what to buy, CX20 or Flying 3D X8? If I want to go out far, which would you recommend? Same set up as in the video.
X380 I think. Check my range mods and flights with it. It's easier to fly also.
Hi, The 2 watt booster, your running it at 6volts,,have you run it at higher voltage? do you think it would work at 6.6v? I got one and I have a spare 6.6v life battery.
Have not tested higher than 6v. The literature actually states it is made for 5v so I'm not sure. My 6v may be pushing it a little.
+Dustin Dunnill Thanks for getting back to me. So how many hours would you say approx. have you run it on 6v? also is there a way of testing if it is working or not? reason I ask is I have used mine today, without plugging it in to the battery, so I am just using the power from the controller straight through it. I will power it on 6.6v at some stage and see how long it lasts before failing,,,if it does that is.
BTW, I have enjoyed your videos and the mods, and the great views!!! thx.
Thanks Ray. I would estimate I've had 6v power to booster for maybe 5 hours total in 30min increments.
hello friend wanted to know if the big shark version can be connected telemetry ?
I would greatly appreciate your response
+daniel catrihual urrutia I don't think the older models could but the newer ones may be different. sorry, i'm not sure. There is a CX20 BFS version thread on rcgroups.com maybe you can find your answer there.
