And here is another HOW-TO video, this time of the Matek F765 Wing controller, and to be honest, this one is amongst my top favourites, especially for larger planes! That 8A continuous servo BEC is pretty sweet, and it does have a few more bells and whistles over the F405 Wing, so one might argue it may even be worth the higher price! Running ArduPlane on it has been flawless so far, no issues with the firmware, no issues with the board itself even with 2+ hour test flights and 180+kms covered in that time, so fingers crossed all is well from here on out! I have 3x of these in 3x planes now, one of which is VTOL, and so far I've only good things to say about it, hoping this doesn't change!

Best arduplane set-up video. Thank You
Thanks, appreciate it! :)
Another outstanding Job. As usual, your videos are on point every time.
Haha, thanks! Personally... I find things I could have added... but only find them after the fact! :P Haha, might make a list and do a video on all the stuff that is common for ArduPlane in general! :)
Oooooooo this is just what I need for a friend dipping his toes into long range with a f765 and Arduplane! Thanks Nick!! - Lauren
Thank you! Good luck!
Great video, it's so inspiring to another rc builders. Thank's for sharing. 👍
Thank you! Much appreciated! :)
Great video.
I hope if this video was there before I setup my Plane because you make it a lot easier
Thank you! :) Well, it is here now, so next time around it will be easier!
Excellent work sir 💯👏👏
Thank you! 🙂
I keep coming back to this video. I hope I'm increasing your stats :-)
Every little helps! Thanks mate! 👍
Just what I needed! Many thanks.
Great! :)
Hihi!
I just bought one, and I'm putting it in an Arducopter, so this is highly usable.
Thanks:-)
Cool! Quite unconventional to use this for a copter, but there is no reason it shouldn't work! Most of this would be pretty much the same for it, only difference would be the Servo Output tab, I think!
Thank you, Lifesaver, good video.
Glad it was helpful. :)
We so much like ❤️ it, as you use mission planner , most of them are familiar with mp.
Cool! :)
Excellent video thank you
Thanks mate, glad you like it! :)
superb video! had to slow you down to .75 speed loads of good info
Haha, thanks! :)
Well done another really handy video
Thanks! :)
ive never been able to get iNav working properly (but cound RTH but never navigate) Just ordered the F405wing nano going to give arduplane and try! Wish me luck.
Good luck! :)
You had 666likes, I'm sorry I bumpt it to 667 !
I was strugling to flash Ardupilot on a Kakute F7, you made it super obvious and quick ! Thank you !
Thank you! Glad I could help! :)
Grate video! .. love it
Thank you! :)
That was an incredibly detail video! I can say that I honestly appreciate your hard work... Kind of cumbersome the procedure to swap cameras... I would probably would have set it up to a channel pass through... rather than to go jump all those hoops!! "Finally no disrespect but I would stick to my guns and keep my self flying my large planes on MFD autopilot... that is a system that can almost save me from the worst of my total stupidity!! "Hey I say Almost"
Thank you! I am happy these are useful! You can't put the camera switch to a channel passthru... it is built in the flight controller! With a channel passthru you can setup an external switch! hahahahaha, yes, the MFD is a reliable autopilot, and it does eliminate a lot of the confusion when setting it up... because it doesn't allow you to change much, but it is more expensive than this one... though requires exactly ZERO time in soldering and cable crimping! :) I love mine, that is in the Crosswind Mini!
Thanks for this Video, good work. Can I use this FC also for HexaCopter with ArduPilot.
If so, it would be nice you create a Video about it !!!
Well... would be a problem due to current limits on the power sensor and power distribution board, especially if its a larger one! Also... the board is designed for planes! I guess it could be adapter with a good deal of DIY and compromises to a copter, but I just don't see why, when there are other solutions for that! Also, sadly... I will not be able to facilitate that request... that would be too tedious of a task, and I gave up on copters a long while ago...
I flew my ASW28 on it's maiden with the rudder reversed and landed ok
Right, well the rudder is not as critical as reversing ailerons or elevator, so you got off easy! 😝 Could have been much worse! 🙂
Hi thanks for the upload .. please can you advise the Connection on the Matek 765 board for the dragon link telemetry data ?
Thanks
Regards
Neil F
That is actually pretty well explained on the DragonLink setup website! You just connect Tx and Rx from the telemetry port on the F765 to the ones on the RagonLink receiver, and it should be good!
Extremely well explained and thanks for sharing. On last piece of the puzzle for my lack of skill. How do I map the aircraft servos like aileron/elevator etc that are connected to S3/S4 etc on the F765-WSE board to the my radio mix/radio calibration chanels of 1/2/3/4 ? Thank you.
Thank you! Actually 1/2/3/4 on your radio is literally Servo outputs 1/2/3/4 in Mission Planner Servo output tab! From the drop down menu you just chose what you want to be on that channel.
@@ArxangelRC Thanks for your response. I am using a SBUS receiver with no inputs. In my TX16S Channel 1 is Aileron. In MP Servo1 is Aileron but the physical Aileron Aircraft Servo Cable is attached to S3 on F765 board. Do I change Servo Output in MP to Servo1 disable and Servo3 to Aileron? Apology for confusing question.
@@solarstrategy9967 Well in that case, yes! Sorry for the late reply! Has been a busy few months!
Another awesome video. How has the accuracy of the F765 current monitor and default calibration values been? Any problems?
Actually I was quite pleasantly surprised to find out, at least for the Aggressor, that it showed pretty much on par with what the charger put back in the battery! This means, however, that it is overestimating the current a little bit, because what the charger puts in the battery is not the same as what the battery actually retains, as there is some inefficiency in that as well, but not a lot! So... I wouldn't change it, at least here, on this model, it is good enough! :)
Thank you for step by step manual
You are welcome! :)
Very good explain guy.
Thank you!
do I sill need to use betaflight or inav to flash the firmware for Ardupilot?
or have they incorporated that function to mission planner now?
To be honest... I don't know... I haven't had a new one of these to flash in a long time, but recently did some SpeedyBee 405 Wings, and they did require the iNav configurator to be flashed with the Ardu file...
How do you find mounting your FC directly to the plane body works? On quads some form of vibration dampening or isolation is needed, do you experience any issues like on fixed wing at all?
Can't say that I've had any issues so far, but I do balance motor and prop, separate and together, to minimise vibrations! I also use 3M thick double sided tape to mount the FC... no idea if it helps, but I've never had issues with vibrations on planes after doing the balancing work!
Hi arxangel do you find out any benefits in servo output using left throttle/right throttle?
It looks that you configured it as throttle and not with twin motor function where you might use rud_dt_gain function.
Actually have not tried that left throttle/right throttle setup yet.
When I put my f405 wing in rth it just loiter in that spot when activated it doesn't come back to home position
Does it show RTH on the OSD?
Nice video just wondering where did you jack the dragonlink telemetry wire in the controller
Where the 2nd GPS unit should connect to, just reprogram that in the full param list to output Mavlink.
Thank you!
You are welcome!
Hey i would like more information on your vtx antenna retract. Do you have a video on that? Thanks in advance.
Hey, its pretty simple really - a servo with a Vtx mount printed for it. Nothing fancy! I don't have a video on it.
Nice Job :)
Thanks!
Hi, I’m looking for my first real FC but can’t really decide between the Matek F405 and the Matek F765. They are both the same price. Which one would you pick? :-)
Well the F765 Wing is no longer being manufactured as far as I know! Depends what you need it to do actually! The F405 is a nice and reliable option, but only supports 1 camera input, but it doesn't spill out any interference on 433Mhz!
I'm new to RC building, but searching for a way to use a drone for bird control e.g. the ZOHD and this controller or ? Open for comments and suggestions. Need to fly low over a confined acreage. Thanks so much in advance, Mark
Well... how confined... and which ZOHD are we talking about?
Great and very instructive videos. I would like to ask if ailerons differential can be applied from MissionPlanner or only from radio in case of separated ailerons channels
Hmmmm... interesting question... but I can't be sure about this as I've never really done it. I've only done it via hardware!
Perhaps it might be possible by offsetting the mid point on those channels... I guess... but you will have to try this... just guessing right now!
Thanks for your reply. I already tried with changing pwm values ; i confirm it works , in the sense that a differential between ailerons was possible, but very hard to find end points because with small pwm changes the corresponding aileron deflection was hard to fix. I agree with you about doing it via hardware but my question arised right because i cannot send the differential by radio, and I wondered if it was MissionPlanner that was blocking it in some way. Btw. I'm using an F405 wing, but i don't believe it makes any difference in this sense respect to F765....i hope 🤔
@@CP-zi3eg No, the model of the flight controller makes no difference to this! The autopilot cannot block such a thing from the radio, if you can set it up there, but in any case do it hardware if you can!
Great tutorial as always Angel, I have always built all my planes with arduplane, I just put this FC in a mini talon, the only reason this time I'm going to go with INAV is because of the DJI fpv support. I don't know why arduplane developers still hasn't implemented MSP code into it! Unless you have a solution for that?😊
Thanks! Haha, sadly I don't have a solution, neither do I have the DJI system... too much money... and cannot afford at the moment! I assume they are dealing with quite a lot... and plus... the larger a dev team is... the slower things get done! I mean... I've waited 7 years for the ability to set any mode to any channel... I doubt you will have to wait that long for this... but still is probably not a priority given that it is used by a relatively small group of people, compared to the vast amount of controllers out there, most of which are aimed at industry too!
Hey man!
To enable MSP OSD, set the following parameters (using SERIAL port 2 as the port to attach to the DJI Air unit using both TX and RX lines):
OSD_TYPE = 3
SERIAL2_PROTOCOL = 33
MSP_OPTIONS = 0 (polling mode)
check the documentation: Docs » Items in Master Branch Only » MSP OSD
I use it with arduplane and dji fpv and its usable, OSD config in planner is bad but it's working, all but ladder, horizon and some other minor osd items are not showing. HD OSD is mega!
@@oneistar6661 Nice, didn't know they got it working now!
@@ArxangelRC That was the final push I needed to go with DJI. I expect only improvements from now on.
@@oneistar6661 Yeah, hope so!
Great video as always. I finally got my first f765-wse up in the air. But I have to ask - Did you ever tune the PIDs for FBWA? You didn't mention auto-tune mode in the video. I'm asking because without auto-tuning I had barely any elevator authority. My first flight the plane would only stay horizontal. Roll was perfect though. Was just wondering to be honest
Thanks! I usually don't do manual PIDs, for the most part it is rare for FBWA to be unresponsive with default params but it happens! Run Autotune for 30 swings for pitch only if you wish and see if that changes anything.
@@ArxangelRC that's what I did and it did work! I've watched this video maybe 20 times lol thanks again
@@GiBBO5700 Glad you figured it out! Good luck! :)
even without the user param and dedicated switches , you could trigger RTL without having to turn the radio off. 1st you have to configure throttle fail safe then assign a switch to override the throttle channel to zero which triggers the RTL.
Riiiiiiight... well... sure... but all that additional programming is really annoying! :P
@@ArxangelRC yes true...but I'm paranoid about turning the radio off to trigger RTL! :) ..you are brave ! :)
@@asangag Hahahaha, well... I take it high enough to have time to turn it back on if things go bad... during testing! Once I know it works... I don't even think about it! Always use it as a last resort though!
@@eVroomer I noticed when assigning a switch to a flightmode using user param , the function can only be triggered only when PWM value is over 1800. This means if use a 3 position switch only the 1st or 3rd potion can be used , other 2 are useless ! In INAV you can adjust the trigger thresholds to work with any PWM range . I am I correct or missing something in configuring the switches ?
@@asangag Well 1st and 3rd position is still good! But yeah, the middle one cannot be used, and yes, it is missing the adjustability of iNav... though hardly a reason not to use Ardu as it is by far the superior code, at least when it comes to planes!
hi ArxangelRC , have you had any issues with rf noise on 433mhz from the 765-wing with your dragonlink system , Jetpilot points this out on rc groups and i can detect some in my build but not loads , be good to no your views as you must have done a good few flights by now , great vid by the way
Thanks! How exactly can you detect that interference? I have heard of it... but at this point I can't really say there is, or isn't any! How do you know if there is, since you can really only do this in flight I assume... and the flight controller should be working at that point!
Hi,im new to ardupilot,but i have a problem with omnibus f4 pro v2.ekf show red velocity_horiz and pos_horiz_abs error even i have 17 sats hdop 0.6( compass disable).srry my bad english
I would assume it is showing that while sitting on the ground, not moving?
@@ArxangelRC yes,not moving.is that normal?😅
@@maybayson4203 Could be! Throw it in the air and see if that error goes away!
Brilliant video I have one question I disabled compass as you said but my heading is now 45 degrees out?
While on the ground, stationary? Or while in the air, flying?
@@ArxangelRC on the ground
@@nuforuk Well that would change once in the air! Give it a try! :P
@@ArxangelRC will give it a go many thanks
@@nuforuk Good luck! With compass disabled what you are seeing is whatever it can guesstimate from the gyro, while stationary! Once moving direction is estimated from the GPS, so it will work fine.
Great guide!
Does the camera switching also work between a fpv camera and a gopro/mapping camera?
What camera is seen @17:24?
Thanks!
The switching would work between any two video signals connected to the controller, either both PAL, or both NTSC! If you have an analogue video out of your mapping camera, for instance, if you will be using one, you can switch between the FPV cam, and other cam, yes! The one I have in there is the FireFly 8SE: bit.ly/Firefly-8SE put it there just for the fun of it, to pretend its a mapping camera, but also to do at least something in the way this plane was meant to be used - to have a downward facing camera! :)
@@ArxangelRC Thank you for the quick response!
Alright I see, I dont have a mapping camera, but now I know how the switiching works.
Have a good Day!
@@niklasengler3622 You can use any camera, as long as it has an analogue video signal, so you can plug it in the flight controller! You can run two FPV cameras - one in the nose, and one on the tail, or an FPV and an HD camera, like I am, and as long as you can get an analogue video signal out of the HD camera, you can also switch to its video feed.
Thank you
You are welcome! :)
Arx have followed your channel for some time now thank you would these parameters be the same for a H743
No
Actually they would be, at least as far as I've compared the UART port mappings, all other setup is pretty much the same across everything Matek with built in power module and OSD! Camera switching settings are also the same for it.
Great!
Thanks!
Rc options were always there, just in full parameters list.
Well sure... but there was no explanation next to them, no info on how to use them!
@@ArxangelRC true, and new UI helps for sure.
I just wish they could make it so 2 functions could be combined on one channel.
@@AntonKhrapov Yeah, that would be nice... BUT... could become more confusing in some situations - when you have two functions on each switch, and you have two switches... in any position of the switches you will have two modes selected at the same time... sooooo... which one takes priority?!
@@ArxangelRC there are already rc_options there that might mess up with some flight modes in the same way. I'm thinking more in a way of combining modes... for example I lake to have 1 switch doing RTL or just Land mode depending on setting. It's a 3-position switch that does nothing when it's in the middle and switches 2 separate channels in top and bottom positions, with rcoptions for those channels assigned to rtl and land respectively. So, that takes 2 channels instead of 1 to do this, which is not ideal. Just an example. Switching A and B type of FBW would be another option, or many other mutually exclusive functions.
@@AntonKhrapov Right, I see your point, but it will need to be made like in Betaflight or iNav, to be able to tell it that middle position is neither, otherwise as it stands now... I am not sure you can do just that, but I wouldn't mind them reworking that particular part of the firmware to be more iNav like, because that is probably the only thing I prefer in iNav over ArduPlane!
My question is can you power a h743 wing fc with lipo while fc is plugged into USB on computer
Yes
Yes, not a problem.
I am using the f765 in a Phoenix 2400 glider with INAV. My question to you is, why do you use arduplane instead of INAV? It just seems to me that INAV is more intuitive than Arduplane.
If you flash Arduplane you can try autonomous soaring with Ardusoar, doe INAV have that?
Dooley, I use ArduPlane because I've been with it for years, and I know it well, also, the base code in it - stabilizing, RTH, auto take off, etc., is MUCH more mature than iNav, and has never given me any issues whatsoever, not to mention that is literally does not need any parameters to be changed or adjusted for any of this to work well out of the box! Out of my experience with iNav... I can't say the same, sadly! iNav's GUI might be a tad more convenient and flashy... but underneath... not the same at all!
I am trying to make the RSSI work but didn't. I did what you have did and it shows me 50 on RSSI but not changing even when radio off
using dragonlink MicroRx
my S-bus channel is 7 , flight mode on 5
any idea ?
Well... a good deal of info missing here! Have you programmed the DragonLink receiver to output the RSSI on any channel?
@@ArxangelRC yes it is on channel 8, analog RSSI. Or shall I choose Digital RSSI?
OK... so there is your mistake! On the left column in the DragonLink config tool is your PIN outputs, if you have selected Analogue RSSI there, in the RSSI settings you need to select as RSSI_TYPE the "Analogue pin" option, and then set the voltage range accordingly! The RIGHT channel column in the DragonLink tool is the SBUS channels, and if you want to have it on a channel there, needs to be set to Digital RSSI, assigned to the appropriate channel!
@@ArxangelRC Thank you so much . I got it
@@redsharkss Awesome! Good luck!
are they discontinuing them permanently?
Sadly it may appear so due to the chip shortages!!! :( I was bummed out too!

Also when I put in return to home it doesn't take over throttle like inav ,is that normal?
It should take over throttle...
@@ArxangelRC I reset all the parameters to default must have switched something by accident now it works, If I put it into return to home manually not fail safe It doesn't take over throttle Is that normal
@@jimmytheriot8978 There shouldn't be any difference in how it gets to RTH - Manually or Failsafe... it should control throttle!
@@ArxangelRC I can put it into RTH manually And kill the throttle or give it 100% throttle But it will not maintain a constant throttle in manual return to home Only in failsafe return to home, comma guess I'll try to play with it and see if I can get it figured out
@@jimmytheriot8978 That sounds weird... wonder if there is a parameter somewhere for it! Never seen this behaviour on ArduPlane... it shouldn't be like that by default! Not sure what to tell you... go through the param list and see if there is a setting for that!

Thank you!
why only 8 x servo outputs in ardupilot ??
Well... Mission Planner allows for that many to be setup in that tab, rest can be done in the full param list I guess... would be nice if they update that and bring more of them out to that tab! Would be useful and convenient!

Hi Arxangel, nice video. quick question - are you using 433mhz DL version? If so, have you experienced any range reducing interference from F765 on the DL433 system? Mike from DL says that 765 generates really bad RF pollution that limits DL range. In my experience the range was really bad - i got consistent failsafes ~ 700m from home location in a certain spot. I wonder if your experience confirms that assertion. thanks - an example few secs into this OSD footage: czcams.com/video/H2Ap9AYKMQU/video.html
Right... well I've only been a few kms out with the Flying Dragon so far, but no issues as far as I've seen! My receiver is about 15cm away from the F765, and the antenna is another 5cm, so 20cm in total away from the FC... I guess! It is the 433Mhz one, though I now have the 915Mhz one as well, but that one is in the Aggressor... and out on the wing... so quite a bit of separation!
@@ArxangelRC thanks. I have ~40 cm separation. DL will be soon releasing new firmware in an attempt to try and fix this situation with matek. The issue only impacts 433, not 915. My crossfire models with h743 (same thing as f765) are faring much better even on a lower power level.
@@mkolesnik OK, nice, I hope Mike will be able to sort it out! I am running quite an old firmware on my 433Mhz system... so may go out and do some testing next week, to see if I can replicate the issue! Have another plane to fly and review before that though, will test it next time I am out with the Flying Dragon!
FC Matek f765
I am facing problem with GPS connection
I have connected my GPS to UART port 2
And also set the serial 3 parameter to 5 for gps still no gps signal ( Missing planner is getting only compus signal ) no gps
Did you try changing the places of the Tx and Rx wires?
@@ArxangelRC yes i have tried
@@sainathdesai4081 Well... could it be the GPS unit is faulty? What does Mission Planner say in the bottom right of the HUD on main page, where it shows the GPS status - "No GPS" or "No Fix"?
@@ArxangelRC It say no gps.
But i tested my gps with other FC like APM 2.8 it is working fine .
@@sainathdesai4081 OK, so it says "No GPS" no matter how you rotate the Tx and Rx wires? Can you try moving it to another port then? Use the port for the second GPS, see if it will work there.
There’s a lot of talk on the Dragon Link thread in rcgroups about how noisy this FC is and how bad it effects the DL range - what’s your take on this issue ?
I would like to hear more, since I'm using 765 I've changed several antennas on my DL and range is severely impaired like 5-10 instead of 50-60km. Also it seems that ppm signal is with extra low resolution and 200-300ms delay. I don't have problems on my other setup with minipix with DL too.
@@oneistar6661 same here - see my post above
I don’t use Dragon Link (MFD Link, a 433 system that is very similar) but my range has been stellar with this FC FWIW. I wonder if it has to do with noise being produced by the on board BECs at certain voltages. I use 12v for the VTX...
I've not been out to more than a few kms so far, but have not seen any troubling behaviour from the RSSI indicator. How far away from the F765 are your receiver and antenna?
@@ArxangelRC Hey, Receiver is 20cm away from FC and antenna another 30cm so 50 cm in total. Getting around 40-50 RSSI at 3km and low 30s in around 7km, was scared to go further.
All grounds in the FC, so this might be issue is it good idea to apply capacitor at bat?

Love your Videos, but I Can Not watch your soldering skills
Oh, why not? Please do tell!
Hi...realizing that this video is 2 yes old, and my Google search lead me here, I've seen many of your videos and they're very impressive!
But since I was doing a search for wiring, I was hoping I could get your assistance...
Do you have a wiring diagram (pics) that shows the wiring for dragonlink 1000w rx to matek f405 wing v2 ?
I've built all my planes and diagrams saved me...can you help?
Thank you
Hi, well I don't have a schematic, but the 5v rail provided for the receiver, which should be somewhere around the Tx6 pin, which is the SBUS one, is not powerful enough to feed this receiver at full power! Solution is either to limit it to something more manageable likt 200mW, or to plug GND and 5v to the servo rail, provided you have it at 5v! The receiver will not take more than 5v, if memory serves.
@ArxangelRC ...understood...so the servo rail provides 5v power unless I do the solder bridge for 12v...correct?
So if I do power the DL from the servo rail, as I've seen in rcgroups from one flyer, how does it get the mavlink connection for telemetry in mission planner? Or does that happen just thru the servo rail?
By the way, thank you so much for that incredibly quick response sir!!
@@theroc495 The servo rail, where you connect the servos, can be 5v, 6v or 7.2v, it does not have an option for 12v. The 12v would be the Vtx and Camera pins, do not connect to those. The Mavlink connection is a separate one, and it is a bit more complex there! You will need to program one of the GH connector pins on the DL receiver for Serial In and Serial Out, which would be Rx and Tx respectively. Then on the F405 you need to connect these to Tx2 and Rx2. As usual they need to be crossed, so Serial In on the DL receiver would go to Tx2 on the F405 and the Serial Out on the DL receiver would go to Rx2 on the F405. Make a note of the Baud rate of the Serial port in the parameters of the ArduPilot firmware, by defaut it should be 38, you need to set the DL receiver in its GUI to 38k baud rate, and you need to also set the DL transmitter to that baud rate as well. Then, depending on how you will connect the computer to your DL transmitter for telemetry, could be WiFi, bluetooth, or cable, you would need to select the correct baud rate in Mission Planner of QGC, and it should work! DL have a pretty detailed guide on how to do this on their website, you can check it out there as well.
@ArxangelRC ...very deep info sir, and is a matter of fact, I use a switching BEC straight off the batter to supply 12v to vtx and camera (minim osd as well) with crossfire setup that is now DL...I read in rcgroups that those that fly with pixhawk cube don't use the servo rail to power the DL, but opt for a 2s battery for dedicated power. Someone in the group mentioned rf noise associated with power from pixhawk to DL, so I don't know about that since I'm still acquiring new hardware for the build.
As far as good instructions and information, I look to your videos and a few others for build and parameter info.
I 150%, thank you for taking time to go into such detail on that answer, and although I'm getting up there in age, I hope that I can fly long range one day, as you have achieved...!!
Thank you sir
@@theroc495 You are welcome mate, I do hope you get to your goals! Yes, generally using the servo rail will introduce some interference, but a separate battery introduces a bit more fuss and one more battery to look after for every flight, but it will give you the cleanest power source for the DL receiver. I now see in the receiver specs that it can take up to 8v, so a 2S battery will be OK to power it for cleanest power.
