You have to cover the barometer sensor with a piece of non blocking foam because the wind affects the sensor readings (look that your altitude indicator sometimes shows you're 150 meters high when you actually are near ground).
Also you have to set the nav_mc_hover_thr variable to the value that makes your quad hover. It'll be used as base value for the altitude pid controller.
Another thing: You must mount your GPS module on a mast to avoid magnetic interference from the motors (and make a new compass calibration process when you do that). Try choosing a very solid and sturdy mast to avoid vibrations as this vibrations will affect flight performance. It doesn't need to be super long... Just 3 or 4 centimeters above the battery will be enough.
Can you use a piece of tape for the barometer ?
@@MrTheklman11 no it needs to be porous so it can measure air pressure
I get that it can improve GPS performance, however is a mast an absolute must have?
@@ImperialArmour the mast doesn't improve GPS performance. It's for the COMPASS, which is also on the GPS module. And yes, it's required. The compass will not work properly near a source of magnetic noise.
I appreciate the fact that we get a realistic look at what issues we'll see if we try iNav for the first time. Things rarely seem to go right the first time and when I see videos where they do I can't help but wonder how many takes/edits it took to get it right. Thanks for your expertise, honesty and patience, JB. Keep up the good work.
Exactly iNav's an awesome soft but you've more percents to fail that win except someone give u a complete tutorial like JB's one ^^
On INAV github there's a wiki page "INAV for BetaFlight users". it's a good starting point.
So, normally I might binge watch Star Wars or something, but today !!! I binge watched JB go through all the playlist vids on both Betaflight and INAV. I am a fixed wing pilot learning about these FCs and quads and so on. A tremendous thanks JB for these vids - Super helpful.
Thanks JB, today was the maiden flight of my Tyro119 with iNav. It could not have gone better, smooth takeoff and acro mode flight then switched to GPS position hold - the quad steadied with a slight drift which trimmed out nicely and it was also stable in altitude! Thanks for your awesome instructions and teaching me how to build a quad that I actually got off the ground.
I am hoping we see a video of how this is supposed to work once you get it all figured out. This will help us a lot.
I’m 47 & I love FPV & my cat. The prospect of this series culminating in a truly original experience with Joshuasaurus Rex means that I HAD to prepare a pot of tea, some biscuits & watch on my pc over iPad for maximum screen size...........Let’s do this 🤨
6:23 😳
A few things:
ALT_HOLD and POS_HOLD can be set as separate modes. So you can check POS_HOLD while managing altitude (throttle) manually. And check ALT_HOLD while managing position manually (angle mode). I would say, check POS_HOLD without ALT_HOLD first of all. Once you can trust it, put ALT_HOLD on a separate switch so you can work on it independently. Best done line-of-sight in a big field. I usually fly my INAV quad line-of-site as a fun break from FPV.
There are PIDs for both ALT_HOLD and POS_HOLD, with an additional complication that ALT_HOLD can use both GPS and barometer. Seems to me the ALT_HOLD PIDs need work. Also, did you put foam over your barometer to eliminate propwash effects?
it is good practice to put some sponge on barometer, wind from propelers produce huge ammonut of noise in alt reading
Ian, my experience with drones has been the Typhoon H which is 3-year-old kid easy to fly. Am doing my first FPV build now and would like to be able to flip on Typhoon-style stability/alt-position hold when necessary until I am a more confident pilot. Is iNAV at this point now, or is it still a work in progress?
Creepy Mouse my first ever build was a crappy DJI F330 frame, Matek F405CTR and a Matek GPS/Mag. In my experience no budget 8inch flies perfectly but mine flew pretty damn good. AltHold and AltHold+PosHold worked rock solid, RTH and WP worked just fine too. I was really disapointed with Joshuas results here. INAV is almost as good as Betaflight in Acro and if Baro works ok and the Mag is mounted good it should be allmost as locked in as a Phantom.
Sorry sure you’re swamped with comments on this one. Likewise good to see you on inav! I have a cunning tip I use regarding getting the GPS lock. If you wire the GPS to a pin which is powered whilst connected just to USB, you can plug the quad into a power bank via USB and leave it for 5 mins or so whilst setting up tx/goggles etc and it should have a nice healthy lock uninfluenced by VTX noise (which also doesn’t have time to get hot!). Then plug in flight battery and you’re off. Works for me especially if I haven’t flown for a few days and the GPS needs new almanac data. 👍
thanks for the tip!
Best part about this series is you experimenting with something you aren't normally using. Your format is much better and refined than other reviewers or how to pilots and I think thats why everyone asks you to do a tutorial for various things. Keep doing new stuff! Maybe you should try a wing out some time. Bet you'd have fun doing a little long range.
One of the first tutorials I watched on YT was JB setting up modes on a Bixler, but I agree that I'd like to see him have another go at fixed-wing one day... ;)
„You want it tight, but not tight!“ ~JB.... love it
There is also a setting that determines at wich throttle level the quad keeps its altitude. You can choose between mid throttle or throttle level at the moment you activate altitude hold.
With the first option the quad should hold altitude when the throttle is at the mid position ( around 1500). With the second option the quad holds altitude at the throttle level you had when activating altitude hold. So in this case when you activate altitude hold at a throttle level of lets say 1300, it will go up when your throttle level is higher then 1300, and go down at a level lower then 1300.
But to be sure (I just recently started putting iNav on my Tyro129), aak Pawel or take a look at Painless360’s channel.
Thanks for that! I built an DJI FPV INAV quad myself and am actually pretty happy after a few days of fiddling around... your tip clears up some dark spots for me. Thank you.
You need to use blackbox to see your acro throttle value for hovering, and input that into the Advanced Tuning tab's Hover throttle value. Also, you can adjust the level strength. Also note, climb, pitch, and roll rates/degrees in pos-hold are adjustable also in Advanced Tuning. The defaults are slow
Love me some Bardwell. "Yaw even works without props on" is pretty funny... Viewers: have you ever looked into what ALL causes yaw on a flat-plane quad, or why you can control dive pitch on an RC car? Inertia attached to a flywheel... I'm thankful for this video series... it got me into flying!
Love how he uses the drone as a selfie camera
They used to recommend a piece of porous foam over the barometer, to keep the prop wash from affecting the altitude.
Cover the barometer chip with a piece of open cell black foam. The chip is light sensitive, heat sensitive, and prop wash sensitive.
Put some foam over the baro. I have a project quad for campus stuff and its running on an spracing f3 acro, so i added a ms5611 baro using i2c and put lot of foam over it and tape it arround leaving just a little hole so it should still read the altitude correctly and im surprised how good it maintains altitude. I also changed the throttle setting for my althold mode so the mid position is about 25% throttle because when i use the 1500 (50%) throttle the moment i arm it'll lift up quickly even with no throttle. Im so new to this quad stuff but after i figured that baro problem out, man do i got hooked into this hobby...
you DID turn on altitude hold while in position hold right? also, you obviously need to tune the throttle settings for your hover point etc. also, you probably have to put some foam over the baro to stop propwash from screwing with it
In the docs, I think it says navposhold automatically enables althold and it's not nessisary to manually set it. I'd bet the hover throttle is also set to 1500, which made mine a bit unstable since my hover point was closer to 1280.
@@wardnb I thought the same
I know many people mentioned putting a piece of foam over the barometer, which kinda makes since(should be built in), but maybe the idle speed being that low on an iNav quad is causing issues. Just a suggestion. I plan to set mine at 10%. I also made many other modifications. Different frame. Because I hate the Tyro frame. Went with a $30 7” Source One. I was also forced to replace the motors, because it smoked one of the motors the very first crash on 6s. I’m not waiting a month and a half to replace one super cheap motor from Banggood. I also chopped out most of the terrible plastic wire, using race wire with silicone. That was before the motor nearly caught on fire. I personally would not run 6S on those motors. The quality just is not there for the higher voltage. I am not the only person that has had this issue. I saw a comment describing exactly what happened to me from somebody else. First crash/smoked motor.
All these comments about baro sensors and gps but I havent seen one about COVERING THE BARO WITH FOAM. They are sensitive to light, wind, temps and foam insulates from those issues. Also your pos hold is a mix of baro and gps data if gps enabled. If gps is not mounted off back of quad with 3d print holder or on a mast it may get bad data. This may be theoretical but many in inav group have tested and believe it to be proper setup. Dont get me started on using a gps compass...disable it for inav and be sure to download opentx inav transmitter glass cockpit!
I’m a bit disapointed. My VERY first build was a crappy DJI F330 frame on INAV but AltHold, PosHold, RTH and WP worked rock solid. I now have 4 quads on Betaflight and 2 on INAV and the difference is mostly related to physics not firmware/software. I actually expected more here so I really hope for a video where everything works flawlessly.
I have enjoyed watching this playlist and following along with you Joshua. However I have come to the conclusion, INav is more suited for RC planes ( just my opinion ) yes it's ok on a quad for a bit of fun trying to get P Hold and RTH and other stuff. But if you want that bite the bullet and get a good DJI system. For freestyle quad flying betaflight all day long.
That being said I Tip my Cap with admiration to the pilots who spend months setting up INav on a quad to make it fly like a DJI system.
18:30 what a beautiful "ESC song"!!!
Hi Joshua - thanks for this series - you have helped me put iNav on my Tyro129. Today will be maiden flight......
I wish JB made fixed wing tutorial videos...
Joshua , Did you manage to sort out altitude hold on this quad ? ..... Diolch 👍
Does your flight controller have a barometer? If so is it a windy day, that can mess with those due to the bernoulli effect, and turbulence in general. It causes the pressure on the inside cavity of the MEMS device to suddenly drop, making the drone think it's rising quickly, causing it to drop altitude quickly. Put some open-cell foam over it to provide resistance to air flow over the sensor.
I am also going to guess your GPS receiver isn't the best. There are a lot of crappy GPS's on the market and it's hard to tell which ones are good. I have had OK luck with the RadioLink ones, they are cheap and good enough.
Thank you so much! I am trying to build my first quad after seeing all of your inav tutorial videos.
28:31 Am curious if you revisited the INAV setup to understand the baro/altimeter issue?
Think comparing Betaflight and INAV to declare one better is the wrong approach. It would be better to highlight the strengths of each for flying style, or type of quad to use on.
The best thing about props out is if you hit a tree it tends to push you back out when props in tends to drag you in and you get stuck. Since I switched to props out I have not got stuck up in leaves or branches. It’s handling seems the same to either way
I'm running 4S 1800 mAh Talon FAF batteries on my Tyro 119, and I'm getting about ten minutes of flight if I'm just cruising around slowly. I put an R9 receiver on it, and finally got around to testing some longer ranges today. I was able to get out to about 1200 meters or 0.7 miles before I decided to come back because the terrain made line of sight for the antennas impossible past that point, RSSI at about 88%. The video transmitter was at 600 mW and the R9M module was at 500 mW. The video signal was still good at that range.
it would be really good to see a video #9 in this series with the kinks ironed out on this quad. please? :)
Absolutely agree! Come on JB, give us an update!
Great stuff. Building my first quad following this tutorial. Ur the best JB. Greetings from Greece..
Yea! You are a great asset to us, thanks for the build, hope to see your results from the talk.
6:50 you got your convex/concave muddled. Think of a concave surface as being like the walls of a cave.
beat me to it!
@joshua it actually can do a good hold and waypoinst. At least that is my experience over the past 6 months. You should check your hover_throttle, so the quad rufly knows what hover throttle is. Also cover the barometer with some foam to prevent jumps from passing wind. IMHO 2.4 latest was the best at holding tho... the 2.5 is a bit twitchy when in pos_hold. Nice vid and tutorial tho!
look forward to the next one
Pretty fantastic job, Joshua!!! 😃
Flies pretty nice! 😃
Stay safe there with your family! 🖖😊
Joshua, we are all waiting for the resolutions to your INav issues. 🤭 Have you been able to work through them yet? I have a 5" I would like to 'convert', but, before I do I would like to know the 'little' things that I will also have to address.
love to see JB on inav!! I use it on all my wings. RTH ,WP etc are all awesome features for inav especially for my wings.i have never tried it on any of my quads yet even on my 7" lr build always used bf. being familiar with inav and interest with putting on a quad im excited to see you dabbling with it.
I use GPS in all my builds from 3 to 7 inches and it takes some time working on Inav and the CLI screen but with the help of pilots like Josua, Pawel and others finally works perfectly on all my quads... It provides you and additional safety and the possibility of better images and videos.
Anyway i recommend all of you use GPS with magnetometer the behaviour is much better. In Betaflight is not neccesary but the RTH landing is very rough.. Only valid to return the quad... Enough for our quad safety clearly, but when you see how Inav landing mode works, is another planet.
For me is clear that Betaflight is perfect for free style and Inav is better for soft flight and navigation, photo, long range etc.
Hi Josh, just watching this and noticed you had no trainers on. I had a new build a few years ago and had my sandals on, next thing quad went ballistic , bounced off something and next thing I knew two of my toes in a bad state. Two hours in A & E. JUST SAYING BUD.
Very useful vid for any new people. Nice sound effects! But the bottom of the prop is concave, and the top is convex. 😬
Hi, thanks for the videos,
I think you need to try the new iNav 3.0 that have all missing features like turtle mode ...
LOL - keep'm coming Josh! Enjoy your day!
Joshua, thank you... I see this was published over a year ago... I went through each video to get to Part 8 so that I could use your guidance to resolve my GPS Hold issues only to find that Part 8 shows similar problems as what I have encountered and.... oooooo.... noooo... it's the last one.... I have mounted my GPS 3 inches from all other boards and wires.... confirmed my compass headings... and even tried tweaking the PID values for GPS only to find it has a mind of its own. I have captured black box only to realize I have no idea what should be compared or what looks irregular... Please do another video to track down GPS Hold issues... That was my reason for trying INAV. Thanks in advance!
Now it's time to give ardupilot a shot!!
Maybe a pixhawk controller or flash an omnibus or matek FC with ardupilot.
Nice build. I sadly due to my poor piloting skills crashed and burned my down. lol. It did fly nice before the crash though. Happy flying
Hi Joshua. Excellent series. What would be cool is a video on Props-out for iNav. I watched the one you did for Betaflight. Very nice! In iNav it's a bit confusing to me because there are reverse motor settings in the Outputs section and also in Configuration there is a Reversible Motors area and also a setting in Other Features for reversible motors. If you have time, it would be cool to see how it's done. Thanks!
@Joshua Bardwell - great series. I'm interested in converting my impulse 3-inch freestyle from betaflight to iNav... I have a 4-year-old daughter who is very enthusiastic at getting my attention while flying ... a position hold button (pause btn) would be a godsend!! Does anyone know how far iNav has come in the last 2 years regarding flight performance? Will I notice the difference from betaflight while enjoying proximity freestyle?
Yaaayyyyy!!! It works!!!!
Sooo......
Props In versus Props Out; if going from one to the other on a 'tuned' quad, will it make a difference to the PID set-up/tune?
Would it need a re-tune/could I smoke a motor/fry an ESC by going from one to the other & not changing PID tune???
Thank you once again :D
Naaa you'll be fine going either way it probably won't change your Pid tuning or make you more likely to smoke a motor I just wouldn't worry about it, with this quad atleast, it doesn't start effecting things Untill you get super small quads, but if you want to try it's not that hard to change look at JB props in VS pops out video he shows how to try it
How heavy is this quad with 4s batteries but without any go pro or such thing??
Please, anyone?
The bottom of a prop is concave, the top is convex. Got it backwards in the video :)
Joshua I seen that you were using rdq 1500 for sale I recently started using those batteries and they're the best that I've ever used
Joshua cover the barometer with a small dark foam and tape
@Joshua Bardwell its a shame you didn't continue this series because you stopped just where iNav starts to get interesting. I think there would be a lot of value in showing how to troubleshoot the issues you had with position hold and going on to fly waypoint missions. Or should we all just throw up our hands and give up when things don't just work first go?
I tried to fix them but never got it working right. Not very satisfying to release a video that doesn't contain a solution to the problem.
6:45 I'd say you have concave and convex backwards. When looking down on to the prop, if it curves out towards you, it's convex (the top of the prop). If it's curving away from you, it's concave (like a cave, a hole in a hill), the bottom of the prop.
Maybe I'm weird but why the H you go fly it FPV on first flight and were's your PID tuning. Or does it fly with stock settings?
Maybe safety first but like to keep in in hand with a little Throttle and feel if everything works fine.
Mostly battery plugged in halfway.
That avoids the fly away you talk about or getting unexpected behavior in first take off. Which also can be dangerous.
Going to build a inav TBS discovery but also a plane with it.
First putting it on my old tricopter and bixler to get familiar with the settings.
Flying fpv since 2011 and LOS since 1996 so not a newbie.
I'm from the generation who had to walk to the TV to Change channels. But only 3 by then 😂
I love your videos. This iNav series is especially interesting for me. (I have built a 10" drone on an F450 frame, running Betaflight, with camera gimbal but I am still learning to fly/hold it smooth and steady for videos.) What I have learnt is that iNav can well handle an optical flow sensor, too. I wonder if you would try it. Thank might solve the low altitude holding problem. I have ordered a Matek 3901-L0X board and a sonar can also be connected to it in "daisy chain" as I know so I am very curious how that would work together...
I allready installed that Matek Optical Flow Sensor, still need more testing. Kinda works..... have you got it yet and allready made some hovering tests?
@@stephanh1083 Not yet. I am waiting for more components (GPS mast) to totally transform my quad for inav.
@@stephanh1083 And I am planing to install a sonar unit, too (it can be connected as a slave device to the flow sensor as I understand)
I'm not sure if it will work. Sonar connection (Trig & Echo) has not been implemented. This is what the Mateksys site says. Maybe I am wrong?!?!?
@@stephanh1083 I am not sure, I will check it out. www.mateksys.com/?portfolio=3901-l0x
At the end also the rth is better on betaflight than inav 😱
couldnt help but notice your altitude in the top left was super inaccurate, at points when it was decending the altitude was going up and vice versa, so i think whatever you were using for altitude was messing up the fc
A year ago i wanted to build a video quad based on iNav, but i had so many problems (falling from the sky without any warnings in any modes, unreliable poshold/rth ) with it i ditched the GPS and iNav and just flying it with beta flight manually... I giving iNav and my old gear a second chance on a land vehicle now... maybe it got better...
So for me
What I do is I put a price of sponge over the barometer and the altitude hold gets better..
Still it’s crappy
Hmm that's kind of silly they don't do that when it's manufactured imo. In my Kakute F7 they put foam under the gyro, so why not the baro too?
Hi, to fix the compass orientation problem, can simply see the model orientation in inav. If upon tilting the model, the model swivels, the compass orientation is wrong. In settings, one can then choose the orientation that prevents such swiveling.
Love that 👕
I think you have iNav setup and wired the GPS cables wrong. The TX and RX coming from the GPS needs to be this way:
GPS RX = goes to the TX on the flight controller.
GPS TX = goes to the RX on the flight controller.
Also, place a tiny piece of foam on the barometer, change the return home to 3 feet high to test the return home on your backyard, make sure there is nothing on the way. If your quad is not solid hovering in one place and the return home does not work 100% every-time, you have wired or configure something wrong.
All I can say is the way I show the GPS in the video worked.
@@JoshuaBardwell Based on the video above, the GPS with the data did not work. Check the GPS cables' RX and TX, it could be that they are soldered wrong. They can not be the same on the flight controller when soldering. The GPS TX cable must be solder to the RX of the flight controller and the GPS RX to the TX of the flight controller. Now, change the height of the return home to around 2 to 3 feet with the turn to return direction enable to test the Return Home. If you have everything setup right, your quad should stay hovering in place even with high winds... and it will turn to the home direction when you press return. it will land at the same place it took off. Never test a GPS return home about 3 feet high. if the 3 feet high works... then you can change to whatever RH height you desires. I hope this helps! Remember that the GPS needs to send and get the right data or it will do what the video about did or even worse. iNav is amazing when it is setup right.
@@JoshuaBardwell If the wires are correct, check the Mag Alignment... Some GPS units you MUST change on iNAV the Mag Alignment to CW 270 degree Flip on the Configuration. This could be the reason your quad flies crazy and Altitude mode sucks.
@@EfeekGuestGaming He already did that in a previous video brah. He shows how to figure out and set CW 270 flip.
I run 5S for daaaays. Don’t want the weight of 6S and and 4s is a little too under powered for my liking. 5S is where it’s at for me.👍🏼 Tattu 1550 5S is all I use.
they do recommend 5s for the tyro
Anders Martinson oh I just run 5S on all my large quads.
Jerry7Six Nice
The altitude problem might be relative to minimum idle you set from 15 to 5.5 when switching to hold.
I changed that to 5%, although it might have flown by in the video and gotten missed.
I converted my Tyro to iNav, running 6S at 15% idle throttle I could not get the quad back down. Even at 0 throttle the quad remained hovering 30ft up and slowly climbing. After holding zero throttle for 3 seconds in angle mode, the quad just decided to disarm it's self and plummet to the ground. The end flight screen showed, "Disarmed by: LANDING"
I have no idea what just took place. Is this just some iNav weirdness?
you haven't got your mid throttle number right, i have a 2.5 inch one that 3d fixes quite well on something like 1382 as mid throttle which was pretty similar to a five inch one i made as well which was funny.
What are your thoughts on using a 5000mAh 4s lipo battery for this particular drone? I plan to take some cinematic shots with long range cruising, is that better or is there a better recommendation?
21:00 So the sticks don't react until you raise the throttle. I understand that, but what happens when you command zero throttle mid flight? Will the sticks react then, or lock up as well? Documentation is thin on some parts of iNav..
Nice shave, J! :-) And nice vid as well!! Thanks!
I had same problem with gps on tyro129....I'm really curious how these tests would perform with a decent gps module or at least one with a consistent barometer.
Curious🤔 I am working on a new (my first) build and will be installing iNAV. Would you should just to never utilize a GoPro because of satellite confusion? Or is there a way around it?
Did you put foam on your Baro? Otherwise it will really have trouble to guess the height.
HI Joshua...so when you turn off your radio your motors are stop but If I have gps and RTH setup to back home do I still can check my failsave this way like You?
It take 2 months to put the Inav GPS stuff, to get a "fly pretty good in acro". Nice.
Hey Josh, I got another question. In angle mode the drones throttle jumps from idle to like bye bye and I have to hit the kill switch. I don’t have any in between but it works fine in acro mode. What am I missing now? Lol!
iNav dont's arm. How fix, some tutorial ? When iNav new release arrive ?
Yasss
i've been wanting to switch to inav for a while now and stumble across this tutorial. but seeing this makes me think twice. that was scary. let's not fix it if it's not broken :) .
i got it working with cleanflight 1.14, except for RTH landing of course. just RTH works if you don't mess with the throttle. i think i'll just stick to that.
czcams.com/video/a2OfGy_3myg/video.html and czcams.com/video/JHzqpCa-2iU/video.html
and yeah, barometer reading is all over, needs to be covered with "breathable foam"
When is video number 9 releasing, need to finish my build.
Your build should be finished by this point. The build is finished and then do a demo flight.
What step did you miss?
Joshua Bardwell in your last vid you had issues trying to get position hold and alt hold to work properly. Just wondering if you ever figured it out.
Sir i need your help. Am planning for a autonomous quad setup with inav for planning mission do i need a radio telemetry ? Or only GPS with compass is enough please help me am in a great confusion
Ever figure out the altitude thing?
Hey. This is INAV. Set your failsafe to return to home and land
Not until I verify that RTH actually works.
I have been watching this whole series just to know about the autonomous flight but got nothing about that 🤧
Is it possible to get AGPS in the fc to make the gps lock faster? It helps a lot in my running watch it I have agps updated with satellites in my location
What caused the altitude issue?
9:31 No you did not link the video :/ i'll find it. Also sound is out of sync.
I was thinkink about a comparison, i saw you used two Ummagrip, and i was wondering if you stack the nano grip silicon phone holder ebay 1$ a piece, even with large pieces (Car Dashboard Nano Silicone Anti-Slip Pad Sticky Grip Mat), how would compare to Ummagrip.
That's because this is copied from another video and the original link is in that video.
@@JoshuaBardwell Sorry i dod not notice the, i was mostly just listening it. Also now the sound is good, so it might was only in my side. But is there any simmilarities between the stacekd dashboard silicon and ummagrip?
I might have missed it, but it looked like it "modes" you only had position hold enabled and not alt hold??? Not sure if when position hold is enabled, it automatically engages alt hold but believe you need to also enable alt hold independently .
Wiki says that poshold activates althold automatically.
@@JoshuaBardwell In this case you should activate "auto throttle and throttle " on the osd and
check what failed. I think your baro is unstable. I remember " should I place height? No I don´t need .." ;-)
...oh dear, I forgot to thank you for all the series and single vids I wathed since years, just for YOUR way to present all informations. Keep on.
@@JoshuaBardwell Ok, thanks - I was unclear on that...
for gps reliant fc, i might just go back to pixhawk.
A new version of INAV was just released. Like literally days ago. Are you using the latest 2.5 firmware?
No this video was recorded a few weeks ago.
@@JoshuaBardwell Lol. You are already obsolete man, get with it! 🤣This hobby moves too fast IMHO.
Did you do another video fixing the issues as you said you would?
I haven't been able to fix them. So I haven't updated the video.
@@JoshuaBardwell Did you try the covering the barometer with a piece of foam trick that everyone mentioned? Seems like all of the problems in the vid stem from the fluctuating altitude.
So flying 4S is like giving a 4 Cylinder Mustang to a 16 yr old. Perfectly safe :-D
Hi Joshua, had my first inav 7” flight today but soon as I switch from Stab mode to Acro the quad shoots off sideways. Any ideas on what the problem could be?
The first thing I would ask is, do you have any experience flying in acro mode?
how did you fix the home arrow pointing in the right direction?
Go to part 6.
@@JoshuaBardwell Thanks for the reply, part 6 only discusses setting up modes and your transmitter, I've watched that video. What did I miss? My home arrow never points back "home" but my distance to home is very accurate.
Does the board have a barometer? That could be where your altitude issues are coming from.
Should you turn of the baro if you have GPS?
@@fishfinder3583 Never. Air pressure sensor is far more accurate (unless the FC baro is junk). Matek FC's have better than +/- 0.5m altitude accuracy.
@Joshua Bardwell | Thanks a lot for the series. Just finished my first iNav, went out to test it and got exactly the same experience as you had, iNav was not able to GPS hold. Such a pity! Any idea how to fix this?
You definitely need a working barometer and compass at the very least. And put open cell foam over the barometer.
@@JoshuaBardwell I'll give it a try. Thanks a lot.
Awesome, we did the first flight the same day! Can anybody advise on compass problem: it does not "see" south period. When I go south OSD says 360 and the compass bar is showing N. I tried to recalibrate compass but the problem is still there. Also, is there any way to correct heading other than with fixed degrees like 90 deg, 180, etc.?
I don't know if JB's instructions are quite right, you need to point every side of the drone down and rotate 360 degrees (i.e. front, back, left right, top, bottom). That's what it says in inav at least.
@@mattsupertramp6506 I figured out the problem was you need to keep GPS sensor away from FC and VTX. Once I mount it on a tower problem was solved. Unfortunately (it was quite a while ago already though) I have lost the bird. It was so good at mission and long distance flying that I just overconfidently pushed it too limit and it vanished after low altitude banking turn far away in a jungle.
What's the estimated range on this drone ?
