🌟INAV🌟 Position HOLD 💫 Tuning 🏹

[@selfish1716]

Many thanks for the video, can you please try to tune 10 inches using INAV, you may see it will be very different. We use INAV for bigger drones, that is where INAV is great, so it will be helpful to use the corresponding hardware. A separate video about tunning bigger drones (10 inch) in INAV will be very useful if you want to continue the series with small drones.

Another vote for the tuning a 10in inav series quad. MIne is done and just starting tuning. 900kv motors 10x5x3 prop and 6s. It is a deadcat configuration.

[@davidsmay698]

Another awesome video, super helpful for tuning INAV NAV modes! Thank you!

[@Mupshot]

This is cool. I need to work on my filtering and PIDS in INAV7 before I worry too much about my toilet bowl pattern in this new build and my old one. I have found on both that if I manually set it level and there isnt much wind to fight, they tend to be modtly stable in POS hold, but if I set hold as I am moving, it never comes to a rest. I typically consider POS hold as a pause button if I need to move my attention for a moment.

check Compass Calibration and Compass Orientation setup toilet bowling.

Great series. I’ve been waiting a long time for this 👍👍

[@rocketrob3324]

Such great information, Can't wait to tune!

[@tachyonpost1472]

As always , great stuff on this unique series. !!!

[@John_Doe_6996]

Probably going to switch from Betaflight, and give Inav a try. BF is great, but I really wanna try the fancy gps assisted modes of inav. Also the RTH, and waypoint missions look attractive.

[@John_Doe_6996]

My position hold and rth= vortex of death lol…need to get them sorted out.

[@uavtech]

recalibrate Mag.

[@PIDtoolbox]

this is awesome! thanks Mark

[@PickMe_Gaming]

should I change also the value of the roll, pitch and yaw in the pid gain? or not necessarily ?

[@adilsongoliveira]

Very cool, thanks! As you say, a 5" is easy, a 7" not so hard but I have a 10" and is was a PITA to tune.

[@uavtech]

yeah, the big problem in the props are so heavy for a 10". Takes motors with a lot of torque.

[@selfish1716]

@@uavtech here is a real challenge for you: Would love to see tuning 10 inches in INAV video, it won't be as easy as small drones, starting from ESC, filters, and other stuff. That will be very helpful. You will see that althold, poshold, RTH and smooth flight is much more difficult to tune. With your experience content will be very valuable.

[@uavtech]

All the same principals. I don't have a 10" on me.

[@divingfalconfpv4602]

​@uavtech yea I have 8" on small 7" motors. Doesn't fly well. I just ordered slightly bigger motors this company using on their 8". So I'll see haha. Might have go even bigger

[@divingfalconfpv4602]

​@@uavtech when I build mine. Want to tune it for a video haha

[@divingfalconfpv4602]

It didn't over shoot but maybe cause wind or cause I just put inav 7 in. It was going like 30 degrees left then straight then 30 degrees left.

[@OzgurJohn]

I wish you also work on Ardupilot

[@uavtech]

coming soon.

[@Fleche_FPV]

MORE !!!

[@MrHeretic666]

15:48 Anybody from flightsims? Did you think about that voice in the cockpit of a jet fighter while Mark is sayng this "Overshoot" multiple times in a row?))

[@mhk1058]

Great info thanks. First drone build so catching up but from this I assume altitude hold needs to be enabled at the same time as position hold (ie set to same channel and switch position in modes) or is it automatically enabled when you enable position hold?

[@uavtech]

POS hold automatically triggers ALT hold too.

[@mhk1058]

@@uavtech Brilliant, thanks, good to know.

[@peterhancox5268]

How do you get a ‘position hold’ with a pure glider. I want position hold without altitude hold?

[@uavtech]

pure glider? wing? POS hold triggers Alt Hold. But for a wing, it is a Loiter (circle).

[@volkergoe]

Isn't the velocity just the 1st derivative of the position and the velocitys I term basicly the same as the position P term?

[@uavtech]

Yeah, basically. I'm not 100% sure why there is two loops.

[@javiello]

Hello i can t make it work the outputs- mixer wizard in my cinelifter x8 with t-motor cinestack f7 (TMOTORF7V2( your help will be very preciated! Regards from Argentina.

[@uavtech]

yes, mixer can support octo.

[@Samuelfld1]

Tested my 7inch on Sunday and my Position hold was just tilting backwards and one constant direction and that’s the same with angle mode I’m putting this down to centre of gravity as that day my drone was very back heavy due to me not putting the GoPro on as a “counter weight”. Any suggestions either way? thanks

[@uavtech]

re calibratr and check mag orientation.

[@Samuelfld1]

@@uavtech mag orientation is good! I’ll re calibrate if changing the centre of gravity doesn’t work. Thanks 🙌

[@uavtech]

cog should not drag off pos hold unless you have no I-Term gain in Stability PIDs (normal pids). Calibrate and check cardinal directions in OSD compass readout as you turn to each (N, E, S, W).

[@Samuelfld1]

@@uavtech okay will do, I’m testing it tomorrow. The only reason I’d say it would be COG is because it does this in Angle mode. I have a fat 20 min flight time battery on the back so I’ll put the go pro on anywhere to balance the cog out and then look into calibration and PIDs. I didn’t really PID tune the quad, just turned on EZ tune

[@John_Doe_6996]

Should alt hold and pos hold be active at the same time? And also, should angle mode be active while they are active? I currently have my 3 way switch set to Low = angle, mid = angle+alt hold+pos hold, and up= acro mode. Is this the right way to do it? Or will the gps modes automatically activate stability? When I did a test flight yesterday, my gps modes acted like a drunk person took over my sticks. Unsure if this is a mode issue, calibration, mechanical, or tuning issue. Edit: after doing some reading, this may be due to loiter radius settings. Maybe my quad thinks it’s a plane? And trying to do a 50m circle lol, cuz it would just roll itself somewhat gently to the side, starting a tornado quad effect…maybe that needs to be “0”? Or 1 or a decimal number…🤔

[@uavtech]

no need to activate all at the same time, it does it for you. so activating POS Hold automatically puts it in to ALT and Angle. If circling, recalibrate your mag. Use stick commands in the field to do the mag calibration and save it.

[@John_Doe_6996]

@@uavtechThank you! I followed your advice, and its working sooooooo much better, just need to tune a bit to tighten the hold, it went from flying very dangerously, to flying pretty well. Also I found out my compass orientation in the alignment tab was set wrong, north was south, I'm sure my drone was very confused.

[@uavtech]

@@John_Doe_6996 AWESOME, great to hear! yes, I see the same issue in mag orientation.

[@sullytrny]

forgive me but your cap needs a prop stuck on top
