A truly legendary explainer video about AutoTune. Thank you sir. I have a few question. 1- Should we reset the AUTONUNE_LEVEL value after the flight? 2-I read that an autotune flight takes 15-20 minutes. My battery is not enough for such a long flight. Does it really take that long? 3- When I autotune for the second time, are the initial values deleted or retained? And last one :) 4- Do I need to do the roll and pitch movements in a single flight? Would it be correct if I did roll in the first flight and pitch in the second flight?
Setting up an arduplane Quadplane on 14S, with separate lift motors and batteries, the lift motors use high C rate LIPOs, and the forward flight motor uses Li-Ion battery. Using Pixhawk 2.1 and wondering what power modules, (mauch?) to use, and how to set it up. Seems the mauch sensor hubs sum up the current from the batteries, and also expect the batteries to be in parallel. How to use the batteries separately, monitor them, and power the pixhawk? using 12S lipo and 12S Li- ion. at end of flight, the lipo will be at min 3.3v per cell, and the Li-Ion will be below 3v. per cell. Thanks for any suggestions, my friend. I would be happy to fly with you someday!
Hi, not worked much with vtol fixed wings with Pixhawks. We've built our own autopilots for vtol fixed wings. Not sure if I'm qualified to respond to your query. Would definitely love to fly with you sometime.
@@DhruvArora I hope we get the chance to fly together, or work together as well. We may in the Future! You helped develop the Thresher VTOL, correct? are you still involved in. the project? My project is similar in some ways. What flight controller was that using?
I really dont know principle of autotune. Ưhen you wrote “every 10 seconds the autotune system will save the parameters you had 10 seconds ago”. So I dont know what these parameters are? And does it always change?
sir thank you for make such a video. But i have very large planes in flying wing models there planes is not possible to auto tune mode so how can given the tuning values
Thanks for the video ive been struggling with the tune of my plane for a while now. When i put it into autotune or any autonomous mode it goes up and down super crazy making it do flips and crazy stalls and nose dives. Any suggestions?
I had a similar issue once. Turns out that the controller was controlling servos backwards. I had my controller set up so it flew correctly in manual mode but the Pixhawk was all backwards. Make sure that in stabilized mode on the ground holding the plane in your hand that the controller is fighting the movements that you do to it. If you hold the plane and bank it left does it move the ailerons to bank it right? If not then that servo set needs to be reversed in the Pixhawk. if you pitch the plane nose down does it move the elevator to try to bring the nose up? If you yaw left does it try to yaw right? If not then you have servos set up backward as far as the Pixhawk is concerned and it will fly all kinds of crazy.
thanks for your video! i saw in the page of ardupilot.org and they recommend to calibrate te airspeed sensor before the autotune, do you know if there is a impact in the calibration of the pitot in the same flight of the autotune calibration? and another question: in the autotune flight, how do you change the direction of your flight without impact the records? regards,
@@DhruvArora Thanks for your quick response! About the second question i mean if it is possible to change the direction of the flight during the autotune, or the calibration should always be done in a straight line
Best explanation of Autotune that I have seen.
Thank u
Pls share your WhatsApp number for more details.
Thanks for your Video! I never Autotuned my Planes but will try it like you did
thankyou for sharing your experience, now i know how to autotune
Cheers!!
Knowledgeable updation 👍

@@FPVREVIEWS yes, we designed it. As I mentioned, we used our own customized autopilot
does this autotune require an airspeed sensor module?

Very Informative. Great Job (Y)
Thank You
Can you tell me please is autotune mode suitable for flying wing? Or this mode doesn’t depend on frame types?
@@BestGorony doesn't depend on frame type

regards,
if arspd autocal is enabled then there is definitely an impact. I did not understand the second part of your question.
@@DhruvArora Thanks for your quick response! About the second question i mean if it is possible to change the direction of the flight during the autotune, or the calibration should always be done in a straight line
@@italogiulianomolettolobos8879 you can change the direction and go around in circles
