I suspect my first method for tuning PID loops was not a great hit because it required 3-view drawings or photos of the aircraft plus inertia data all of which is a bit fiddly. I've now got a new method based on flying the aircraft and logging accelerometer and gyro outputs in response to elevator, rudder and aileron doublets. This method works well with simulated data and I'd like to try it on real data. If you are interested in this experiment, let me know your email address and I'll send you more information and a short test specification.

Hey george. I'm doing a graduation project involving the system identification of a tricopter. If you could e-mail me what you have already done it would be very useful to me! Here's my e-mail address: hosts2000@yahoo.com.br
Thanks!
Hi George,
I'm very interested in your work. Could you send me more information on my email id below?

Thanks and best regards,

George, what is your approach? Are you planning on eigensystem postprocessing for system identification or something similar? I've had that on my long term to do list.
I'm interested to hear how it goes, and if you want to bounce any technical aspects of it off me, just PM me.

Thanks Chris yes that is a well explained PID tuning but i think HEAD_MAX in the Mission Planner PID controller dashboard is called BANK_MAX, correct?
I've updated the APM manual to give a more complete guide to PID tuning here.
