After having started with the DJI Wookong M, I was convinced that the APM 2.5 + would open thousands of doors to the world of UAV systems, for a fraction of the price. I immediately saw how the flexibility and compatability of the ardupilot would make this one of the world's leading products. Well done to all those who made it happen!
I currently use a DJI F550 with the stock frame, motors, ESC, etc... Mounted on it is a small Aeroxcraft Gopro gimbal with of course a Gopro.
Having searched the web for PID settings for this configuration I saw many posts with no replies. At the beginning, I have to admit that I had a few heart attacks with uncontrolable manoevres the machine made. Worst of all was the throttle control which was literally unusable. The copter flew up, and was impossible to keep still. This was a major problem in landing as you could never give the right amount of power for a so called "soft landing".
After many hours of tuning, I managed to get this bird to fly noticeably well. Not to say that it is at its best, but I am certainly happy with its behaviour. These are the current setting I use:
Arducopter V3.0.1 Hexa
Basic PID settings:
Roll/Pitch R.C.: 0.1040
Roll/Pitch R. Damp: 0.0029
Yaw Ang. R.C.: 0.2000
Throttle. Accel: 1.400
Throttle Hover: 384
I am certain that many who begin using the Arducopter would find such PID settings very useful. Could I therefore request on behalf of all those who might maybe need it, for all people with a similar setup to post the PID settings below. It would also allow for experienced pilots to optimize their flight characteristics.
On my latest flights, I switched to loiter with strange events. Once enabled, it starts making circles. These become increasingly large and aggressive up to the point of it becoming uncontrollable. When this happens it is impossible to do any imaging and it is even lethal for the copter... Did anybody else have a similar problem? It would be much appreciated for any comments and suggestions to fix this problem.
