I've been searching around the forums and I am still stuck with something I could really use some help with.
The APM I am using came off of an old 3DR quad and I did try the PID settings without any luck.
Recently I bought one of these 3DR DIY kits and I am using the following:
3DR APM 2.5 w/external compass/gps (trace cut on APM board)
3DR 880Kv black motors
QBrain 4x20A ESC (all calibrated)
3S 5000mAh liPo battery pack
10" APC Props from 3DR
The apm was on an older 3dr quad, so I reset everything to factory defaults. I also upgraded to the latest non-beta firmware I think it's 3.14.
I have balanced the props & motors, calibrated the accel and compass. The problem I am having is that I cannot seem to get basic PIDS tuned right, the defaults make it oscillate rapidly, I tried tuning down various gains going by this guide here http://diydrones.com/forum/topics/arducopter-tuning-guide?id=705844%3ATopic%3A1029075&page=40#comments
I don't know if that guide is still valid but I cannot get my quad in the air without losing control.
Does anyone have some basic PID settings I could at least start with?
