Default PIDs seem VERY high!?

Many thanks for your help.
I`m waiting for spare N4 expansion board for logs analysis from SD card. My current frame/motors/M4 is fully unflyable solution with all posible pids (and your too, because quadcopter has big oscilations). I want to find source of problem.

This works for me. See file. 450 size with 920 motors in dead cat. Very very slight wobble when holding, but you could tweak it out probably.

I don't know about too much heat, because I've usually crashed before I get to that point.

All problems was solved when N4 expansion board was replaced with new. Old N4 board was slightly scratched. May be it was source of problem.

Thanks.
I did change frame too. Crashes on TBS Discovery was little expensive for me.

PID`s still need some tunning. Quadcopter rapidly descend at 1-3 meters when I am switching to position hold mode. Could you tell me, how to avoid this?
