Hi,
just a quick question to make sure that I’m not doing anything really stupid :). I have a 4" quad running arducopter. Are the default pid values going to be fine for the testflight or will I experience significant oscillations? Has anybody had some experience regarding similar sized copters?
Many thanks,
Mathis
No, the default PIDs are not optimal for that quad.
Follow the documentation on how to tune the copter and you’ll be fine. It explains it step-by-step.
There are some good YouTube videos by AndyPiper on the topic of ArduCopter for racing copters as well.

Countless people have experience here with small quads and as @amilcarlucas said defaults won’t fly.
