Hi everyone, I have a P2 with Gimbal, mini OSD, immersion tx, and a GoPro 3 BE attached. I cannot get it to have a properly stable flight, meaning it is dancing around, doesn't fly straight, and additionally when going forward it always steers left right, left right. Every second or so it steers by a few degrees left and right. Tried the default settings, settings recommended by DJI support, but no luck. Anyone can help pls ? Thanks.
