I have been looking for a 2 axis gimbal, and there are many available for gopro and for the Phantom. My concerns were the angles it could move to, the roll and pitch, and the specs dont say much most of the time. A lot of the youtube shorts, the person wobbles the copter around to demonstrate the stability, but that didnt help. Of course one guy did demonstrate the manual movement, where it could look straight down. Some specs show +45 and -45 for roll, the pitch was +5 and -45? Ish! that wasnt good enough (The Roll was ok, but pitch not) My point is every gimbal I looked at from Aliexpress and Banggood seemed to be for the DJi Phantom. I have no sedervations on putting them on my home built model, Drilling and tapping holes is easy. (All around the $40 mark) All had their own controller with a sensor on the camera platform.
