Would like to stabilize a 500g compact 360 camera rig to a Phantom 2 ... either purchase Vision+ and modify gimbal or purchase regular phantom 2 with customized gimbal setup... as its 360 camera, does not need pan, tilt per se... just steady... and also ideally rig a way for it to drop below skids during flight for clear 360 view...
Sorry, DJI doesn't have this kind of gimbal on sales to support the 360° camera DIY
It's not suggested to modify the v+ as the GCU is matched to use with V+ gimbal and camera.
DJI does not appear to want you to use anything but their gimbal. If you insist then you may need to change your Tx/Rx to gain control of any gimbal you use. As far as I can judge, this is the case as DJI refuse to answer any questions that would help you with alternative gimbals. Well they have apaprently taken to refusing to answer me, and I have been nothing but polite to date. Check this out There are other UTube articles.
