/diy/ - Do It Yourself

So, I've decided to try my had at a custom gimbal for a "camcorder" style handheld camera, to be mounted on multirotors or airplanes. Basing the design around the Canon Vixia HF R400 camera, as that's what I've got, but this should be compatible with pretty much anything in that size range.
I'm really just doing this because my gopro 3 silver is shite and I don't much care for buying another "action cam," while I wouldn't trust myself flying a DSLR rig. But, Ifigure I can make something fairly interesting out of this, It's got 32x optical zoom on it, with a slider that's easily servo-riggable, so it will be able to do things even the DJI stuff cant do.
What think? Going to 3D print, and using https://hobbyking.com/en_us/ax-gm2212-72kv-gimbal-motor-for-200-500g-camera-s.html..
I know balance will be a PITA to achieve, I know exactly where the camera's pitch balance is but the roll one is trickier due to the folding LCD which has to be extended to access live video output :(. I've tried to add adjustability into the gimbal geometry to use the gimbal assembly itself as counterweight, and if It's not enough I can just add coins or something, but it will still be a pain.

What gimbal controller to use? Want cheap...
