I am a member of a French yahoo group on 3D printing. Today a member posted a link to this nice brushless gimbal that he designed for the GoPro hero3 and posted on Thingiverse. he did not reference the controller he is using but he published the design files here.

Julien Watier, I'm very interested in purchasing a couple of these. Do you have any for sale?
Do you plan to sell these anytime soon? Also, do you have camera mounts that support GoPro Hero 2 cameras?
Why not use a camera with a cylindrical form like the Ion Air http://www.iontheaction.com/. Rotate the gimbal 90 degrees so pitch becomes roll and roll becomes pitch, and the roll stepper motor can be aligned with the center of the lens of the cylindrical camera body.
The off center lens should have little or no consequence at the distances (mostly towards infinity) we operate with, when flying copters.
@Ben Norris; Ah, ok. So you would need some extraweight ("Coins") for balancing then. Perhaps the off rollcenter lens is no real issue. Not having any gimbal at all I have really no real opinion on gimbaldesigns.
If your motor is 160C you have bigger problems then the plastic melting..
Sorry for a gimbal newbie question but wouldn't it be better to put the gopro lens in line with the rollmotor axis?
Do these things use standard 3-phase brushless motors or are they wound as single-phase LAT's (Limited Angle Torque motor)?
