GoPro gimbal for full-scale aircraft?

[Curt Thompson]

I’m looking for a gyro stabilized gimbal for a project I want to build. I want to mount the gimbal on the outside of my experimental airplane (Zenith CH701) and use my GoPro Hero 3. I want to be able to point the gimbal in pitch and yaw using RC type PWM signals from a microcontroller. I want to be able to configure the gimbal to stabilize on a particular pitch, roll, and/or yaw (configure gambol before flight with PC software expected). I plan to control its direction (and slew) with a homemade pointing device in the cockpit. The gimbal needs to be able to hold its orientation when the aircraft is going about 100 MPH; survive a speed to about 130 MPH. My budget is about $600 for the gimbal. Does anyone know of a make/model of gimbal that might do this?
