Well guys, I think I made a mistake. I purchased a Walkera G-2d gimbal and happily installed it yesterday. I currently use Hero 2's for my shooting and assumed I could just "make them work". Well, I tied them on to the gimbal and it works okay....until you bump it at all. At that point the camera pitches downwards and the motor jitters, seemingly fighting to bring it back up. I did some quick research and found my H2's are 98G while the H3's are 73G. Did I just buy a gimbal I can't use with my GoPro's??
