At Hobby-Wing.com they sell the battery power adapter for powering the CM-2000 gimbal. But can't we connect the power right to the free wire (power from battery) in the arm of the phantom? Do we need to buy the adapter? Also I was thinking of buying the GoPro Hero3 Carbon Fiber Frame for CM2000, If I purchase this for my Gopro hero 3, if I decided to fly without the housing, can I do so as if I didn't purchase the housing. Or am I locked into always have to use the housing. Does it attach to the base somehow and allow me to use or not use at my own discretion?
