This bundel from XProHeli features the small XPG Brushless Gimbal and the ProGro Handle.
The XPG Brussless Gimbal is a motorized stabilization system for a GoPro HERO, HERO2, or HERO3 action camera. It is designed to help isolate the camera from vibration caused by the rotors to give you smooth aerial video and first-person view shots. It is suitable for the DJI Phantom or similar-sized quadcopters using DJI Naza, Spektrum, or Futaba flight control systems.
Using the ProGro Handle handgrip accessory featured in this bundle you can also use the XPG Brushless Gimbal as a standalone stabilizer for capturing skateboarding, snowboarding, and other types of action shots where handheld, freeform shooting is desired.
