This handheld gimbal is originally made for the SJcam 4000+
Motors I used are: RCTimer BGM2804 100T Brushless Gimbal Motor Hollow Shaft
Gimbal controller: Alexmos 3 Axis BGC V3.3
For the Lipo battery I have made a hole in the front to put an on/off switch
The screws are M3. In the handheld i put some M3-thread inserts for durability.
The gimbal arm is optimized for optimal balance (with camera + accu)
