Well, it is back together with the Pixhawk mounted on the bottom plate, a Walkera G-3DH 3 axis Gimbal and the HML 650 Retracts.
I just have to figure out how to wire up the gimbal for pan, tilt and a 360 deg rotation, plus it has another cable with it for changing the modes of the Gimbal.
The Gimbal had brushless motors, so i want too see whether i can ruin it of off the X8R rx.
I have also relocated the Battery to the top of the top plate.
u only need relays for hooking up servos, looks like you still have 4 ports left for output of pitch and yaw RC control thru pixhawk
you just need to do the pixhawk gimbel setup and map the input RC channels from radio TX out to the pixhawk output ports (2 of the 4 you have left)
is much nicer if you let pixhawk control the gimbal, as you can point and click the camera on Mission planner and even during missions
