The 5 control wires for the video relay and shutter release require cable fine enough to pass through the 3 hollow core motors to reach the RC receiver and video transmitter. They have to be flexible and strong enough to take the inevitable tug of war to get them to pass through the yaw motor core where the 9 wires of the OEM loom meet.
The ‘rat’s nest’ appearance is disappointing but it all works, if only briefly before the battery flakes out.
After trying various wires from the scrap bin (iPod headphone leads-poor conductance, cat 5 LAN cable cores-too thick) a discarded USB cable proved to be a good source of fine wire and, with patience the control wires are connected and JR terminals fitted. Stripping the USB multi core takes a bit of care as it’s easy to puncture the insulation with the stripping knife.
Now all 3 systems (gimbal, video and RC) are connected I hit a new problem. I’m draining the battery in minutes. To initialise the gimbal needs full 3s power: 1400mA is required. Powering the video transmitter dents the peak current very quickly and the initialisation can’t complete its routine. I’m going to have to run 2 batteries to manage the demand, a separate source for the gimbal is recommended to avoid Voltage drop caused by RC and VTx demand so the system should be more stable in the long run even though the weight budget is running high.
