The 12 wire slipring worked fine with servo wiring and with TBU wiring. Used a common ground and positive for servos at full battery V, but your approach to use reg. 5V is better.
Ran power for BP firing gun through a single set of slipring wires. Measured 4A spike at 7.6V. Slipring was fine, but the current surge was very short – the fine nichrome wire used as an ignitor blows like a fast acting fuse. Ran many shots thru the slipring, but still decided to run separate wires for the gun to prevent damaging the slipring.
