I have seen and tried many methods for power distribution. Everything from stand alone boards, frames with built-in copper, soldering ESCs directly together, harnesses, copper rings…
Most of these were bulky, ran the risk of exposed pads or didn’t make it easy to swap out an ESC.
So I thought up a new method (new to me, maybe someone else does this too). It is fairly simple, just solder together some bullet connectors and heatshrink it all together.
I have done this on 2 quads and started on one for my hexa. All are working great. I use these bullets almost exclusively now:
Also makes this method easier as each end is cut in 1/2.
