I stopped using power panels a long time ago. For the starter I use (2) 6 cell nimh packs for the RC Cars, Glow plug clip"s, I solder tubing to the ends of batteries or use the one that holds a single battery. I use the hand crank fuel pumps. I got tired of the wings on the bigger planes getting in the way of the flight box and having to watch the cords for the glow plug and starter getting in the way of the props. That was the main reason I went cordless. I use fishing tackle boxes for the storage part of the flight box.
Is a person in a factory working on an assembly line a professional?
Buzz.
