I've used both on my rc10gt and can say the roto start is better. With my pull start, I would have to warm up the engine before it would turn over easy. Very annoying when your out in a field. I dont mind having to carry a small cordless drill with me and since the battery will last quite a few days, no problem. You gotta remember that your only using the drill for maybe a minute at most and I dont let my truck die unless for some specific reason or going home. If your engine turns over really easy with a pull start thats fine but mine didnt and I hated having to put the body back on and off whenever the engine died.
