If the factory team kit for the RC10 is like the RC18 one (which I believe it is) I would personally start from zero and build from the ground up based on the kit, you'll spend some extra money, but you'll get the top of the line stuff. There's no sense in putting together a sweet truck and using your stock engine in it, it'd be kinda like building a Corvette chassis and only putting a Vega engine in it

besides, I believe the team kit is everything except engine and radio... not really an upgrade, more like a replacement..

do'oh!!! I just talked myself into going out and buying a team kit
