Tower hobbies seems to only sell starter boxes that have around 750 single motor or dual 550. There might be 1 or 2 exceptions. However, i only need this starter box for the new car im going to add to my garage this summer (1/10 Team magic g4s on road w/ .12 engine), so 750 seems like a good size motor, but please correct me if i am wrong, i have never had a starter box. I also hope it will work with my mt2 as well because then i will only need to carry 1 starter.

is this the starter u have with some sticker on it http://www2.towerhobbies.com/cgi-bin...?&I=LXCUC2&P=0

will it affect the engine, if i have too powerful of a starter box
