I use the roto start. I like it better. Not as bulky as a starter box. Plus alot of people have been having problems turning over there new motors with the bump boxes. Unless they heat the motor up with a hair dryer
Not Roto start[:'(] LOL I think all us Hobby Shops use some form of the Roto start............its to easy to start all my demo's with it and I have a 4500 maH stick that lasts a long time
