I have to make some questions (perhaps silly for someone).
Which is the best engine, 18ss - G3.0 - OS CV-RX?
I have tried to find specifications but I was confused [

].
Now I own the T-15 engine with rotostart. Will I be able to use the roto start with one of these engines?What I mean is If I can adjust the back plate in order to use the same roto start?
Thank you.
The OS .18 CV-RX is definitely a much better quality motor than the HPI motors. You cannot use the T-15 rotostart with the OS motor. But the pullstart is a great way to go because you don't have to deal with the problems that come with the rotostart when parts break.
