Do you have to use the glow ignitor if you have the Roto-Tech Starter? Also, for everyone that has one how good does it work? Is it worth buying?

Yes, you still need the glow igniter, the roto is VERY well worth it!! just dont install it on the NX76 motor untill you have at least three tanks thru it due to the very high compression of the motor. you will damage it if you dont wait.

yeah, I broke my friends rotostart after about 7 tanks...compression is very high in the beginning.

Almost forgot...I got the rotostart that has 2 motors. The 1 motor version broke on me twice.

I bought it for my Nemesis and it was a great investment. No more blisters.
