Well,
Guess I'm gonna buy a Centax-II for my Impulse. I was running the standard 2 shoe clutch w/o any problems so far with the Novamega SX.12 SE. That engine was also doing well, but in comparison to the Rossi, it is like a joke. Now from what I have found out so far (thanks for the info of Glenn Cauley by the way) the clutch is not good enough for this engine, so gonna get a Centax II.
Ontheroad is driving an HPI RS4 so it's gonna be a piece of cake to kick his ass. There is also another rival, a Mugen MTX3 with a Novarossi NSR12S3.
As I said, good times are ahead! :-)
