1/8 scale buggy conversion - help please!

I've been wondering what people mean when they say gasket for a Hyper 7/8. Is it the thin red rubber ring that seals it or the blue gaskets for a Jammin or 9.5. I was going to try the rubber seal with the blue gasket, but I have both so I can try it different ways. As far as the drive train goes I can't drive the car at all because the spur hit the chassis just slightly. I'm hoping the gasket is enough that it will fit or I'll have to enlarge the hole in the chassis slightly.

My cogging problem is with everything outside the car. It is very noticeable because I am holding the motor. It seems really weird that it should be as fast as everyone says it will be because my Novak 13.5 feels like more power than the Feigao (except when cogging). Weird.... Anyhow I'm wondering if it will even happen as much on the track. It's only when the rotor is stopped that it does it... I have the drag brake set on the MM so when I let off the throttle the motor stops (with no load), however on the track if I don't come to a complete stop the motor should still be spinning some so I probably won't have the cogging (at least I hope). Between that and some settings on the speed control I hope it goes away.
