I'm betting you like the Novak alot better. If not, You could get the new tuning rotor when it's available. http://www.shopatron.com/product/par...56.35129.0.0.0 I am curious how good that esc does. I run a 4.5 with a Quark 80b in my Slato. It has no problems except a little cogging on start up, which I would like to remedy, and have thought about trying one of the SSB's.
