That looks like a 1/8" shaft. If it is, it's not surprising and it's why most of us run motors with 5mm shafts. Novak should replace that.

I've been thinking hard about doing this Revo conversion, but after having thought about it; I've decided not to do it. I found out today that my Compro is still in limbo and I'm anticipating the esc needing to go back to MGM and once that happens, there's no telling how long it will be before I'm running it. My only choice at this point will be to buy a new esc, if I want to get up and running. After all of this waiting, the excitement and anticipation has worn off and my Muggy is just going to sit. I know that all of this electric conversion stuff is really just experimental, but the buying something and having to hope that it will work has taken its tole. My buddy at my LHS called me today to let me know that he got in a T-Rex450SE Version 2. That's going to cost me a lot less than converting a Revo and I KNOW that it will work and if something breaks or doesn't work right, all it's going to take is a five minute ride to remedy the situation.

I'm sure that I will come back to the world of large scale electric cars/trucks, but I need a break.
