I was actually going to convert mine with the mamba monster kit and after I got to actually pricing it to do it I backed out. It was going to cost me $400 just to convert it not counting the lipo batteries so it was going to be around $500 to do it. For that price I would just sell it and buy a E Revo. You can't use the two speed tranny anyway and that was the only reason I was going to do it was to have a 2 speed brushless revo. The 2 speed won't hold up to the power of the brushless so you have to lock your tranny into 2nd gear. I know there are people that convert them and prob love it but to me personally it wasn't worth the money not when I cound sell my revo as is for atleast $300 and just put another $300 with it and buy a brand new E Revo.
