That is an absolute awesome looking truck. By "wont kill my pockets"... about how much is this? Unfortunately there is not a middle costing system on the market right now for a truck your size. There is the MM ESC that can be run with a Feigao 9xl. That will be about $250. Then there are the Neu motors which will run you about $280 - $300, and you will still need to buy a $250 - $300 ESC to run that motor.
See, I dont really know too much about the whole brushless motor thing. I live in a novak world and only recently found that there are better choices. I heard of the Neu motors and dont really know too much about which one I would choose. Same goes for the ESC's I am totally lost in getting upgraded.
