SMT-10 is my choice. Dont go wild on the power and you are set. I currently run a 17t Radon brushed motor, an XL5 on 2s and it has plenty of go. Next on my list is a proper servo(running the stock TSX45 and its hurting).

If you want wild power then go with the Kyosho. The current Mad Crusher has a great looking body and really only needs some Clod tires to look the part.
