A stop at a local hobby shop brought me to this radio. The Spektrum DX5e has just enough features to allow me to control this thing remotely to test the chassis. It's a digital 2.4 GHz radio, but without any of the fancy features that would have driven the cost way up. The Sabertooth motor controller I mentioned several posts back will connect nicely to the included receiver. In addition, the Sabertooth has a BEC which will power the receiver off my main batteries. One more thing checked off my shopping list!
