I have already gutted the electronics, and I plan on getting the Sabertooth 2x10 R/C for the driving, and an ANT 150 for the turret and gun, (thanks to Richard L. for the tip). Also, I figure on having a safety switch on the transmitter to disable the gun circuit in the event of a malfuction.

I was going to use a Hitec Laser 6 for a radio, but maybe the Spektrum may be a better choice.
