Here's a better photo of the radio and engine area.
Servos are Futaba S-133, servo taped to the coroplast. Rx is an old Royal AM that I built from a kit many years ago. Battery is an 80mah that I built from the cells out of one of those rechargable 9V NiCad batteries. Rx and battery are held in place by Velcro. (Hopefully, the exhaust diverter will stay on so the radio doesn't get drowned in oil.)
