This is a VEX 6-channel radio transmitter on 75mhz paired with a SombraLabs SL-8 programmable receiver. 

The receiver is the highly sought after SL-8 unit that offers the ability to receive on any 72 or 75mhz channel, simply by jumping the signal and ground leads of channel 8 so it can learn the new frequency. These receivers sell for hundreds of dollars alone, IF you can ever find one. 

Move fast! This won't last!
