If you mean receiver(rx)? then someone told you wrong,, Tower has the Great planes mini rx for like $25 for parkflyers then you buy the crystal (xtal) for $10 to match your transmitter (tx) you can have as many rx as you want and fly them all from the same tx as long as the xtal matches, however your radio/tx only has I think 6 model memory...but I thought you could use standard servos on a slow stick......Rog
Transmitter is in your hand
Receiver is in you plane working the servos
