Hi all im going to be buying a rock crawler ,i need at least 6 channels and i own a futaba 4pk will anyone know what reciever will work with it thankyou (i was looking at there website can i use the recievers used in planes?)

Sorry, but the 4PK is just a 4 channel controller..... You're going to need a different tx like a 6EX to run 6 channels.
