I have a question about the blade cp's transmitter and reciever.I just bought a new body kit with retracts.The transmitter clames to be a 6channel along with the reciever but there are no other switches to activate the retracts.The reciever is a 4-1 control unit.How can I make this work with the retracts? This is a E-flite Blade CP and the body is airwolf with retracts> Please help.
