will a 604 reciever work with a 3pk
 

Before I get jumped on I posted this in the radio section with no response so my sons 603fs receiver went out and would like to know if my 604 from my 4pk will bind to the 3pk
Thx

I would say yes as long as they are both fasst radios but it also never hurts to just try and bind it anyway

That's the problem I tried to bind them and am not sure I am doing it right can't find my 4pk manual but in the 3pk manual can not find where it says how to bind the receiver
