"In the us it is illegal to change the transmitter channel unless you have a module type radio"

well... you learn something every day. in the uk you can just change the transmitter crystal like you can the reciever. not being able to do this would be a real pain if you wanted to fly 2 different frequencies... like you have to at our club if you want to fly planes and helicopters, as they're on different fields. i'd have splash out on one of those fancy synthesised frequency modules... spose at least i'd have an excuse to buy a new gadget.
