YES and NO, the transmitter module is tuned for what ever frequency it's on, it is illegal to change the crystal in a module,you can however put in any channel module you like as long as it on the right band. if you don't have a module you need to send in the transmitter to futaba and have it tuned for what ever frequency you want too switch to. futaba receivers are tuned into high and low band groups, if the receiver is low range you can only use crystals from 11 to 30 in that receiver according to futaba... if you put a low band crystal into a high band receiver or vice versa it will not be tuned to optimum performance and could cost you a plane.
