I no longer need this transmitter since I have a MPX P4000. It was used for all my full house gliders for several years. It has the 8 model memory and a spare battery pack. It comes with a PCM receiver and charger. Radio and receiver on channel 46. This radio will do all that the newer 7 and 8 channel radios do and then some. All for just $ 350 including shipping and manual. Fred McClung Albuquerque NM RCSE-List facilities provided by Model Airplane News. Send "subscribe" and "unsubscribe" requests to [EMAIL PROTECTED]
