These FM crystals are compatible with most popular Futaba transmitters and single conversion receivers.
Futaba crystal sets come with (1) Transmitter and (1) Receiver crystal. Sorry, we cannot sell just the transmitter or just the receiver crystal, they have to be purchased in sets.
Please note that these crystals are NOT Futaba-brand, but are manufactured specifically for Futaba radios/receivers, so there should be no compatibility problems. When you compare prices on these crystal sets, you will enjoy a substantial savings over the standard Futaba-brand crystals!
All Futaba channels are usually in stock and ready to ship immediately.
