Futaba X-347 3-Channel Radio Control System. Includes transmitter, 2xreceivers with crystals, 3 servos, switch harness and manual. I have not tested this all, the TX turns on, the servos worked. Thus is best treated as a 'spare' lot, although its all in very good condition. The battery lid is missing off the TX. there is a PCM module in theTX. the RX are PCM.
