Futaba Propo Set Transmitter: Megatech T3PDF (FM40Mhz) Receiver: FP-R113F (FM40Mhz) Crystal: 67 Servo: Sanwa SRM-102 (Bonus) All used items The transmitter and receiver are vintage items that I kept as backups, so I haven't used them much. However, I bought them used originally, so they show some signs of wear. Since it's FM, the sensitivity is good and the operability is better than AM, so it can still be used without any problems. The servo was attached to a used chassis, and one of the ears is missing, so it's just a bonus. All items have been tested and confirmed to be working. There are two 67 crystals for the receiver. These are old items and are used, so please understand this before purchasing.
