A friend who has been awy from the hobby for a long time brought over a Futaba Conquest (FP-4TNL) 4-channel AM radio. It's on channel 56 at 72.910 Mhz. He still has the transmitter, receiver and 4 FP-48 servos. Interestingly the receipt was still in the box showing that he bought the gear in 1988 for $129. The whole set up has exactly 2 flights on it as his plane and his experience with the hobby was short-lived. What if anything would you recommend salvaging and reusing? Is anything compatible with today's gear?
