I have two older Futaba Attack 4 radios (72Mhz) that are gold stickered from the early 1990s that work fine. I see a lot of new receivers and servos available today and am wondering which Rx's and servos are compatible with my Attack4's?
Also there are many battery packs now available in NiMh as opposed to the NiCads once used. Are they compatible and if so how do you charge these things with the original Futaba C10 chargers since the newer batteries have a far greater Mah capacity??
