SteveM: Being that they didn't give you all the info to start with, you should call and see if you can get their techs to change the shift for free instead of buying different receivers! It's a long shot, lol, but hey you never know! The Am info you gave is new to me though, thanks for the info, I thought you would need the shift changed for Futaba or Hitec if you were on AM also. Well my nephew has FM Futaba equipment, he had the shift changed over and it does work flawlessly, I guess the only drawback is the price of having it done and now he has to stick to Futaba and Hitec components! If he wants to use another brand it would have to be switched back!
