yes thats wht their saying i strongly dislike Jr for ther imcompatibility with futaba and Hitec recivers science i dont trust JR recivers. i have had nothing but beihg blown off by the JR tech Support when i tell them in not using their servoes or their equiptemt so thats why i use Futaba if you want a great radio get the New futaba CHP with PPM reciver and 4 servoes for $250 is 10 times better than the JR 6102
