I'm surprised there isn't one available in the states. Here there is and ARF trainer for gas (20-50cc) but I'm sure buying it here (Taiwan) and shipping it would be crazy. But it is made in China and probably available through some of those people that bring in china ARFs in the states (raiden tech, chief). They are great trainers because they are so easy to see and they fly ever so slow, take a lot of punishment and just keep on ticking!
