Aaah, that looks like my old Futaba 6x Super in the trash! I can`t bear to throw it away. But that and my old Skysport 4 are the only old transmitters I have. I recycled the 6x servos into the Tiger 60 I recently completed. I read that the 72Mz computer radios can be upgraded. I`d be more than happy to give it away to someone that could use it.
