i have a Showtime 4D 90 and im just setting it up. i have a JR XP6102 radio and i was wondering if anyone knows how to use 2 separate channels for elevator and 2 for ailerons. i know how to do it for just ailerons but not both. Maybe i shou;d use a Y-harness and just trim them on the ball links manually. ( then i have an extra channel for smoke ) man i wish the 7202 had been out sooner. then i would've got it instead of a 6er.
