RE: 6c or 7c or 9c somebody enlighten me
I bought the Futaba 6EXA when i started out. I'm now on my third plane, an Extra 330, which i set up with dual elevator servo's and dual aileron servo's. The 6EXA will not do split elevators without the use of a reversing y-harness. It also will not do split ailerons without loosing some throw. Throws for ailerons when running dual servos are cut to 60% travel up and 40% travel down to allow for additional movement from the flaps knob, frustrating. Also no expo or dual rate for rudder.
Personally i would bite the bullet and get the 9C, has everything you'll need for a long time to come.
