Skip the EXA and go with a 7Cap, Eclipse, or Optic. It has limitations in the wierdest of places ... i.e. no dual-servo setup on elevator.
Perhaps this is because only a VERY small percentage of R/C Flyers will ever use dual servos on an elevator, and if they do, they can just use a y-connector. Anyone with a plane that actually needs dual servos is probably way past buying an ENTRY level computer radio. The 6EXA is an entry level computer radio. It doesn't have all the bells and whistles of radios costing hundreds more.
