Two Servos on a GP Spacewalker Elevator ??
I put my 2 elev servos sise by side in the regular mounting location (lighter engine) with the pull/pull rudder in between and raised just a little. The trick here was to cross the rods (dave brown glass rods) to get a straight shot. Worked really slick.
I upgraded all hardware to 4-40 to be "legal" for IMAA, I feel sorta silly now, noone else does it and the plane really only needs the supplied gear. I even used high torque servoes, but those are headed to a new home now, and standard servos are going into the SW.
