I have a new 42% Pilot Edge I will be assembling soon; been reading all summer about setups. I too found the recommendations for 3 servos in pull/pull, and two push/pull in the tail. Haven't exactly figured out why, other than the short, direct linkage maybe loses less "power" to the surface. My Pilot edge comes with a plywood servo tray for pull/pull, but I discovered after reading threads on F G that there are push/pull cutouts in the tail. I'm going to be using two Futaba 9157's on my rudder...
