RE: Great Planes Reactor GP/EP 3D ARF .46-.70
Pull-Pull setup:
I set up a Pull-Pull rudder system using Dubro PP horns, but with a Sullivan Kevalar lines and clevises (#521). I placed the Hitec analog coreless 985MG servo on the bottom of the fuselage kinda under fuse's widest point of the orange side stripe. The lines just run outside the fuselage and angle up to the tail horns. I did not need any lead to balance everything. My biggest concern is that servo gets oily during each flight. I wipe it as clean as possible each time.
I'm using a Saito .82, 14x4 APC, Hitec digitals 5626MG on everythng except the Rudder. Power everything with a 1800 MAH NM battery.
