Hi again guys,
My ZERO is the 42-50CC size. I used the US-41 because I didn't want to buy another engine. I have four of these engines and one is in a bipe that weighs 22 lbs. and flies it satisfactory. I am hoping for scale speeds not a hot rod. Sorry at this time I can't post pictures. I don't have the savvy. I used the ply board in the fuse and just doubled where the servo screws are put in. The rudder servo is in the center with a giant double arm that has the rudder on the outside and the tail wheel on the inside. I crossed both wires coming from the tail. The cut outs for the evevator rods are on the bottom of the fuse and can't be seen. The rudder wires come in the same spot as on the original hook up. The two elevator servos are mounted on the outside of the fuse board nest to the fiberglass with the long arms facing to center. I used carbon fiber rods with 4-40 ends and is seems to be OK. I mounted the engine servo (mini) on the firewall. Hope this helps a little bit.
Geo.
