Gary, I too didn't relish the prospect of snaking cable guides and wires thru the fuse structure, so that's why I used this arrangement. It's simpler anf doesn't compromise the stick built structure.

For the rudder/ servo wires, I placed then on the left side of the fuse (opposite the engine exhaust) and routed then to the Rx thru a 1/2' hole in the wing center section sheeting.

It's good to hear you're still building kits. It seems that kit builders are a dying breed these days! My winter project will hopefully be a Goldberg 1/4 64" Bucker Jungmann biplane which I plan to power w/ a Saito 150.
