U Can Do 3D
As per my usual, I've made my agonizing descision on how to route the antenae from the receiver. I internally ran the antenae the full length of the fuselage and on the sloped portion of the fuse near the tail wheel mount I drilled a hole and ran a 2 inch piece of fuel tubing down the hole. I snaked the antenae through the fuel tubing. There was a few inches of antenae that extends out to about the rudder hinge.
I still need to trim the tube and secure it, but I think it will work OK. I'll do a really good range check to make sure. I don't have anything that should interfere. I'm running the 2 elev servos on 2 seperate channels on my 9C.
