Hi Joe! Just curious, do you have any experience with building r/c airplanes? If so, may I recommend those basic building principles for attaching the wing & fuselage can be applied to control line. For example, assuming you build a profile model, when you build the wing, firmly mount the bellcrank and lead out wires and a suitable length stub (extending about 6 inches past the wing trailing edge or as be fitting) for the elevator pushrod. Build your fuselage sufficiently snug so that the wing can slide into the fuselage fairly snug and secure. At various times, I've successfully used either 10-32 and 8-32 bolts, as needed, from the bottom of the fuselage (through non threaded hardwood blocks), through the wing (non threaded hardwood blocks) and into the upper fuselage (embedded, threaded hardwood blocks). To add a bit more stability, you could add (as I did) a suitably sized triangle shaped balsa fillet to the outboard wing that would act as a stop to prevent the wing from sliding completely through the fuselage and another fillet attached to the fuselage that will minimize the up and down movement of the wing when slid and bolted into position. With the wing in place, I generally use an overlapping length of 4-40 pushrod or music wire (depending on how much flexing I expect and or bracing I want to build into the project) and two suitable sized Dubro wheel collars to join and lock the stub to the elevator horn. I hope my description make sense because it is essentially what I did when I built my great big Pat King Ringmaster Triplane. It is a joy to fly and easy to disassemble for storage and transport. I've also used this same basic technique to build some of my S-1 size Ringmasters with consistent success.
If you're building a full body fuselage, the wing can be built, essentially, just like any r/c model but you will have to decide where to build an access hatch in the fuselage so that the elevator pushrod and stub connection can be accessed when attaching or removing the wing. I did this when I built my replica of Dave Gesieke's Novi III a few years ago and I haven't had a bit of trouble with it to date. Given my pathetic skills, I must say it flies great!! Hope this helps!
Jim
