ORIGINAL: N2EC I am building a pattern airplane designed to have plug in wings. The airplane will have foam wings and a balsa fuselage to start with and later on I plan to mold the fuselage. The design also shall have a plug in tailplanes. Could somebody please refer me to some article and/or step by step guide on how to install wing tubes in foam wings and attach the same to the fuselage maintaining proper incidence. Also, how would I do that for the tailplane.

Im having to dig deep in the ancient PTX Vector archives but here goes. When it comes to boring the cores to accept the spar socket tubes, I came up with this drilling jig. Worked very well. Any incidence in the wings is set by the tip templates. Same idea for the stab plug-in system. I used Gator tubes & sockets at the time.
