Wing Test Fit

MVC-007S

With the right wing structure completed, it was time to fit it to the fuselage and check for spar and fuse fitting alignment and see how the bird cage of the fuse lined up with the wing root profile.  This was also the first time I could actually see how the all the plumbing terminations (fuel ports, fuel vent line, and fuel site gauge ports) fit between the bird cage structure.  With the wing in position I could also finish weld the upper pulley entry mount for the wing and evaluate where the aileron cross over balance line fairleads run through the upper head area of the cockpit. Because I was adapting a Northstar wing to a Wag Aero 2+2 Fuselage I knew there would be issues for locations of these aforementioned items but luckily I really had only one problem and that was the aileron balance line fairleads on the fuse that did not line up with the fairleads on the the Northstar wing.  I got the torch out and burned the paint off the proposed affected weld area and welded new 4130 fairlead barrels to line up with the wing. Instead of removing the old fairleads I adapted them as a crossover visor bracket.

It was also at this time I needed to make a small temporary addition on my pole barn so I could attach both wings at the same time. The photo above is when I had only enough space to attach one wing at a time. I had the wings on and off the fuselage a few different times as it was necessary to design how the flaps would function and how to trim out the wing root with the side of the fuselage.  The Northstar wing has flaps and the Wag Aero plans only used spoilers, thus I was on my own to design the pulley and cable locations between a Johnson flap bar between the seats to transit the underside of the fuselage and activate the raising and lowering of the flap system. I left the wing struts off during this process and used a temporoary brace to hold up the wings in order to expedite the design of the flap system.
