Default Wing shape issue

Hi, I am building a new Deb spad with a few mods. Mostly its by the availible plans, however when pulling back on the top half of the wing assy [to glue it to the trailing edge] the front leading edge came up on me despite having some weight on it. While the plans suggested that some was ok my wing came up quite a bit. When placed on the fuselage the leading edge is about a half inch off of the surface in the front. [even tho the rear of the wing is mostly flat] This makes it almost semisimetrical. While I think it would fly ok I am concidering cutting into the fuselage [below the square angle] to lay the wing into to lower the angle of attack of the leading edge. Do you think this would weaken the fuselage to a dangerous point? Or would it be just another version of a spad that may work well. I hate to rebuild the wing [it came out so well and strong]. I used the brown 2 1/2 square gutterpipe and some beige wing and tail coro. with thw WWI British colors for the tail and decals. Looks great. I just need your input to continue. Also I tried to keep weight down as building but it came out quite tail heavy. Is this the norm for the Debonair? I hate to add nose weight but the wing is back as far as I dare. It totals at 5lb 6oz. Thanks for your input........................Keith

1/2" is 'some'. Don't worry a bit about it and fly it. It will be fine. You may need to shim the t/e a tad. Fly it first and if it wants to zoom on adding power, add a couple of yard stick shims undet the t/e. I always carry a couple of y.s. shim and some packing tape to the field for field test triming and repairs.

Would cutting into the fuse be a no no?

That would cut down on your fuse strength I agree with shims on the TE. My trainer was the same way. I didn't bother with it and just flew it at about 1/3 throttle.

5 1/2 lbs is good for a deb. So long as the ailerons aren't touching the hor stab, the wing's not too far back. Don't cut the fuse, it weakens it terribly. Add shims, or reflex the trailing edge of the ailerons up if it climbs under power.

If you ever need to make another wing do a search in this forum for "Wing Jig". After you build one your next wing will come out perfect.
