Ok I am building a TopFlight Nobler as my 2nd kit and I just noticed something. After finishing the wings I noticed that I should have opened up the space where the ribs join the spars to get the proper fit. What I am wondering is should I join the wings as they are with the trailing edges not flat (with about 3\4 inch under each wing tip) or should I make a wedge for the root rib of 1\2 inch to make the trailing flat. See attached picture.

Thanks

there is only one way to correct your situation. cut each trailing rib loose at the rear of the center spar, recut the end square with bottom , add a tapered filler,if required and start glueing again. its all part of the building expereince. we all have made similar BOO-BOO's, am still screwing up, in a hurry at 80+ years young. dick

Thanks for the info. How bad would it be if the trailing edges are slanted forward a little? The wing itself is flat and straight. It just that the flaps and alerons would take a little sanding to get a good fit.
