making some progress with this build at last. Enjoying the kit so far, everything was going very sweetly until I tested the fit of the main wing assembly and the fuselage.
There was a huge gap, got to fill it with styrene card. Other than that all is good.
If its not to late, have you tried to see if you can get the fuselage to come out to meet the wing instead. I seem to recall that the sides of the fuselage should go strait up, so if the are 'leaning' it might be there that the problem lies.
