Wing Saddle Fit

Problem/Question: When mounting the wing to the fuselage of a VMAR model, the wooden dowels in the wing key into the receiving holes in the fuselage former OK but when I try to push the wing onto the wing saddle, there is considerable resistance and back pressure. I can't easily seat the wing at the back edge and it almost appears as if the wing saddle is the wrong shape for this wing. What causes this and what should I do?

Solution/Answer: This is quite easy to put right. In some cases the dowels in the wing or the holes in the fuselage are not lined up quite right or the holes in the fuselage former are a bit too low. The wing saddle will be the correct shape, but some adjusting of the holes in the fuselage former is needed in order to better seat the wing.

First things first... DO NOT modify or reposition the dowels in the wing. Instead, modify the holes in the fuselage former slightly by elongating the holes higher towards the top of the fuselage. Do the adjustments in small steps with frequent tests. Use a small round file. You will gradually elongate the holes into more of an elliptical shape (egg shaped). After each small adjustment, test the the wing fit again. You will find that it will be easier to press the rear of the wing towards the saddle as you make the adjustments. When the wing seats properly in the saddle, you are done. Remember, it is easy to do BUT do it in small steps rather than all at once.
