I remember some builders recommending to make the hole larger than specified by VANs in page 23-05. The rationale being that it's easier to enlarge the hole while you are first cutting it than when the skin is on the fuselage. Currently the hole I have is 0.97 inch. Could anyone tell me how much larger I should go? (I have 1.17 inch in mind from a builder's site)

Hi Jean-Pierre,

To use the left wing as an example, I cut the front side back flush with the cross bulkhead and took 1/8 inch of of the back side of the opening. Did the reverse on the right side, and it is still tight requiring very straight movement to insert the wing.

Best regards,
Vern
