(RV8-QB) Ok ive looked at all the post on the three lower -4 bolt holes. Here is my problem the two lower bolts that go through the lower hinge bracket(vs-410pp) and the wd-409, if I drilled for a -4 there is no way I will have ANY edge clearance. If I were to drill for a -3 I might have 1/16. I checked everything ten times and every other measurement is perfect...................I dont know what to do should ? This is from A pre-punched empennage kit and a QB fuselage. Any help would be appreciated.
