Tricycle Gear Legs and Fairings - Section 46A
Fiberglass and I just don't get along very well. It always feels like I need to make multiple attempts to get it where I believe it will hold up to the rigors of flight & landings. Wheel fairings are just a pain in the butt to get them fitting properly, at the right angle and parallel to the flight stream and the longerons. Also the attachment points seem inadequate without some beefing up IMO. I tried using the marked screw points in the main wheel pants, only to have one end up 1 inch higher than the other. As you can see below, I tried the flox mounting method, but felt it added little strength where the screws attach them to the mounts. So I went back to the method I used on the RV 7 and added 6 layers of 9oz fiber glass cloth in each screw location. This made the fiber glass at least 1/8" thick there and tapered out the glass with peel ply. We put some chalk lines on the floor and then re-installed the them once they were in the right location. It turns out the suggested hole locations were not off by much, but enough to make over a 1" difference at the trailing edge between them.
