RE: Seagull Extra 300 - 75 assembly thread.
I got started tonite with the ailerons. I wanted to replace the fibre hinges with Robart hinge points. I laid out the locations on the first aileron then moved on to the wing panel. Thats when I realized the trailing edge was not thick enough to support the hinge points, they were only 1/4" thick.
I didn't like the fibre hinges so I upgraded them to Great Planes fibre hinges, they were nearly twice the thickness of the supplied hinges.
Here are some photos of the Robart hinge point instalation if anybody is interested in how to do it.
Two things you must remember. The hinge pin must be in line with the leading edge of the aileron, and the hinge point must be at 90 deg. to the aileron.
When you glue them in put alittle vaseline on the pivot point to keep the epoxy from sticking to it. Also, use 30 min. epoxy to give yourself time to work. Work some epoxy into the hole thenremember to "butter" the hinge before you insert it into the hole.
Needless to say, I did the work for nothing anyway.
I then moved on to cutting the stripes I want to do on the bottom of the wing, need something to make that white wing stand out against the sky.
