Photo #1 shows the forward edge of the seat pan attached to the spar tunnel. If you seat pan cutouts look different, that's becaus mine are larger than they need to be. I made a measuring mistake so cut the holes too close to the front edge. Didn't look like it would cause any problems so I left it.
- Photo #2 shows the flap detent angle. It is attached to the TWO vertical angles on the fuselage side. The plans show riveting it to BOTH angles, but the rear angle does not get installed until AFTER the wing is installed and rigged, so I only riveted the assembly to the front angle.
- I could not get any riveting tool into that space, so I simply unscrewed the detent angle from the attach angles, set the rivets, then re-screwed together the angles.
