In building my SR-2500 wing, and following (I think) the directions in the
manual, I found a very disturbing thing. And it seems to me rather
dangerous!
I don't know if the Rebel uses the same design -- a "U-chanal" along the
bottom edge of the main spar in the area of the lift strut fittings and a
external doubler on the leading edge and wing skins.
After riveting the bottom tank skin, bottom wing skin and leading edge skins
to the main spar (with RR-6403 tank rivets in the tank area and RV-1410
rivets
elsewhere), as directed, I have turned the wing over. I then removed the
top
tank and top wing skins. I found a very disturbing and, I believe, a
dangerous situation. The RV-1410 in the main spar that go through the W-544
doubler, leading edge skin, wing skin, main spar flange, and the W-526 spar
chanal are far too short - not even protruding from the W-526 chanal!
Since this chanal (W-526) is in the location of the lift strut attach
fittings, which would carry a main load, I believe this to be a major
problem!
Please comment if this a known problem.
Also, I ordered and used some of the brushable pro-seal from Levens Aviation
in Toronto that was mentioned a week or so ago. While it seems too thin to
use on a verticle surface (it will tend to run), I have used it as a second
coat on all joints and really like it
