Finally figured out the center of the wing's construction.  With the wing pinned down and the wingtips raised 3/4" gave the inner portion of the panel a 3/4" dihedral then the center was joined with the inner dihedral breaks in the L.E. & T.E. at 2.75" apart.  I then constructed the wing center section in the air.  That was the only thing I could make of the directions.  There may be another way but that will have to wait till next time.

Still have to finish the scoops on the bottom of the wing. 

Here's some pictures of the wing center section and the second mockup with the wing saddle finished and wing leveled.

The stab construction is similar on all of Drela's (scale) models - seemingly VERY delicate!  I had to rebuild the stab of my RIVETS twice (the second was modified a tiny bit)!  The first one got three (IIRC) covering attempts - all potato chips - before I re-built.

Unfortunately, the thread where I had the complete build of my RIVETS, with ALL of the gory details, was on the SFA site in the RACER cook-up.  I did post quite a bit of the build on my (almost) clone thread on HPA (click HERE) so it might have the details.

The second stab is more than two years old and still flat (but needs re-attachment to the fin).  I made it from carefully selected 0.8mm x 1.5mm strip balsa.

Did you laminate the stab tips, Tom?  Wood selection for these very small parts is critical, even with hobby shop wood, and done with a form.  Pins will always leave an indentation that is nearly impossible to sand out without compromising the structure (most noticeable on two-strip lams).  Use wood bits as holders with a cello-tape face (or a good rub with candle wax) to prevent sticking.  Refrain from using the etched "Magic" type cello-tapes!  As the name implies, they are etched and WILL stick.

Found my RIVETS build photos...  the first one shows the original, plan construction, and the second, my modification.  It turned out at the same weight as the first one.  The added diagonals are from 0.8mm square.

WHOA!, I have not seen a stab as you have built this one. Let me know how it does.

I have been told that the F4u Corsair is hard to trim. Can anyone confirm this, and if so, advise on how to mitigate the problem?  Thanks.

Nice start on the Corsair, Tom!  It would have been nice to see some shots of the Rutango in the air .

Tom, you've got to slow down or swmbo will not let you store any more airplanes in the garage, house, storage shed, attic, barn, car trunk. Get the picture , you are FOCUSED and DRIVEN when it comes to building. after work I get to set down at the work area take a few breaths and start a slow session of building and enjoy my videos while working.

I only wish that I had the talent you possess and speed in making sheet balsa magically turn into a thing of beauty.

Some eye candy for those who love the F4U Corsair.

SS, thanks for the link it was a joy to visit the site and drool over the items offered.
