I picked up AN6-7A bolts and with the correct grip length the wings were pretty
tight even before tightening.
Also I made progress on the Diehl skins and was able to remove the spars and
ribs today.
I will have to remove the rest of the vinylester now and then the skins will be
good to go.

Thanks Mark,Sid and others for the replies.I feel much more informed and
confident regarding this now.
I guess the only other concern I have is as I mentioned about grip length on
the AN6-5A and threads being inside the Wags. Any need for concern there or
should I just stay with those.

I'm guessing the bellyboard is like the control line models I made out of

Many years ago I did a lot of research on, lift, drag & aerodynamics in general

the lift thing, boy oh boy are there differing opinions on th
Both are correct, one controls the "quality" of the lift e.g. Bernoulli, and
the other is just plain lift from angle of incidence. The both work together

The GP4 that George Pereira flies has a layer of 5.?? OZ cloth covering the
wings, the GP5 that "almost" raced at Reno this year is built the same way,
except it has two layers of cloth over 1/16th inch mahogany 45 degree ply.
It has been clocked at over 435 MPH before the engine blew.

the GP4 calls
for a glass coat. The lateWhitman recomended the glass layer for ply wings
as a protective measure. Didn't the Falco have tapered ply covered wings?

No big deal, but a thought that may be maybe worth expressing.
My concern with pre-fab wing skins (any wing skins) is the quality of
bond with the spars.
We need to remember that the airplane is literally being picked up by
the skin of its wings (well 2/3 of it is). That may not translate to a

top surface of the wing into 1' x 1' squares and screwing a cup hook into

I am concerned about no wing washout at all. The whole purpose of wing washout
is to preserve aileron authority/effectiveness at high angles of attack, and

the tips are not, and ailerons can still be used to co
