Wayne, you say to Peter to add corner gusset on each end rib, top and
bottom... I have just finish mines as per mam
instructions, there are gusset at each end but just on top(or on bottom if
my memory fail...), should I add some?

Too add...when you get your alum off, make sure there are corner gussets
on
each end rib (top and bottom) between the rib and the main spar where the
"D" skin overlaps (if you have the manuals take a look at the parts
diagram
and you'll see what I mean). These make sure everything stays square and
may
not be there since the alum cover was doing this job nicely. Also before
covering make sure you roll the edges down on the "D" skin and all ribs
for
a nice fabric finish and less chance of the edges chafing though the
fabric.

Probably as smart a move as any. Make sure you follow the (Stit's)
Polyfiber
system from start to finish, with no magic potion short cuts. Or
Ceconite
start to finish (but I hear Polyfiber bought out the STC for Ceconite so
maybe not available anymore--don't know). Seen to many times where
someone
that is supposed to be a "professional" has used some magic concoction
on
fabric "that is better" (in their mind only) than using the poly
brush/polyspray base coats and the proper matching paint over top. Still
lots of AME's both sides of the borders that like to use half the poly
fibers system and then start shooting dope on it (that makes it continue
to
shrink after it shouldn't be). I'm sure if Steve Wittman had another
chance
he would have followed the system start to finish :o(!

At least there's one good thing about all this....you at least already
have
your airplane apart for a good going through. We could have thrown these
things at you after you had it all back together again!

Once you have the alum off you are looking at approx 24 hours of work to
glue and cover with fabric, shrink (don't tell your wife what you are
doing
with her iron!), poly brush and the two or three coats of poly spray if
my
memory serves me right. If you've never done fabric before, see if
someone
local has a copy of the polyfiber video to view before you start. If not
try
to track one down or even buy it with your supplies and when done with
it
donate it to a local RAA chapter or resell it on Ebay!

Thanks Wayne you are a real wealth of info. I'm sure everyone here
appreciates your help.

Bob suggested that I just remove the metal and cover with stits
fabric.
I think I would prefer to go lighter than heavier specially with your
comment on how much nicer it flies with the fabric flapperons.

Thanks again,

Peter

No you're fine Jean!!! I'm getting older and have inhaled tooooo much alum
dust. Top or bottom is fine as long as you have a set on each flaperon to
keep them square.
