Thanks Bud,=0AI use Gurney flaps for trim, a few inches of draft excluder s
tuck under the trailing edge of one aileron. I always tried to get the flap
s reflexed up a bit to match the digital print out of the airfoil. Most fol
ks assume it should be flat under the TE but it isn't. Another omission in 
the manual! Poor old Andy, he was under so much pressure when he wrote it, 
all sorts of things needing attention, especially the hassles they had with
 the fuel tank. No one told them the tank would expand when filled with Mog
as! Took a year to fix that! =0AGraham=0A=0A=0A=0A=0A______________________

=0AWell said.- If a plane comes in here we do the same thing.- It =0Asa
ves a lot of head scratching.- We measure root, (granted outside of the 
=0Afiller and fillets), mid wing between the flap and aileron, and tip.- 
Then =0Acompare the two wing sides.- If you adjust the flap and aileron t
o even =0Athem up (the aileron has to be contoured to stay where you want i

global.net>=0A>=0A>Tony, =0A  I can tell you from experience that both wing
s have to be the same.- I =0A  set my up with the fuselage bottom only.
- I now have both top and bottom =0A  on and have 30 hours of flight time
.- I have a left wing low.- I =0A  went back and measured both wings an
d the right is 2.4 degrees and the left is =0A  1.7 degrees.- =0A>=0A>Not
 sure why!- I took pictures of the level =0A  showing 2.5 degrees on both
 wings!=0A>=0A>I have lower the left wing flap =0A  about a degree or two, 
but at low speed the aircraft left wing drops in a =0A  second.- I'm plan

- If it's right you will have no troubles when you fly it.- Use =0A  a
