All,



Finally, my XS wings are almost complete and I'm psyched to move onto 

the cockpit module. I've marveled at the way the flaps and ailerons 

mate with the wing washout...Ms. Europa is indeed a clean machine...and 

here's the rub: I've noticed that on both wings, outboard of the 

outermost aileron hinge, my ailerons "droop" about 1/16th of an inch 

such that the air flow on the underside will be disturbed at the hinge 

line.  I'm considering adding a short length of hinge to bring the 

bottom of the aileron even with the lower wing skin.



Has anyone else had a similar condition, and if so, was it 

ignored?...or how was it dealt with?

Yes, I have the same problem. One aileron is worse than the other. I noticed it during fitting, tried to make an adjustment, failed. I then added it to my squawk list notebook, to see if like many of my other little squawks, it got fixed or went away by performing later steps in the manual. It didn't. I was all so thinking of adding a little extra hinge.

Fred,

You are a fine  builder, nearly perfect is not good enough. I placed a small 

spacer under the hinge so that the aileron mates exactly with the wing.

Fred

Or you might add an extra ply of BID to make the flange a bit thicker, 

make it stronger too, that area is a bit prone to cracks in the paint 

after some flying.

(I think I understood youir question but can't be certain  )

140 hrs on it now and works fine.

Thanks guys for the input...though this project constantly provokes my 

battles w/ perfectionism, my sense has been that certain things 

(including basic air flow over and under the wings) warrant special 

attention.

A short hinge at the aileron tip will raise the bottom surface of the 

aileron into alignment w/ the bottom surface of the wing. It's great to 

know that solution has worked for others.

Hi! Karel/Fred



I didn't change mine after filling and painting it was negligible.

However as Graham says another layer of bit would be better than a

packing. May as well have the weight of your "fudge" work for you

instead of being a passenger for the life of the a/c !

Regards



And a Merry Christmas and a Happy Health New Year 2007 to all.

Hi Fred,

I also have this problem, but have not yet closed the wings. I have believed 

the problem is a result of the aileron closeout pressing down on the top 

surface of the aileron, because when off the wings the aileron hings flange 

is perfectly straight. With the ailerons mounted, lifting the closeout lets 

the aileron tip rise. If so, I assume the problem will disappear when the 

top skin is bonded on with a spacer between  the aileron and the closeout 

with the aileron held in the correct position. Are your wings closed?



Regards,

Keith Hickling.
