REFLECTOR: 4th test flight - roll tendency persists

Guys,

I went on my fourth test flight this afternoon.  Still have butterflies
before the flight and check things over like I have OCD (yes, the canard
bolts are still there, for the fourth time...).

Dealing with a few issues now that I've left the pattern and brought it up
to speed.  I noticed on the third flight that it wants to roll to the left.
 This is not a yaw (ball's in the center), but a definite roll that
requires right pressure on the stick to fly level at 140kts (more pressure
for higher speed).  Aileron trim isn't enough to take it out.  On that
third flight, when I was flying level at 140ks by using right stick
pressure, when I looked back I could see that the trailing edges of both
ailerons were a little higher than the wing.  So, before the fourth flight,
I drooped both down so they were ~1/8" below the wing (they were level
before at rest), but this did not have much effect on the roll tendency
(although the ailerons were level or drooping at speed).  It definitely
seems to be an aileron issue.  When I'm flying level (using right stick
pressure), the ailerons seem to be in an equal position.  Letting the stick
go, the right aileron comes up, left down and it rolls.  Any other ideas on
things to check?

Slow flight went very well, nice control down to 60kts.  Easy 180 turn,
then back the other way holding altitude.
