Hi All,

Thanks for all of the suggestions! Here is some follow-up:
[ul][*] Autopilot, wing droops and speed brakes - I am not using the AFS, wing droops or speed brakes[*] wing alignment to fuselage, alignment of rudder with vertical fin - I blocked the plan up as recommended and checked the wing alignment - its right at 90 degrees to the fuselage. I also rechecked the horizontal stab alignment while the fuselage was blocked up and I found that the right side of the horizontal stab was actually drooping a little less than a 1/4" lower than the left side. Previously, I had checked this when the plane was on its wheels and did not notice the difference. The offset was caused by an un-level cut in the fuselage for the horizontal stab slot. Anyways, with some light sanding and some minor shimming I have evened out the stab. I also rechecked the vertical stab/rudder alignment and it appeared to be a perfect 90 degree angle to the horizontal stab. I'm not sure if such a small difference would have caused the right wing to drop so sharply?[*] I rechecked the balance of the plane from left to right. This time I had a helper with me which makes things easier. The right wing would hang ever so slightly lower than the left. I added about 3/8 oz of lead to the left wing tip and it evened out perfectly. I'm not sure if such a slight imperfection would have a large impact on the right wing dropping so sharply?[*] aileron differential and linkages - Both the left and right ailerons have the recommended throws and differential setup of 1/2" up and 3/8" down.[*] servo slipping - I have verified that the servos are not slipping.

Do you all think it's possible that the combination of the slightly uneven horizontal stab and the slight weight imbalance could cause the right wing to drop so sharply? The imperfections seem quite minor to me, but maybe?

As soon as I can get out to the field (maybe tomorrow) - I'll test her out with all of the trims reset. If the wing continues to drop, I'll then try trimming with the rudder only and see what happens. I'll keep ya posted on my results.

Again, Thanks soo much for all of the help!
