Hello,

We have several of these planes at our field being used for training purposes. I have flown all of them in all configurations...speed brakes on/off, AFS on/off, and NACA anti-stall tips on/off. All but one plane flew about the same when configured the same, but one of them was just terrible in any and all set-ups.

I brought it home and checked it out for the owner and discovered it had 1.5 degrees of negative incidence on the wing with the horizontal stabilizer level. The wing saddle was modified to correct the issue with great results. The plane now flys 100% better.
