We had the same problem with our ES. The plane wanted to
roll to the right and the force on the stick to overcome the roll
increased significantly with speed. We also changed the incidence and
solved the roll problem. We did our stall testing prior to correcting
the wing incidence. If I remember correctly we stalled the airplane by
maintaining altitude and slowly reducing power until the airspeed
decreased to the stall speed. We tried no flap to full flap and the
numbers corresponded to the Lancair figures. We kept the wings level
entering the stall and there was no roll tendency at all. I was with an
instructor that has over 10000 hours and he did not comment that the
airplane performed different than he expected. Between myself and Jeff
we did over 20 stalls and in all cases the stall came gently and it was
very noticeable on the stick pressure when it was starting. We do not
have stall strips, stall warning, or an AOA system installed. We do
however have two airspeed indications. My opinion is that the type of
flying that you do with an ES does not require an AOA system. It is
clearly designed to be a great cross country machine and that's it. We
fly it that way and maintain the proper airspeeds.
