Serge, The next time you approach your KR from the front look at the wings from root to tip. You should notice that the angle of attack at the tip is less than at the root by three degrees. It doesn't sound like much but it is very noticable. More technically, when built to plans, with the fuselage level, the chord line of the wing center section ribs should be at 3 1/2 degrees and the 36 inch tip rib chord line should be at 1/2 degree. This causes the inboard area of the wing to stall before the outboard section stalls and helps to maintain aileron control through the stall. Many builders think the 3 1/2 degrees A of A is excessive as well as the 3 degrees washout and have built their KR's with less. They ALL seem to get off the ground, get to where they are going, and land safely. Larry Flesner
