Sizes: see table below
- Stall strips are small wedge-shaped strips on the inboard leading edge; their sharp edge separates the flow early so the root stalls before the tips (Boldmethod).
- That keeps the ailerons working in the early stall and creates buffet several knots before the stall, adding warning (Boldmethod). Washout serves the same purpose (Boldmethod).
- No published sizes were found; fit them by flight test.
