**Exact dimensions.** True size, with no printing tolerance added.

## Notes

- 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.

## Sizes

|---|---|---|
| Location | inboard leading edge near the root | Boldmethod |
| Effect | root stalls first; buffet several knots before stall | Boldmethod |
| Reference build | small wedge on 100 mm chord | illustrative |

## Questions

**Will a stall strip fix a tip-stalling RC wing?**

It makes the root stall first, the same aim as washout (Boldmethod).
