I stand corrected. But I just checked a popular entry level model I have and at the wing tip it was smaller then 2mm. But what is the whole point? I have seen models with stall strips on them that certainly would not have passed if measured. It was a rule that long ago quit being relevant if it ever was. There are more rules like that in the book that should get the same boot.
With hindsight it could have been worded better. Maybe the CB could issue an explanation on what it means similar to the Masters Nats qualifying?
Tony's got a point. Having installed stall strips on thick winged sport jobs before to make them do better stuff, their radius was around 2mm or just under.
The rule implies that a "knife edge" wing will hurt more than one with a larger radius when the wing hits you. Absurd.....! It is a silly rule
