Yeh -that's one thought
I looked at the setup I did this way --
I wanted to slow span flow at high AOA- (sorta like the Side Force Generator things)
But I did not want air to pile up at the aileron tip - the shape was my own idea.
So I decided that if I stopped em before the aileron LE- that would be a better compromise.
The plane lost 90 square inches ( and 8" of span) -was 97"- now 89") but no detectable increase in wing loading (weight is 23 lbs ) roll rate really did increase.
Every time I saw off span -I get a better aerobatic setup -but I start with prety low loading planes.
I am just now completing one of the GP CAPS with a Evolution 116 n tuned cans - I can't afford to try the sawed off wings till I see how the plane works first -wing loading is not low --as you know.
Then I saw the Velox setup--almost the same approach-
I don't know if the tips on the Velox were Velox's idea or Peter Besenyie's idea - or whose - anyway I was hoping someone did .
