well boyz- The early Extra and the EDGE are really about the same design
and you can cogitate the sweep factors till the cows come home
But
th lightest one with the most power will be the best
ther isn't 2 cents worth of difference otherwise.
Size really doe not matter eithe
Having done the 33% series of H9- aerobats- the lightest ones were the best
but I liked the CAP and the EDGE I had because I had the power jacked up in these. (not the weight -the power .) Going down . We redesigned all the flying surface on one EXTRA - thinner n lighter sections -it was same planform but the reduced weights really showed upto IKARUS models -we again saw the same thing in5-6- ounce flyingweights .
40% stuf? again -the same - the light one
27% ?same again
The corker is in full scale aerobatic types
same thing
th best performers have highest power -lowest relative weight
