@aokholm
Can you please share where you got your L and D coefficient values for a KAP foil from?
We scoured the net, asked the manufacturers, did our own pull and angle tests on earlier models…
Nothing of use it seems.
The result for these larger foils came short of what we expected.
Would be great to have more reliable data / method
older examples
