... for a low-wing monoplane such as the KR, a starting point would be to use 18% and 34% of MAC. For a wing with a 48" MAC, that is roughly 8-1/2" to 16-1/2" aft of leading edge .....
+++++++++++++++++++++++ Some interesting points from some of the more recent emails I decided to work out the mean wing cord taking the taper into account. These are based on the numbers on RR site for KR2S, 23ft wing span 82sqft wing area Wing area/wing span 82/23 = 3.56ft X 12 = 42.7 inches Using the 18% / 34% rule of thumb 42.7 X 18% = 7.7 inches 42.7 X 34% = 14.5 inches I thought that it was interesting that these figers are very close to what the guys with flying KRs are saying, 8 to 14 inches. Just some ideas to think about. Karl
