Assuming the wing area is supposed to be in Meters squared and an asw-22 BL at 26.5 meter span having 16.3 meters squared wing area
Assuming the scale factor of 3.5
Assuming the finish weight is in kg
I get 16kg or 35 lbs for a max weight.
At 14.28 ft sguared that's a 39oz/ft sq wing loading at max weight.
If my assumptions above are right, that ship ought to scream when fully ballasted up, if you can climb.
I'm building the stretched ASW22 DB
(28 meter) version so I get a bit more area. All of the XFLR polars are calculated at 10 and 15 kg AUW.
