Wing area = 257 in2
= 257 x 0.254 x 0.254
= 16.58 dm2
1 oz = 28.349 gram
9.2 oz = 260.8 gram
1 ft = 0.3048 meter (3.048 dm)
1 ft2 = 9.29 dm2
Wing loading = 260/9.29
= 28.06 gram/dm2
AUW = WL x WA
= 28.06 x 16.58
= 465.23 gram ???

Kalo AUW 465 gr sih, pake EDF-55 dg motor 200 Watt dan lipo 3sel aja udah lebih dari cukup powernya
bahkan power loadingnya sangat berlebih, 0,43 Watt/gr

kalo ukuran pesawat gak berubah, maka wingloadingnya jadi 60 gr/dm2
nanti jadi batu terbang itu
