Darcy:

All 3 fly superbly. So much so, I am thinking about adding dethermalizers to keep them from flying away. All three have excellent weight-to-wing area ratios(below .3 grams/sq. in.) with the largest the best at .28 grams/sq. in. From smallest to largest, the wingspans are 10 in., 20 in. and 36 in., with weights of 10 grams, 24 grams and 50.8 grams respectively.

Once again, well done!
