Here’s another stretched Squirrel picture from George in BC, Canada.

It’s interesting to see the different ways people experiment with the design parameters.

Darcy:

The first has a 4 in. chord and an 18 in. span. The prop is undersized –

6 in., and will be replaced with a 7.5 in. prop. Total weight 14 grams, for an excellent wing loading of .19 grams/sq. in. With two loops of 1/8 rubber it goes like a scalded cat, nearly vertically,

the too-small prop churning furiously. The second plane, the Giant

Squirrel, has a 36 in. span with a 4 in. chord. Total weight – 36 grams, for a very good .25 grams/sq. in. wing loading. It flies fairly well with a 9.5 in. prop, but I am going to substitute an 11 in. prop for better performance. This one is definitely for calm air flying as the wing is prone to flexing in windy conditions.
