My new friend Dinkar in India sent some more pictures. He’s trying different materials to see what happens. I think this is very constructive since the children will learn to be resourceful. Actually I think this will work if it’s cut much thinner. It may need a spar for the wing.

Today i used thermo col wings to reduce weight of squirrel,but it

nearest town.We all eagerly waiting for parcel.
