I've slowly been working my way up the glider food chain (foamie, built up,
composite, etc..) and now have a couple of planes which I need
help/suggestions setting up. One is an electric Graupner Cumulus 2000,
which has ailerons/v-tail, the other is a Flamingo HLG which has full
Camber is VERY useful for getting more lift on light
days. Works better on some airfoils than others.
Its never more than 3-5 degrees to be really effective.
1/8 is probably too much for a lot of cases. I'd say
you get most of your benefit in the 0-3/32 region,
but it probably depends on the

Isn't flat and energy-effiiceint kind of any oxy-moron? The former implies some

The sinking speed in a turn = straight line sinking
