Normal or cruise mode: the trailing edge of the wing (ailerons/flaps) are in line with the wing’s aerofoil section.

Reflex: the ailerons/flaps are moved upwards by usually a small amount (1 to 2mm)) to change the wing’s section to make it fly faster. Most glider aerofoils have undercambered sections to provide good lift, but can be made faster in flight by using reflex mode which essentially removes the undercamber altogether.

Thermal/climb mode: the ailerons/flaps are lowered slightly to increase the undercamber, creating a ‘liftier’ wing section.

Snap flap: the ailerons/flaps move in opposition to the elevator. Up elevator = down wing trailing edge and vice versa.

Hope this helps! Cheers
It helped a lot! Thank you!

Get yourself a foamie, then fly it to death!
Its been many years since I was out on the slope. But I am not new to it. I started with thermal ships. I think it was an Oly 100.
The best day I recall on the slope was 50 mph steady, leaning into the wind so hard that if it had suddenly stopped I would have tumbled down the hill.
That was flying a Jaguar. I WILL be flying other models I have before the Stormbird goes up. Thanks, Ole slope.

Welcome back!
Thanks! I try to write my questions to sound as though I know nothing, that way I get the most info!
It isn't meant to be deceptive.
