Stolspeed VGs installed on a Lambada

I applied VGs on 1/3 of the wing, starting from the tips, so that they cover the front of the aileron area only.

The result: the stall speed without flaps – the one needed for thermal flying – dropped down from 85 to 75 km/h. And the grip in tight turns at low speed seems to be much better. Full flaps landing touchdown remains the same: 63 km/h. But I don’t put VGs on the entire wing length to avoid more nose-up landing – the tail on this beauty is long and close to the ground.

VGs do work again, it’s just a different application.
