Steady 43 knots straight and level / full negative flap. In spite of Anthony's comment it was in fact a "touch" of rudder, not a "bootful". With my weight and a parachute I would have been a little way forward of the rear limit. At 45 knots the same process had no outcome. I was a bit surprised by the difference in response. There is a bit of variety from one Ventus to another, both from the works and due to aftermarket modifications. This particular aircraft has since had decent fillets applied to the wing/fuse junction and thermals considerably better with the mod. It would be interesting to see if it has had any effect on the spin entry.
