The sad loss of Cliff and Betty Shaw has highlighted the Europa's behaviour around the stall.
Similar to 'Wiley E Coyote' , my aircraft G-JULZ had a severe (right) wing drop in the flaps down configuration stall. G-JULZ has an XS fuselage but the original foam wings.
In the early days of flying G-JULZ I noticed that the ailerons were nicely in line with the wings when on the ground but in the air with the wings loaded the ailerons were no longer streamlined with the wing.
In straight and level flight it appeared that the right aileron was slightly drooped. Over several flights I slowly adjusted out the droop at the wing root. The result was the tendency to wing drop had disappeared and G-JULZ now has very benign stall characteristics in all configurations - normal and accellerated.
With the factory stall warner fitted, it was not necessary to fit any stall strips to the wing at all, which keeps the wings aerodynamically clean and permits the maximum short field performance.
Now this is not the solution for all wing drop problems; symmetry of the wings (particularly the foam ones), flap set-up and the actual incidence of the wing to the fuselage all have an effect.
But have a look at the ailerons when the wing is loaded. If you have a wing drop at the stall, it might be part of the problem.
Plainly, adjusting the ailerons to correct a streamlining problem will have an effect on the travel limits of the controls which must be considered.
regards,
Mike
