I was refering to the Classic Europa wing. The section has a slight bump just
under the LE which is very easily sanded off. The nose radius is also quite small,
again easy to sand off even with a sheet of fine abrasive round the LE.Accurate
templates are essential and the plans version isn't accurate enough for these subtle
curves. That's what was wrong with G-KWIP's wing. Always dropped L wing in a flaps down
stall.

Interesting to hear that you can fly with a flap down; but for me a lot is going on just after take off, watching the gauges, the speed the VSI, changing prop pitch, unlocking to get the wheel up and pushing the leaver with the right hand etc - maybe the spring/tension is a bit off if its first flight, I am not sure how I would cope if there were to be a sudden roll at that point.
Yep I also value Grahams wisdom and contributions; I am just thinking of the message, unintentionally, its sending to current builders. The fact is hundreds have been made by imperfect amateurs and the stall characteristics are one of the first things explored during the test flights.
