I have spun several early Classic Europas, during test flying for Permit to
Fly. The Classic can bite, clean the spin may be relatively benign but sev
eral had a vicious wing drop flaps down.Imho it may be due to inaccuracy of
the leading edge of the wing which is critical on Don's excellent airfoil.
We were not given accurate coordinates for the section with the plans but l
ater on they did become available. Sanding the wings to + or - .010"over th
e first 12" of chord does give a much more benign stall.Fitting the now man
datory stall strips also tames the stall.

I've decided to get some aerobatic training just for fun and so have been r
eading the Kershner basic aerobatic manual. The section on spinning talks a
bout the characteristics of some planes to go flat and recovery being depen

design. Does anyone spin the mono outside of UK and have any comment. Whil
e searching for info, I have seen one or two accounts on here of accidental
incipient spin. They have made we think I should make sure my payload (e.g
for permit flight test) is better secured than dumped on the seat if a win
g drop could send me inverted.
I was busy fitting my Smart Ass 3 at the strip the other day when my hangar
neighbour remarked that he dropped a wing and rolled out of the circuit on
base leg in a Brezzer after a 6 hour flight to an unfamiliar strip - lucky
to survive I should think. Easy to do though especially if you are turning
across a stiff breeze.
