I had a Classic Europa that was converted to a Trike.  It handled well, and
stalled straight ahead - provided the ball was in the middle.  I got a bit
lazy once, had the ball out to the left, and sure enough I had a wing drop
(about 80deg in about half a second )- in other words the incipient stage of
a spin.

Standard recovery worked well,( as a reminder:- stick forward to break the
stall, smoothly up to full power, roll wings level.) lost about 300 ft. and
the aircraft recovered immaculatly.  Please also remember the "stall speed"
is only wing level and unaccellerated stall speed.  Wings actually stall due
to the angle of attack !  OK review over - for which I appologise.

In short the stall/ spin is pretty benign, with no nasty habits, HOWEVER, as
you point out these are hombuilt aircraft, and vary greatly from model to
model.  The only way to be sure is to test fly it ( with plenty of altitude,
and a suitably experienced pilot).

BTW what is the registration of the aircraft ur looking at, and what's your
local ?
