On my biennial renewal flight I was deliberately stalled in a mono gear up steep turn (possibly 60 degrees). The plane went very abruptly into a nose down rapidly rotating spin. No problem correcting with standard recovery. A friend did something similar in his trigear and found himself abruptly in an inverted spin. He let go of everything whilst trying to think what to do and the spin corrected itself. The moral for me is think carefully before trying these moves and certainly give yourself lots of height.

David…your cautionary note is much appreciated…Fred

Agreed! Training, proficiency, and altitude are all prerequisites imho. 
That said, the Europa design has great recovery attributes, so testing ‘should’ be benign. I have never yet heard of a pirep of Europa recovery issues over my 25years of following Smile …. Even with the long wings (!) per recent reports (?). But keep those pireps coming!
IMHO spins are a fun and benign maneuver in a capable design. Not so in my unrecoverable (blanked rudder) lil’hummelbird - not the best aero design but still more fun than a barrel full of monkeys Smile
With a significant aileron trim tab required on my classic, i am typically expecting a right hand break. Centered ball power off stalls so far in my 200hrs with it have been pretty normal requiring only moderate foot exercise. My new CYA100 AOA is performing great, although id like explore how the vane and indication perform in full slips near the stall left and right. Thus my original question.
Having it recover from an inverted spin by letting everything go is a neat trick! and again supports the excellent design hypothesis.
Cheers,
PeteZ
