Back to my original question: How many are out there? Bad behavior?

The original Schueman and my bird + the FJ-1 were complete make-overs, there must be another 8 or 10 H-301,s with the leading edge mod and flap travel change.

Don't know any bad habits, the low horizontal will shake about 3 knots above stall because it is eating dirty air coming off the wing..........this has saved me a couple of times.

The gear is weak by todays standards and so is the aft fuselage. Try not to ground-loop her or you will be visiting the sailplane doctor. Keep her dry because she has wooden bones.
Enjoy,
JJ
