The anhedreal is necessary in the Curare for aerodynamic balance....just use a taller tailwheel strut for ground clearance.

Mike,
I had an old Skyglass Curare back in the 80s and it had a fairly thin airfoil....it was fast and landed fast....heavy too. Thats why Hanno put the flaps/airbrake...to slow that puppy down in the downlines and help with landing. Perhaps the MAN plan was revised to make the plane float better at the expense of a little speed. This is probably a good thing because mine was a handfull at low throttle....no bad stall tendency but came in hot....but boy
could it penetrate the wind.
