Hi Karl,
We have not spun our plane with long wings, that was another participant to this
thread.

Hi Terry,
This is the first note I have seen about spinning the motorglider. Could you
give
us details please about recovery and height loss per rotation ? I have been
unable to stall mine in level or descending flight and I have been reluctant
to force a spin without knowing that it would be okay.
Cheers,
Karl
