Actually my Nimbus 4 was an honest spinner. Once while thermaling in a valley very close to the moutons a gust tried to get a spin developed, normal recovery. Prior to this I had done a number to spin entries followed by normal recovery. I never let a spin develop as i would not in normal flying either. There is a wait time while you wait for a control surface to dig in, but all in all I thought it was honest a normal. I also have several hundred hours in a Nimbus 4D. I found the 4D flew considerabily different than the single seat Nimbus 4.

The rigging is very important on a Nimbus and when I first got mine is was rigged horribly and flew horribly. Fixed the rigging and it was a beauty to fly.

How can they get certification if they come apart recovering from a spin?

Boggs

You can recover from a spin, but you'd need to be sharp. You miss a beat, you'll loose a wing.
Not sure whether a glider 25 m is required to undergo spin testing for certification.
