Interesting that on the second turn the glider gets nose high. I have spun 2-32, K-21, ASW-24, North American SNJ-5, Ventus 2c, Nimbus 4 (quarter turn only), citabria, champ, Decathlon, maybe something else but I have never had the nose go above horizon. Can anyone tell of their experiences in a spin like this. The two most interring things I have had happen was one particular 2-32 would do an over the top spin enter from a deep slip and another would go from spin to spiral by itself.


Piper Super Cub was the other aircraft I had spun without ever having the nose point above horizon. I have had oscillations but nothing like the second turn of the JS3. Would like to understand a bit more about this an if there are techniques to keep the nose from going high other than recover sooner. Any shared experiences or comments welcomed.


Its the same with the JS1. I doubt that you can prevent that by anything you do from inside the cockpit and it doesn't affect the conventional spin recovery. As two types have completely different fuselages and wing mounting positions I guess it is a characteristic of the shared T12 airfoil and the very similar planforms (the JS3 wing being derived from the outer almost 9m of the JS1c 21 wing).
