I'm a bit nervous of 'out of the ordinary' spinning in the 2160 for two reasons:
1) The aforementioned acceleration after 4ish turns - One day I met this, applied normal recovery. Nothing happened for a full turn, perhaps a little more. Recovery is usually immediate. I was just reaching the ****.. what do I do now stage when it recovered. Now, the manual does say 'it does that', but..
2) Somebody saw fit to bolt a large 'keel' on the back end. It can't have been a deliberate aesthetic decision, so I deduce it needed some extra directional stability for some reason. Spin recovery perhaps?
I have played with flat, accelerated and even inverted rotation in the decathlon, but I'm a little leery of such things in the 2160. Incidentally, I've also (once) had the decathlon prop stop in an accelerated spin with a near vertical deck angle, and a rather high rate or rotation. Promptly re-started with no worries.
In short, I think there's a certain amount of 'sometimes it just does that' in the stopping phenomenon, whatever the reason..
