A well mannered fun to fly aircraft.   The usual airshow, look pretty, zoom , do something improbable.    :airplane:

How did you stop the prop while diving?

I turned the engine off prior to the dive.

Right, but in my experience, as long as the prop is windmilling, it remains in motion. Yours was windmilling when you nosed down, but still stopped.

Apparently Hitech disagrees and believes the propeller should stop. Was there nothing else wrong?

Sorry - I wasn't critiquing the flight model; rather, no aircraft that I've flown in AH has had the prop stop, while descending, if it has any kind of rotation (unless you blow your radiator), regardless of whether the engine is on or off. That's why it surprised me to see it moving and then... stop. I assumed you had done something specifically to make it stop. If it just stopped on it's own... weird, but that works.

It may be that the animation continued after the prop stopped in the FM prior to descending. Generally you have to be below a certain speed for the prop to stop.

In the video I stop the engine nose up at 89 mph and slow to 68 mph before accelerating.

I took another look at this and it turns out the film viewer stops the prop while it's still windmilling in flight. You can stop the prop in flight at around 30 mph but the film viewer stops it after the engine shuts off.
