I think he just wants the best for the game, but certainly there are more than a single attitude in this thread.

Well that's nice. I'm pretty sure most (if not all of us) would like that. Now what?

1: Repeat the wish and it's perception along with some personality attacks and insults to really help it along?

2: Get your own wish thread locked?

3: Rage quit?

4: Rage return?

All good choices Arlo.

It would be nice to have them closer to reality.

As it is now, a huge radial can continue windmilling after the plane has landed on the deck of a CV.............which certainly never happened in real life.

How are you for sure that a plane with Radial Piston engines were not capable of "wind milling", after the plane had landed on the deck of a CV in real life?

I have personally seen with my eyes , E-2 Hawkeye's perform "wind milling" of their engines when I was on the USS Nimitz, while it/they sat on the deck of a CV and after landing on a CV... ( edit: I should have included these were not Radials, they were Turbo Prop's with allisons, more specific Allison T56-A-425 turboprops )

not saying either way, that what you posted is wrong or right, I'm just clarifying that a Radial/Piston Prop driven plane has the capability to windmill it's engines while sitting on a CV Deck, or after landing on a CV deck in real life

from going by your opening post, I see where FLS thought it might be a visual issue verses what the film actually shows. I'm not speaking for FLS, he can do that for himself, but your original post was very vague in it's description of what your wish was.... hence, FLS posted a logical reply

The visual bug is the stopped prop appearing to still rotate. That's different than the rotating prop appearing to rotate.

See Rule #4

hope this helps

I think the question is, at what relative air speed does Aces High currently consider the prop stopped for aerodynamic modeling?  With the related question of whether the prop appears to be spinning in the game or on film at that point.

That is a understandable question!

[Arlo]

I can dig that.

Sarcasm noted, but you forgot the requisite preemptive whine:

"The wind-milling F4U prop should be perked."

But of course.

I'll pull back the attitude which was from frustration at having to explain multiple times that a visual bug has nothing to do with this wishlist post.

Yes, an allison or a tpe331 will windmill in 25mph winds and a PT6 should even more easily windmill since it's not directly geared.

They are not positive displacement engines and have no cylinders that would need to go through multiple compression strokes in order to windmill.

The drag of most any piston engine modeled in the game.......(even likely the storch) should not continue to windmill at 34mph.........unless it had some sort of compression release to make hand propping it easier (doubtful).

The storch should windmill down to the lowest speed of most every plane in the planeset.

I've hand propped planes from cubs to luscombe coupes and up to a 0360 engine size and know for sure that it would take more than 34mph to keep them spinning.

I am not trying to get into this discussion, but bear in mind, the large radials on the F6F, F4U's. R-2800 and 3350's had a large blade area on the prop blades and when they landed, the engine was hot and all metal had expand a good bit and just the carrier speed of about 30knots, running "traps" would be enough to turn the props. That is why in a lot of the pic's you see, a lot of the front row of aircraft had restrains on the props to keep them from windmilling, even when parked. With a "hot" engine, I would think they would windmill quite easily!

Across the deck of a carrier during flight ops is usually more than 50mph....often a bit more.

There's a lot of wind out in the ocean which is why ships were able to sail about.

Let's use the carrier midway's 33 knots and add a 10 knot wind that they would head into.

That's 43 knots which converts to 49.4 mph.

Now in the post above.....how much headwind was there that day?

Is it possible the wind across the deck was 60+ mph when props were observed "windmilling"?
