icepac I love you to death, but I am still wondering what your wish is about.  actually more like how does it affect gameplay.

Being able to stop the prop is the difference between dropping like a stone or gliding enough to make it home.

I'm sure all the LA7 guys who up with 1/4 fuel would appreciate this.

Reduce rpm in the F4U and it'll glide rather well, actually. I'll post a glide video in the film thread.

All his point is, is the glide path is different between:

High RPM windmilling
Low RPM windmilling
Stopped prop

In order of most to least drag.  I don't know what the proper speeds are, I don't know if what's in the game is right or wrong, but it would be neat if it reflected reality I suppose.

High alt bomber hunting, I do a ton of dead sticking home.  If it's as big of a difference between windmilling and not windmillling as icepac claims, it's worth stopping the prop in some situations.

I just posted a film of making it home a sector away on glide. I took off from that base on auto-climb and a quarter tank. When the fuel ran out, I turned around. I should have reduced rpm right away. I did about 4 minutes into the film. On reflection, I'm glad because it shows what a difference dropping RPM makes. There was no 'dropping like a rock' involved. In game, the prop windmills. In film, it doesn't. A visual glitch. I was travelling at an airspeed of between 100 and 150 and had a rate of descent between 3.5 and less than 2 (the latter two achieved by reducing rpm). That may be why the wish doesn't seem like a huge deal to many. But then, an open canopy wish would be much the same and I'm cool with that. I'm cool without it.  :) :cheers:

In an I16, I found descent of 2200fpm with prop stopped and 6500fpm with prop windmilling.

Yeah.....I checked the F4u1a and tested the descent in the 3 most common options and am pretty impressed how HTC modeled it.

I can retract the wish but will certainly still be able to glide further than 99% of the players.

So what is the exact speed the prop stops on every plane? Being your so unimpressed you must know the speed of each plane within 5 mph.

I can tell you from experience that with the Cessna 182 (Continental O-470) and Cessna P206 (Continental IO-520) the prop doesn't stop until roll out after touchdown.

I provided all the details.

Surely enough that a trainer could figure it out and not lead off in a tangent totally unrelated to the wishlist post.

Your ad hominem attacks aren't helping and add nothing usable to the discussion.
Damn ice. call down. You cant go no where with out issues.
