ok folks... I think this would be as good of a thread as any to write up what aircraft has the RIGHT vs LEFT torque.

As far as I remember, the only few aircraft that turns and rolls RIGHT better than left with any measurable difference are the:

Typhoon, Tempest, and Spit14.

If there is any question to which way a prop is spinning just kick on WEP and watch the plane dip in that direction.  Or, get the place up to 250 TAS or so and cut throttle all the way and then hammer down, the wing will dip doing that as well (take it out of auto pilot). 

The La7 dips its left wing telling me the torque is taking the plane left which tells me the plane rolls and turns better to the left (at least in theory). 

The IL-2 does dip the right wing when testing torque so I did learn something today as I always thought the IL-2 went left better like most aircraft in AH.

Some say Yaks turn better to the right.  Do we have any facts to prove this?

Dunno... I will test it though.

One thing for sure is this: A P38L will eat a Tempest alive in a scissors while at high speeds... even when loaded with %50+ fuel, 2/1k bombs, and 5in rockets.  I was part of a mission when I was intercepted by a Tempest and my only thought was to get him away from the allied bombers so I went nose down (we started at 20k) and turned °90 away from the bombers.  The Tempest followed me down and somewhere in the mid 400's I started to shake with him 800 behind me.  I gave him his better roll and took him right °90 and then let me catch me, he was 600 behind me at that point. I then took him °180 left and cut throttle a wee bit... and he went right on by.  I hit the throttle and kicked on WEP and followed him up (I had forgotten about all the extra weight by this time), I got to within 400 yards of him when we both stalled out (after I missed my shot  :bhead ). We both rolled back under and did a full loop where wouldn't ya know it we were setting up for the HO.  He won thanks to my bad aim that day.  However, I did see him trailing oil after we collided.  So ultimately, I accomplished my mission and get him away from the bombers.

I can certainly vouch for how well the P38L can roll at high speeds, heavy or light.  Wowza.   :O

The quick way to test the way the engine turns is to just sit on the runway and start the engine. You get an instant answer.
The planes that have engines spinning to the left:
Spit 14
Tempest
Typhoon
Yak 9T
Yak 9U
IL-2

and 1/2 of a P-38!

They will all turn with better stability to the right, but may not make tighter turns or faster turn rates. It's just a lot easier to make them do that.

Interestingly, I find the Mossie with it's two right hand engines easier to turn to the right, which is counter-intuitive. I don't know if it's because as pilot I'm sitting on the left side of the plane, or what.

radials are direct drive, early vee's usually have a drop box so the rotation is reversed. some of the later h's were direct drive, some were drop boxed. of course the final rotation depends on the actual engine rotation.

With the Typhoon and Tempest both it is easy to feel the torque as the plane wants to turn and roll right by default.  Any movement to the left and they fight you, or rather a more heavy hand is needed (and more time).  I didnt notice the Yaks so much and same goes for the IL-2, none of them seem to have the awesome torque as the Typhoon and Tempest.  FWIW, I don't think any aircraft is adversely affected by torque as much as the Typhoon is.
