Sorry Dawger :D
Couple of questions
On the P-38 did you mess with the rotational torque of the engines?
I always thought that the torque pulled to the inside on one engine in Warbirds which is wrong?
Off the top of my head the props should turn outward (on single engine torque should roll the aircraft away from the dead engine).
In real twin engine aircraft, if you have a dead engine, does the torque direction help to minimize the extra weight of the dead engine tendency to roll the aircraft?
Does he dead engine make that side of the aircraft drop?

Anytime I flew the P-38 on one engine I could never trim it to fly straight at any power setting.
I'd always have to apply full rudder and even then it was hard.
I read in a few books that the P-38 could be trimmed to fly straight on one engine.

Many believe that the later versions of the Spitfire turned as well or better then the earlier models.
Adding lots of extra horsepower to anything usually has detrimental effects on handling unless major changes are made to the airframe/chassis.

On the C200, did you manage to find any data on flap usage?
How did you handle its apparent lack of any trim?

On the C.202 and 205, I think you mentioned that the 3D models have CG issues?

Last, do all of the new FMs incorporate the new engine management and fuel burn rates?
WEP is now 100% and leave it on too long and you damage the engine?

The real result is exclusively that EACH pilot has to spend more time with his attention focused INSIDE the cockpit performing a navigation exercise. NOT a great idea in a combat zone. The more time a pilot has to spend with his head OUTSIDE the cockpit, the better off he is.


Happy trails...

Exactly wolf!

Gps, AWACS weren 't part of WWIi.

Hard to get the exact vector to a fight if ots "30 N of f11" cs 2.5.6.7:)

I remember when all S3s were no GPS events.. You 'member?

Hey Dobs, did you get a chance to look at the Pilot handbooks link?
It's still not working.
Will you guys have time to write up pilot handbooks for the the next series?
It looks like Ki-43 vs P-38G and P40 (maybe P-36 :D )
If you want you can send me raw info, and if I have a slow night or two at work, I might be able to put it into a format for the players.

To answer all of this completely would require a book. I will try to shorten it.

All engines driving props produce force that causes rotation around the longitudinal axis of the engine AND produces YAW about the vertical axis of the engine. There are lots of theories and explanations as to why but there is no disputing the forces exist.

For convenience we will call these forces "torque"

So ALL of the engines in Warbirds now have a rotational force increase AND a Yaw force increase.

For engines mounted on the centerline the rotational force is felt very directly. For engine mounted away from aircraft centerline its affect on the aircraft is somewhat balanced out as long as the corresponding engine on the OTHER wing is running at the same power.

So on a four engine plane with all engines turning the same way the aircraft will YAW quite a bit at full power and low speed but will display relatively minor rotational effects with all engines operating.

In an effort to counteract this some multiengine planes of the WWII era had engines that turned OPPOSITE directions. The P38 is one of those. With both engines running the yaw and rotational forces are in balance.

Kill one engine and the remaining engine produces its normal Yaw force and rotation force PLUS extra yaw force from being away from aircraft centerline. Lots of people have died after an engine failure by getting too slow and "torque" rolling the airplane.

The P38 had engines that turn outward (Left is counterclock and right is clock)

Modern twins turn inward because it has been found that the greatest yaw force is produced on the downward stroke of the prop.

The P38 has the same higher "torque" forces applied as all the other models and will not be a lot of fun to fly on one engine below 130 mph.

..............................

I made assumptions regarding the flap system on the MC 200 in the absence of evidence.

For aircraft with proof of no trim on rudder and aileron, it has been removed (A6m Series). IN the absence of proof, It is a judgement call. I would guess from the date of design of the MC200 it did NOT have rudder and aileron trim but it is a guess.

Macchi 202 and 205 (and the 109 it was derived from in game) do have a weird cg placement but I was able to make the FM's work pretty well.

....................................................................

Overheat resulting in engine damage is an Arena Setting applicable to all aircraft. Engines will only heat up when in a BOOST level, the rate they heat up in each boost level is set in the FM, time limits for BOOST levels EXCEPT water injection have been removed from the new motors and the temperature that damage CAN occur is 145 degrees in the HUD BUT it can be set to anything a CM may desire as a global arena setting. I have used 160 degrees in the AFMA but at the moment it is at default.

All models that have the new Multi Boost motors definitely have the new extra high fuel burn in Boost levels.

Old motors may not but only if I missed them when reviewing.

I have not written new handbooks. I didn't get much feedback on them and they are time consuming to do.

They certainly would be great thing to have with all the new stuff that is in the FM's now but I don't think I will get to them soon.

This is the point of a No GPS event.

Our present ability to have instant position information is extremely unrealistic.

And its not like we don't have other tools built in the game that make navigation easier than it actually was. We have .vor command that give radial and distance to a known point and this is more than was available to WWII pilots.

NO GPS would put a higher premium on planning and sticking to the plan as well as require some actual head work in the cockpit to be successful.

I havent messed with the P36 FM this summer.

Is there some reason to change what it has right now?

We used it for Pearl Harbor and I didn't get any great amount of feedback either way on it.

Our last conversation about the P-36 found the models CG was off. That's why there was a major push to get the proper cp in. We couldn't fix the CG using the p-40e cp.
CG is correct now.
