You sure sound like one.

If you're correct, the spit guys finally must learn to fly.

I tested Spit VIII (4.09) and Spit LF VIII (4.10) which should be the same airplane, and I can also confirm the trim and torque problems.

I tested the airplane at 2000m, 80% throttle and 70% pitch, which should be roughly the good settings for a fast cruise (at least in this game), thinking that the airplane should have its ailerons pre-trimmed for this kind of flight. Of course, it rolls very notably to the right, unless I introduce heavy skid to the left.

Something else I noticed, and I am quite puzzled by this, so if anyone can explain: in 4.09 Spits VIII, IXc, IXe and HF IXe all show Boost +8 at 500m with throttle set to 80%.

In 4.10 Spits LF VIII, IXc 1942, IXc 1943, LF IXe and HF IX all show Boost of about +10.5 at the same settings and the same altitude.

What is changed? Also, should all of these engines show the same manifold pressure at 500m considering some are optimized for low altitude and some for high? Does this mean that an HF spit is capable of the same speed at 500m as an LF?

@ Swiss - Typical flippant response from a blue-only flyer who clearly hasn't flown anything outside of a 109/190.

IMHO the 4.09 spits were more difficult to takeoff and land, Torque at these points of the flight regime seem reduced in 4.10.

The induced roll in the 4.10 Spits is happening at anywhere above ~200mph and is NOT torque. Torque roll would always be to the left, this is to the right.

Rather, I suspect it is the effect of airframe bias, whereby a little trim is inherently built into the structure of the the airframe, whether it be slightly offset vertical stabilisers, or as in the Macchi series, the asymmetric wing profile. This limits the a/c to being inherently trimmed at only a narrow speed/power setting, with the pilot having to work the a/c trim more above and below these settings.

Whether the TD spits are correct or not I cannot say. I have no proof, documented or otherwise and have not seen their source to comment on the veracity of it.

I will say that in my opinion, the original 4.09s felt more logical as knowing what happens aerodynamically the behaviour could be accounted for. Now I'm not sure why they behave this way - it seems like torque effects are reduced in all flight regimes - incuding climb out and power changes but that has been arrived at by lowering the effective trim speed of the a/c. During all other manouevres above 200mph approx, the Mk Ixs particularly want to drop the right wing.

You my friend, have no idea.
In fact I fly red planes once in while(sometimes you just have to, to even out teams) - however I hate TnB planes.
The spit 25 is my favorite plane whenever I feel the need to correct my k/d ratio - I always get an instant boost of at least 150%, and yes, it works pretty well as a BnZ fighter too.

No idea? Lol!

Hypocrisy is the most heinous of ignorances.

Here's an idea; why not make a constructive post presenting data, documents or relevent experiences regarding 4.10 instead of slagging off an arbitrary number of readers here who fly the Spitfire for no reason than to stroke your own ego.

Cos that's all you accomplish Swiss - no-one else's gonna respect you for those less than subtle digs.

And considering that many pilots I call good friends can take on human controlled Spits in a 109/190/Zero of equivalent year and at least survive if not victor, I suspect you like to boost your ego here to make up for your flying performance - or lack thereof.

So, take your inferiority complex and inflict it on someone else.

I'm also not your friend - people earn that accolade with respect and admiration and you have not proved yourself worthy of either yet.

Oh, and for the record, I'm a P-38 acolyte.

Look fenrir, I don't give a flying f@** about you or your opinion.
May I remind you, you started this argument with quoting me?
And now p.o.
Cheers.

If you are going to discuss the FM, please do it with documents in hand and read a lot, can not use the old FM parameter of 4.09, because it is a game does not represent reality

I do fly the spit regularly, and noticed this a few pages back, yes the FM was adjusted (its in the readme AND the guide!), but I can just trim it out to fly level, not sure what the huge calamity is. I noticed the trim issue, but I found evidence that indicates this is accurate, and this has since been backed up with photos that roughly match the in game spit in level flight.
The spit doesn't have in-flight adjustable aileron trim, so you'll have to counteract slight roll with aileron somewhat, as you had to do in 4.09, and have to do with many aircraft like this. So YES the spit needs more elevator trim, NO it doesn't affect the FM adversely, I just shot down 2 La-7's. There is no need to exaggerate so much about these FM issues so much, and btw the P-51 wasn't "tuned up", it had an error of some 40cm being missing from the fuselage length, which is now fixed.

From the User Guide of the 4.10, first page, section "Main Features" :
"• Revised flight models for all Spitfires"

They maybe tried not to call it ReadMe in order to get people to read it, but apparently it did not work ^^
