OK, good to know you are aware of his work. I think it's the most detailled and pushed cockpit and exceeds by far a simple painting (with adding and refining lots of elements in the cockpit).

Anyway, one day it'll be implemented, I'm sure

Best regards and thanks for the quick reply. Hope everything is going well in the testing of the 4.10.

Hello team daidalos, i like the work you've done for il2.

But theres a thing that i noticed when flying the SM79: it turns like a spitfire.
I think this isnt accurate, maybe this needs a fix from the upcomming patch.

thanks

Well, indeed, most aeroplanes turn exactly like the Spitfire: when wings are not level, you pull the stick and move the elevators. Result = a turn. I really can't see how this is not accurate. SM-79 has ailerons on wings so it can roll, and also has elevators in the back.

Also, if you pull e.g. 3 Gs with SM-79 and 3 with Spit, yes, your turn rate at the same speed is pretty much the same. Can SM-79 handle even that much after 4.10 for longer periods, is another question.

According to IL2 Compare with the 4.09 data tables the SM.79 doesn't have anywhere close to the Spitfires turn rate. What it does have is very low speed turning capabilities which is not unusual for bombers. It's still not very fast at all.

I was very impressed with the turn rate of a B-17 I saw at an airshow once. It can really turn quickly when not weighed down by bombs and ammunition. It doesn't mean it turns at fighter speeds like the Spitfire does.

That's my experience taking a hop in a B-25 a few years ago...

She felt pretty spritely with no bombs, guns, crew with full gear/parachutes/sidearms, and with the very heavy tube radio equipment replaced by modern solid state gear. And this was on the current 100 Octane Low Lead Avgas that limits maximum manifold pressure. (They did run it up to 41" on takeoff though...).

Gee, I didn't know there still were people who took IL2 Compare so seriously.

[Azimech]

What's wrong with IL2 Compare?

so much wrong here ..

You start a turn with rudder at the same time banking with ailerons, as well as applying elevator

just pulling on the stick, thus moving the elevators doesn't result in a turn at all !!! .. it results in a change of pitch .. in a diving turn from level you might even push on the stick a bit to properly make the turn

it's the correct application of yaw (rudder), roll (ailerons) and pitch (elevators) at a particular speed that result in the best turn rate

G-force equality does not co-relate directly to turn rate / radius at all between different aircraft !

Sorry, but this is demonstrably false in IL-2 and also in real life. Fly straight and level, roll the plane into a bank using ailerons alone - it will start to turn. With any significant bank, the nose will also tend to drop, so you need to pull back on the stick to compensate.

The only use for rudder in turning is to 'keep the ball centred' - to avoid sideslipping or skidding. In tight turns with a prop-driven aircraft, most of the forces generated by the rudder are needed to counteract the gyroscopic forces from the prop, which is why you find yourself having to apply 'inside rudder' when turning one way, and 'outside rudder' when turning the other.

And at a given pressure altitude, airspeed and angle of bank, in a coordinated turn (i.e. no sideslip), the radius/rate will for most practical purposes be the same for any aircraft. This is down to simple physics.

<sigh> .. gotta love bank and yankers .. or was that yank and bankers ?

you roll a plane using ailerons, not elevator

of course, once you are in a bank, it's the application of elevator that results in a turn

it's to greater degree engine (and prop) torque than gyroscopic precession that results in the need for rudder compensation depending on direction of turn, even in WWI rotaries .. just go check technical articles at Old Rheinbeck to confirm

and though I've directly asked Oleg, TD, and others familiar with the IL-2 FM. I've never been able to get an answer whether IL-2 FM simulates gyroscopic precession at all .. something I'd like to know for putting WWI aircraft into IL-2, where the effect is needed for proper fm on rotary engined planes.

regardless .. from my experience, *kicking* the rudder slightly in IL-2 can result in a quicker turn . and I make slight rudder compensation during the turn with good effect as you describe

Read carefully combat flight training manuals, and you'll find judicious rudder use is an important component in starting turns and maintaining them

the physics are not "simple" .. weight, wing area, wing foil profile, control surfaces' design, prop thrust and several other factors come into play regarding potential turn radius .. easy to demonstrate in IL-2 or even in a 12+ year old Red Baron II/3D Advanced Flight Model, that does simulate gyroscopic precession

or we can just agree to disagree
