  1. This applies to pretty much all aircraft I tested, but the Spitfire is a good example... It can be flown inverted for as long as we wish, eventually starting to lose the engine, but the oil pressure gauge always indicating no variation at all ? Systems modeling simplification ?

    Spitfire elevator...

    Well, I tried using 50% ( technochat ) nose heavy trim with no success - had to constantly pull the stick, and had to trim it back to near true neutral inflight... Will check again. I do not have FFB. How can we send reports to the Devs ?

    Spitfire's torque effects ?....

    P-Factor is the asymmetric contribution of the prop blades to the generation of thrust due to their angle of attack, also known as asymmetric disk effect. It is present whenever there's an angle between the relative airflow and the axis of rotation of the prop. In a CW rotating prop aircraft, and when pitched up, like on a taildragger during the takeoff and while the tail is down this asymmetry translates into the downgoing blades ( or the starboard side as seen from the cockpit ) having a bigger angle of attack than the upgoing ones thus creating more lift / thrust and pushing the aircraft nose to the left. Regarding that description you make of the CoG, I guess you're experiencing the effects of the aircraft showing neutral static pitch stability under most flight conditions. It is nicely modeled in IL2 GB, IMO, although sometimes I have some questions regarding this or that features, but overall I'd say IL2 is actually my preferred feel of flight among the many many flightims I have used for more than 2 decades πŸ™‚

    Spitfire's torque effects ?....

    Exactly Zacharias, and thx for going to try it πŸ™‚ I mentioned the corkscrewing effect ( called it slipstream ) and in those climbs maintaining next to 100 MPH or even less, at full power / rpm, sometimes even keeping the undercarriage down, I do believe really high AoAs are reached. Then again, sometimes there appears to be also very faint need to use the rudder to clear the resulting sideslip. I'd say these Spitfires appear to be very benign in as far as prop effects at high power / rpm and AoA go... And yes, since it uses frise-type ailerons, the Spitfire should be optimized regarding adverse yaw. Looking fwd for your tests and comments πŸ˜‰

    Spitfire's torque effects ?....

    Thx ZhacariasX, but appart from the "pure" torque, there's also the P-factor and the asymmetric slipstream hit of various aircraft surfaces, all contributing to a left yawing tendency (*) and, I believe, also some induced roll ? If you get the time please give it a try. You can start from an Autumn map, fuel at 65%, no amno. Takeoff and pitch it up to the limits, keeping around 100 MPH IAS in your climb... Make sure you turn the rudder trim to neutral. I usually hit the "reset trimmers" key and then add only the pitch trim before starting the takeoff run... (*) although actually the vertical fin & rudder being hit portside could actually partly compensate the left rolling tendency...

    Spitfire's torque effects ?....

    Or, the absence of it.... Would really like to see someone from the Devs team offer oppinion on this. The IL2 GB Spitfires are - IMO - modeled in a rather "faint" way regarding prop effects... We can perfectly takeoff, even setting the rudder trim tab to it's neutral position, climb at the highest possible slope angle, and it's suprising to find that initially it even appears to "want" to roll right after leaving the ground, and then you practically don't have to add any stick ( right stick ) to level your wings (?) or rudder to avoid sideslipping (?) Tried it at various fuel & amno configurations, clipped wing version too, and it's the same... You can get to extreme AoAs, and just a tad before stalling does some Anti-Clockwise rotation start to develop πŸ˜• Given that I have IL-2 GB on a high mark regarding flight dynamics, I would like to be told this is the correct behaviour, because at least common sense tells me it is plain wrong...

    Spitfire takeoff stick deflection

    Yes, pretty much all of the four "torque" contributors: .) Engine / propeller torque .) Slipstream hitting various areas of the fuselage, wings and stabilizers .) P-Factor .) Gyroscopic effect as the tail lifts off the ground in a taildragger all sum up to create the left yawing tendency in a CW rotating prop aircraft. Anyway, in IL-2 the Spitfires are modeled in a rather awkward, unexpected way regarding torque.. We can perfectly takeoff, even setting the rudder trim tab to it's neutral position, climb at the highest possible slope angle, and it's suprising to find that initially it even appears to "want" to roll right after leaving the ground, and then you simply don't have to add any stick ( right stick ) to level your wings ?????????????? Tried it at various fuel & amno configurations, clipped wing version too, and it's the same... You can get to extreme AoAs, and just a tad before stalling does some Anti-Clockwise rotation start to develop πŸ˜• Given that I have IL-2 GB on a high mark regarding flight dynamics, I would like to be told this is the correct behaviour, because at least common sense tells me it is plain wrong...

    Spitfire takeoff stick deflection

    I also miss the "down deflection" of the elevator under most circumstances, in level flight, compared to many RW videos and pictures. Regarding the deflection of the aileron on the above extracts from the video, while it's true that is it useless at the beginning of the takeoff run, it will help as soon as airflow over the controls is effective, and this way the pilot will not "forget" to add it later πŸ™‚

    Need help from Devs please

    Anyway, no other Spitfire feels like the IL-2 Spitfire! So it's worth waiting for a solution :-)

    Need help from Devs please

    Ok, I'm going to be really helpful here and suggest you send it all to me, and I'll try to figure out a solution for you... Ok ? πŸ˜‰ Hey - that looks really Cool !!!! And I hope you can sort it out...

    MW50 weird behavior

    Yes, and before the K-4 get's released - it would be really sad to see it down-rated.... ( Hey, see?, I'm ( ---> ME <--- ) actually talking ww2 engine stuff !!! not knowing the slightest about it.... )

    Can we give away our promotional codes ?

    I already gave away mine to some guy who PM'd me as he saw this thread :-)
