  1. I am not sure that this is correct - it works that way when VRAM is exceeded, but if you run out of regular RAM X-Plane will warn you with a message of "X-Plane has run totally out of memory..." - and then quit. Cheers, Jan
  2. You won´t get performance gains with more memory - you will simply avoid crashing the sim. If the sim can fit your scenery into your memory, fine. If it can´t, it will crash. FPS is unaffected by memory size. Jan
  3. We are trying to simulate reality - the equation is: Visual quality x frames/second = processing power. With limited processing power you have to limit both visual quality and frames per second to not break the above law. Until there is enough processing power to have both terms at "lifelike" quality, we will have to make sacrifices in both. Jan
  4. Hi Jose, I think you may be right - the aircraft need to be tuned for the new aerodynamics in 11.10. If there is something fundamentally wrong with the flight-model, it should be fixed. I believe that while Austin may have the "basics" right in theory, it is impossible to really quantify the effect and his calculations may be too crude to really yield plausibel results except for some special cases. I don´t think it is possible to really calculate the spiralling slipstream force on a complex shape like an aircraft, at various angles of attack, airspeeds, powersettings. This is beyond the regime of a desktop flightsimulator and I sometimes think it would be better to err on the conservative side instead of adding some new effect that is throwing everything off... Its correct that the aileron-trim is not really used much in light aircraft, instead the mechanincs will try to "rig" the aircraft so that it flies hands-off wings level in the cruise regime. This may be something that needs to be done to the .acf files to make the planes fly better in 11.10. However, when using the rudder trim in real life to offset a roll, the result will not always be zero-sideslip flight. Rudder trim is not only used to stop yaw. If the cause of the roll was a genuine roll inbalance (engine torque, asymmetrical load, fuel imbalance, etc.), stopping the roll with rudder will produce a slight sideslip. Cheers, Jan
  5. Erm, I didn´t read the whole discussion about rolling word for word - but my simple understanding of aerodynamics and Newton´s mechanics would make me think that in a system with rotating propellers there will always be some roll, in one flight regime or power setting or the other. Engines put out torque, propellers create slipstream effects... trimtabs have different effect depending on speed. It would surprise me if there was NO rolling with different powersettings, airspeeds and prop speeds. Now I know we are all obsessed with one aspect of this simulator or the other - but I think airplanes have trim wheels for a reason and this is becoming a bit of a witch hunt in my view. Jan
  6. That and the "wet runway spray" will get users all the time. The "X" is called airshow smoke and it can be quite useful (to visualize the wind or flight-path, for example). Cheers, Jan
  7. There was some confusing and involuntary revision with the Laminar default airplanes in the beta 7 and beta 8 run. Laminar fixed a problem that set the rate on ALL aircraft to 1.0 seconds deflection (from center to full deflection) - but unfortunately the aircraft files somehow got corrupted, so now the aircraft (at least the C172 and B58 I checked) have their deflection times set to 1.0s. This will be corrected with the next update. You can fix it in planemaker yourself, I think the relevant tab was control geometry or so. You will know when you see it. Cheers, Jan
  8. Hi Jose, you are absolutely right, of course - I did not deflect the yoke (and add a bit of pressure on the nosewheel, too) to show that it is not necessary to maintain directional control. But you SHOULD definitely do so. Thanks for the correction, Jan
  9. Quick update: I DID find my old email sending out the files and have been able to recover them. So if anyone still wants those, email me (JanVogelinButzbach@gmail.com) Cheers, Jan
  10. Hi everyone, I don´t have the package anymore - but of course it is fine from my side to share it. Maybe you can PM each other? Just zip up the scenery pack and mail it. Thanks, Jan
  11. Here is what you can do: Choose to output "engine thrust" to screen. Then rev up the engines until they put out 1500lbs of thrust, each. Note the N1. This is your maximum takeoff N1. Jan
  12. I am not familiar with the engines used on the eclipse, but MOST jet engines put out their maximum rated thrust at about 90% N1. So if you gun them to 100%, you are likely getting 20% more thrust than the maximum rated (the increase per N1 is not linear) and you will also destroy the engines (if they were real) in a few minutes. Jan
  13. Hi, I just tested the C-172 in X-Plane 11.10 beta 5. This is without "resaving" the aircraft, so the new flight-model changes that came with 11.10 should not be relevant. It is not recommended to save a plane in 11.10 until the author has "fixed" it for the new flightmodel, so if someone advises you to do this - don´t listen. The plane is either optimized (and therefore already "resaved" or it is not optimized, and resaving it would mess it up. In the default C-172 (unsaved) I need these flight-control deflections to make it fly straight without rolling (remember, 1.0 is full deflection, 0.5 is half deflection, etc.): Takeoff with full power at ca. 50kts: Rudder right by 0.16 (16% deflection) Climbout with full power at 70kts: Aileron left by 0.04 (4% deflection) Level flight with full power at 130kts: Very shallow left input, too small to measure. Descent with idle power at 90kts: Aileron left by 0.005 (0.5% deflection) So you can see that if you need "30 degrees of joystick" to keep the plane straight like you said, something isn´t right with your setup. I invite you to do the same testflight (and setting your artificial stability to zero is good advice, articial stability is like a kids´ bikes training wheels) and post your aileron input needed to keep the plane flying straight. Cheers, Jan
  14. ok, lets see... 1.) Which aircraft are you flying? 2.) What airspeed and powersetting do you have when you observe the behaviour? 3.) What is your control-response and artificial stability settings (in the joystick menu)? 4.) Do you have buttons/keys set up for trimming aileron/rudder? Cheers, Jan
