  1. From what I can tell, if the 1400 sections are in the air file, then autorotations are possible, but no other helicopter things work, like tail rotor translation, torque vs collective, mast tilt, etc. If the 1400 sections are absent, and the aircraft config file contains all the updated ( since FSX:A ) entries, then everything except autorotations will work. So, either way, you are screwed, unless you have external code, such as HTR or something else ( dodosim? ). Unlike aircraft, the config does not overwrite the air file, if the 1400 sections are present.
  2. Also check that the yaw damper isn't turned on
  3. The reason for knowing TAS is to find groundspeed. If there is no wind, they are the same. Why would you want to know TAS if you know GS?
  4. Length of MAC = 2.4006 m LEMAC = 9.5025 m from zero
  5. You would need to change the values in the air file, assuming the gauge is even reading sim values. Some custom gauges don't and so in that case, it probably wouldn't make any difference. Convert the temperature to R, then scale it appropriately.
  6. The drag curve is near perfect. The best glide is 135 knots at 15000 lbs with a ratio of 14.1. The book says 2.3 nm for every 1000 ft ( 14 to 1 ratio ). So, we're off by 0.1 The stall speeds clean and with flaps are within 1 knot, as is the Vmca. The rudder boost function works The normal/max cruise performance is also within a couple of knots, using 100% torque and 1500 rpm The pitch stability was determined by analyzing the wing/tail combination, using CFD, so I believe that the trim speed vs weight and CG is also very accurate.
  7. I had flickering when running in a window. Going to full screen mode stopped the flickering, as did turning on V-sync from within P3D, when in a window. Nvidia 1050Ti, latest driver
  8. In the aircraft config, reduce yaw stability to about 0.1. That works for most airplanes with that problem. It's a good place to start anyway. The problem is over-dampening and so the plane carries too much sideslip in a turn.
  9. Scott, I'm not seeing 5-6 deg. I can tell you exactly what the angle is. At 5000 lbs, the lift coefficient is 0.917 ( the flaps contribute 0.3 to that ). This occurs at exactly 0.0773 rad ( 4.4 deg AoA ). On a 3 deg glide slope, the nose is up 1.4 deg. If I could figure out how to attach a screenshot here, I would.
  10. An update has been posted in the Milviz B55 support forum. If you don't have access, contact Oisin and he'll hook you up! Changes - Corrected weight and balance for 6 seat configuration - Corrected engine power output and fuel consumption for given power setting ( power and fuel consumption were high ) - Corrected cruise speeds for a given power setting ( the airplane was 5-10 knots fast ) - Changed the zero lift angle of the wing by 1° and raised the viewpoint by 1.2 inches - Added a bunch of extra internal and external views
  11. Hi Scott, The update to v4 is available from the Milviz support forum for the B55. That is also where the FDE update will be posted in the not too distant future.
  12. I know from researching Beechcraft airplanes in the past, that they do not provide as much information as other manufacturers do, with regard to aerodynamic particulars, and so it is understandable that it would be more difficult to make a flight model for such an airplane. Also, it has been several years now, and there are perhaps more resources available online than there were back then. I did fly it and I see what you mean. I was able to find the POH and service manuals. There are two things to look at, 1. Viewpoint - I was able to improve forward vision by just raising the viewpoint a little bit 2. The zero lift angle needs to be verified, given the incidence, airfoil sections and twist/washout of the wing design
  13. That would be me. I love the twin comanche. It was/is a pleasure to research and make this airplane fly according to what aerodynamics/physics predicts and to match pilot accounts of flying it. Our beta testers seemed quite pleased with it. Of course, we will continue to support it and correct any problems as they occur. On that note, I am willing to review the B55 as well.
  14. The default AP keyboard commands work. Press Z to turn it on, then Ctrl-H for heading hold, walk away from your computer if you have to. Scott, it's not like the B55 😉
