And an important detail of the RC helicopters is they have rigid blades (easy when the rotor is a foot in diameter) so the flapping problems don't apply. The Bo 105 operated by Chuck Aaron has rigid...

I suspect the main problem with loops and rolls in non-aerobatic helicopters (i.e., most of them) is stuff like blade flapping, mast bumping, and other perturbations that result from gyroscopic...

Yes, there's an "AI flies your aircraft" option in the Aircraft menu bar heading. No choice of route or destination, though. It just takes over the aircraft and does what it feels like.

Yes, as long as you've already gone to the trouble of setting up Bootcamp and Windows. The Apple nVidia drivers do not run the card at full performance, and people have reported as much as a 2x...

It depends on which graphics chip your MBP has. If it's ATI/AMD, run X-Plane from MacOS. If it's nVidia, run it in Windows. The difference has to do with the quality and performance of the graphics...

Unfortunately you can't. The view controls got significantly redesigned in XP10, and in particular the right click style view control in the 3D view doesn't exist in XP9.

Yeah, Ben's been working a lot on the lighting in the last couple updates.

As regards the fuel flow... I haven't played with the recip engine model recently, but I've noticed a number funky things...

There's a separate control function in XP9, called 3D with mouse look (something like that). It's assigned by default to control-O. It's not nearly as convenient as the way it works in XP10, because...

See here for NACA TR-824 - the plots for NACA 2412 are on page 394 (as printed in the image). It's symmetrical enough in terms of slope. And the zero lift AoA is -2 degrees as I said. Look at the...

I'm going to beg to differ with you, at least in terms of the control authority available in the airplane. Here's my reasoning:

The 172's NACA 2412 airfoil has a zero lift AoA of -2 degrees. Going...

I don't see that there's anything unique to X-Plane relative to this problem. You're just seeing the well known "CB radio" syndrome at work, where rudeness increases proportionately with the...

This is inaccurate. According to the TCDS, a Cessna 172 is rated in the "normal" category of operation for +3.8 to -1.52 G, and +4.4 to -1.77 G in the "utility" category (with restricted gross weight...

Are you seeing any response in the Axis setup page of the joystick settings menu? I'm not sure if the throttle axis gets assigned by default. You may need to set it up yourself.

What's strange about gliding upside down? (Other than hanging from your seat belt might get uncomfortable after a while.) The wing can generate lift in either direction. It's just more efficient...

Indeed it is. I was just following Larry's language.

Nope. Newton's third law always applies. It doesn't matter what the cause of the force is. (Strictly speaking, BTW, it's opposing magnetic fields that are repelling each other.)

Excellent discussion - thanx for the link. My overall assessment: Bow to Lincolnshire 5 times a day and repeat after me, "Conservation of angular momentum". It is one of the holy grails of physics....

If you can't read just disc #3, it's in all probability a bad disc. These happen occasionally. They are double layer DVDs, which are fussier than normal DVDs. As long as you bought the kit halfway...

It really doesn't make any difference, since it's all a discrete/sampling simulation anyway. And X-Plane doesn't model stress on the wing elements, just G-load on the the airframe as a whole....

The stock 172 model got a considerable amount of flight model tweaking in 10.21 to make it more accurate. Among other things they finally cut down the size of the prop so the revs are up where they...

How long ago did you buy the kit? (And BTW, did you buy it new or used?) Everything I've heard in the past says Laminar is pretty good about replacing bad discs, but there's a reasonable time limit...

Strikes me as a bit of a stick in the mud attitude. The new aircraft features in XP10 are relatively limited and incremental - the big deal in XP10 is the rework of the scenery and graphics engine,...

Thanx for this point - I hadn't heard this one before. That's one of the reasons I have these discussions: every once in a while I learn something new. I'll have to dig into the flight model and see...

Those of you that have read my earlier replies in this thread know that I've been after the roll problem for years. So... let me inject a little bit of facts and experience into the discussion.

I wouldn't try to turn on HDR, and I'd keep a lid on the cloud detail. But it will handle a decent level of anti-aliasing that res and otherwise do a good job.
