August 17, 201015 yr When playing on full realism settings and taking off in the default C172, I start to notice a lot of left-yaw (which immediately translates into left-bank). Presumably this is from the propeller slipstream (or p-factor, if it even matters on such a plane). I've never flown a C172, but it seems to me that this effect is really overdone -- with no rudder pressure, I almost immediately go into a left bank that hits the second notch on the turn coordinator. I suppose I have two questions:1) Is this realistic, or is this way overdone?2) If the answer to 1 is "overdone", what are some better C172s that don't have this effect?Thanks much.
August 17, 201015 yr It's overdone, but check the wind direction and speed, you can minimize it by using a runway that is closely aligned with the wind, if ones available, Use rudder to counteract it, and lower your FSX realism settings as well. Real in FSX aint necessarily real in real life Jay
August 17, 201015 yr I've got a bunch of hours in the C172 (one of my favorite real planes) and I can assure you that the P-Factor in the FSX model is totally unrealistic. This pretty much holds true for all the prop planes. I've found the only way to get it close to real is to have the P-Factor, torque, and gyro settings at or near their lowest settings. I've also noticed that if you have these up a couple of notches it affects your taxi too. Thank you.

August 18, 201015 yr This can actually be a hardware issue.. I have thousands of real hours in light singles, and find the 'p-factor' in the default c172 quite realistic.. IF you're using accurately calibrated rudder pedals. My takeoff rolls in FSX are just like the real thing... start with a bit of rudder, and adjust it as you go, not really thinking about it.
August 18, 201015 yr Alexander Metzger from Digitel Aviation has made some superb flight dynamics for the default C172 amongst other planes. I highly recommend to use his files.You can download the flight dynamics from Alexander's website. They are freeware!http://www.metzgergva.de/site/index.php?option=com_content&view=article&id=2&Itemid=39〈=en Wolfgang

Any opinions on how they compare to the Flight1 or RealAir dynamics?

I read this subject for the last two day's, and was thinking, "not so". Just like the real thing, I also use what's required, and don't think about it. Note: I'm here because a deer, my motorcycle at high speed, and me didn't agree. No more real flying for a while..:(L.Adamson

I hope you're recovering nicely.. glad you popped in..(now for a lecture.. :( ) We pilots know we stretch the truth a bit, when we tell people that they're statistically safer while flying with us, than they were driving to the airport.. though it's true enough to pass.. BUT riding motorcycles IS a statistical disaster, waiting to happen to you :( Seriously though.. hope you're doing well ..

Happily, I was wearing a full helmet. Broke all ribs on the left side, collorbone, and shoulder blade. Punctured kidney, and a lung that wouldn't work for a while. I have deep road rash everywhere but my head. This was at 60 mph on a 1520 cc bike. My collarbone was put back together last week with an 8" plate & screws. This happened four weeks ago. Just that morning, my wife told me to be careful, as she usually does. I asked, "would you prefer the motorcycle or the airplane"........since I was going out of state. She didn't reply..............but now I think the plane is perhaps a bit safer. This particular "deer" didn't even give me a second to react. And living in the mountain west, I've seen many deer over the years.L.Adamson --- now back to subject :)
August 18, 201015 yr That makes me cringe larry. Here's to a full recovery and getting back airborne.I agree with what both Mr. Adamson and Brett said by the way. The Left turning tendancies are pretty well done in FSX. In light singles if you don't make that correction when you lift the nose the left yaw is very pronounced, and once the mains come up you'll see the left hand roll pronounce itself as well.

In light singles if you don't make that correction when you lift the nose the left yaw is very pronounced, and once the mains come up you'll see the left hand roll pronounce itself as well.I don't know though -- a roll right to the second notch on the turn coordinator? And I'm not talking about that when it's climbing, I mean straight flight. I mean, I can understand a little, but that's a *lot* of left yaw. I've never flown a C172 though I have about 15 hours in an old Piper Cherokee; I don't remember anything this quite extreme.There's nothing wrong with my hardware; happens on the keyboard too. Try it out yourself, keyboard only, with and without auto-rudder. (Unless you have a curved runway, you should probably turn it on while taking off then turn it off once you're straight and level.)Sad to hear about the motorcycle, Larry. Hope you recover fast. (I've been wanting to learn to ride myself this summer, didn't happen though. Maybe next summer!)

Try it out yourself, keyboard only, with and without auto-rudder. (Unless you have a curved runway, you should probably turn it on while taking off then turn it off once you're straight and level.)On my system, the default Cessna 172 will settle to a wings level attitude at cruise speeds. It still requires small corrections because it's not on auto-pilot or "flying on rails" as they say. While rolling down the runway, and climbout, the Cessna requires right rudder. 172's use a fixed ground adjustable rudder tab thats set for cruise speeds. Since these speeds will vary, it will never be perfect. The model actually simulates this fairly well. And for these test purposes, I have realism set at full. I'm not using keyboard, and use rudder pedals. With no pedals, I prefer "auto rudder". With my Saitek pedals, it's nothing extreme in regards to the amount of pedal used.Fuel and passenger load will also effect "roll" stability in these models. Check that too.L.Adamson
