I don't know if the F33A or any other aircraft can be fixed, as all of the aircraft I have flown, has this rolling tendency and must be trimmed with aileron trim, with the exception of one. The one exception that I have found is the Beechcraft Duchess, from Leading Edge Simulations. This particular aircraft in my setup does not require any aileron trim at all, and while it may not be perfect in the amount of slip the ball is reporting, once off the ground if you do not use rudder in a turn the ball will slip to the side indicating a need for rudder, and one can center the ball with rudder pedals in a left or right turn. I find that without any stability augmentation in the joystick settings/nullzone, this aircraft exhibits positive stability to a very great degree. I do use some stability augmentation, not because of the aircraft, but because of my FlightSim Yoke, which is very twitchy, it is very old also, one of the first USB yokes that was on the market, without the afroementioned stability augmentation, just breathing on the yoke will cause a change in attitude. It does it in the F33A also,so in my own defense and that of X-Plane itself I use some stability augmentation. Using this with the Duchess, gives the plane a neutral stability rather than a postive stability, it does the same although no to he same degree in other planes namely the F33A from Carenado. The reason for the lengthy explanation, is I know some people sneer at the use of stability augmentation in their joysticks. :smile:It may be the reason for this stability may simply be its a twin engine with counter rotating props, I am not a twin engine person, SEL rated only so can't say, I do know the default Baron 58 wallows around quite a bit though.

Yep! Guess why?Because it uses counter-rotating props, which is realistic given the real thing is built that way... This is, that I know, the only way to eliminate the weird roll moment in prop xplanes....

All of the Carenado planes roll to the right when you chop the power. I've never noticed this flying a real plane.

In real life, they don't roll, at least not as noticeable, but they will yaw to the right if you don''t get off the right rudder input quick enough. Of course in real life the yaw and or the roll is not nearly as noticeable as you have real weight, inertia and all the other physics involved, instead of simulated weight as in the simulation.Of course in the simulator, it isn't just the Carenado planes but nearly every single engine prop plane does it, in my limited experience.Back to twin engines, the default Baron 58, rolls to the right. I don't know if that plane has counter rotating props or not, I've never looked into the possibility, if in the US all twins are counter rotating or not. Not being twin engine rated, and probably not going to be, I haven't looked to learning much about twins. In fact the Duchess is the only twin that I have flown in the simulator to any great extent. Would not be adverse to be enlightened on the subject. :(

No counter rotating props on the Baron. It is whether a problem is with the core sim, or the model.

EXACTLY!!!!!! I've been striving to make my point regarding this limitation in the core FM since v8.... Don't remember how it was back in v7...Thx "Geofa" :-)

[...] It is whether a problem is with the core sim, or the model.

If the Baron doesn't have counter rotating props, ( I was hoping you would weigh in Geof), i would think the problem is with the core sim rather than the flight models, especially as all the single props do this. The only problem I see with this is, the sim should be reacting with yaw instead of roll. Probably the programmers haven't found a way to properly implement this yaw, so the lesser of two evils, do rol,l at least it will start to reflect real world if only a bit improperly. Of course the above is strictly speculation on my part, and i don't want to put words in the developers mouths that is not properly warranted.

Austin is always listening to suggestion. If you can prove it with examples and theories I don't see why you shouldn't give it a try sending him an e-mail about this supposed anomaly in the X-Plane FM. Different from FS, they can change something in the sim in a matter of seconds, you don't have to wait for 3 years before the next version gets released

That's not how it works for FS. A third party developer may change it within days, or when a new comprehensive patch is released. For MSFS default aircraft, a 3rd party developer has usually released a new freeware air file.............for most any type. As to X-Plane................if this anomaly has lasted for years, then what's the holdup?L.Adamson

Maybe it's not an x plane anomaly.I've just spent the last 3 weeks putting my DC-3 through it's paces, and the P-Factor and torque are :good:Never had to put in more than 2° of aileron trim with min or max power. And that 2° of trim was because of bad weather.This is all without any programming and without counter-rotating props.

Good!I happen to like DC-3s. Numerous models around the house, John Wayne's "Island in the Sky" DVD, etc..

Well I've found the aileron trim so it's a bit more comfortable to fly now rather than having to hold left stick all the time!Still doesn't make any sense to me though why it should want to roll right when you reduce to cruise power. I can understand the left yaw caused by the prop torque at high power settings but not the opposite roll when power is reduced!

@ Goran,Can you get a single prop, to yaw or at least not roll like a walrus? How about the Sundowner, does it roll or will it yaw? I hope I don't sound pugnacious or confrontational, or combative in any way. Just curious.I just did a loop around the patch in Morton's Archer III, which is the only single engine prop plane I have had that doesn't roll around. In fact I flew it in the pattern easily without any aileron trim at all, just the right amount of right rudder. Judging by that it is possible to do a single engine prop plane, and have it fly correctly. Perhaps I will have to amend the statements I made earlier in the above posts. What perplexes me is, why don't more developers correct their aircraft models? Surely after all these years, it shouldn't be a secret known to only one or two developers, or is it? If it is, you guys should make a fortune. :( and a :( And I for one, hope that is the case.

Jason Chandler aircraft don't roll to the right when you chop the power. www.air.c74.net.PA-46-500TPPA-46-350PPA-46-310PPA-34-220TPA-32R-301TPA-44-180PA-28R-201PA-28R-200PA-28-181PA-28-161PA-28-180PA-28-160PA-28-140PA-28-235

Glad you weighed in with my favorite Montanan Strider, I have his C172 which I always liked, I am currently at Mumbai VABB so I better give Chandlers aircraft a quick check. Cessnas are very good for flight seeing.
