This plane behaves different than all other planes I have with regard to left turning tendency. The AI ball moves to the right and you use rudder to compensate for that. First I made the mistake to install an update that kills the left turning tendency. Then the plane behaved similarly to other planes that exhibit some left turning tendency. That is to bank left and the best way to compensate is with the aileron. I tested soma planes both pay ware and default and found this,

These planes bank left

Aerosoft Katana 4X

Carenado C208 Grand Caravan

these I didn't notice any left turning tendency in

Aerosoft Beaver X

Default Cessna

 

That leads me to wonder if all planes from default to pay ware except the Aerosoft Robin behaves in a unrealistic way in this regard ?

 

Have you checked to see that you are using both fuel tanks? The 208 has a left and a right setting as well as both. Check to see that the ones that bank to the left or right are NOT using one tank.

The left bank started immediately after takeoff so negligible fuel had been consumed. 

Huh?

 

My payware planes have left turning tendencies.

Yes but how ? Like the Robin ? Some of mine also have but they bank to the left

All piston singles have the p factor effect which at high power and crucially a high angle of attack will tend to turn left. The higher the angle of attack and the slower you are going the more this happens, when there are also high thrust settings.

 

Since the p factor translates to a yawing moment, the outer wing is temporarily travelling slightly faster than the inner wing and on some aircraft, particularly those with a small dihedral, that might give rise to a small amount of bank to the left until corrected with rudder. The rudder correction should stop both the yaw to the left and any accompanying roll.

In most piston singles, you'll notice this on initial climb-out in particular.  You'll also notice that when you cut the throttle to idle on final approach, the opposite happens and you'll wind up holding a little right rudder on many planes to keep them centered. 

 

A number of addon aircraft for FSX get both of these right, not least the offerings from the gentleman who just posted.

What is meant by dihedral ? Among the planes I mentioned in my test only the Robin could I correct with only rudder.

One thing that causes a slight left turning tendency in FSX aircraft is asymmetrical loading. For example, if you have a pilot but no copilot/passenger, some planes will want to bank left slightly. The first thing you should try is check the loading screen and add someone in the right seat.

 

Let us know if that solves the problem, as there are other things you can try.

Dihedral is the angle of the wing to the pitch axis. Most planes have some dihedral. It makes them more stable in flight. For instance, the Robin has pronounced dihedral near the wing tips. I flew a single section wing Pietenpol in RL (a parasol wing home built) and it had no dihedral. It's wing was basically a full span plank. Hunted and pecked all over the sky. Had to fly it every second!

 

You should be able to "pick up a wing" with rudder in most planes. I know for a fact that you can do so in the C208, for instance. Try it out a bit more.

I find that the default Cessna 172 does bank left (in a rather unrealistic and sometimes annoying way). As a default aircraft, it's tied to the realism settings in FSX, so you have to adjust the p factor slider to get any results. I also find the highest realism setting to be even less realistic than a somewhat lower setting.

aircraft.cfg file:

 

[flight_tuning]
p_factor_on_yaw          = 1.0
torque_on_roll           = 1.0
 

Adjustment of these figures will alter the propeller p-factor and torque effects.

My loadings were symmetrical. But as far as I understand it's no problem that planes turns to the left since they do so in real life. It's how they turn left that isn't quite realistic.

Yes I have found out that it is possible to correct with rudder but feels easier with aileron. Regarding the

C208 are you referring to the Carenado C208 or the default plane? I used the Carenado and I find very little if any left turning tendency.

Is not that what you do with the sliders ?
