Hello all,

 

On my computer, the default Cessna 172SP has this terrible tendency to bank to the left in level cruise flight, not only during climbs, where this tendendy is expected.

I have to fight the aircraft so it maintains course.

I have the Carenado's C152 and C172N, and of course, flying those are a whole new ball game. But my interest on the default aircraft is because this book I'm using to train fro real world flight, and it uses the default aircraft.

 

I have seen many people complimenting the default C172SP as a great flight model, others, like me, having problems flying this aircraft. Oddly enough, I do not have any problems with the other default aircraft.

 

What I'm looking for is not an entirely new flight model, but to add stability to this plane.

I have made modifications to the aircraft.cfg file, changing the roll, pitch amd yaw stability from 1.0 to 2.0, and that seemed to help a little.

However, I have read elsewhere that the real changes take place on the .air file.

 

I have the editor for this type of file, and if someone already had this problem and solve it, that please, help guide me to solve this problem. 

 

Thanks.

 

Is it possible that the plane isn't loaded symmetrical? I guess there will be a noticable bank tendency if the pilot is the only person in the plane.

I may be wrong..... The cessna has only one engine, on take off it does tend to pull to the left...I find that inputing right rudder helps keep it straight till autopilot is engaged......could be totaly the wrong solution...hope that helps you..........

That's definitely right, and probably what everybody would expect, but as far as I understand it this is only valid for high power settings, such as during take off and initial climb. However, the OP's problem appears during cruise, where high power settings actually shouldn't cause such behavior.

Aileron trim? Engine torque?

I used to have this problem with the default Cessna. Then someone told me the max P-Factor setting in FSX is unrealistic and to adjust it down (in FSX Settings). I did that and all was well. It still pulls to the left on high power settings, but not in cruise.
