I believe this is what changed, at least for the Maule and the RV6, althought it wasn't listed in the list of modifications announced with the patch...

 

Actually I don't think either p-factor or slipstream were indeed changed...(to be honest I don't even believe MS ever modelled p-factor...) Both account for yawing moments, and p-factor affects primarily tailldraggers during takeoff, ile slipstream has it's effects under many flight situations.

 

Torque seems to be the "prop effect" that reallly got "edited" for this patch...

 

The lift coefficients of the flaps in the Maule also apparently changed, and I do believe parasite drag was also tweaked....

 

This, IMHO, should have been mentioned... The Maule really feels different, and at least for me (who never landed such an airplane and so might not be entitled to give this oppinion...) the landing is not so realistic as before - the airplane sinks a LOT more...

 

I can now also reach top speeds way above the red line during descents....

 

Well....

I like the more pronounced left-turning tendency, finding it more realistic. It's taking me back to the days of my flight school's crusty old Chief Pilot stabbing me repeatedly in the leg with his ballpoint pen chanting "right rudder, right rudder!"

 

P-factor, torque, whatever it is, simply wasn't very significant before. Now, you have to manage it, especially in high angle-of-attack situations where it really should be a factor.
