Fixing Roll

[smink1701]

I'm noticing in a number of planes that they want to roll to the right. I tried to assign aileron trim to correct but it doesn't seem to work. Any one have a fix?

Thanks

most of the fighters don't have aileron trim, and the roll right is an effect of torque.

Oh.

Thanks

Yes it is torque, however the effect is a little exaggerated at cruise I think. Be good if the effect curve was slightly less steep as at say 50% power there is still quite a roll more akin to full power in my opinion. Most aircraft have bendable trim tabs on the ailerons that the engineer can adjust to balance the aircraft for the cruise.

Trim the ruder (ctrl + Z or X) some of them are misplaced from the central position.

Trimming the rudder has no or little effect on the right wing dipping

And its like i said befor, if i was a spit pilot, and this was fixable i would land and tell my crew to bloody sort it out

It works 100% for me at stopping the right wing dropping.

Also certainly on the hurricane by default the rudder is trimmed slightly to the right ergo educing some RH role.

You do know you don’t need ailerons and can fly with the other 2 axis.

Only if you don't have to much yaw coupled roll, and generally only if you aren't to concerned about line of flight intersecting the earth. One of the Wright Brothers' big innovation was roll control, which was kind of important.

would that not be:
Only if you have enough yaw coupled roll, given "if you don't have to much yaw coupled roll" then you lack roll and have to much yaw

true its much easer the higher your wings are and the taller the rudder vs. the centreline/CoG.

don’t all flights intersecting the earth at some point?

regarding torque, the prop on in game spitfire & Hurricane turns clockwise (when viewed from the pilots orientation) therefore torque from the propellers resistance to the air its trying to pull the plane threw will try to make the plane role anticlockwise dropping the left wing (to every action there must be an opposite and equal reaction) after all torque must work both ways as it must push anticlockwise to push something else of an equal force clockwise.
