does the plane flight model mix control forces correctly ?

[^^artin]

e.g. when I hit Pitch and Roll together I got the impression the roll force is much to low (somehow Roll gets canceld out by the Pitch).

What do you think about this ?

Did you set your control surfaces to specific tasks (pitch/roll/yaw)?

Are your control surfaces at reasonable distances to the center of mass?

Do you have a flag picture of your craft?

[Streetwind]

There are things that can mess with control forces in ways you don't expect. For example, the large gimbal range on the new Panther engine can induce yaw forces during roll maneuvers if you're not careful with the placement of your rudders, engines and ailerons. (Perhaps someone better with planes than I can explain in more detail.)

A control surface has a certain maximum deflection. Suppose you have one pair of control surfaces at the back doing pitch and roll. Full pitch up = both control surfaces move up to their maximum deflection. Full roll right = left control surface down, right control surface up. Full pitch up AND full roll left = left control surface stays still, right control surface goes full up. You can see that the pitch and roll will be less when combined than when used separately.

Location on the plane matters. Roll will have the most effect inline with the CoM and out on the wing tips. Pitch will have the most effect far behind or far in front of the center of mass. Yaw of course needs to be on the vertical stabilizer. Make sure you right click each control surface and configure it.
