Does a SIG Fourstar 60 have a lot of roll coupling?
The wings were clipped one rib bay each side.
I would guess that it has less yaw-roll coupling than a high wing trainer but more than a competition pattern plane.
Yaw-roll coupling is not nessesarily a bad thing. Trainers have a lot of it on purpose, it's a major contributer to a trainer's stability. Planes like the Fourstars are designed to be a step up from trainers so they likely still have a little yaw-roll coupling.
