Yes. As I said in a different post, there are subtle aerodynamic effects
that can be used to affect the exact flight path of the frisbee. Release
attitude (pitch and roll), initial flight path, rotation speed, even
impact (intentional or otherwise ) with some object or surface
mid-flight, these all have small-but-interesting-and-useful effects on the
exact course the frisbee follows.

A large factor is also the gyroscopic affects (effects?) resulting from the
change in plane of rotation, like the spinning bicycle wheel being held by
the person on the turntable.

That is why (for a right handed person, throwing with the standard clockwise
rotation) the release position for a straight throw, is with the side
opposite from the hand to be held lower than the side the hand is holding.
