2 wheels vs 1 wheel in a linear shooter

Additional contact helps as does avoiding slippage but I think it is more about the relative rotation. The max velocity you can impart with one wheel is half the tangential velocity (because the frisbee is also rotating in proportion to the wheel's rotation and in the opposite direction). With two wheels you can approach the tangential velocity.

You want the firsbee to spin for stability so if using 2 wheels I think one might try running the two wheels at slightly different speeds.
