The SuperFlyer rides best when pressure is equally distributed between your front and back legs during flight.

Out of the box, start with the 0° spacer.

If there is too much front foot pressure, reduce tail wing angle by swapping out the 0° spacer for -1°. 

If there is too much back foot pressure, add tail wing angle by swapping out the 0° spacer for +1°.

Continue to fine-tune tail wing angle in 0.5° increments to find your optimum setting. The windier it is, the more you'll need to reduce tail wing angle to reduce power. The lighter the wind, the more you'll tend to add tail wing angle to boost power.
