Using the Wing Test Stand
1. After the wing is placed on the stand, hold down the ON/ZERO
button to turn the digital scale on (Figure 3). Before you take
measurements, make sure the scale is tared. The display should
show “0.0.” If it does not, press the ON/ZERO button again.
2. To change measurements between g and oz, press the UNIT
button (Figure 4).
3. Set the angle for testing your wing and place a fan in front of the
Wing Test Stand (Figure 5). Turn on the fan. The number in the

Activity Ideas
• Leave the designed wing in a stable position and change the fan
speed. Measure the lift. Compare with dierent speeds.
• Leave the fan speed at a set amount and change the wing angle.
Discuss what happens to the lift.
• Determine the stall angle of the wing. As you increase the angle
of attack, there will be a drop-o in lift. That will be the stall angle.
Discuss why this happens.
• Try many dierent wing designs with the Wing Test Stand.
