Lesson 2: Throttle
You've taken off and landed! Now you can start to expand your horizons and skills as you learn to raise and lower the VEX AIR Drone using throttle.
Watch this video to learn about:
- How to use the left joystick to throttle up and down.
- How to change the maximum Z Height of the drone.
- How to switch camera views to see the drone's position and movement from different perspectives.
Hover & Discover
Throttle is the control that the pilot uses to change the power to the motors, which affects how fast the drone’s propellers spin. When you increase throttle, the propellers spin faster and push more air downward.
Lift is the result of that action—it’s the upward force created by the spinning propellers pushing air down. If lift becomes stronger than gravity, the drone rises; if it’s weaker, the drone descends.
To summarize: throttle is what you do to control the drone, and lift is what happens because of those controls.
Mission: Throttle Up and Down
Real-World Connections

Professional drone operators also set their own height limits when flying near buildings, trees, or power lines. Controlling altitude keeps drones visible, stable, and safe—both for the pilot and for everything (and everyone) below.

Flying with the VEX AIR Drone in a classroom means that you will also need to consider the maximum Z Height on the controller in relation to your space. You will learn more about this specific safety consideration in the following course.
