Parts
Name one part of a drone that helps it fly.
Motor, propeller, battery, frame
What does the motor do on the drone?
It spins the propeller to push air and create lift
What does a propeller do?
It pushes air down so the drone goes up.
Name one type of battery used in a small drone.
LiPo (Lithium Polymer)
Why should you remove propellers when testing motors on the bench?
To prevent injury or damage
What holds the motor and propeller on the drone?
Arm
What does "ESC" stand for?
Electronic System Controller
Which propeller make more lift: a small one or a big one?
A big one
If voltage up, do motors usually spin faster or slower?
Faster
Name two things you should check before every flight.
Propellers are tight, battery is charged, motors spin correctly, no loose wires.
Holds the part in place; keep motors spaced correctly; protects components; reduces vibration
True or False:
A motor that gets too hot is okay to keep using right away.
False
Why should propellers be balance?
Name one easy thing you can do to make a drones battery last longer last longer during a flight?
Fly gently-avoid fast, aggressive maneuvers, and rapid acceleration. Smooth flying uses less power and helps the battery last longer
What is one sign something is messed up during flight?
Excessive vibration, strange noises, sudden drift, smoke, or one motor not spinning correctly.
What connects the battery to the motor?
Power distribution board or wiring harness
Too large propeller, overloading, blocked airflow, damaged bearing
What happens is a propeller is the wrong size for the motor?
The motor may get too hot, draw too much current, and could fail or perform poorly.
Give one simple way to make the drone fly longer without changing the battery.
Reduce weight, fly more gently, use more efficient propellers
If a motor fails while flying, what should you do first?
Try to land safely without flying the drone over people.
Why is it important the parts are attached tightly before flying?
Loose parts can fall off; cause the drone to wobble, or make it crash
How can you check a motor is working before you fly?
Remove propellers, power on, give a short throttle test
What should you do if a propeller has a crack?
Replace it
What happens to the battery when you pull a lot of power quickly?
The battery voltage can drop and it can get hot faster.
Give one simple safety idea to protect people under a drone.
Use a safety zone
