At first glance, a drone might look like just a small flying machine with propellers — but inside, it’s a miniature marvel of engineering!

Every time you press “take off,” a series of electrical and mechanical systems start working together:

• The battery powers up the system.

• The motors spin the propellers.

• The ESCs control motor speed.

• The flight controller decides how to keep balance.

• And the GPS module helps the drone know where it is.

Just like your body has organs with different functions, a drone has electronic “organs” that make it think, move, and respond.
