Multirotors & RC

MultiCopters are aerodynamically unstable and absolutely require an onboard computer (aka flight controller) for stable flight. As a result, they are “Fly by Wire” systems and if the computer isn’t working, you aren’t flying. The flight controller combines data from small onboard MEMs gyroscopes, accelerometers (the same as those found in smart phones) to maintain an accurate estimate of its orientation and position.


A quadcopter can control its roll and pitch rotation by speeding up two motors on one side and slowing down the other two. So for example, if the quadcopter wanted to roll left it would speed up motors on the right side of the frame and slow down the two on the left. Similarly, if it wants to rotate forward it speeds up the back two motors and slows down the front two.


The copter can turn (aka “yaw”) left or right by speeding up two motors that are diagonal across from each other and slowing down the other two.

Horizontal motion is accomplished by temporarily speeding up/slowing down some motors so that the vehicle is leaning in the direction of desired travel and increasing the overall thrust of all motors so the vehicle shoots forward. Generally the more the vehicle leans, the faster it travels. Altitude is controlled by speeding up or slowing down all motors at the same time.
