The Importance of Understanding RC Helicopter Fuselage
The world of RC or radio-controlled
helicopters is a rich and exciting one, but you would be surprised at how many newcomers do not realize how
important an RC helicopter fuselage really is. In fact, people coming into this hobby do not always even
know what the
fuselage is! In truth, it is a surprisingly simple concept, and we are going to discuss not only why it is so
important but also what all you need to know about it.
Now, the fuselage
itself is actually the body of the helicopter, or of a plane and it is the primary part of the same. It includes
not only the tail, but just about everything else as well. There is one exception. A “flying wing” type of
aircraft does not require a separate fuselage. Helicopters do, however.
The fuselage is very
important when it comes to yaw control. Specifically, the left and right controls are used along with the
helicopter's torque. The spinning of the primary rotors create this force. The first instinct of the fuselage, in
response to the way the blades spin, will be to spin very fast, but in the opposite direction. You cannot have an
equal amount of thrust and torque, or else the fuselage of the helicopter will not spin around at all. When you
have more thrust than torque, then the fuselage will yaw in one direction. It will yaw in the other direction when
there is less thrust than torque.
Due to the
relationships between thrust, torque, and fuselage, you can understand why it is important to pay attention to how
you are powering your RC helicopter. One wrong part, one wrong move, and you will find yourself with a helicopter
that will not fly.
