Flying RC helicopters is a rewarding yet challenging experience. These toy birds are gaining popularity in Australia as they are easily accessible for people and easy to fly at an affordable price. In this mini-manual, you will learn how to operate these vehicles and find out why RC Helicopters in Australia are becoming more popular.
- What are RC Helicopters?
Remote controlled helicopters are small versions of real helicopters which operate almost the same as the real ones. There are miniature chinooks, avatar jet fighters, even UFO-inspired helis. They differ in size and of course, RC helis are operated through a remote control. Toy helis have flybars which is responsible for their flight stability. However, the latest models of RC helis now no longer use flybar for stabilization which makes them closer to the design of real helicopters.
- How DO RC Helicopters Fly?
If you are familiar with aircraft and flight, you will have an idea of how RC helis fly. Once the rotor blades rotate, it creates lift. For the single blade helicopters, however, the body is being steered by the tail rotor blade. By increasing the speed of the rotor blades, you increase lift, thereby defying gravity – then it flies. To sustain hover, the lift force must equal the force of gravity. To descend, the lift force has to be less than the pull of gravity then gravity will pull it down.
- Components of an RC Helicopter
- Motor – turns the gears consequently turning the central rotors
- Electric Speed Controller (ESC) – part of the helis responsible for power dissemination for all the other parts
- Servo – responsible for switching the mechanical components of the aircraft
- Gyro – maniouated the tail rotor servo to balance the torque reaction
- Batteries – enable aircraft to move by serving as its power source
- Radio – enables the pilot to control the aircraft by permitting signal transmission to recieve commands
- Receiver – accepts the transmitted signals from the pilot’s instructions with the use of radio which enables the helicopter to move according to commands
- RC Helicopter channels
Channels indicate the number of control functions of the heli. There are four types of helicoper channels:
** 2 Channel Helicopters – can fly in two channels -up/down; yaw left/yaw right
** 3 channel Helicopters – can fly in 3 channels – up/down; yaw left/yaw right; forward/backwards
** 4 channel helicopters – can fly in 4 channels – p/down; yaw left/yaw right; forward/backwards; roll left/roll right
** 6 channel helicopters – can do all of the above plus they have the ability to fly upside down, commonly known as full 3D flight.
- Coaxial Helicopters – These helis have 2 sets of blades spinning in opposite direction both creating lift. These are extremely stable helis which is great for beginners and children.
- Single blade Helicopters – These look like real-life helicopters with just one set of blades and a tail rotor. They move faster than coaxials and some models can perform aerobatics. Single blade helis are suitable for those who have flown a coaxial before.
- Quadcopters – Also known as drones, quadcopters have 4 blades joined by a center piece or body. They are extremely stable and fast and can be used indoors or outdoors. These helis are suitable for intermediates.
As time “flies by”, pardon the pun, you will become more familiar with the RC helicopters available in Australia and sooner or later, be an expert yourself. Cheers!
