To fly radio
controlled helicopters is a constant balancing act.
R/C helicopters
are extremely unstable flying machines. So to fly R/C helicopters,
you constantly need to balance the helicopter to prevent it from
losing control and crash.
I'm going to
explain the controls for a 4-channel helicopter and upwards. One
channel is used to control a specific function on the helicopter.
You can fly the helicopter in the Normal Flight mode (only
applicable to four channel or less helicopters), or you can fly in
3D Flight mode for aerobatic maneuvers (only applicable to six or
more channel helicopters).
A four
cannel helicopter will have four functions.
1. Elevator
to control forward and backward flight. To go forward you need to
push the elevator stick forward. The nose of the helicopter will
pitch down. To go backwards you need to pull the elevator stick
down. The nose of the helicopter will pitch up.
2. Aileron
to control left or right roll. To bank left you need to move the
aileron stick left. The helicopter will roll to the left. To bank
right you need to move the aileron stick right. The helicopter will
roll to the right.
3. Rudder
to control left or right yaw. To turn the nose of the
helicopter left you need to move the rudder stick to the left. The
helicopter will yaw to the left. To turn the nose of the helicopter
right you need to move the rudder stick to the right. The helicopter
will yaw to the right.
4. Throttle
to control up and down. To go up you need to move the throttle
upwards. Take care that the throttle is close when you switch the
helicopter on. You always start with the throttle in the down or
closed position. The helicopter will start flying when the throttle
reaches 50% of throttle. To go further up you need to push the
throttle stick further than 50%. To go down you need to pull back on
the throttle stick.
Six channel
helicopters will have two more functions.
5. (CCPM)
Mixing of cyclic and collective. As throttle inputs increases in
the Normal Flight mode, the Cyclic Collective Pitch Mixing (CCPM)
system automatically adds pitch to the blades to help lift the
helicopter of the ground. The amount of pitch and how fast it is
added can affect the flight characteristics of the helicopter.
6. 3D mode
for aerobatic maneuvers. This function will be use when flying
aerobatics. This will enable you to fly the helicopter up side down.
Basically from 50% throttle and upward the pitch of the rotor blades
will increase with a positive angle of attack. From 50% throttle and
downward the pitch of the rotor blades will decrease with a negative
angle of attack.
