This document provides an overview of remote control helicopters, including their different types, parts, control methods, and flight techniques. It discusses the main rotor system parts like blades, hub, and mast. It explains the swash plate and how the collective, cyclic, and anti-torque controls are used to manage lift, direction, and torque. Precise hovering requires continuously adjusting the cyclic, collective and pedal inputs. Setting with power is one of the most dangerous flight situations for a helicopter pilot.

1. RC Helicopter
-A super fun and rewarding hobby
for all ages….

2. Content:-
• What is RC Helicopter?
• It’s different forms
• Various parts
• Control and theory
• Gyroscopic precision
• Settling with power

3. Types:
• Quad
• Single rotor
• Nitro gas

4. Helicopter

5. Parts

7. Main Rotor System
• Root: The inner end of the blade where the rotors connect
to the blade.
• Blade Grips: Large attaching points where the rotor blade
connects to the hub.
• Hub: Sits atop the mast, and connects the rotor blades to
the control tubes.
• Mast: Rotating shaft from the transmission, which
connects the rotor blades to the helicopter.
• Control Tubes: Push Pull tubes that change the pitch of
the rotor blades.
• Pitch: Increased or decreased angle of the rotor blades to
raise, lower, or change the direction of the rotors thrust
force.
• Jesus Nut: Is the singular nut that holds the hub onto the
mast. (If it fails, the next person you see will be Jesus).

8. Control and Theory
• Ccpm
• 3 basic areas-
Lift and collective control
Direction and cyclic control
Torque and tail rotor control

9. Swash plate

10. Collective-up and down
It puts a collective control input into the rotor system, meaning
that it puts either "all up", or "all down" control inputs in at one
time through the swash plate.

11. Cyclic-left and right
The cyclic changes the angle of attack of the
main rotor's wings unevenly by tilting the
swash plate assembly. On one side of the
helicopter, the angle of attack (and
therefore the lift) is greater.

12. Anti-torque
to control the
direction in which the
nose of the aircraft is
pointed

13. Gyroscopic precision
By increasing pitch on
one half of the rotor disc
and decreasing it on the
opposite half, the rotor
will want to tilt. Seeing
that the rotor is firmly
attached to the helicopter
– the heli will follow along
and also tilt in e same
direction.

14. HOVER…
• Most challenging aspect of pilot’s flight
• Helicopters-generally dynamically unstable…
• Inputs and corrections to be made by pilot..
• Control inputs-cyclic, collective and pedal…
• Adjustment in any one requires adjustment of
other two…makes hover difficult..

15. Setting with power
•Most dangerous situation a pilot may face….
•Must avoid 3 conditions –
•A near zero airspeed..
•100% power applied…
•A better than 300 foot per minute rate of descent…
