How do you pitch a helicopter?

The collective pitch control is usually found at the pilot’s left hand; it is a lever that moves up and down to change the pitch angle of the main rotor blades. Raising or lowering the pitch control increases or decreases the pitch angle on all blades by the same amount.

What is collective pitch RC helicopter?

Collective Pitch RC Helicopters With collective pitch (CP), the pitch or angle of attack of the main rotor blades changes to control lift while the motor/engine speed and rotor speed stays more or less constant.

Is RC helicopters a good hobby?

From aerobatic 3D to scale, big turbine to small micro sizes, Collective pitch (CP) RC helicopters are the ultimate expression of fun & achievement in our hobby; they are what most people aspire towards. They are challenging and immensely rewarding; rarely will they ever get boring.

What is the pitch of a helicopter blade?

In aeronautics, blade pitch refers to the angle of the blades of an aircraft propeller or helicopter rotor. Blade pitch is measured relative to the aircraft body. It is usually described as “fine” or “low” for a more vertical blade angle, and “coarse” or “high” for a more horizontal blade angle.

What is pitch angle in helicopter?

operation of helicopters propeller, the rotor has a pitch angle, which is the angle between the horizontal plane of rotation of the rotor disc and the chord line of the airfoil. The pilot uses the collective and cyclic pitch control (see below) to vary this pitch angle.

Are bigger RC helicopters easier to fly?

Wind won’t affect large RC helicopters as much – again more stability. Large RC helicopters are easier to see while flying. Large RC helicopters are easier to work on.

How does a collective pitch RC helicopter work?

RC Helicopters. How Collective Pitch RC Helicopters Work. In a collective pitch model, the angle of attack or pitch of the rotor blades can be adjusted to control the lift of the helicopter while the engine/electric motor speed as well as the rotor speed remains constant.

How does pitch and throttle affect a helicopter?

Remember as the throttle stick moves we are going through two curves, pitch and throttle. Both have an effect on lift, but our pitch values are fixed, so the throttle values are the ones that need “tweaking” in order to maintain the correct headspeed of the helicopter.

What makes a RC helicopter able to fly?

The main rotor produces a lifting force that enables the helicopter to fly. The rotor blades on most RC helicopters have the airfoil shape of an airplane’s wing. But they are narrower and thinner. As these blades rotate in the air, the change in air pressure above and below the wing generates a lifting force.

Where is the swash plate on a RC helicopter?

RC Helicopters. The Swash Plate Assembly: This is used to turn the pilot’s commands into the required motion of the rotor blades or fly-bar. This component fits on the rotor shaft underneath the hand of the rotor and has a non-rotating and rotating disc.
