Pitch is the level of movement (up and down) of your RC helicopter. There are some RC helicopters that have good aerobatic capabilities but could also be difficult to fly and control due to the way these aircrafts are designed. If you want to talk about an RC helicopter's paddles and blades, you also need to consider its pitch because it is generally controlled by the position of the throttle on the remote transmitter.
Things You Will Need
- RC helicopter
- Extra flybar
- Sturdy rubber bands
- Pitch gauge
Locate the motors of your RC helicopter and start disconnecting its main and tail rotors. Look for the flybar (smaller bar) which sits on a horizontal position above the main rotors with the paddles attached to its ends then start leveling it in place. The paddles are the short-looking blades of your helicopter.
Turn the transmitter and radio receiver on your RC helicopter but avoid starting its motor. Start moving the stick of your throttle on the RC transmitter up to the midpoint level. Make the top line of the gauge parallel with the flybar by putting a pitch gauge through the center of the main rotor blade.
Adjust your RC helicopter's pitch by turning the control link. These are the metal poles that combine or connect the box looking rotor assembly on your RC blades. Mechanically alter or set your RC helicopter's pitch until the reading matches the recommended settings by its manufacturer.
Decrease the throttle control on your RC transmitter and turn it off. Look for the the battery of your RC helicopter's receiver and disconnect it. Remove the pitch gauge and spare flybar then detach the battery from the aircraft. Complete the set-up process by reattaching the motors to the blades.
An uneven pitch with a single bar providing more pitch than the other one can imbalance your RC helicopter's flight. The right amount of positive pitch makes the RC helicopter fly smoothly and evenly. Too little or too much pitch decreases your ability to successfully control the aircraft in flight.
Tips & Warnings
Flight controls allow hobbyists to control the collective and throttle which are generally linked together. Flight controls also allow hobbyists to control the cyclic controls known as pitch and roll, as well as the yaw, often referred as the tail rotor. The different kinds of helicopter controls are mainly carried out through the small servo motors, called as servos.
RC servos are remote control devices that hobbyists generally use to fly their toy aircrafts. These devices are usually manipulated via radio-controlled models and are mainly composed of an electric motor. A "piezoelectric gyroscope" is generally used on the yaw or tail rotor control to electronically adjust the control signal of the tail rotor servo.
The common RC helicopter's power sources are electric batteries, gas turbines, Nitro (nitro methane-methanol internal combustion), petrol and gasoline. Some hobbyists are now starting to collect for practical electric helicopters that are rapidly being manufactured and developed. If you start to search them online, they are becoming popular just like the nitro helicopters.
RC helicopter brushless motor engines connected or integrated with a high-performance lithium polymer battery are commonly used nowadays due to its price and practicality. RC helicopters engines usually have methanol power two stroke motors. You can also buy an RC helicopter that uses gasoline or has a jet turbine engine.
Electric helicopters are more practical to fly and collect compared to the expensive gas-turbine aircrafts. The high price of gas-turbine aircrafts generally make these flying toys unattainable to the common masses. RC helicopter hobbyists nowadays are usually looking for improved flight performance and affordability of prices.
