Today, nearly all R/C helicopter use eCCPM. Most earlier helicopters used mechanical mixing. There have been two main types of systems to control the main rotors, mechanical mixing and electronic cyclic/collective pitch mixing (eCCPM). However, in the last 10 years, electric powered helicopters have matured to a point where power and flight times are better, but typically not as long as glow fuel helicopters. For the first 40 years, glow fuel helicopters were the most common type produced. Several deaths have occurred as recently as 2013.Д¬ommon power sources of remote control helicopters are glow fuel (also called nitro fuel, nitromethane- methanol), electric batteries, gasoline (petrol) and turbine engines.

Just like full sized helicopters, model helicopter rotors turn at high speeds and can cause severe injuries. Gasoline and jet turbine engines are also used. The engines typically used to be methanol-powered two-stroke motors, but electric brushless motors combined with a high-performance lithium polymer battery (LiPo) are now more common and provide improved efficiency, performance, and lifespan compared to brushed motors, while decreasing prices bring them within reach of hobbyists. Such 3-axis gyro is typically called a flybarless controller, so-called because it eliminates the need for a mechanical flybar. Most newer helicopters have gyro-stabilization on the other 2 axis of rotation ( pitch and roll) as well. A solid-state gyroscope sensor is typically used on the tail rotor ( yaw) control to counter wind- and torque-reaction-induced tail movement. The various helicopter controls are effected by means of small servo motors, commonly known as servos. Controlling these in unison enables the helicopter to perform the same maneuvers as full-sized helicopters, such as hovering and backwards flight, and many other maneuvers that full-sized helicopters cannot, such as inverted flight (where collective pitch control provides negative blade pitch to hold heli up inverted, and pitch/yaw controls must be reversed by pilot). ДЇlight controls allow pilots to control the collective (or throttle, on fixed pitch helicopters), the cyclic controls ( pitch and roll), and the tail rotor ( yaw). The more maneuverable designs are often harder to fly, but benefit from greater aerobatic capabilities.

Several basic designs of RC helicopters exist, of which some (such as those with collective pitch control) are more maneuverable than others. Note the size comparison with the cellular telephone at right.ДЄ radio-controlled helicopter (also RC helicopter) is model aircraft which is distinct from a RC airplane because of the differences in construction, aerodynamics, and flight training. This Heli-Max Axe Micro CX model helicopter is an example of a micro-sized coaxial model.
