Infrared controlled helicopters can be controlled with an IR blaster connected to the 3.5 mm audio jack interface on a mobile device. [17] Another communications method used is Wi-Fi. The helicopter's built in computer creates its own wireless network, which the Wi-Fi enabled mobile device connects to and communicates with the helicopter. [18]
Helicopters with fly-by-wire systems allow a cyclic-style controller to be mounted to the side of the pilot seat. The cyclic is used to control the main rotor in order to change the helicopter's direction of movement. In a hover, the cyclic controls the movement of the helicopter forward, back, and laterally.
The CoAX 2D/2R was originally known as the FLIP 2 (Fly In Perfection) and is a derivative of the FLIP 1, a conventional helicopter with a main and tail rotor.[1]The CoAX 2D/2R was designed to comply with the European Class 6 microlight helicopter rules, including the category's maximum takeoff weight of 450 kg (992 lb).

Tandem-rotor helicopters, however, use counter-rotating rotors, with each cancelling out the other's torque. Therefore, all of the power from the engines can be used for lift, whereas a single-rotor helicopter uses some of the engine power to counter the torque. [1] An alternative is to mount two rotors in a coaxial configuration.
