For example, a helicopter with a 0.30 cu in (4.9 cm 3) engine was a 30 class and a helicopter with a 0.90 cu in (14.7 cm 3) engine was referred to as a 90 class helicopter. The bigger and more powerful the engine, the larger the main rotor blade that it can turn and hence the bigger the aircraft overall.
Weighing a mere 10 grams, the Picoo Z measures 170 mm long, and has a main rotor span of 130 mm. The helicopter is controlled by a 3-frequency a-b-c infrared controller, with two channels (one for the main rotor and one for the tail rotor) allowing independent user control of throttle (main rotor RPM) and tail rotor RPM.
It is important that each aircraft uses a different channel, otherwise interference could result. For example, if a person is flying an aircraft on channel 35 (used for 72.490 MHz in North America), and someone else turns their radio on the same channel, the aircraft's control will be compromised and the result is almost always a crash.
The Helicycle helicopter is the first experimental helicopter kit in mass-production to be powered by a turbine engine, the military surplus Solar T62-T32, capable of producing 150 shaft horsepower. The engine is limited to 95 horsepower due to torque limits on the main gearbox and rotor system.
The Yamaha R-MAX is a Japanese unmanned helicopter developed by the Yamaha Motor Company in the 1990s. The gasoline-powered aircraft has a two-bladed rotor and is remote-controlled by a line-of-sight user. It was designed primarily for agricultural use, and is capable of precise aerial spraying of crops.
