A view of the EC120B's tailboom and Fenestron anti-torque tail fan. A Fenestron (sometimes alternatively referred to as a fantail or a "fan-in-fin" arrangement [1]) is an enclosed helicopter tail rotor that operates like a ducted fan.
The EC130 is a single-engine helicopter. It uses a three-bladed Starflex main rotor which is matched to an enclosed tail fan anti-torque device, known as a Fenestron, the latter feature replacing the traditional tail rotor found on the older AS350. The Fenestron has unevenly spaced blades to reduce noise generation by 50% compared to a ...
The K1-S19 was designed to comply with the European Class 6 microlight helicopter rules and it's certified as ultralight helicopter MTOW 600Kg. It features a single main rotor and tail rotor, a two-seats-in side-by-side configuration enclosed cockpit with a windshield, skid landing gear and a 250 hp (186 kW) Konner TK-250 turboshaft engine.

The R44 is a single-engined helicopter with a semi-rigid two-bladed main rotor, a two-bladed tail rotor and a skid landing gear. It has an enclosed cabin with two rows of side-by-side seating for a pilot and three passengers. Tail rotor direction of rotation on the R44 is reversed compared to the R22 for improved yaw control authority.
The tail rotor is powered by the helicopter's main power plant, and rotates at a speed proportional to that of the main rotor. In both piston and turbine powered helicopters, the main rotor and the tail rotor are mechanically connected through a freewheeling clutch system , which allows the rotors to keep turning in the event of an engine ...
The tail rotor is a smaller rotor mounted so that it rotates vertically or near-vertically at the end of the tail of a traditional single-rotor helicopter. The tail rotor's position and distance from the center of gravity allow it to develop thrust in a direction opposite that of the main rotor's rotation, thereby countering the torque effect ...
It features a single main rotor and tail rotor, a two-seats-in side-by-side configuration enclosed cockpit with a bubble canopy, skid landing gear and a four-cylinder, liquid and air-cooled, four stroke 100 hp (75 kW) Rotax 912ULS engine, a Dynali-developed fuel-injected 110 hp (82 kW) conversion Rotax 912ULS-1 engine or a 115 hp (86 kW ...
The CH77 Ranabot was designed to comply with the European Class 6 microlight helicopter rules. It features a single main rotor and tail rotor, a single-seat, a two-seats-in side-by-side configuration enclosed cockpit, skid landing gear and an EPA Power-modified four-cylinder, liquid and air-cooled, four stroke 130 hp (97 kW) Rotax 914 engine.
