*With heating and demisting turned on, power is limited to 97.5% when OAT is between 0-10 degs C and PA is over 15000 feet.
You can start and stop rotors in winds up to 40 kts from any direction, and 50 kt headwinds. You can hover in winds up to 17 kts from any direction, and possibly more— up to 30 kts at MAUW has been proven.
Overall length 12.94 m (42.45 ft).

Engine

A Turbomeca Arriel 1D (1B in a BA, and a 1D1 in a B2) free turbine engine aft of the main gearbox, which is around 102 lbs heavier than the JetRanger engine at 240-260 lbs, depending on the version. It consists of a single-stage axial and a centrifugal compressor, an annular combustion chamber with centrifugal fuel injection and ignition, a two-stage axial turbine to drive the compressors and a single-stage free power turbine. It has self-contained lubrication with external oil cooling system and oil tank.

Rotors
The Starflex semi-rigid main rotor head is made from resin glass fibre, laminated thrust bearings and self-lubricating bearings. The rotors, which are made of glass-resin laminate, go round clockwise when viewed from above. Pitch variation is achieved through distortion of elastomer items. There is a vibration dampening device in the centre of the rotor head, which consists of a weight oscillating between three springs 120° apart.
A horn sounds when speed drops below 360 RPM in the B1 (335 in the B). The maximum RPM speed for the rotor brake is 170 RPM in heavy winds (140 in light), with at least 5 minutes between actuations.
The swashplate is operated by three mobile cylinder servo controls (two lateral, one fore-and-aft) whose piston rod is integral with the MGB. Control movements are transmitted to the starflex, which bends to control rotor pitch.
One operating tip concerns protecting the starflex when on sloping ground. Once both skids are down, centralise the cyclic, as the machine will be going nowhere and any strain is reflected in the starflex. It doesn’t give you any immediate benefit, but will be reflected in maintenance costs.

Tail Rotors
Two-bladed, see-saw mounted on the tail rotor gearbox. They rotate anticlockwise as viewed from the right, so are pushers. Be aware that overstuffing the rear baggage compartment can affect the controls as they are routed just above the compartment.
The extra bit of metal along the trailing edges of the blades is just to make the B model's tail rotors able to work on the BA, B@, etc. (it saves designing new ones). However, they must be checked for cracks every 10 hours at the ends.

Rotor Brake
When the lever is forward, the rotor brake is released. When applied, the lever causes a diaphragm spring to compress, which keeps the friction linings under constant load.
