Robinson Helicopters has doubled annual production of its R44 single turbine helicopter, after the surge in orders for its new hydraulic-controlled variant, the Raven, which entered service in April. To reduce the six-month backlog, production has increased from three to five aircraft a week. A ramp-up to six aircraft is planned next month. Robinson was the top-selling helicopter manufacturer last year in terms of units sold, delivering 278 helicopters.
