NO DOORS TAKEOFF! Airbus H125, H145 D3, Robinson R66 & Agusta A109 Start-Up

This video begins with the Airbus H125 performing a takeoff in an open configuration with the doors removed, commonly used for sightseeing and aerial filming. Powered by a Safran Arriel 2D engine, it has a maximum takeoff weight of 2,370 kg (5,225 lbs), a top speed of 155 knots, and a range of around 340 nautical miles. The reduced weight and drag, combined with its strong power-to-weight ratio, allow for a responsive lift-off and stable hover, even in this open-door setup. Next is the Airbus H145 D3, a twin-engine helicopter equipped with two Safran Arriel 2E engines and a five-blade main rotor. It supports a maximum takeoff weight of 3,800 kg (8,377 lbs) and cruises at around 145 knots. The additional blade improves lift efficiency and reduces vibration, which is noticeable during its controlled approach and stable hover. The Robinson R66 follows, powered by a Rolls-Royce RR300 turbine engine. It has a maximum takeoff weight of 1,225 kg (2,700 lbs), a cruise speed of about 110–120 knots, and a range near 350 nautical miles. Its lightweight structure and low rotor inertia result in quick throttle response and efficient takeoff performance. The sequence ends with the Agusta A109, shown during its start-up and takeoff. Powered by twin Pratt & Whitney engines, it supports a maximum takeoff weight of around 3,175 kg (7,000 lbs) and cruises at up to 156 knots. The start-up sequence includes engine spool-up and rotor engagement, followed by a smooth transition into hover and a controlled takeoff, demonstrating its high power-to-weight ratio and precise handling.
