Starting a new class of helicopters by incorporating the use of blade sizes up to 640mm allows 700 class flight characteristics in a smaller, more affordable package.
Century Helicopter Products has filled the gap between the 600 and 700 size. By offering better fuel economy the Radikal N640 provides the power to keep up with the big boys. Without having to take that giant leap to a 700 class helicopter, the pilot can now enjoy the presence of a larger helicopter at a more affordable entry fee.
