This is a Synergy Rail R-766 Flybarless Main Blade Set, designed for use with large 700 class electric helicopters. Rail blades were developed after extensive research from both flybarless electronics experts as well as aerodynamics experts. This research uncovered airfoil efficiencies that have been implemented in the design of Rail Blades and will provide improved performance that is noticeable in faster forward flight speed, more stable flight, cooler running power systems, as well as improved collective and cyclic response.
