The AT Series includes long- and short-shaft BLDC motors designed for precision propulsion across indoor F3P aircraft, FPV wing racers, gliders, and large VTOL-class fixed-wing UAVs. The range covers 18 g to 2.6 kg in motor weight, producing between 360 g and 36 kg of static thrust, with aircraft compatibility from 0.3 kg up to approximately 55 kg takeoff weight. Housing sizes extend from Ø28.×16.5 mm to Ø110.6×119.8 mm, and supported LiPo power inputs range from 2S to 24S, allowing consistent scalability from small aerobatic airframes to heavy-lift unmanned platforms.
Core design strengths include hardened steel shafts for impact resistance, linear shaft and C-clip retention systems for safety under high rotation, and high-temperature arc magnets for sustained torque performance. Smaller motors deliver smooth response for 3D aerobatics and Spec Class FPV racing, while larger models incorporate dual or triple-bearing systems to maintain stability under heavy load. Higher-capacity variants in the AT series are engineered for 20–150 cc equivalent airframes, featuring enhanced thermal design, Japanese bearings, and precision-balanced rotors to ensure efficient, vibration-free power for advanced UAV integration.
