Ultrafly B-Series brushless, sensorless motors offer the ultimate in park flying and 3D flight performance at an affordable price. They weigh only 1.47 oz., but still produce enough torque to turn an 11" prop! More quiet and lightweight than other electric motors, B-Series motors feature a unique patented design that forces the magnet to hold its position when the prop stops suddenly at high RPM. This keyed-in magnet design also allows for easy maintenance. High-quality components, precision CNC tooling and high-performance bearings allow them to operate at higher RPM without vibration. Their gleaming chrome cases have large vent holes to help reduce weight and improve cooling. They're a perfect choice for flat foamies and other small 3D aerobats! B-Series motors deliver excellent acceleration for hovering and performing other extreme 3D aerobatic maneuvers. Requires a brushless, sensorless speed control and proper cooling to prevent overheating. No external motor mount is needed, which translates into even greater weight reduction.
