 This is the KDE Direct 450XF-3500 High Performance Brushless 450 Class Motor. The KDE Direct 450XF-3500 High-Performance Brushless Motor is an extremely efficient and powerful motor, and is the perfect compliment to the Align T-Rex 450 series helicopters, as well as other 450-class helicopters with M3x19mm or M2.5x16mm mounting profiles. Developed in collaboration with Castle Creations, the 450XF-3500 HP was custom designed for KDE Direct using the latest Computer-Aided Magnetic Field Analysis software to design the most efficient and optimized design for high-level, 3D-competition flight. The motor is designed to handle extreme-power setups and has been optimized for governor-control algorithms of the Castle Creations ESC product line; making this motor the most capable offering in the RC helicopter marketplace.
