        • KDS CHASE 360 Series

    The new KDE Direct 450XF-1750 High-Performance Brushless Motor is an extremely efficient and powerful motor for any 450-class Electronic helicopter. Using the latest Computer-Aided Magnetic Field Analysis software to design the most efficient and optimized design for high-level, 3D-competition flight and the highest-quality materials and processes in manufacturing; the "G2" series sets the stage for the next level in performance for the RC helicopter marketplace. The motors are designed with performance and durability in-mind, with features unseen in the current market: (1) high-grade, 240°C continuous (340°C maximum) high-temperature solid-core copper windings for failure-free operation in extreme-climates, (2) Japanese-built, 0.2 mm silicon-steel stator laminations and Kevlar tie-wraps for high-efficiency performance, and (3) quad-bearing supported, ABEC-7 bearings for maintenance-free and worry-free flying for hundreds of hours. These are just a few of the advantages built-in to these motors, and every detail of the motors was scrutinized to produce the absolute best available; for a wide-range of flight applications.

    Motors include 200°C, 16 AWG silicone-wire leads and ф4.0mm 24k Bullet Connectors (pre-soldered to the motor leads and ESC bullets in the box).
