KDE450XF-1750
-G2 Brushless Motor for 400/450-Class Electric Helicopter Series

(Patent Pending)
  • $92.95

Overview

The new KDE Direct 450XF-1750 High-Performance Brushless Motor is an extremely efficient and powerful motor for any 450-class Electronic helicopter, and was designed as a powerhouse for the ALIGN T-Rex 450 and GAUI X3 series helicopters. In collaboration with Castle Creations, the motor is custom designed for KDE Direct and used 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.

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).
