Note: the new KDE Direct 1917H/1Y-N42 S2 High-Performance Brushless Motor is an extremely efficient and powerful
motor for any 700-sized Electronic helicopter, and was designed as a drop-in powerhouse for the KDE Direct ALIGN
TREX 700N E-Conversion components and is now leading the way in 90-class brushless motor developments
(perfectly suited for the TREX 700E).  In collaboration with Neumotors, the motor is custom designed for KDE Direct
and has an updated N42 magnet core, extremely low resistance windings, extended 41mm pinion shaft, easily
replaceable bearings, and other upgrades to make it extremely unique and powerful for sport and hard-3D flight.  The
motor is designed to handle extreme-power setups and has been optimized for governor-control algorithms of
common ESCs on the market; making this motor the most capable offering in the RC helicopter marketplace and is a
true testament to the quality of both KDE Direct and the Neumotors brand (made in USA!).
