6 new KDE Direct electric motors, KDE4012XF-400 for quadcopter, hexacopter or drone. They have never been used or installed, still in original box. You won't find a better quality motor then KDE. $750 for all six.
Description: The new KDE Direct 4012XF-400 (D5) Multi-Rotor Brushless Motor is an extremely efficient and powerful motor for numerous multi-rotor and heavy-lift applications, and was designed to bring high-quality and vibration-free motors to the market. The motors are designed with performance and durability in-mind, with features unseen in the current market: (1) high-grade, 240 deg-C continuous (340deg-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) triple-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.
