Replacement Parts:

The new KDE Direct 13218XF-120 (HE) Multi-Rotor Brushless Motor is an aerospace-level flagship of technology from KDE Direct - designed specifically for heavy-lift commercial and industrial applications.  With an all-new bearing design (triple-supported, ABEC-7 angular-contact and radial bearings) specific for high-thrust capacity and market-leading durability, the motors encompass the premier of UAS technology.  The motor incorporates a very high-efficiency (HE) 42-pole design, used in our industrial applications, and now brought to the UAS market for long-duration flight performance.  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) integrated centrifugal-fan for cool running temperatures and high-performance capacity.  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.

Motor includes 200°C, 10 AWG, 760mm silicone-wire leads and ф4.0mm 24K Bullet Connectors (KDEXF-BC40, pre-soldered to the motor leads and ESC matching Bullet Connectors).
