KDE direct comes up with a series of motors that are truly effective and serves the purpose.

The new KDE Direct 2814XF-515 Multi-Rotor Brushless Motor is an extremely efficient and powerful motor for numerous multi-rotor and sUAS 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°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) 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.

Motor includes 200°C, 17 AWG, 635mm silicone-wire leads and ф3.5mm 24k Bullet Connectors (pre-soldered to the motor leads and ESC female bullets included).

Models: Universal mounting pattern provides simple installation for a wide-range of multi-rotor and sUAS applications: M3 x ф25mm, M3 x ф19mm, M2.5 x ф19mm.
