    Replacement Parts:

    The new KDE Direct 2315XF-2050 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, 18 AWG, 255mm silicone-wire leads and ф3.5mm 24K Bullet Connectors (KDEXF-BC35pre-soldered to the motor leads and ESC matching Bullet Connectors).  Motors are rotational-direction matched and color-coded (black/red/blue) for simple installation into a wide-variety of airframes.  Silicone-wire leads can be easily modified to length and soldered as needed (direct to ESC and/or bullet connectors).
