    Replacement Parts:

    The new KDE Direct 1806XF-2350 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, 20 AWG, 200mm silicone-wire leads and ф3.5mm 24K Bullet Connectors (KDEXF-BC35pre-soldered to the motor leads and ESC matching Bullet Connectors).  Silicone-wire leads can be easily modified to length and soldered as needed (direct to ESC and/or bullet connectors).

    *: Brushless motor requires consistent open airflow (5 mph or greater) across the windings to maintain maximum continuous current and power ratings during operation. Performance figures are provided as guidelines for normal conditions and operation; environmental factors, such as air temperature and humidity, can significantly alter the maximum performance limits of the motor.
