  • $114.95

Overview

Recommended ESC: KDE Direct UAS 35A+ HVC Multi-Rotor Series
Alternate ESC: KDE Direct UAS 55A+ Multi-Rotor Series

Recommended Propeller: KDE Direct 15.5" x 5.3 Triple-Propeller Blades

New production version includes laser-etch serialization (unique ID) and an active-centrifugal fan for improved cooling and sustained performance.

The new KDE Direct 4012XF-400 (D5) Multi-Rotor Brushless Motor is an extremely efficient and powerful motor for numerous multi-rotor and sUAS 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°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, 15 AWG, 760mm silicone-wire leads and ф3.5mm 24K Bullet Connectors (KDEXF-BC35pre-soldered to the motor leads and ESC matching 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.
