    The new KDE Direct 700XF-505-G3 High-Performance Brushless Motor is an extremely efficient and powerful motor for any 700 through 800-class single-rotor helicopter or fixed-wing application. Using the latest Computer-Aided Magnetic Field Analysis software to design the most efficient and optimized design for high-level, performance-driven flight applications and the highest-quality materials and processes in manufacturing; the new "G3" series is the new generation in performance for the single-rotor and UAS marketplace. 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) quad-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.

    Motors include 200°C, 10 AWG silicone-wire leads and ф6.5mm 24K Bullet Connectors (KDEXF-BC65pre-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.
