Recommended ESC: KDE Direct UAS 20A+ LV Multi-Rotor Series Thrust Generation: 1460g+ (6" x 4.5HQ Propeller, 4S Voltage) The new KDE2306XF-2550 establishes KDE Direct as the continued leader in FPV Racing performance and quality, with an optimized active-centrifugal fan for improved cooling and sustained performance, and new mounting schematic ideal for competition-level racing. Producing the same power output of a competitive 2208-class motor, but at a significantly lower weight and profile - the new design once again sets the benchmark in brushless motor technology. The new KDE Direct 2306XF-2550 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, 19 AWG, 250mm silicone-wire leads and ф3.5mm 24k Bullet Connectors (pre-soldered to the motor leads). Silicone-wire leads can be easily modified to length and soldered as needed (direct to ESC and/or bullet connectors).
