DYS SUNFUN 2306 1750KV Brushless Motor CW Thread 5mm Shaft for 4-6S RC FPV Racing Drone and Multirotor - High-Performance 2306 Stator for 5-Inch and 6-Inch Propeller Builds
The DYS SUNFUN 2306 is a 1750KV brushless motor built on the 2306 stator platform with a 5mm CW-threaded shaft, designed for FPV racing drones and high-performance multirotor builds on 4-6S LiPo power systems where the 2306 stator geometry provides higher torque output and greater thermal mass than the more common 2207 format, making it the appropriate motor selection for 5-inch and 6-inch propeller builds that push motor loading beyond the thermal and torque limits of 2207-class motors under sustained full-throttle racing and aggressive freestyle conditions. The 2306 stator designation indicates a 22mm stator diameter and 6mm stator height, a stator geometry that trades the 1mm additional height of the 2207 format for a 1mm reduction in stator length while retaining the same 22mm diameter, resulting in a motor with a wider, flatter profile that distributes heat across a slightly larger stator surface area and reduces the motor's centre of gravity height above the frame - a characteristic that marginally improves the moment of inertia in the roll and pitch axes on flat FPV racing frames where motor height above the frame surface contributes to frame rotational inertia.
The 1750KV rating positions the SUNFUN 2306 in the 4S and 5S optimal operating band for 5-inch to 6-inch FPV propeller builds, delivering the RPM per volt characteristic that generates peak thrust efficiency on larger diameter, higher-pitch propellers at 4S and 5S voltage levels without the over-spinning and excessive current draw that would result from using a higher-KV motor at the same voltage and propeller combination. On 6S power, the 1750KV rating produces an absolute no-load RPM appropriate for experienced pilots who prefer the increased power ceiling and reduced current draw per watt of the 6S platform on 5-inch builds using lower-pitch propellers specifically selected for 6S motor and propeller pairing. The metal construction throughout the motor body, stator housing, and rotor bell provides the structural robustness required for sustained aggressive flying, propeller strike recovery, and high-vibration racing conditions where the mechanical stresses on the motor exceed the tolerance of lighter-weight hybrid construction alternatives. The 5mm CW-threaded shaft ensures secure propeller attachment using standard CW-thread propeller nuts across compatible propeller systems without requiring adapters or non-standard locking mechanisms.
