Overview
About EMAX RS2306 2400KV Brushless Motor.
The EMAX RS2306 2400KV is a 2306-class RaceSpec brushless motor that sits in the sweet spot for high-performance 5-inch FPV quadcopters. The larger 23mm-diameter, ~6mm-tall stator (12N14P) carries more copper and bigger magnets than a 2205 motor, giving it noticeably more torque and the ability to drive heavier, higher-pitch 5-inch propellers without bogging down — ideal for power-hungry racing and aggressive freestyle on 3S-4S packs.
EMAX builds the RS2306 around a hardened hollow steel shaft, a tight magnet-to-stator air gap and a 5mm threaded prop mount, with the larger stator delivering smooth, responsive power delivery and strong mid-to-top-end pull. The motor is supplied with a defined thread direction (CW versions are common) and is intended to be bought as a balanced set of four for a complete quad.
This motor targets serious FPV racers and freestyle pilots who want more grunt than a 2205 can provide, as well as builders running heavier 5-inch rigs, HD camera quads or cinematic freestyle frames. At 2400KV it is well matched to 4S with mid-pitch props, producing strong per-motor thrust while keeping a competitive power-to-weight ratio for the 2306 size class.
Key features
Why it stands out.
2400KV winding pairs well with 4S and mid-pitch 5-inch props for high thrust and crisp throttle response.
Hardened hollow steel shaft and tight magnet-to-stator air gap support smooth, responsive power delivery.
5mm threaded prop mount accepts standard 5-inch FPV propellers for fast, secure prop changes.
RaceSpec build suited to demanding racing, freestyle and heavier HD/cinematic 5-inch quad setups.

Buying guide
How to choose.
Pick the RS2306 over a 2205 when you want more torque to swing heavier or higher-pitch 5-inch props, or when your quad is on the heavier side (HD camera, bigger battery). The 2400KV winding is a strong all-round choice on 4S; if you fly 6S you would typically drop to a lower-KV 2306/2207 to keep current and heat in check. Buy a matched set of four with the correct CW/CCW thread layout.
Because a 2306 at 2400KV can pull high peak current under load, fit BLHeli_S or BLHeli_32 ESCs with comfortable headroom — many 5-inch builders run 35A-class or higher per motor. Confirm your propeller pitch and weight target before committing: lighter, lower-pitch props maximise response and efficiency, while heavier props extract the motor's full thrust at the cost of current draw and temperature.
For India buyers, check whether the listing is the single motor or a set, verify thread direction (CW/CCW) and lead style, and order a spare since race-class motors are wear items. Confirm the exact KV variant, as the RS2306 family is sold in several KV options.
FAQ
Common questions.
How is the RS2306 different from the RS2205?
The RS2306 uses a larger, taller 23mm stator than the 2205's 22x5mm stator, so it holds more copper and bigger magnets. That gives more torque and lets it drive heavier or higher-pitch 5-inch props, at the cost of slightly more weight.
What battery is best with the 2400KV version?
The 2400KV winding is designed for 3S-4S and is best matched to 4S for strong thrust without overspeeding. For 6S builds, choose a lower-KV RS2306 variant to keep current draw and motor temperatures under control.
What propellers should I run?
It takes standard 5-inch FPV props via the 5mm threaded mount. The extra torque of the 2306 suits mid-pitch tri-blade props on 4S; lighter low-pitch props maximise response and efficiency if you prefer.
Is it available in CW and CCW?
Yes, the RS2306 is offered with both thread directions. Build a quad with two CW and two CCW motors so the prop nuts self-tighten in flight and rotation matches your flight controller mapping.
What ESC do I need for this motor?
Use a BLHeli_S or BLHeli_32 ESC rated above your measured peak current. Many 5-inch builders running 2306 motors on 4S choose 35A-class or higher ESCs per motor for thermal and electrical headroom.
How much does each motor weigh?
Each RS2306 weighs roughly 34g, slightly heavier than a 2205 due to the larger stator. The added torque generally outweighs the small weight penalty on power-oriented 5-inch builds.
