EMAX brushless motors are suitable for a wide range of hobby, engineering, and custom motion-control applications. They're ideal for high-speed propulsion, precision motion control, custom cooling fans, gimbals, 3D-printed mechanisms, and STEM or engineering prototypes.
If you're building lightweight, high-efficiency systems that need reliable power, smooth operation, and long service life, EMAX brushless motors are the go-to solution.
EMAX E3 Series 2306 Brushless Motor — High-Torque FPV Motor for 5" Builds
The EMAX E3 Series 2306 Rainbow Limited Edition Brushless Motor is a high-torque 2306 FPV motor purpose-built for pilots who demand more low-end grunt and sustained power. With a wider 23mm stator diameter and 6mm height advantage over the 2207, the 2306 delivers increased torque and improved efficiency at mid-throttle — making it a standout choice for 5" freestyle builds, cinematic FPV quads, and long-range cruisers.
Available in KV1600, KV1700, KV1900, and KV2400 configurations across 3S–8S LiPo setups, the E3 2306 runs a 12N14P stator with a 4mm hardened steel shaft and is optimized for 5"–5.5" propellers. The lightweight ~31.5–31.9g build (without wire) and low internal resistance (48–85mΩ) ensure excellent thermal management and consistent power output under sustained load.
Key Features
Motor Size: 2306 (wider stator for increased torque vs. 2207)
Stator: 12N14P for smooth, efficient power delivery
Shaft: 4mm hardened steel bearing shaft
Wire: 20AWG 120mm leads for clean builds
Weight: ~31.5–31.9g (without silicone wire)
Rainbow Limited Edition anodized finish for a premium aesthetic
2306 vs. 2207 — Which Should You Choose?
The 2306 stator is wider than the 2207, producing more torque at lower RPMs — ideal for heavier props, cinematic flying, or builds where mid-throttle efficiency matters more than top-end speed. If you're running 5" tri-blades or want a smoother, punchier feel, the 2306 is the better pick.
Compatible With
5" and 5.5" propellers, 3S–8S LiPo batteries (KV-dependent), standard 16×16mm and 30.5×30.5mm motor mount patterns on most FPV frames.
Why Choose the EMAX E3 2306?
EMAX's precision manufacturing and consistent quality make the E3 Series a trusted choice across the FPV community. The 2306 Rainbow Limited Edition combines performance-tuned internals with a striking anodized finish — a motor that performs as good as it looks. Whether you're building a smooth cinematic rig or a hard-hitting freestyle quad, the E3 2306 delivers.
