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)
  • KV Options: 1600KV (6–8S), 1700KV (3–6S), 1900KV (3–6S), 2400KV (3–4S)
  • Max Power: Up to 1310W (KV1600 on 6S)
  • Peak Current: 41A–50A depending on KV variant
  • 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.

Flight Controller / VTX Warranty Policy
 
At weBLEEDfpv, we are committed to providing high-quality products. However, due to the technical nature of flight controllers and VTX's the precision required for installation, our warranty policy for flight controllers is as follows:
 
1. No Warranty Post-Soldering: 
   Once any soldering has been performed on the flight controller / VTX's, we are no longer responsible for replacements, repairs, or refunds. The process of soldering can introduce various factors that may lead to damage, and we are unable to control or verify the conditions in which the soldering was conducted.
   
2. Pre-Soldering Inspection: 
   Before you begin soldering, we recommend carefully inspecting the flight controller  / VTX's for any potential issues. If any defects or issues are found prior to soldering, please contact us immediately for a replacement.
 
3. User Responsibility: 
   Soldering requires skill and experience, and improper techniques may result in damage to the flight controller, including but not limited to overheating or lifting solder pads. Please ensure you are confident in your soldering abilities before proceeding, as we cannot be held liable for any damages caused during installation.
 
4. Final Sale: 
   All flight controller sales are final once the product has been modified or soldered. We are unable to offer returns or exchanges on used or modified products.

⚠️ FPV DIGITAL SYSTEM NOTICE

HDZero, Walksnail, VTX systems, and ultra-micro FPV electronics generate heat quickly while powered and require proper handling during setup and troubleshooting.

Bench setup without airflow/cooling can result in excessive heat buildup.

Once powered, configured, firmware updated, soldered, flown, or modified, products are considered used.

Manufacturer warranty may apply for BNF drones and electronic systems.
