EMAX E3 Series 2306 2100kv Rainbow Limited Edition Brushless Motor
by EMAX

The EMAX E3 Series 2306 2100KV Rainbow Limited Edition Brushless Motor is a high-torque 5-inch FPV quadcopter motor engineered for pilots who demand sustained low-end power, smooth throttle resolution, and custom aesthetics. Featuring a multi-color rainbow anodized finish, this limited-edition variant pairs a 23mm stator diameter with a 6mm stator height to deliver increased torque and mid-throttle efficiency over standard 2207 stator profiles.

Built around a 12N14P stator framework and a 4mm hardened steel bearing shaft, the 2100KV configuration provides an ideal sweet spot for aggressive 4S setups or high-output 5S/6S freestyle and racing builds. Weighing under 32 grams, the motor incorporates low-resistance copper windings for efficient thermal dissipation under sustained loads, 120mm 20AWG silicone lead wires for clean solder installations, and standard 16x16mm mounting compatibility for 5" to 5.5" FPV drone frames.

Key Features

• Rainbow Limited Edition Finish: Features a custom multi-color anodized finish for a distinct look on custom 5-inch quadcopter builds.

• High-Torque 2306 Stator Profile: Wider 23mm stator delivers increased low-end punch and mid-throttle power for 5"–5.5" tri-blade propellers.

• 2100KV Performance Tuning: Balanced KV rating optimized for punchy 4S freestyle or high-speed 5S/6S FPV setups.

• 4mm Hardened Steel Shaft: Heavy-duty bearing shaft provides high impact resistance during aggressive flying and crashes.

• 12N14P Stator Architecture: Ensures smooth power delivery, reduced cogging, and precise flight controller throttle response.

• Clean Build Lead Length: Pre-soldered with 120mm 20AWG silicone wire leads for direct wiring to 4-in-1 ESCs.
