RS2306 black


The RS2306 was designed to set a new standard of power and response for pilots seeking the ultimate in flight performance. With nearly twice the level of thrust of the original Red Bottom, the new RS2306 sets the bar even higher by pushing 2kg of thrust with 5045x3 propeller on 5S or 6045x3 on 4S.
Latest design language used in RS2205-S have been carried over to the RS2306. 
Lighter bell, hollowed steel shaft, bigger bearings, lower profile, and kept the overall diameter just 0.4mm wider than RS2205-S!

-2kg Thrust from a 2306 class motor!
-Larger Stator for smooth, responsive power.
-BEEFY 4mm Hardened and Tempered Hollow Steel Shaft: Breaking shafts are a thing of the past.
-0.15mm High Silicon-Steel Laminations: Higher volume of silicon increases electrical resistance in the lamination, reducing eddy-currents within the system (Translates electrical energy into mechanical energy more efficiently.). 
-High quality 4mm Inner Diamter Steel Ball Bearings.
-1.8mm N48SH Arc magnets (thinner and lighter which allow lower mass on the outer portion of the bell, resulting in faster acceleration. Less energy lost and more power delivered to the propeller).
-Special Edition Matte White Bell.
-Hex head bell fastener for easy servicing or bell replacement.
-PROPLOCK base for future performance-matched propellers: This anti-slip design locks in the propellers on to the motor to prevent Prop slippage during the hardest obstacle strikes.
-34 grams - Contrary to what most pilots say about motor weight Lighter is not always better. In this class of a motor that pushed 1,000s of grams of thrust, 34g is the absolute minimum without compromising structural integrity.

    Amazing amount of thrust

    Posted by Ryan on Sep 18th 2017

    These are significantly more powerful than the RS2205 motors. Coupled with the Avan props these things make any quad insanely fast. No matter how fast I'm headed for the ground, I know I only need a second to thrust out. It gives me a lot of confidence when flying. That said, they are amp hungry - My Tattu 1500mAh 75C batteries barely keep up. I have had some trouble with the motors getting warm and have been experimenting with filters in Betaflight to keep the temps down.

    EMAX does it again, just like the original red bottoms, this pushes the FPV scene even further - faster quads, more torque at lower throttle for those deep face-melting dives, durable and smooth. No wonder these barely stay in stock months after release.
