Medusa Research is proud to introduce the Afterburner V2 Series of high efficiency brushless motors.

Through the combination of metallurgically advanced ultra low loss lamination steel, computer designed stator, and vented case these motors have unrivaled performance.

                     

The new Afterburner V2 Series of motors offers increased Efficiency, more Power, and  better Performance.

                     

The Afterburner V2 Series brushless motors will outperform other In-runners as well as Out-runners in direct drive and geared applications.

Higher Efficiency with Venting means:

l Cooler Motor Temperature for consistent performance,

l Longer Flight times,

l More Output Power.

         

Higher Quality components:

l Ultra Low loss lamination steel,

l Hardened Stainless Steel Shaft

l ABEC 5 Bearings

(unlike most other motors that use the lower rated ABEC 1)


We use Quality
Materials
                       with an Advanced Design
                                       so you get Extreme Performance!

 

 


With all of the brushless motor choices available on the market, it is important to understand why we are different. Anyone can wind magnet wire and assemble a motor, but only a few can design a motor specifically for the RC enthusiast. All of our motors are designed in the USA by Medusa Research’s experienced electric motor engineers, and were created with the needs of RC models in mind. Our design is the result of cutting edge computer simulation and years of real-world testing. For performance, price, and quality of workmanship, our motors are simply the best on the market today. Medusa’s 28mm motors are designed to be speed 400 replacements that not only give you the efficiency of a brushless motor but even more power. These motors have identical mounting screw locations and come in 3 different lengths. The wide selection of Kv ratings make it easy to select the motor with the perfect size and power for your model whether it is direct drive or for gear drive applications.

Compare our specifications and you will see Medusa’s 28mm motors are the best choice for your model.

*Based on adequate air flow around motor, i.e., open air stream behind propeller
**Max I can be present for 30 seconds
All Medusa Research motors are rated for 60,000 RPM operation
For the best efficiency, your ESC should be setup with 8º to 15º advance, and a switching rate of 10 to 20kHz.
The above motors have 4 poles.
