EMAX RS2205 RaceSpec Motor 

This is one of the recommended motors for the ImpulseRC RR5 Alien Kit.

These Emax “Red Bottoms” are an economical alternative to the Lumenier 2206 2350KV Motor. Chad Nowak started flying these just to test them, but ended up liking them a lot!

The manufacturer claims the unique fins machined into the bell draw up cool air from the motor base. The faster it spins, the more air it ventilates. Cooling fins significantly reduce heat soak by at least 30%. This “cool” feature allows the RS2205 to last longer.

The Red Bottom motors also use high grade N52 Magnets. This means better acceleration, stopping power, and sustained RPMs during high kv. This performance is supported by genuine Japanese NMB Bearings to provide long lasting, smooth performance.

This motor is a good match for the HQ 5x4x3 props available in our store.

Well loved motors packaged with love by Rotor Riot

The ever famous red bottoms don't disappoint and being able to buy at a stellar price via the RR guys is as good as it gets. Packaged with love and even a few stickers thrown in, you can't beat it!

Highly Recommended

These motors are awesome! I'm running these with the purple bullet 30A emax escs, and it is the most responsive out of all the quads I've flown.
