Introducing the newly improved S version of the original Red Bottom Emax high performance brushless motors for multirotor FPV racing. Redesigned and engineered to perform better than most in it’s class, every motor is precision crafted within tight tolerances. Paired with performance driven props this motor boasts independently tested thrust thrust numbers in excess of 1300g.
The unique fins machined into the bell draw up cool air from the motor base and through the coils as the motor spools up. The faster it spins, the more air it ventilates. Cooling fins significantly reduce heat soak by at least 30%. This “cool” feature allows the RS2205S to not only have a longer lasting motor, but also harness the power of N52 magnets.
