Scorpion RS-3420 21.5T ETS version brushless motor

Scorpion’s RS-3420 21.5T ETS electric brushless motor builds on the proven RS-3420 series modified and stock motors for exceptional performance and drivability. It features a 12.5mm rotor with patented screw-type surface for maximum torque and low running temperatures while a built-in cooling fan further reduces internal heat built-up. The can’s heatsink design offers up to 200 percent more cooling surface compared to plain can motors while a special design allows to maximise the copper fill of the windings. The motor, that is the hand-out motor for the Formula class of the Euro Touring Series, comes with special ETS markings for easy identification and it is available now.
