Scorpion RS-3420 4.5T Brushless Motor for 1/10 and 1/12 RC Racing Cars

The Scorpion Power Systems RS-3420 is a brushless DC car motor designed to meet IFMAR standards for use in 1/10 and 1/12 scale electric RC racing cars. It uses high-temperature components.

Key features

• Patented screw-type rotor surface increases flux density and cooling; a built-in rotor fan increases airflow and reduces internal temperatures
• No plastic inserts in the motor windings, allowing maximum copper fill
• Rotor magnets protected by a metal sleeve; the largest glued surface for rotor, shaft and magnets of any motor in its class
• Built-in temperature sensors allow on-track monitoring when used with a Scorpion ESC
• 200% more cooling surface than comparable motors for heat dissipation
• High-grade silicon steel stator for maximum flux density and high-purity copper wire for lower internal resistance
• High-temperature magnets; motor parts CNC-machined from 7075 aerospace-grade aluminium alloy
