The Team Orion Vortex Race Spec BL ESC is a brushless speed controller for racers. It features the latest brushless technology and is ready for the hottest motors on the market. VFS - Variable Frequency System The unique variable Frequency System is responsible for the super smooth response of the controller. It optimizes the driving frequency in relation to the throttle position. Like this the motor is always at best efficiency and the driver gets a smooth but precise control at any time. Ultra Low Profile Design To ensure a very low CG, the electronic components of the Vortex Race Spec controller are designed as flat as possible and are positioned as low as possible. Car designers optimize the CG of their chassis - with the Race Spec controller we follow this strategy.
