First seen on Red RC during our coverage from Thailand, Team Orion have officially announced the Vortex Race Spec BL ESC, a brushless speed controller designed for racers. It features a variable frequency system, a unique system that is responsible for the super smooth response of the controller through optimizing the driving frequency in relation to the throttle position. This ESC also sports an ultra low profile design, which has been achieved by designing the electronic components to be as flat as possible and by positioning them as low as possible. The Race Spec Controller comes with 5 pre-set setups which have been optimized by their international racing team and these settings work the best for the most popular categories. For pro’s who want to adapt the setups, it is possible to do so using a special USB cable and software. The brushless sensor technology is ready for motors with at least 4.5 turns (without fan) and 2.5 turn motors with fan and you can buy the controller with and without cooling set.
