Speed Passion have released 4 speedo and motor combos specifically tailored for short course racing. The first combo is the Cirtix Short Course Master combo that utilizes their 3600kv custom Short Course brushless motor giving a perfect balance of improved speed over the stock power system, but not so over the top that handling is compromised by excessive power. The setup and options of the Cirtix Short Course Master ESC is as easy as it gets with one button setup and pocket programming card. This combo is also available with a more powerful 2100kv 17.5T Ultra Sportsman motor. Next up for 4×4 short course trucks is the Cirtix RR ESC and 4000kv motor combo. The Cirtix RR features easy settings changes, a robust alloy heat sink & integrated case and the smooth power of a racing sensored ESC. Finally for 1/8th 4×4 SC trucks is the Cirtix R8 Short Course ESC combo that includes the Silver Arrow 5.5T motor. The ESC features sensored or sensorless operation, 4 cell LiPo capability and an awesome new fit-anywhere footprint. From the super tough all alloy heatsink case to the smoothest most responsive throttle feel you’ll ever experience, it is made to put the hammer down in the rough 8th scale environment.
