Item No NVK-3003 Novak's High-Velociti Motors With over 5 years experience developing and manufacturing sensored brushless motors, Novak is pleased to present the Velociti Racing-Series Brushless Motors. Novak¡¦s Velociti motors are available in 7.5-turns (#3407), 6.5-turns (#3406), 5.5-turns (#3405), 4.5-turns (#3404), and 3.5-turns(#3403). All are compatible with the Novak GTB Programmable Racing Brushless/Brush ESC (#1710), to which the Velociti motor comes factory-wired when purchased as a system. The GTB/Velociti brushless systems include all of the extra performance-enhancing components required for world-class racing, making them ready-to-race straight out of the box (nothing extra to buy or install). Because the Velociti motor was specifically developed for the GTB, and the entire system is factory-tested, racers can be assured that the GTB/Velociti system will provide optimum performance. To find out which motor or motor system is best suited for you, see below: GTB/Velociti 3.5R This is ideal for customers wanting Novak's fastest brushless motor and fortop-level competition touring car applications.(#3000) Velociti 4.5R This is the fastest Velociti motor and is ideal for competition touring cars(#3404/#3001) Velociti 5.5R Ideal for competition touring cars and high-traction off-road applications (#3405/#3002) Velociti 6.5R Ideal for Off-Road and low-traction applications and faster than the Velociti 7.5 (#3406/#3003) Velociti 7.5R Ideal for Off-Road and low-traction applications (#3407/#3007) Each Velociti brushless motor features a high-strength magnet for top racing performance, and an oversized front bearing for increased load handling and bearing life. The Velociti motors are specifically designed for R/C vehicles, include solder tabs, thermal overload protection,provide longer run-times than brushed motors, and are virtually maintenance-free. Of its many features, its sensor-based design allows for most of the Velociti's important benefits, including the following: No Cogging--Thanks to constantly knowing the rotor position, drivers experienceinstantaneous throttle response & smooth transitions from neutral to drive. The rotor position knowledge is attained due to the ESC & motor being continuously synchronized via the motor harness. Smooth & Controlled Low Speed Driveability--Always knowing the rotor angle is key to smooth acceleration without delivering abrupt and uncontrolled bursts of power. Strong/Consistent Brakes & Starting Torque--Rotor position knowledge results in consistent starts & stops, without hesitation or inconsistent lag times before acceleration or braking--this translates to consistant lap times. Thermal Protection--Position & temperature sensors inside motor provide unparalleled thermal protection, letting you to run pack after pack without worrying about overheating the motor, ESC, or magnets. All Novak brushless motors are designed and manufactured in the U.S.A. Each motor is factory hand-wound and is put through rigorous testing, including a final dyno test to ensure that each Velociti motor meets Novak¡¦s rigid specifications. The Velociti motors are available for individual purchase (#3403, #3404, #3405, #3406, and #3407), or sold as a system (#3000, #3001, #3002, #3003, & #3007) with the GTB ESC. When purchased as a system, it includes the GTB Programmable Racing Brushless/Brush ESC, and a Velociti Racing Brushless Motor. A GTB System provides a great value to the customer as everything is installed and ready-to-go, with the bonus of additional savings over purchasing the motor and speed control individually. Because the Velociti motor was specifically developed for the GTB, and the entire system is factory-tested, racers can be assured that the GTB System will provide optimum performance. [Please note, the Velociti-series brushless motors are not for use with Novak's Super Sport ESC. The Super Sport and Super Sport Plus ESCs are rated for use down to 8.5 turns brushless.
