This is the GTB competition brushed and brushless motor electronic speed control and Velociti 6.5R motor package from Novak! This package includes both the GTB brushed and brushless competition speed control as well as the Velociti 6.5R brushless racing motor.
About the GTB ESC
The speed control used for both of the new systems, the GTB Racing Programmable Brushless/Brush ESC, is packed full of features. This versatile ESC can be used with either brushless or brushed motors, has no brushed motor limit, and is compatible with all Novak 540-size sensored brushless motors: Velociti 5.5 Racing (5 1/2-turn), Velociti 6.5 Racing (6 1/2-turn), SS5800 (8 1/2-turn), and SS4300 (10 1/2-turn).
The GTB is also programmable with a user-friendly interface, including 4 different color status LEDs that make programming extremely easy. The brushless mode has 4 adjustable parameters, including Minimum Brake, Drag Brake, Deadband, and Minimum Drive. The brushed mode is fully programmable with all of the adjustments of the brushless mode, plus adjustable Drive Frequency.
The GTB uses exclusive lightweight MOSFET technology. These MOSFETs have the lowest ‘RDS On’ value, which allows the speed control to have the highest power density. The GTB uses more than twice the number of MOSFETs as the GTX, Novak’s competition ESC, making it the ultimate speed control for brushed and brushless motor performance
.
Like the GTX, the GTB includes all of the extra performance-enhancing components required for world-class racing, including a factory-installed heat-sink and cooling fan. Other convenient features include One-Touch Set-Up, direct-solder wiring tabs, and a replaceable input and switch harness. It’s also equipped with Thermal Overload Protection and a water-resistant case.
In addition, the GTB Brushless/Brush ESC includes Built-in Li-Po Cut-Off Circuitry, which monitors the vehicle’s Lithium Polymer battery pack’s voltage, and prevents the batteries from going below the critical safety voltage level (6.25 volts).
About the Velociti Brushless Racing Motor
With over 5 years experience developing and manufacturing sensored brushless motors, Novak introduces the Velociti Racing Brushless Motors. Novak’s Velociti-series brushless motors are available in both 5 1/2-turns (#3405) and 6 1/2-turns (#3406), and are compatible with the Novak GTB Programmable Racing Brushless/Brush ESC.
The Velociti brushless motors feature a higher-strength magnet for top racing performance, and an oversized front bearing for increased load handling and bearing life. Like the Novak SS-series motors, the Velociti motors are specifically designed for R/C vehicles, are sensor-based for excellent starting torque and low-speed driveability, have low cogging, provide longer run-times than brushed motors, and meet all ROAR specifications. Additional features include direct-solder wiring tabs, locked rotor protection, thermal overload protection, and a virtually maintenance-free design.
