This is the Novak HV Pro 6.5-Turn Brushless Motor and ESC System.  This motor has a massive 5mm shaft for the most possible strength.  Novak had bright ideas for its HV Brushless Motor Series when the motors were released in 2006, and the series has continued to grow.  This new HV Pro design works great in vehicles like the Traxxas E-Maxx, E-Revo, Kyosho Twin Force, and Tamiya TXT trucks, as well as the 1/8 scale buggy electric conversions.  The included 6.5-turn motor in this system is the best all-around-motor with a great balance between power and run time. It also shines in racing and bashing applications.  By upgrading to this system you should notice a significant increase in performance, while also improving the run time.  These also require virtually no maintenance since there are no brushes, springs, or commutator to wear out!  This system includes one HV6.5 Brushless motor, a high-voltage Electronic Speed Control, dust cover, cooling fan, mounting hardware, and instructions.

Perfect brushless setup for Traxxas E-Maxx, E-Revo, Kyosho Twin Force, Tamiya TXT, and 1/8 scale buggies!

HV Brushless Motors with 5mm Shafts
In addition to its already impressive features, including awesome starting torque, low-speed driveability, and no cogging for smooth acceleration and smooth coasting, the HV Series has been fitted with a rugged 5mm output shaft for maximum resilience and race life. The HV Series is ideal for monster trucks, converted electric 1/8-scale vehicles and vehicles requiring massive power output. Additionally, the motors are sensor-based, so they always know the position of the rotor, which provides excellent starting torque and continuous synchronization for smooth, controlled low-speed driveability and consistent brakes. Simply stated, it means no uncontrolled bursts of power or delays! HV-Series of motors also features a shielded sensor cable with sheathed sensor wires and a completely rebuildable design.

HV Pro Brushless/Brushed ESC
Completing the HV Pro Brushless System is the fully programmable HV Pro ESC, which can accommodate 6-14 Ni-Cd/Ni-MH cells (7.2-16.8 volts) or 2S-4S Li-Po and can be wired for dual or single battery packs. It is also equipped with five throttle profiles -- three forward/brake and two with reverse -- and the same programmability as the GTB Brushless/Brush ESC. This high-power, reversible brushless speed control uses the same screw pattern as the Traxxas® E-Maxx™, making it convenient to install. The HV Pro ESC comes factory-wired to a HV Brushless Motor with 5mm Shaft. It also includes many of Novak's useful features such as One-Touch programming and One-Touch Set-Up. Novak’s Smart-Stop 4-Cell Li-Po Cut-Off Module is also included for monitoring Li-Po battery pack voltage, preventing the batteries from going below the critical safety voltage level.

HV Pro Programmability
The HV Pro ESC features 5 profiles for maximum versatility. Four of its five throttle profiles can be fine-tuned for customization and the adjustable parameters are Minimum Brake, Drag Brake, Dead Band and Minimum Drive.
