Novak has reinvented the HV Brushless System Series since it was released in 2006. The series now includes four motor winds, new programming, a MOSFET upgrade and a design makeover. The HV Pro Brushless System is made up of the new generation of rugged HV Brushless Motors with 5mm Shafts and specially designed HV Pro High-Voltage Brushless ESC that work seamlessly together to provide the ideal system for high-voltage applications. The new HV Systems were specifically developed by Novak for R/C cars, and are ideal for monster trucks - such as the Traxxas® E-Maxx™, Traxxas® E-Revo™, HPI® E-Savage™ and Kyosho® Twin Force™-- converted electric 1/8-scale vehicles and vehicles with massive power needs.

HV PRO SYSTEM WINDS
Novak's HV Pro Brushless Systems with 5mm Shafts are available in four motor winds:

• HV Pro Brushless System 4.5T with 5mm Rotor (Kv=5,000; Watts=890) is best used for short, high-speed runs (#3024).
• HV Pro Brushless System 5.5T with 5mm Rotor (Kv=3,700; Watts=800) has superb control, and excels in racing and bashing applications (#3025).
• HV Pro Brushless System 6.5T with 5mm Rotor (Kv=3,400; Watts=730) is the best all-around-motor with a great balance between power and run time. It also shines in racing and bashing applications (#3026).
• HV Pro Brushless System 7.5T with 5mm Rotor (Kv=3,000; Watts=620) has incredibly smooth power delivery, making it the easiest to drive, and is recommended for users looking for the longest possible run times (#3027).

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 braking, the HV Series of motors (#3524-3527) 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/BRUSH 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. This high-power, reversible brushless speed control is also easy to install and operate. The HV Pro uses the same screw pattern as the Traxxas® E-Maxx™, Traxxas® E-Revo™, HPI® E-Savage™ and Kyosho® Twin Force™, making it convenient to install, and it includes a Power-Boost ESC Cooling fan kit and factory-installed motor heat sink for superior cooling.In addition, the HV Pro High-Voltage Brushless ESC includes many of the same great features found in high-quality Novak ESCs, such as One-Touch Set-Up, Thermal Overload Protection, a powerful BEC, Polar Drive and Digital Anti-Glitch circuitry and Smart Braking II.

Novak has also done away with the external Li-Po module with the inclusion of the built-in, auto-detect Smart-Stop Li-Po Cut-Off Circuitry*. When active, the Cut-Off Circuitry automatically switches to the proper Li-Po cut-off voltage for the connected battery packs, preventing the batteries from going below the critical safety voltage level.

The HV Pro ESC’s makeover doesn’t end there. In addition, the ESC has been updated with black heat sinks for better heat transfer and a new case label. You won’t mistake this high-voltage system with any other!

HV PRO PROGRAMMABILITY
In addition to the upgrade to full programmability, Novak’s HV Pro High-Voltage Brushless ESC (#3221) has three throttle profiles – two with reverse and one with forward/brake. Each throttle profile has on-board programming for extreme versatility and unmatched customization for Minimum Brake, Drag Brake, Dead Band, Minimum Drive, Throttle Curve, Brake Frequency, Brake Disable, Motor Rotation and Li-Po Cut-Off. These programming features make operating an R/C car as easy as One-Touch set-up. Novak’s new Throttle Curve adjustment allows drivers to tailor the throttle response, creating either a quick burst of power with the Linear Curve setting, or a smoother, controlled low-end power delivery with the Expo Curve setting.

5mm Mod 1 Hardened Steel Pinion Gears 5mm 32-Pitch Steel Pinion Gears

GEARS
To mesh with the HV Brushless Motor’s rugged 5mm output shaft, Novak also offers two series of precision steel pinion gears. Novak’s 5mm Mod 1 Hardened Steel Pinion Gears (#5100-5110) are recommended for Novak’s 1/8-scale Conversion Kits (#5010-5019), and Novak’s 5mm 32-Pitch Steel Pinion Gears (#5152-5157) are recommended for powering monster trucks that use a 32-pitch plastic spur gear.

Like all Novak brushless systems, the brushless speed control and brushless motor are factory wired and tested together, so they are ready to “plug and play” straight out of the box.
