Novak has reinvented the HV Pro High-Voltage Brushless ESCs yet again since it was released in 2006. The series now includes new programming, built-in Li-Po Cut-Off Circuitry and a design makeover. The updated HV Pro ESCs were specifically developed by Novak for R/C cars, and are ideal to power monster trucks — such as the Traxxas® E-Maxx™ and E-Revo™ — converted electric 1/8-scale vehicles and vehicles with massive power needs.

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™ and E-Revo™, 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 circuitries 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 PROGRAMMABILITY
In addition to the upgrade to full programmability, Novak’s HV Pro High-Voltage Brushless ESC has been updated to 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.

For HV Pro High-Voltage Brushless ESC can be factory wired to one of four HV High-Voltage Brushless Motors with 5mm Shafts (#3524-3527) to create the HV Pro Brushless System with 5mm Rotor (#3024-3027).
