Extreme 1/10th Scale Fun at an Affordable PriceNovak’s Hammer ESC offers 100% pure, sensor-based control and precision driving to enthusiasts looking for an affordable, incredibly smooth-driving power upgrade for their 2WD 10th scale off-road short-course truck, 4WD or 2WD off-road buggy, and even power-hungry on-road cars. The ESC is 2S and 3S LiPo capable, is pre-wired from the factory and includes gold-plated bullet connectors for easy installation!Novak´s Hammer controller is based on Novak’s proven 1/10th scale ESC design. Drivers new to the Novak platform will experience a much more connected feel to their vehicle with strong braking control. The sensor-based design is key, and it is no surprise this is the standard in the racing world. Compared to a sensorless controller, it has controlled responses under load, with no cogging or hesitation. The Hammer is factory-defaulted to LiPo mode with reverse turned on. Drivers can customize the Hammer firmware to suit their driving style, including Throttle Curve, Brake Power and many other parameters. No clumsy or complicated programming device needed – the Hammer is fully programmable with a press of a button!Fun in the ElementsBig power means lots of fun, and often fun in all conditions. Designed with a silicone-gasketed sealed case, the Hammer is protected from just about anything you run it through. Its extreme resistance to water, dirt, and other debris gives users confidence while running through the occasional jaunt through the water.Added ProtectionNovak has been designing and building sensor-based controllers since 2002, longer than any other company in the industry. Circuitry protection has always been at core of the design. The Hammer firmware includes thermal overload protection, low-voltage protection, and motor lock-up protection for added reliability. Additionally, on-board diagnostics are standard in the firmware including a motor sensor checking test, error sensing, and on-board temperature diagnostics.Specs:Motor Type Sensored Brushless (2 and 4-pole)Fwd/Brk/Rev F / B / RInput Cells (LiPo/Ni-MH) 2S and 3S LiPo/LiFe or 4-9 NiMHDimensions (in/mm) 1.4" x 2.0" (35 x 51 mm)Height (in/mm) 0.9" (24 mm)Weight (oz/g) 1.4 oz.
