NOVAK’S NEW SPORT ESC IS ANYTHING BUT SPORT, IT’S EXTREME​


Irvine, CA – March 27, 2007 – Novak’s new XBR Sport Brushless/Brush Speed Control is anything but sport. It’s an extreme sport model ESC that allows drivers the ability to put in seemingly endless practice time with the minimal maintenance of brushless, yet it also gives the ultimate performance on race day with a brushed motor.

While the XBR has the word “Sport” in its title, its many high-performance features will dispel any notion that this ESC is for entry-level users only. The XBR is equipped with many of the same, if not better, features of Novak’s top-of-the-line GTX Racing ESC. The XBR even has a lower on-resistance!

NEW NOVAK features INTRODUCED IN SPORT ESC

The XBR has the distinction of being the first Novak ESC to include two great features new to Novak products. Because the XBR is compatible with both brushless and brushed motors, the first feature is especially ideal. The Auto-Detect Brush Mode detects when a brushed motor is connected, and automatically switches the ESC to its Brush Profile to ensure the system will run at the optimal settings. The next feature to make its debut in a Novak ESC is the Built-in Motor Rotation Selector. This feature enables the user to easily select the direction of the motor rotation. This feature is ideal for vehicles with drivetrains that require the motor to rotate clockwise (rather than its normal counter-clockwise rotation).

Protection features

The XBR provides the most protection you can get at a sport-level price.

Ø Water-resistant case to keep out debris and moisture.

Ø Built-in Li-Po Cut-Off Circuitry, whichmonitors the vehicle’s Lithium Polymer battery pack’s voltage, and prevents the batteries from going below the critical safety voltage level.

Ø Locked Rotor Detection Circuitry prevents ESC and motor damage (when used with brushless motor)

Ø Thermal Overload Protection prevents damage to ESC and when temperatures exceed a safe level

Ø Built-in power output for an optional accessory fan, which is ideal to utilize especially for the high demands of brushed motor racing.

FOUR PROGRAMMABLE THROTTLE PROFILES

Another XBR feature that breaks the sport mold is its multiple throttle profiles with full programmability, all without the need for a computer laptop. Within each of its four throttle profiles, the XBR has 4 Adjustable Parameters: Minimum Brake, Drag Brake, Dead Band, and Minimum Drive; the brush mode also includes Drive and Brake Frequency adjustability for further throttle customization.


The XBR is equipped with four user-selectable throttle profiles, two of which have reverse:

Ø Standard Brushless Mode (with reverse)

Ø Sport Brushless Mode (no reverse)

Ø Marine Brushless Mode (25% reverse)

Ø Racing Brush Mode (GTX performance with no reverse)

MOTOR COMPATIBILITY & BRUSHLESS SYSTEMS

The XBR Sport ESC is compatible with both sensored brushless and brush motors, including Novak’s new line of sport brushless motors, the EX-Series (see separate press release), Novak’sPro Series (SS8.5 Pro, SS10.5 Pro and SS13.5 Pro), and even Novak’s Crawler 18.5T motor. The XBR Sport will be available for purchase separately, or as a combo item with one of Novak’s new EX8.5, EX10.5, or EX13.5 brushless motors. Like all Novak brushless systems, the brushless speed controls and brushless motors are factory-wired and tested together. The XBR Sport/ EX Brushless Systems are “plug and play” straight out of the box.

I got to look one over last week. It’s actual a very nice set-up and makes it very simple for Sport users to switch from brushed to brushless motors. It’s about the size of a GTB but with a little more rectangular shape.

With a street price in the $135 range it should be a good seller. The ESC combo with the EX13.5 motor for $189 should make for a good entry level or spec brushless class.

with the newer technology will this one outperform the GTB ?

By looking at the retail prices above, does that mean the esc/4300 motor combo is going to be about $189 street price as well ?
