Novak Electronics has introduced their latest top-of-the-line ESC for competition electric RC racing; the GTX. This is the smallest and lightest racing speed control according to Novak. Although it only just been released, this ESC has already won some significant titles including the 2004 Reedy Race of Champions, 2004 ROAR 1/12 Carpet Nation Champion, 2003 Cleveland Indoor Champion in modified touring, ROAR 2004 Modified 4WD Off-Road National Champion, and 2004 Snowbird Touring Champion.
Thanks to some pretty sophisticated new MOSFET technology, Novak was able to design a significantly smaller, lighter, and more powerful ESC than ever before (1.11″ x 0.86″ x 0.60″; 0.64 oz). The small size was achieved without sacrificing any of Novak’s signature features such as One-Touch Set-Up, Polar Drive Circuitry, and Radio Priority Circuitry. It also has Digital Anti-Glitch Circuitry, and is the only programmable racing ESC with built-in Thermal Overload Protection and a 36 Amp Schottky Diode. So not only is the GTX extra small (it’s even smaller than Novak’s XXL receiver), it’s packed full of features, power, and built to withstand the rigors of competitive R/C racing.
Part of the GTX’s unique makeup is that it is built with six layers of gold-plated powerboards, which help increase its power-handling capabilities. Externally, the GTX also features low-resistance gold-plated PCB Direct Solder Wire Tabs. When used with the included Novak Super-Flex silicone wire, users are assured of the lowest possible voltage drop, as well as easy and convenient power wire and power capacitor replacement. The GTX uses a 6 volt/3 amp BEC, which allows faster servo response and better torque-holding capability. For a perfect fit in any vehicle, a combination input harness/power switch that comes with both a long and short length input harness is included so you can get a custom looking install without having to figure out what to do with the extra wire.
The GTX has seven throttle programs that are pre-programmed for nearly every driver, application, and track condition. For advanced users, or people who like to tune everything, Novak has incorporated a 7th program that can be customized by using the One-Touch Set-Up button (no external programming device required). Four different color LEDs help make programming even easier by providing prompts. The 7th program offers similar settings to the other six programs, but allows you to adjust drive frequency, minimum drive, brake frequency, minimum brake, dead band, and two different types of braking: standard constant force braking or drag brakes.
