Always a technological leader, Novak has upgraded the GTB ESC to work with spread spectrum systems from manufacturers such as Spektrum™, Nomadio™, and Futaba™. Since spread spectrum technology uses a much higher frequency, 2.4Ghz to be precise, this has allowed Novak to finally unleash the full potential of the GTB speed control. Both new GTB models now have significantly faster MOSFET switching speeds, which provide improved performance and cooler operating temperatures. In short, the ESC gets power and increased operational efficiency at the same time!

HIGH-SPEED SWITCH
MOSFET switching speed is a key feature for the spread spectrum specific GTBs. The MOSFET switching speed is not just the frequency of the ESC, its actually how fast the ESCs MOSFETs turn on and off. With regular radios, ESCs are limited by how fast they switch on and off. If it switches too fast, the radio system will experience interference. With spread spectrum technology this is not an issue. Novak Engineers have been able to take full advantage of this great new technology and now offer a high-speed switching GTB for all spread spectrum users. While users should not expect a huge difference in feel or driving style, they will notice improved motor operation and lower ESC operating temperatures.

While Novaks two new GTB models have been equipped to work with spread spectrum technology, all of the same great Novak features have been left intact, including six throttle profiles (5 brushless, 1 brushed). These versatile ESCs are compatible with all Novak 540-size sensored brushless motors, and have no brushed motor limit. A user-friendly interface along with 4 different color status LEDs make programming the GTB extremely easy. The brushless mode has 4 adjustable parameters, including Minimum Brake, Drag Brake, Deadband, and Minimum Drive. The brushed mode is fully programmable with all of the adjustments of the brushless mode, plus adjustable Drive Frequency. The GTB also uses exclusive lightweight MOSFET technology, which have the lowest RDS On value, and which allows the speed control to have the highest power density.


In addition, the GTB Spread Spectrum Brushless/Brush ESC includes Built-in Li-Po Cut-Off Circuitry, which monitors the vehicles Lithium Polymer battery packs voltage, and prevents the batteries from going below the critical safety voltage level (6.25 volts).
