Polar Drive Technology, created by Novak Electronics, has revolutionized electronic speed controls with its advanced circuitry. The results include several advantages which allow speed controls to handle more power, run longer and faster than conventional speed control designs, have an increased radio range and better throttle response.

Another key feature of Polar Drive Technology is its ability to overcome one of the biggest fundamental problems with today's speed controls: overheating at partial throttle.

At partial throttle, speed controls become less efficient and turn battery power into heat. As a result, the overall speed and run time of the vehicle is reduced. Although increasing the number of drive transistors and the quality of the transistors helps performance at full throttle, the result is a drastic reduction in performance at partial throttle.

With Polar Drive Technology, the drive transistors are driven in such a way that losses during partial throttle are reduced to a minimum without sacrificing radio range. Using this same technique on the brakes increases the recharge to the battery pack, allowing longer run times.

Novak's Tempest Pro, designed to be the best racing speed control available, was the first ESC to incorporate Polar Drive Technology. Novak's design engineers worked diligently with their team of elite drivers to perfect the speed control that world competition demands.

Polar Drive circuitry combined with six HYPERFET II drive transistors allows the Tempest to handle considerably more power. As a result, heat sinks are no longer required. Even while driving seven-cell, four-wheel drive modified cars, the Tempest is able to maintain exceptional performance while the transistors stay cool. No other speed control available can match this performance level.

After the development of the Tempest, Polar Drive Technology was incorporated into an entry level ESC with excellent results: the Explorer Sport was smaller and cost less than any previous ESC that Novak had developed. Novak was able to match the performance of more expensive five transistor speed controls with just three drive transistors as well as having better throttle response and added radio range.
