Brushless motors are getting more common in 12th scale racing. The problem with most brushless esc are that they have a large heat sink with a fan mounted on top which could be a big problem with the bodies used. most bodies have very low profile where the esc normally is placed. Now Novak have created the GTB 4-Cell Programmable Racing Brushless/Brush ESC which a 30% smaller height profile as to the normal GTB. The GTB 4-Cell Programmable Racing Brushless/Brush ESC has also 16-gauge wire, which helps lighten the ESC's weight by 25%. Other differences from the original #1710 GTB include a replaceable input harness and switch harness, both of which are "re-solderable" for retaining the ESC's low profile and for added convenience.

This versatile ESC is compatible with all Novak 540-size sensored brushless motors, and has no brushed motor limit. Like all of Novak's speed controls, the GTB 4-Cell is packed full of features. 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.
