Replacement GT Speed Controllers for the E-Savage are now available through HPI Racing. The GT ESC bolts right into the E-Savage and is designed for twin batteries (14.4 volts!) and twin motors. It comes complete with all of the standard plugs and switches for easy installation. A purple anodized heat sink keeps the electronics cool, and a built-in Fail Safe protects the ESC from damage. Set-up is easy with the FASF (Fully Automatic Setup Function), just power it up and start driving! Fully proportional throttle and brake assure that you have precise control at all time, and the built-in reverse feature lets you back out of situations where other trucks would get stuck!
COOLING FAN SET FOR GT SPEED CONTROLLER
E-Savage owners can now add extra cooling for their ESC with the Cooling Fan Set for the GT Speed Controller. This bolt on fan set is easy to install and provides active cooling for the heat sink to keep temperatures at a safe level even in hot climates or during heavy duty driving. The fan plugs right into the front panel of the speed controller and bolts to the heat sink. An included chrome grill prevents objects from being damaged by the fan. This HPI factory option part keeps your GT ESC cool when the going gets tough!
