Item No NVK-1735 THE PROFESSIONAL HAVOC Novak's Havoc Pro Brushless ESC (#1735) tops the list in the Havoc line because of its unmatched speed, economical price and advanced compatibility: The Havoc Pro is compatible with the entire Novak 540-sized brushless motor line and any ROAR-approved 540-sized sensored motor, all the way down to 3.5-turns. A LOT OF PROGRAMMING IN A SMALL PACKAGE Novak has packed the Havoc Pro Brushless ESC full of programmability into one easy-to-adjust profile. The Havoc Pro includes a customizable Throttle Curve, which smoothes out throttle operation. In addition, the Havoc Pro's Brake Frequency adjustment contains seven degrees of adjustability from a smooth and controllable brake to a more abrupt and grabbier feel. The dozens of adjustments allow drivers to fine-tune their vehicle's throttle braking for better control and advanced handling. Havoc Pro/Ballistic Brushless System installed in a Team AssociatedR SC10™ Short Course Truck. But the customization doesn't end with braking. Novak also has built-in Battery Type Selection that auto detects among Li-Po, Li-Fe and Ni-MH batteries and prevents them from going below the critical safety voltage level, and a Motor Rotation feature that allows the user to easily select the direction of the motor.
