Description:
IMPORTANT NOTE: Fettec have advised that the active current limiting feature will not protect against burst current. We recommend that motor/propeller combinations used with this ESC draw no more than 35A continuous, as blown MOSFETs will likely not be covered under warranty over this current limit.
This is the second ESC released by FETtec. This ESC supports both KISS and Betaflight and runs at Dshot 2400. It supports 3-6S input and if running on 6S, it also has direct mounting options to add capacitors to ensure your circuits are running clean. Bottom line this is one awesome ESC to get the most out of your motors.
Works great with the FeTtec Kiss F7 FC

What is Full Sine Wave Control?
Most ESC control the FETs by simply turning them on and off which works, this means the power change as the current moves form one phase of the motor to the next is very abrupt (image below left graph). This effect is what causes the whining on brushless motors. A sine wave controller on the other-hand, still uses FETs to control the current to various phases in the motor, but the power change is applied smoothly (image below right graph).
