Fettec 35a ESC

Finally! A 20x20 option that was developed to go hand in hand with KISS. Just as ultra smooth, ultra fast, but with a higher constant amp rating. But there's a couple of things that make this ESC very special. One is Fettec's new OneWire protocol and Full sine wave control. OneWire allows for ONE cable to transmit motor and telemetry data for ALL 4 motors! Talk about making it easy! And the other is it's use of Full Sine Wave control. Where other ESC's signal looks more like "stairs" to go up and down (signal goes up in "steps") full sine wave looks like a linear curve (no steps).

Works for all Ummagawd frames, and a perfect match for the Fettec FC.

Be sure to get the spike absorber for 6s use.
