GWS electronic speed controllers
A range of high frequency (2.8 kHz) speed controllers suitable for the new generation of micro slow flyers and also standard slow flyers through to high performance 400-600 powered R/C gliders. The ICS series are notable for their micro size (ICS-50 PCB weighs a mere 1 gram!). ICS series are designed as aircraft speed controllers with forward function only and feature battery elimination circuitry (BEC) plus a preprogrammed auto-cut function which cuts power to the flight motor at the end of the battery run.
Their new Li-poly speed controllers autodetect your 2 or 3 cell Li-poly pack so theres no need to use a different speed contoller with a different pack.
