Graupner speed controllers have been famous for their quality and versatility in a broad range of model applications. This programmable high voltage ESC (5S 12S) enables setup modes for airplanes, helicopters, boats and cars where each mode provides the optimum performance and settings for your model.
To ensure trouble free and safe operations the Graupner ESC has Cool FET technology (Active Freewheeling) as well as multi-level protection circuitries to protect the ESC from damage under extreme operating conditions.
Programming can be done with the radio stick, optional programming box or over the air with a Graupner HoTT radio. The ESC provides continuous real-time telemetry information of Min/Max current, capacity, voltage, RPM and temperatures and can also be programmed to provide alarms when certain system values have exceeded to warn the user beforehand.
This OPTO ESC version does not have an internal BEC and therefore requires a separate power source to power your receiver.
