The HiCopter line of speed controllers is designed for controlling and regulating brushless motors that are typically used for multi-rotor flying platforms. Each speed controller is pre-programmed from the factory with settings optimized for use with multi-rotor stabilization systems. HiCopter controllers accept a control signal with a frequency of up to 500Hz. This allows accurately respond to any RPM changes required by the control/stabilization unit of the multi-rotor.
The throttle signal is optically (Opto) separated from the flight battery in all HiCopter speed controllers. HiCopter speed controllers do not require or allow any programming changes. The propeller brakes are already turned off, the cut-off voltage is pre-set to the lowest possible level (depending on type) and the motor timing is set automatically by the speed controller. If you need to change the direction of rotation, simply swap any of the two of the power leads.
Always install the HiCopter speed controllers according the specific instructions of your multi-rotor. HiCopter controllers accept a control signal with a frequency of up to 500Hz.
