Product overview
The Maytech MT20A-BEC-HS2 Harrier Suprem V2 32bit is a brushless electronic speed controller for integration into RC fixed-wing aircraft and helicopters. Its electronic architecture combines a 32bit microprocessor with a separate voltage regulator IC for the microcontroller, supporting interference resistance. The controller runs Harrier Suprem V2 32bit firmware and provides a 5.5V/4A BEC. For this model, the electrical ratings are 20A continuous current and 25A burst current, with an input specified as 2-4 cells.
Integration and setup center on motor wiring and programmable settings. Parameters can be adjusted through Trx or an optional Maytech programming card; the card is an accessory rather than standard included equipment. Motor direction can be changed by swapping two of the three ESC wires or through the card. Low-voltage, blocked-rotation and signal-loss protections are provided. At battery connection, the startup safeguard prevents the motor from starting regardless of throttle-stick position. The product is an ESC component for installation in a host aircraft.
