The Aerostar RVS range of brushless speed controllers is designed for fixed wing aircraft. They feature super smooth start up, linear throttle response, multiple protection features and a reverse function designed with seaplanes in mind, but also useful for other applications like Short Take Off & Landing (STOL). Always ensure your motor has stopped before going into reverse.

Although primarily designed for fixed wing aircraft they do also include a soft start and heli mode making them a good low-cost alternative ESC for your next helicopter project. If you don't need to use the reverse function, simply don't connect the second lead to your receiver and the ESC will operate as a normal one.

Installation is very straightforward as these speed controllers come "plug & play", no soldering required, they are pre-fitted with an XT60 connector at the battery end and 3.5mm gold connectors for the motor.

Programming can be done either using the transmitter and listening to the tones or you can use the dedicated programming card (see "Related Items").
