Electronic speed monitor
Order No. 3555
$100.71 CAN
The electronic rotor speed monitor is installed in the model, and immediately alerts you if the main rotor speed exceeds a pre-set value.
The monitor makes it much easier to determine the main rotor speed from the throttle curve, and is particularly valuable when setting up a helicopter. Three magnets are mounted on the main rotor shaft, and transfer the rotational speed directly from the shaft to the sensor without physical contact.

The monitor is powered by the receiver battery, and two ultra-bright LEDs are used to indicate that the unit is ready, and that the rotor speed has exceeded the set limit.

The following values for the pre-set rotor limit speed can be selected, via dip switches: 850, 900, 1000, 1270, 1350, 1500, 1600 and 1700 rpm.
Electronic speed monitor, complete with sensor holder and three magnets.
