manual Manual

Please Note: DelTang receivers may be in short supply. If the receiver you want is out of stock you can contact us by email to be notified when it is back in stock.

The Rx31d is a 4 channel receiver unit for use with micro servos like the BioMetal or Linear servos. To save weight it has no connectors and you can solder the servo wires directly to the pads. This also makes the unit ideally suited to extreme micro applications where weight needs to be kept to a minimum.

The main feature of this receiver is it's ability to handle "Differential Thrust Steering". To do this the receiver has two x 2Amp brushed ESCs onboard which can each power their own brushed motor. You can configure control of two brushless motors. The differential rates on each motor can also be adjusted.

This is a DSM2 compatible receiver unit which can be bound to a Spektrum DSM2 capable transmitter or any other transmitter which is DSM2 capable.
