DT / DelTang DSM2 Micro Actuator Receivers

UK designed and manufactured DSM2/DSMX ultra micro 2.4GHz receivers with outputs suitable for driving magnetic actuators (and some also with servo outputs). All of these receivers are fully compatible with Spektrum, E-flite, Parkzone and other DSM2/DSMX 2.4GHz transmitters and transmit modules. These receivers are not copies of Spektrum products.

All of the receivers have twin built-in 2A brushed ESC, which can be used for thrust steering. The throttle signal is available so you can connect an external ESC. If you do use an external ESC, simply ignore the brushed ESC output(s).

These receivers are designed for aero models. If you are looking for receivers with fwd/rev ESC for vehicles, boats, trains then take a look at the 'v5' and Rx6x receivers.

DSMX Support:
The Rx41d and Rx43d are available with beta support for DSMX. This is v3.5 firmware and, although it has been demonstrated to work with several DSMX transmitters, is is considered 'BETA' and is not proven or guaranteed. If the v3.5 software does not bind or work correctly with your DSMX transmitter, the receiver can be returned for the current stable v3.4 software to be installed; this only works with DSM2. Customers will normally be expected to pay postage both ways.

Choose v3.4 for Rx41d and Rx43d if your transmitter supports DSM2.

All actuator receivers have outputs via solder pads at 1.27mm spacing allowing the use of standard 1.27mm (0.05") sockets for attachment of actuators and/or motor(s).

Rx41d and Rx43d use the A3901 H-bridge driver chip and are capable of supplying 400mA per channel.


Rx41d DSM2/DSMX Ultra Micro Actuator Receiver with Twin 2A ESC

Rx41d is a DSM2/DSMX compatible 4 channel micro receiver with one actuator output, 3 servo outputs and twin built-in 2A brushed ESC. The actuator channel may be connected to aileron, elevator or rudder - it can also be used to drive a motor with bidirectional control. The rudder or aileron channels may be mixed into throttle for differential thrust steering. Twin throttle signals are also available for driving external ESC.

Size:10.1 x 10.8 x 2 mm
Weight:0.28 gm

Please see note above about DSMX support


Rx43d DSM2/DSMX Micro Actuator Receiver with Twin 2A ESC

Rx43d is a DSM2/DSMX compatible 4 channel micro receiver with three actuator outputs, 3 servo outputs and twin built-in 2A brushed ESC. The rudder or aileron channels may be mixed into throttle for differential thrust steering. Twin throttle signals are also available for driving external ESC.

Size:11.8 x 12.9 x 2 mm
Weight:0.35 gm

View the Rx43d user instructions (v3.44).

Rx43d is available in 2 versions: v3.4 that has DSM2 only and v3.5 with DSMX support. Problems with DSMX on the Rx43d have been reported so if your transmitter supports DSM2, use the v3.4.

Actuator Receivers with Bahoma

The Rx5x receivers all have 5mm space Bahoma magnets for use with LiPo cells using the Didel/Plantraco magnetic connector system. The advantage of using magnets is that the battery almost always gets ejected with a less than tidy landing (aka 'crash'), thus protecting the motor. Any of the Plantraco LiPo 5mm spaced cells may be used or you can use the MAG1 adapter board to make your own cells.

The receivers are available with and without motor/actuator sockets. The obvious weight advantage of using no sockets has to be balanced against the need for precision soldering of the actuator wires. The optional connectors are 1.27mm (0.05") pin spacing.


Rx53 DSM2 Ultra Micro Actuator Receiver with 2A ESC

Rx53 is a DSM2 compatible 4 channel micro receiver with 3 actuator outputs and built-in 2A brushed ESC. A throttle signal is also available on the circuit board for driving an external ESC.
