DelTang Rx66 DSM2/DSMX Receiver for Land-Based Vehicles


Rx66 Top
Rx66 DSM2/DSMX 18V Receiver with 4A Bi-Directional ESC

Rx66 is a 2.4GHz DSM2/DSMX receiver which includes one integrated 4A reversable controller for brushed motors (ESC). The motor stall current must be less than or equal to the ESC current rating; this can be increased to 6A using a heatsink. The voltage range is 3-18v for 1-4S LiPo, 1-5 LiFe, 3-12 NiCd/NiMH or 1 PP3.

Size:46 x 26 x 4 mm
Weight:2.2 gm
Voltage Range:3V - 18V
Max Current:4A (6A with heatsink)
wiring adds 0.5gm ~ 1gm to the bare board weight
Rx6x Receiver Features

Rx66 is available as board-only for you to add wiring or with a range of pre-wired leads / connectors. Deltang have advised that a capacitor of approx 200uF should be wired across the battery pads when the receiver is used with a voltage of 12V and above. A suitable capacitor will be supplied loose when the 'no power leads' option is selected and will be attached with any other leads/connectors option. See the More Images tab for a photo of the capacitor in place. If the options below do not exactly meet your needs, please contact us to discuss your requirements.

An enormous range of programming features are provide to enable you to customise the operation of Rx66 to suit your model. See Rx66 v611 Programming for full details. Access to programming is either via a stick type transmitter or using the PROG3 programmer. A selection of program setups are provided as variants (-1, -2, etc.) - view the Variants tab for details.

The default receiver setting is for the Low Voltage Cutoff (LVC) threshold to be determined from the voltage seen on initialisation - basically, the receiver firmware makes a 'guess' at the battery type. The algorithm used for this calculation means that a 9V Alkaline or NIMH battery can often be interpreted as an almost discharged 3S LiPo. The solution is to either disable LVC, or set it to the correct value for your battery; this is done by programming the receiver.

Instructions for programming receivers using your DT transmitter are at the bottom of the information leaflet that came with the transmitter.

The receiver programming steps for LVC are:

disable LVC: 7 2 1
set LVC: 7 2 3 units tenths

e.g. to set the LVC to 6.5V, the programming steps are: 7 2 3 6 5

The receiver is normally supplied as a bare board, with wiring options as specified in the menus below. If you want the receiver protected against accidental contact with metal parts, please select the 'heatshrink' option.

The heatsink is attached to the Rx66 with a non-metalic screw through the hole in the center of the group of ESC devices. If using the heatshrink cover, this must be fitted and a rectangular hole cut into it above the ESC devices before the heatsink is attached - see More Images.
