The HT-6A is similar in operation to the DS-600 but obviously has the second joystick and the parameters are set using the buttons either side of the display. I find this one a little more precise due to the longer joysticks. It uses disposable batteries but also has the capability of running from a lipo pack (purchased separately).

The HT-8A has multiple menus on the colour display with the capability of fine tuning all the radio parameters. It also has mixing ,so can handle tank style driving just like the other two radios. The degree of configuration is amazing for such a low cost radio (currently around £25). I have yet to try it in combat but first impressions after setting up are very positive. I think it will definitely improve the standard of my driving!

The Hot RC 6 and 8 channel receivers are the same size and can be a bit bulky for antweight robots. I have used these, but had to remove the circuit board from the case and solder the servo wires direct to the PCB . A better choice is the F04B 4 channel micro receiver. This does not have the monitoring function for the model battery but is only about a third of the size of the other two.  The plugs used are sub-miniature with a pin spacing of 1.5mm (not 1.25mm as stated on some adverts). The wiring is also a bit unusual and my one would not work when first purchased due to incorrect wiring. On this radio the signal pin is on the right as shown below. For my antweight, I replace the servo and ESC wires with the correct ones for the receiver. If you prefer to use standard connectors there is a slightly larger 4 channel receiver (F-04B) that has standard servo connectors. The HotRC transmitter range is compatible with all their receivers.
