Rx31-d compared to Rx43d

[Roboteernat]

Hi all.

I have made a purchase of an Rx31-d receiver for my ant, however i have been posted the slightly more expensive Rx43-d

Rx31 - http://www.deltang.co.uk/rx31d.htm
Rx43-d - http://www.deltang.co.uk/rx43d.htm

It looks like the same except the 43 is designed to have the actuator outputs, but reading the descriptions and the instructions, it also does servo outputs - which is what i want for my custom controller/esc/switch.

Is it worth using the Rx43-d instead of asking for the actual RX31-d?

Please, any thoughts?

Also, im going to do a blog post about it, and also mod a 'Blade' DSM2 controller to have a switch instead of one of its pot arms so i can use it to 'switch on/off' an output should i want to do that in the antweight ESC/RX combo.

Thanks

Nat

The Rx31-d is straight servo pulses outputs on channels 1-4 with options on the F version of 2 single direction motor drive outputs.
The Rx43-d has the same 4 servo output plus 3 bidirectional motor drives.
Motor drives 1 & 2 are rated at 6V 0.4 A and drive 3 at 6V 0.8A.
If you are going to build a custom motor controller you can use the servo outputs form either receiver and a microprocessor chip to interface to a motor drive chip such as the TB6612 or use the Rx43-d motor drive outputs that will directly drive motor drive chips like the Allegro A4950 chip.
I hope this is of help.

Thank you Peter, you are very knowledgeable across this forum

I will use the board i have, the seller says i can keep it instead if it is suitable.

One other question, i can use these Rx with a 2S lipo? i have a few 350Mah 20c lipo zippy ones, and some single cell 1S ones, but hoping to use the 350.

Thanks

The receiver is only rated at 6v so you will need to regulate a 2 cell lipo (8.4V) down preferably to 5v.

Thank you,
I have a 5v reg which im going to use to power it, just wanted 2nd opinion on the 2S bit
