DX4S Programming

[kam2040]

Dual ESC crawler setup:

Plug one ESC into AUX 1
Plug other ESC into AUX 2

Front Dig:
In the List Menu scroll to MIXING, then Select MIX A, Set master to TH, Set Slave to AUX 1, Turn trim on, Select which switch you want (ex A), Set Value A to 100%, Hit switch set Value B to 0%. Go back to list menu scroll to Switch and set a switch (ex B) to MIX A Rate.

Rear Dig:
In the List Menu scroll to MIXING, then Select MIX B, Set master to TH, Set Slave to AUX 2, Turn trim on, Select which switch you want (ex c), Set Value A to 100%, Hit switch set Value B to 0%. Go back to list menu scroll to Switch and set a switch (ex D) to MIX B Rate.

Now you have dig as well as front and rear proportional.

Thanks a million for posting this
I screwed around with mine for over a week and still couldn't get rear dig
Shows you how dim I am
I guess I should be glad that I'm not clear burnt out
Tell Ryan and/or Brian that I said they should buy you a beer for figuring this out

[KBrog]

Awesome! Thanks for the info.

[chevotafun]

Ahh interesting so it is possible to do that with this remote,
one of the reason why i didn't want to buy one thank for the info

[grunt95]

yah someone cracked the code! Finlay i get go buy mine now, thanks for the info Sir.

Good post Kam! I take it you got Scotts truck up and running?

[TJ Steve]

It def works I just programed mine! I don't know how the Futabas work but this takes four buttons to work, but it does work. Thanks Kam

[grunt95]

how easy is it to use i would think having four buttons would be a pain? Also could you just get rear dig this way?

I think after a little time it will be second nature, depending on how much you use it. Yes, you can just set up one axle to dig, with proportional adjustment.

Just a quick question but i,m wondering if the same steps could be taking to get the propo dig working on my novak m2. Right now i have front and rear dig but there is a propo mode on the esc, and i couldnt figure out how to set it. ...thanks....

[TJ Steve]

Sorry I can't answer that, I've never owned a Novak. I got three Tekins but, I didn't have to program anything into the Tekin. I think this would work with any ESC, but I could be wrong. I believe it is all controlled by the receiver, if I'm understanding this right. Then again, I couldn't figure out how to get both axles with dig. (I was close though)

[donzx12]

great help thanks.wish i could set front dig and rear on one 3 position switch.

[darkangelv24]

Is it possible for someone to take a video of the end result of the programming so i can see which buttons you use and how it all works,

Something similar to this which losikid did for the gt3b
GT3B Hack w/ Dual ESC Control - YouTube

otherwise could someone do a couple of pretty pics and some explanation?

Looking at getting a new TX and was hopeing this might fit the bill, otherwise im getting a 4pl.

Some more DX4s ideas/tips here... Spektrum DX4S Thread

[MoFoHo]

Hi all. I'm considering this radio as I'm currently working on a superclass rig. I need 4ws and front dig functionality...

Thing is, the ESCs I have. (Enroute A4) The drag brakes are engaged manually by engaging reverse immediately after forward throttle. So for front dig to work, I'd need a mix that can provide a reverse signal proportional to the forward signal, accessible at the push of a button. I'm sure my Futaba 3PK can do this (I just set the mix at -100%), but I really need a 4ch as I also wish to use full control of 4ws.

Could the Spektrum DX4s be suitable? Can that rear ESC mix, be programmed to either simply mirror the front ESCs output, or provide a reverse of that signal?

I hope you guys understand what I'm trying to explain!

Just to say a big thanks to KAM2040, the steps above work a treat for setting up a twin esc crawler, picked up my DX4s on sat and took 10 mins to program with these steps. easy as pie.

MOFOHO,
could you not use the trim to ensure the throttle is set slightly to reverve to ensure the drag brake is always active when not accelerating?
So the dx4 already has a 4wheel steer mix set up so that bit is sorted.
There are two user programable mixes aswell, i am a little clueless about mixes and how exactly they work but i think from what you describe the mixing should sort this.

You can only program the esc to dig or propo not both.

I take it the BEC plugs into the Throttle channel (2) then?

[skyraiD]

i just ditched my DX4S for crawler, this radio has been so bad to get it going. can't get it to work like it should , just ordered the Futaba 4pls

scratch the Futaba 4pls going to return it.
