And yeah that should be possible. I don't own that transmitter but the setup you want is a pretty standard mixing setting.
If, for whatever reason, the transmitter won't do what you want, you can install a plug and play mixer between the ESCs and receiver in your robot and leave the transmitter unmixed for the same result.
Hope it works out

I got a separate mtronics tank mixer for about a tenner - tiny little unit that just plugs between the receiver and speed controllers. Only had it running with test gear so far but it seems to work great.
Thanks. At the moment I have it setup like so.
Motors/ESCs connected to CH1 and CH2 (right stick)
CH1 (up down on right stick) is mixed to CH2 so up down controls both wheels forward and back.
CH2 (left right on right stick) controls one wheel but I won't use it.
CH3 (left right on left stick) is mixed to CH1, so when I turn left the left wheel goes back, when I turn right it goes forward.
How would I use the plug and play mixer in amongst that setup to get CH3 control both wheels, turning in opposite directions?
I haven't tested if it reverses one side in a turn. The point of little units like the mtronic is that there aren't any settings to worry about so I would imagine it either works or it doesn't.
Might have everything running properly at the weekend, so will check then.

A plug and play mixer would require no mixing on your transmitter, with channels 1 and 3 on the transmitters directly controlling the 2 used channels on the receiver.
I know it might be cheating but could you get hold of a ready to use V-tail mixing model for your tx? That would get you there straight away.
From the sound of it the physical mixer is just going to do what the program does.
I need to get ch3 left to control ch1 forward and ch2 in reverse, and ch3 right to control ch1 in reverse and ch2 forward.
So I think I'm trying to split channel 3 into 2 channels, with each one controlling the 2 in different directions. If that makes sense.
Maybe it would be easier to have each stick control a wheel and then I could turn by having one up and one down. But the left stick doesn't return to centre when released like the right. It sits where you leave it and it's not easy to centre without looking.
I'll look at what the v tail mixer does.
That wasn't very clear of me. I meant - there must be a default tx programming file available somewhere with V-tail mixing taken care of. I'm not an expert in the slightest in programming that tx but I thought it might be a shortcut worth tracking downI know it might be cheating but could you get hold of a ready to use V-tail mixing model for your tx? That would get you there straight away.
Getting a physical mixer might be a bit silly as you say.
After looking a bit it looks like it's possible to mod the left stick to make it sprung, which will mean I can just operate each wheel sperately and I'll then just move them in opposite directions to turn.
Thanks for the help
