Will double check. Switching between 2x12 working and 2x5 not. Dip switches the same on both. Will see what comes up. Ty

Hi Tom, hard to say. As the help pages in OP Config describe, you should set the Serial 2 baud rate to 38400 if it is not already (see the Misc tab). That is the default value and I don't know why it would have changed, but double-check it. If it was something else, make sure to write the settings to your TCB after you change it back.
For the Sabertooth 2x5, there is nothing else you need to do about the baud rate on the Sabertooth itself, just make sure the dipswitches are set correctly.
Check all the other usual things - Sabertooth really selected for drive motors in OP Config, you really did turn on the engine from the radio, the transmission isn't disengaged, etc...
As usual, you'll have to do more troubleshooting yourself to figure out what's going on. I'm sure it will end up being something simple.

I have a few Sabertooth 2x12's and one 2x12 RC version and all working fine. I got a 2x5 non RC for a light tank but not working?
It is wired the same way as the Non RC 2x12. Dipswitches same. The Saber power is on, steady blue light but no drive to motors. Can't think
what it could be? Baud rate maybe (?) but not sure what to try via settings. Thanks.

Hi Front, that looks good, thank you for sharing. I've added your files to the Downloads page under the Accessories section.

Hello everyone. I’d like to share a case design for the Open Panzer mainboard. The case was created using Flash software. It works perfectly for me. Best regards.

Glad to hear it, thanks for letting us know.

It was settings on the radio. I little tricky to flash the right(older version) firmware on the x8r but now all works.
I had a feeling it wasn't an issue with the TCB as half the triggers were working.

Slight correction, I read the radio again and "Both sticks" trigger just can't test the right stick unless engine is on.
Flipped all the other switches and nothing reads. So, I reached out to Ben to see if he has any other ideas.

Thanks Luke. On read radio the only triggers that show working are left stick. So for instance the turret moves and sound triggers. So it sounds like something going on with the transmitter/receiver. It is bound but not fully working all the triggers as the X4R is. I can try to reach out to Ben but I am not sure at this point he knows what the problem could be. Thanks though

Hi Tom, the X8R has been used by quite a few other users on this forum with success, so we know it is possible. There are however as you have found discrepancies between the different firmware versions that FrSky uses and there are multiple posts of people having issues getting that all straightened out, which I suspect is the case here as well.
The first thing you should do when there are radio problems is to run through Radio Setup once again. It could be that channel orders have been changed under the new firmware, or something like that. But at any rate, Radio Setup will show you visually and immediately which channels are being read by the TCB and which are not. If it's simply a channel order problem, then you can re-arrange them.
If some channels are not appearing at all, then I think the issue is likely between the transmitter and the receiver, or with the setup on your transmitter, and that I can't help you with, but perhaps your contact at FrSky can (who I see is also a member on this forum, so perhaps he will chime in).
