Wobbly robot. Please help, I’m going mad

Aaaand factory reset has changed nothing. I’m genuinely out of ideas

I believe the Malenki Nano is set up to do 50% mix on the steering by default, have you tried setting it to the maximum 100% (number 11 on the list)

I hadn’t, I’d only turned it off (6). Don’t know how I didn’t see that one, worth a go

What does it show in full reverse? Do you have a couple of servos you can plug into a receiver on channels 1 and 2?

Full reverse looks like so.

I don’t have any servos that aren’t soldered into things atm, but I might order two of those little plastic blue ones for a test

Ok, I’m going to lay out data for anyone who fancies reading this, in hoping that the scientific method helps. Three robots, how they drive, and the components they have/have had. I’ll also list two other robots.

Worth noticing that the robots with steering problems have had these problems with any of the components they have used.
