Found out why the drive on one side locked up. A collar on the pinion gear that holds the gear from popping out of the bearing broke off and went into the armature and the jammed the whole show up. Dinged up a few of the leaded plates on the armature, so I have removed the motor and left the mountings and the bearing block to run the wheel as a castor. This seems to work fine when spinning, and works just like the 1 wheel version, but spins up on the spot instead of eliptically wobbling around till it gets up to speed. Now that I'm back to 1 drive motor, the voltage is going up to 39.6v like in the testing after RoboWars.
Found half the problem with the translation not working, I found that somehow the model programming for MBX in the spectrum had activated some wierd ass mixing of several channels, and I couldn't remove it (I can't find the manual to read how), so I made a new model settings for it and it seems to have fixed half that problem. Just need to work on calibrating the parameters of the accelerometer now to get the heading LED to work correctly.
Things are looking less bleak, so hopefully tomorrow I'll have it running right, I'll bring the old version just in case _________________ https://www.halfdonethings.com/

Thanks to the SSR group buy, I got MBX running again today. Not after a few dramas though, the winch motor that took the flogging from the fused on SSR seems to have melted the insulator washer between the comutator and bush, and when I first fired it up, it spun rather slow while giving off a lot of smoke So swapped over the spare motor and it ran fine.
I took some video because none of my other videos show a much of it actually driving, and it hasn't had very many battles where it functioned correctly to prove it. So I got some clips of it actually driving around the garage, still a bit sketchy as I'm running the manual header code at the moment. I was going to have the accelerometer working this weekend, but I've left it in a box at my parents place, so need to pick that up next weekend to get it going
Anyway, proof that it does work
