Sorry to hear you missed out on the event.
Aye, there'll be other events. Just a case of bad timing and missing parts. I've got Azriel running and will update tonight on that.

The 2 motor/1 wheel thing does look a bit awkward. What's the alternative? 4wd? Or bigger motors?
4WD isn't possible with the tooling I have here (I lack heavy duty stuff to cut through the steel efficiently) and the lack of wheels and drive gears. Kaizen used a independent 4WD setup which wad dead simple but the space requirements means Jibril would need a belt or chain drive to the wheels, none of which I have the equipment for.

I considered getting a pair of Ampflow motors but that means more expense and a new set of drive gears. I could theoretically go brushless with this but for the moment, the 2x motors I do have and can fit should be enough (they are nominally rated for 330W but 500W a side should be enough, Kaizen was 800W at best). I think I might fit some small fixed castors at the bottom to over come the drag. Just got a lot on before RL Burgess Hill at the end of March.

I still think, with a bit of ingenuity, it will be possible to fit in the second set of motors.
