Yeah, that's my worry with going smaller, Nick - I've learned that in a roundabout way with wheels too!

I'm more than happy to amend the motor too depending on what I can find/afford (got to get a working drive system/battery and this done for £250-ish at the most) but I think that may be a nice starting point - after all, I'll be pulling the most current on startup I'd imagine and 2.4kw sounds like enough. Of course, I've not a single clue as to whether this is actually enough but the potential for overvolting may make it more viable. Could be worth a few experiments at least if it comes to that!

That bar was insane too Sam, I did measure the dimensions you gave me for the machine against HardWired, and you've either built a feather-size beetle, or I've built a beetle-size feather haha
The idea for the disc was basically along the same lines as Rango/540 used their spinners, drive being the focal point and then the spinner being there to add just a dash of chaos into the mix haha. After seeing the hits that Rango and 720 got this year though by driving into things at relative speed, I think the engagements it could make at high RPM might potentially be utterly insane... but time will tell!
