Ok that's more great info and I'm learning from this stuff thanks! Great to have this assistance in avoiding some of the packages I might end up regretting.

I might message the seller and ask about the PSU thing.

In respect of the drivers and the current they can output & the rating of the motors, do the motors only pull the full rating when a load on them demands that? Or do they somehow draw that constantly? I'm not quite sure how that works sorry.

Be nice if there's a package at a sensible price that suits the X2 specifically so I'll look a bit further but may potentially come back to this second one. Maybe.
