Regarding a sandpaper truer, above the power supplies is a simple “tire cleaner” – a piece of carerra track with #300? sandpaper on it. We use if for minor clean-up truing between races, and for HO cars. I made it back in May when Bobby was taping paper onto the bench and truing his tires that way.
Regarding the Razor, I bought Dave’s and adjusted it to make it actually level (it was not truing each side equally). Mine works Ok – yes Ary it’s not a precision tool but for carreras it would be ok.
ALSO – why dont we just allow Slot.It axles, wheels and 12mm tires? I converted my Carerra 2016 GT40. It is still Heavy and we should consider a Slot.It Orange endbell motor. Everyone has spares and those that dont can buy parts from another member.
