Hi. I visited Keld yesterday, and had great fun. I'm NOT the guy making upgrades for this ;) I found the cars perfect balanced, as they are. Super-hubs made for performance would simply be overkill to the entire concept. If (and when) I make some, because I have too :) I will go for a dual o-ring so...
Just a thought....
Would it be possible to route a ex. 3x3mm slot, fill it with magnetic filler, sand it, paint it, and then have a smooth surface track?
I'm not going to the shop until april 2nd, nothing can be done before. I still haven't seen a car IRL! Could the Slot.it series of tyres be used, or are we talking a totally different compound? I have tools for making bores from ø1.5mm, and could plan to make some for testing, but sparetime is REALL...
