Yes,RCP supplies the track for Kyosho. The Mini 96 has 96 tiles as the name suggests but two “L’s” only has 86 tiles I believe....do they offer “L’s” with 30cm tiles?

As far as extension packs go that is up to you and the space you have. I personally don’t see the M96WC ever running a track with extension packs because that would exclude people. I kept a number of both outer and inner squares from all the track I gave away so at some point I will personally build a track on our deck that has a fairly long straight 3 tiles wide.

Cheers,
Jim.
