I'm sure this has been asked, but here goes. I ususally hang out in the slotcar forum have 2 ho scale portable tracks and a 1/43 portable track, which leads to my questions. I use my tracks for birthday parties, cubscout events car showes and so forth. What would be the best mini rc to do birthday parties with? X mods, Mini z, Mini t, Micro t Or brp? would the larger 1/18 scale be better or the smaller scale. Want to make it portable and all of my slotcars are dirt track or nascar themed. Also a good radio system? I think I have a handle on track contruction from the previous post. thanks in advance for any help, hope I didn't open a can of worms. If you ask a quetion like this on the HO slotcar boards you start a war.
