Here is a vid of two ZX1.5R's running at one of our many local tracks, WOW (Way Out West), First day open with new track layout. Just messing around practicing. These are non-team drivers who race them. (I was taping). Some pretty good crashes getting used the track and no breakages at all and they kept going strong all day. The 1.5R is an extremely tough buggy.
