Fastrax King Kourse, stiffer front springs, re-programing of the speedo, , and getting more teeth in, all very much an improvement, a little slippy today, but it was getting to the stage of being very drive-able.... although completely at the mercy of random events once airborne...
Underbody is essential, I think i have cleaned the entire track of loose astro, its now on my office carpet if anyone wants it back...without one, I think it needs drain holes, and cast iron covers in the chassis
OOOooo and nice to see a 2nd SC doing a tour at the end too....
