well my first time out with my tc4 (i had not driven on-road in two years) i was racing against x-rays and tamiya 415's and came in third place.first place was a losi,second was another tc4....pretty much the rest of the field was made up of the x-rays and tamiyas so i would say the tc4 is a good car...the only thing i put on my car was ti-turnbuckles and a one-way. everything else is stock.
