RE: xxxnt 60mph
you can go verry fast with a xxxnt stock with the 18t clutch bell you can get close to 45 the biggest cb losi has is a 20 but you can get a ae 22t witch is 28% bigger then the stock 18 that is almost 15 mph put in a .12tz witch revs about 40ks vs the mach .15 about 30ks i think you can get to 60 give or take my xxxnt with a .18tz and a 20t cb flys but any car at 60 + hits anything something with break but you can do it .
