should i run 20% or 30%?
i have a nova 21-3port and a mach 26 that run great on 20% in my 8ight truggy...people tell me i should run 30%...i was just wondering if the higher nitro content will shorten the life of my motors?....if not then what shims should i use to run 30%?....ithink both of these motors were already ran with 30% cause i got them used from serious racers...i want to be as competitive as possible but dont have $ to replace internals any sooner than i have too!...as they are usually expensive
