ok...someone plz explain to me
from reading all the forums on net....i saw lots of ppl said keep your engine under 270 or 260f
but
i have a kyosho GS15R and GS21R...
both engines will like to run around 280 to 300f...and still got lots of blue smoke..
if i tune it around 240 to 260...they run kinda slow....
so should i keep it around 280f?
or these engine meant to be run SLOW?...@_@

thanks
