glow and mix
 

which is the number of glow you advice to me? 3 or 4? i saw that with a glow 5 i have a lot of switch off and i don't know if this is caused by fuel (16%nitro) or by glow (#5). I remember that when i was doing the running in i used the glow number 3 (gave by CEN) and i haven't any problem....now, with a #5 i have a loto o fprblem with the tune of the engine.
and the mix? 16% or 20%

thanks
cheers by italy

lambo- run a Cen #3 or OS #8 both are warm to hot plugs that 5 is a cold plug and you will have to retune the motor for it and i recommend to use 20-30% nitro the motor will run much better
