Just got a .21 full modd today and will be testing it tom. I noticed no plugs came with it, not even the 1 that was used to "break in".
I'll be using 25% and not 30% nitro...availability issues. Weather at around mid 90's, humidity 90sh%, 25mtrs above sea level (dunno if that matters)
Should i adjust head shimming to compensate for the lower nitro content?
What plugs to use in these conditions?
Any suggestions guys?
Thanks in advance!
