Hi Guys, Do any of you select your glow plug based on air temps as per the nova temp chart? Reason being, I had a flame out which cost me 4 places when my gut feeling said change from C6 to C7 due to high ambient temps. After the race, i spoke to a few guys who also run Nova and one said they never select plug based on air temps and he would have run the C5 in the hot conditions. The air temp was around 28 deg C so borderline on C6/C7 plug. The guy who ran C5 had a few flames himself... any advise?
