While 'chasing the tune' through the excess heat I incurred, my plug got 'unhappy' and taxed my igniter' to the point I had to go to my more recently charged 'backup'. After I got an excess heat indication on my plug, I did change it but more of my problem was in the igniter power making me think I had another issue. I kept the same heat range plug but found the richer tune I needed for the engine to be happy.
Jerry my igniter is a Prolux Lipo-glow and it is fully gharged.The indicator of condition of the glow plug shows that everything is ok. It is strange because having the plug on my hand as brand new i saw that it glows normally and after the problem appeared it didn't glow. I just could feel a little heat in my fingers.
At the same moment another brand new plug glows normally.So it is not a case of the igniter. I was afraid of the bigger percentage of oil that was included at the fuel. So i turned down at the normal percentage of oil.
At least the break in procedure is done and the engine is properly tuned.
I didn't change the place where i run my model and i believe it is properly tuned. The temperatures looks perfect at my tempgun. Never exceed the
95 C at the base of the glow plug and the 105 at the side of the crankcase.
The lowervalues at the head are thanks to a bigger head of Fioroni.
By the way i hope with a normal tuned engine nowafter i won't have problem with my plugs in the future.
But just in case i would like to now the models of plugs you use as an alternative of T8CGH
