OS glow plug temps

[Tim Schaubroeck]

Hello,
I am running a Sirio .12 Roar legal motor in my Nitro TC3 with
30% fuel. I need to buy some new glow plugs and my lhs sells OS
plugs.
I have found that the #8 is a medium plug.
I have found that A5 plug is slightly cooler than the #8
The R5 is listed for high nitro, high rpm, but it does not
state its temperature. What is temp of this plug in comparison to the
8?

thanks,
tim

Its a colder plug. If you run a hot plug with high Nitro, it will overheat
real fast. Plus the timing changes.
