What do you guys think is the optimum temperature for our RC engines to operate at?? It seems like the best place to measure is to point the thermometer down at the glow plug (closest to the head Temp). Would the optimum for a 2-stroke be the same as a 4-stroke???
Someone published an article on 4 stroke engines in one of the latest issues of the RC rags( I can't remember which one at the moment) .
In the article, the author measured the exhaust temp with an EGT probe of various popular 4 stroke engines with various configurations and fuels, and the numbers tend to be around 500-550F.
I found it rather interesting that the author compared EGT reading for castor and synthetic on the same engine with same settings and found the engine actually ran slightly cooler with syn fuel.
