Anyone know how hot an LA25 on a profile gets or how hot a (stunt) model engine in general gets?

Which part of the engine?
Methinks that a plain bearing big end would one of the most critical parts so how would one measure that?
Oil breakdown is the key I suppose as any meaningful measurement comes from lubricant temperature.

If you are really into the gadgets, R/C car guys use these.

I bought one with the intent on using it. Never can remember to dig it out when flying. Yes, it is a neat gadget & fun to play with. Seems surprisingly accurate. Perhaps I can remember next weekend & give you a reading from an OS 25 FP.

Hi M.M. Dan Banjock uses one of those infared devices when he runs his in-line dual Fox 35 set up. It is very accurate, he aims it at the head and tweaks needle valves til both heads are the same temp. I watched him do it but for the life of me I can't remember the temp. Sorry if I got a little off the original question, it was more a plug for the infared sensor. I think it might have been in the mid 300's? That's just a guess. I'm sure one of the motorheads will have a better answer.
