operating temp for OS 50Hyper engine

[vintcs77]

Hi, anyone know what is the operating temp for this engine?

I try to keep mine under 200F as measured in flight with a venom temp gauge, you can probably run it at 220 but thats no room for error.

Andy, *where* exactly do you measure?

Thank you very much for clarification!

Cheers,

Daniel

Where the blue fins end and the case starts. My inflight is looped around the head right there, if I use a gun i shoot it right about the same place.
