I would love to be able to read exhaust gas temps or head temps in flight........ Lots of talk here about 180 degrees........200 or so. I put my infered gun on my Stihl leaf blower during a 10 min full throttle run right at the base of the plug........310 degrees and running great. DA 50 is always 160 or so at the same spot after a full throttle run then landing.....sure it cools down some....
