Hi All. I have ordered these below. http://www.aircraftspruce.com/catalog/inpages/dUALCHT_gauges2.php?clickkey=2892628
http://www.aircraftspruce.com/catalog/inpages/smicroprobes1.php No need to do calcs in my head as to true CHT anymore. Plus I can read left an right side at the same time. Unfortunately it is not in Celsius but I can easily deal with that. Just add a red stripe to the gauge face at the appropriate point. Remember the MAX CHT on climb should be no higher than 180 c and 160 c in cruise. If your valve clearance is closing up at each 50 hourly it is an indication your engine is running too hot. Cheers. Nige.
