Totally & completely agree with good CHT and infact I have been using KSA CHT1DT which gives it digital on 2 cylinders has over temp light which I set for 175°c & have used in motor gliders for 7 years now. It also has shock cooling & I set for 20°c/min (factory data in USA says max 40f/min) They were $400 but Bill Simkinson now mid 70s has retired regretfully in SF Bay area. I have sold about 30 of these to most clubs for Pawnees etc up and down the east coast of Australia.
Regretfully I need to look for something new but been talking to Ian Bent & said consider it an insurance policy one off payment on engine. With our h36 I discovered there was air flow from left to right side of engine thus I added a division down middle of engine to make air going in LHS work harder. The DA 20 single engined Diamond has Lycoming and has much bigger hole on upwards going blade to downward going blade. In the early days of towing with C180 s 2 years later there were cracked cylinders everywhere. Remember VH-WIT had 4or 5 cracked cylinders. Bob how has your C180 going? Currently am thinking EI ultimate scanner or JPI (too expensive I think) or one made in Czech Republic and another I saw in bear hog at weekend MGS. Anybody got suggestions?
