After a 3+1/2 month hiatus, finally got back in the air today. Had a great flight. However, this was the first time I have flown above say 45F. It was 75F and I noticed my cruise coolant temp was a bit higher than anticipated (170F). Coolant level is full and thermostat is operating fine (opening at 140F).

This is a Kitfox III, 582 Rotax gray head with belly mounted radiator. I was hoping to see maybe 150-160F or is the 170F typical? Concern being how much worse things might get on a hotter day.

Running the recommended 50/50 mix. Less than 50 hours on all components.

Anyone run across this before?
