Thanks Don. Very interesting stuff. I was wondering what the 2000 hrs would equate to in mileage on a car. So for example I would be doing a rebuild every 30,000 miles? I know that's very subjective but was just interested in some sort of comparison. I guess with the info you have provided I can think about that while I watch the cricket this arvo.
I had wondered that but I see aircraft sitting on the infield at throttle for considerable time. Are they all air cooled?The post-overhaul ground test tends to be brief. Aircraft engines are air cooled, so running them on the ground for too long can do damage.
