Pete. What you are describing is a climb at 70 MPH. The engine will then of course get hotter and consume a lot of gas and I assume you will run it at full throttle when climbing. But I am not talking about a climb , I am talking about a slow flight. This is flying at a slower speed by keeping the same altitude. Try it sometime. One does not have to blast full throttle all the time. I usually throttle down to 75% or sometimes even 50% of my throttle setting without having to raise the nose of the plane much or lose so much speed that I am afraid the plane might sink like a stone. When at cruising altitude I target a speed between 90 and 100 MPH and set the throttle for the speed. The engine will thank you, overheating in summer was never a problem to me and the coupe flies and handles as usual, just a few MPH slower - your mileage increases a lot though..
