This morning a friend flying an Ercoupe and me in my RV9A flew to a fly in breakfast. I wanted to stay close so I throttled back to just under 1800 RPM and 92 kts. to match his speed. I was burning 4.2 gallons per hour. It was a short flight of about 25 minutes. Is there any problem in running the engine at a speed that slow for short periods? My engine is an E3D 150 HP with fixed pitch prop. All the temps were in the green and the engine seemed smooth as silk.
