We all know how fast these wonderful machines can go, but they make wonderful slow speeders too, at least with regards to fuel burn. Today, while putting around the area in my RV-7 equipped with an IO-360 with LSE and one mag, I pulled the throttle back to 15-16 inches, prop at 2400rpm, and leaned to the lean side of peak (LOP) at 4500'. I was indicating 120kts, my Dynon was giving me a true airspeed of 130kts, and my fuel burn was barely 5.5gph. Pretty amazing.
