Al,

I can now see why some of the big boys (Like Mistral) are playing with the 20B. With the extra power available the cruise is still pretty good, it sounds sweet as well. What are the draw backs?

Subject: [FlyRotary] Fuel burn

I’ve finally got the EM2 fuel burn pretty well calibrated, and took note of some readings today.

At 7500 ft I was cruisin’ at 200 mph (TAS) at 20.7 mpg, 9.6 gph (average of two readings). MAP at about 17.2. One reading at 8500, same speed, of 21.2 mpg. This 20B is better on fuel than I expected; I like it!
