REFLECTOR: One hundred miles per gallon

[Chuck Harbert]

I talked to Steve M about our flight and he (and I) were really is impressed with your plane, especially how you can lean it below peak and still have it run so smoothly and get great mileage.

Thanks again for the ride.

Chuck;



That's pretty amazing - I was going to say "unbelievable" but I guess I do believe it.  But he flies alone in what is realistically a single place airplane; and has spent most of his adult life making it efficient.



I think if I slowed down to about 125 kts, and leaned aggressively, I could get 30 mpg - and I think I have 3 times the airplane he hasJ.  I need to do some more adjusting on getting the EGTs the same at lean cruise conditions, and I haven't played with the timing at all; which is something I can do from the cockpit in-flight.



BTW; regarding the VGs - it's OK to put them on the wings, and not the canard; but not vice versa. It actually reduces the chances of deep stall - reduces the stall speed of the wing.



Enjoyed your visit on Sunday.  Hope the bounced, crooked takeoff didn't scare anybody. I wasn't concerned, but I thought later that if I had been a passenger, I would have been.



Al
