I know what you mean, I am still smiling! I certainly did not buy the Syssa for fuel economy on an Extra, but damn, this thing gets great gas milage! I have a 24 oz tank on that test fixture and it takes along time to empty it. You can almost justify the cost of it on the fuel cost delta compared to even my OS 120AX with alot less thrust. Also, I was blown away on how easy it is to start and run, you certainly do not need an electric starter.
