Good news form North America. Jim Butcher. Europa Monowheel builder and pilot .
"..........We can’t tell any difference in using it compared to gasoline purchased from an automotive gas station. The biggest problem with it is that the number of places (airports) where it is available to purchase is quite limited. Swift is just a part of a larger situation in the US trying to come up with a replacement for 100LL. There have been government sponsored programs for over 10 years, and a new program was announced a couple months ago with the goal of a replacement by 2030! "
