Thanks go out to GAfuels reader Michael Gallagher of Peoria, Ill., for sending us this story on his recent long cross-country trip in the mogas-burning, Rotax 912ULS-powered RANS S-7S he built himself:
“On June 19th, I loaded up my 2011 Rans S7S with luggage and my 5-year-old son/co-pilot and took off from Peoria, Ill., (KPIA) for Syracuse, N.Y., to spend a week with his grandparents. The tanks were filled with 27.5 gallons of 91 AKI mogas and after a mid-day fuel stop at Wynkoop Airport (6G4) in Ohio for refueling with 100LL we were on our way again. The unfortunate choice of 100LL was due to the lack of any 91 AKI mogas anywhere near my route. After seven hours of very smooth CAVU flight, we arrived in Fulton, N.Y. (KFZY). Carrying three fuel bags from Alaskan Bushwheels made refueling with mogas easy to fly family around upstate New York and to fill the tanks for our return trip home.
Little did I know that the weather patterns would conspire to keep us prisoners for a total of 17 days. Weeks of rain and low IFR persisted until a fateful day in the first week of July; we were sprung from our soggy retreat. The flight home was almost three hours longer due to winds aloft, three stops to check weather and plot our next detour around rain and, of course, fuel.
When weather ahead and no cell signal for weather on my iPad prompted our first stop in Jamestown, N.Y. (KJHW), the route was adjusted for weather, and again in Sebring, Ohio (3G6) with a fuel top off of 100LL. A few dog legs later to avoid rain cells I was about to call it quits for the day when sunshine and great visibility appeared on cue over Marion, Ohio. The final leg home was smooth sailing with a quick refueling stop in Logansport, Ind. (KGGP).
The use of Decalin to help with lead deposits from 100LL helped, but the filthy black appearance of the oil after using several tanks of 100LL prompted an oil change upon our return home.”
