Kitfox Aircraft has become one of the first aircraft manufacturers to fly Lycoming’s new O-233 powerplant.
The Kitfox S7 Super Sport – now in test flights – features Lycoming’s new 115-horsepower O-233 with a Champion electronic ignition system.
“We did not want to release information until we were sure we were ready,” said John McBean of Kitfox Aircraft. “We are excited to be one of the first flying with this new Lycoming technology and we look forward to showing the Kitfox S7 Super Sport at Oshkosh.”
During EAA Airventure, Kitfox will show the S7 Super Sport at the Lycoming display, the big red tents at Booth 277-282. Kitfox Aircraft will be in the North Aircraft display Booth 634-635.

Hmmmmm…. this press release says it is experimental, yet Lycoming’s literature on the engine implies it is intended for LSAs, which are ASTM compliant. Maybe we’ll learn more at Oshkosh, Jon.

How is the engine certificated? Experimental, Part 33, ASTM?
Great news, John! Make sure you tell everyone that this engine is certified to operate on lead-free, ethanol-free autogas, saving its owners $1 or more compared to 100LL.
