EAA Experimenter 11 BIG BORE ROTAX IS the nickname for Rotax 912 series engines that have been modifi ed to pro- duce more horsepower with larger cylinders and pistons using an aftermarket kit called the Zipper 1484. Hal Stockman of Elko, Nevada, the person behind the upgrade kit, brought his RANS S-7S Courier that he calls the Super-7S to EAA AirVenture Oshkosh 2014, where it was displayed and fl own from the ultralight/ lightplane runway. The S-7S was built espe- cially for short takeof and landing (STOL) performance. The engine had 200 hours on the new cylinders and pistons when Hal arrived in Oshkosh after the 1,400-mile fl ight from Nevada, and he had logged 320 hours by the end of 2014.
