About Us

Welcome to the Advanced Powerplant Solutions website. Our mission is to help our customers enjoy the sport of flying by providing parts and services to Ultralight, Light Sport Aircraft and Experimental Aircraft Owners at competitive prices in a fast, efficient and professional manner. We have done so for over 40 years and hope to grow with this rapidly changing industry.

Leading Edge Air Foils (LEAF) is one of the oldest and largest suppliers of ultralight parts and accessories. LEAF was founded in 1975 by Bill Raisner in Peyton, Colorado, and as most aviation enthusiasts remember, Bill passed away in 1999. LEAF was sold to Bill Read in August of 2000 and the business was moved from Colorado to Wisconsin. Today, LEAF operates from a manufacturing and warehouse facility in Lyons, WI located on the east side of two grass air strips leased by Wag-Aero and Aero Fabricators, Inc. If you are ever in the area, please fly in and meet some of our staff.

APS continues to be an independent Service Centre for ROTAX engines and we have experienced technicians available for service and overhaul work on all ROTAX two and four stroke aircraft engines. We maintain a substantial inventory of ROTAX engines and spare parts in addition to many other LSA ultralight parts. You will find that we carry most of what a pilot or mechanic would need to care for their aircraft.

Our goal is to be your preferred supplier of parts and services for your aircraft needs and we hope you will join our substantial list of satisfied and loyal customers.
