Aircraft engine giant, Rotax BRP has reached an anniversary: forty years of making powerplants used around the world by airframe makers of ultralights to Very Light Aircraft. Thus, it was hardly a surprise when Light-Sport Aircraft came along eleven years ago that the Austrian company immediately became the largest supplier of engines … capturing an estimated 80% of the market, even while other ASTM-approved engines are in use from Continental, Jabiru, Lycoming, and HKS. New candidates include Superior’s Gemini Diesel and, of course, the ECi Titan 180-horsepower engine has seen good acceptance. Then we have another batch of engines for kit-built aircraft including Viking (based on Honda), UL-Power, AeroVee (VW), AeroMomentum (Subaru), Corvair, and more.
Despite the many other choices, Rotax has retained a dominant position. I’ve long felt that while it can be challenging to bring a new airframe to market and win some customers, it is even harder to introduce a new engine.

Some people, myself included, love soaring flight. As the following article from Dave Unwin explains, to use his words, “Soaring flight exercises a fascination that is both difficult to explain and hard to resist, sometimes called ‘three-dimensional sailing.’ Flying a heavier-than-air machine for several hours and hundreds of miles by using the atmosphere as the fuel possesses an undeniable attraction.” As he further explained in a longer article, the downside is getting airborne for soaring flight. Various alternatives have been explored. Some were reasonable; others were too marginal to be enjoyed. In the following piece Dave tells about a new aircraft that might solve this problem, one that can fit England’s innovative SSDR 300 (kilogram) category. —DJ

Article Updated 6/17/15 — ProAirsport announced, “We have now released a priority price of 39,950 British pounds (about $63,000). More details can be found on our website.” This is an excellent value for a motorglider.

Let’s set the way-back machine to two dates and examine the actions of our good friends at FAA. One date was September 1982. Another date was September 2004.
Date #1 was the time when FAA announced Mike Sacrey and team’s remarkable Part 103. This rule has lasted for 33 years and continues to hold interest (see earlier article on the subject). Date #2 was when FAA announced the SP/LSA rule engineered by Sue Gardner and her team. I continue to applaud their initiative for both simplified rules where they stepped far back and let the market do its magic. Both have increased the freedom of pilots to fly what and how they prefer. Kudos, FAAers!
Part 103 is strictly single seat since the two-seat “103 trainers” were forced into ELSA status. Does a market exist for one-place aircraft? I always cite this survey result from AOPA. After many years of asking, the big member group determined the average occupancy of a GA aircraft was 1.6 persons.

“So, it looks like Rotax has finally got some worthy competition,” was a comment I received as I walked into the Sun ‘n Fun press headquarters work room. The observation came from a fellow journalist at one of the big aviation magazines. He is aware Rotax dominates the light aircraft market with an estimated 75-80% of all engine installations, even higher overseas. Who is going to give the big Austrian engine manufacturer some competition?
Superior Air Parts got started back in 1967 making components for certified engines such as Lycoming but long ago branched into their own engine line. Companies like Arion Aircraft is using an Experimental Superior XP powerplant for their new EAB speedster similar to but quite a bit faster than their LS-1 Light-Sport model. Like Arion, many already knew of the gasoline engines from this Texas company, but I knew something was up when I was approached at Sebring about a new project.
