All of these shops overhaul certified engines as their bread and butter business, but they have their own line of special parts and hot-rod knowledge even the factories likely dont possessideal if youre looking for something special, racy, or show-worthy., Other shops are far more local, ranging all the way down to one-man-in-a-hangar operations. In the not-too-big, not-too-small radial category is Australian engine maker Rotec, which continues to supply the most round motors to the experimental market. Of the engines offered, all use parallel valve cylinders except the 390 and 580, which employ angle-valve cylinder heads. There is no TBO! This is the main reason why two stroke engines must be overhauled at more frequent intervals than four strokes: They simply work harder. The originals were pretty high compression engines to begin with, so the current six cylinder is good for about 210 hp. There is no shortage of partsat least most of themaccording to Franklin Aerospace. Also stock is Continentals nickel-carbide cylinder treatment (NiC3) for better durability and corrosion resistance. . A closer look shows the AX50 cylinder is a single aluminum casting, rather than a separate head and barrel joined together, and a removable sleeve is provided for the cylinder bore. -. All ULPower enginesboth the four- and six-cylinder unitsare electronically fuel injected and sparked. To provide slimmer packaging, Plumb has spent the last two years redesigning the oil sump and case to accommodate the intake runners. This engine embodies innovative technology and features which provide high output, low fuel consumption, and extremely reliable operation in aircraft service.

In the meantime hes gotten all the Corvair teardown, operation and other manuals online for everyones free use. At least in their technical specifications, these engines are suited to larger homebuilt aircraft. The smaller engine is most often paired with a fixed-pitch 76-inch-diameter prop while the R3600, which was later to market but seems to have picked up sales steam lately, can swing 90-inch blades. This gives simple, check-the-box shopping for RV engines, albeit just in the configuration suggested by Vans. Lycoming says they have three such build teams working and need to add more, always a good sign. By comparison, the 914 will save you about $7,000 in trade for carburetion and a maximum of 115 hp; the 914 has a TBO of 2000 hours compared to the 915s 1200 hours, as well., If the all-singing, all-dancing 915 Rotax does offer some interesting performance capabilities to anyone interested in zipping along just a bit shy of the flight levels, its worth remembering even the entry-level 80-hp Rotax offers aviating for notably less than half the money and in a definitely less-stressed, should-last-forever package. , Superior Air Parts comes to engine building from decades of building aftermarket replacement parts for popular engines, especially Lycomings.
