10 Vol.3 No.5 / May 2014 FLIGHTLINE SENSENICH PROPELLER introduced its long-anticipated adjust- able composite propeller for the Lycoming O-360 at the Sun 'n Fun International Fly-In & Expo last month. The prop complies with ASTM standards, and it is ready to ship to owners of Van's RV Models 3, 4, 6, 7, 8, and 9 that are powered by the four- cylinder engine. The two-blade prop with its aluminum hub and available precut, balanced spinner weighs about 20 pounds, considerably lighter than similar-sized metal props and rivaling the weight of wood. The blades come in any combination of red, white, gray, yellow, or classic black, and it can be indexed without special tools, using the pitch gage system so well accepted on the Sensenich O-320 and three-blade Rotax props. "This O-360 prop gives the builders of Van's and other high-performance designs, including the Wittman Tailwind, Mustang II, or Thorp designs, a versatile prop for the O-360," said Don Rowell, Sensenich president. "This new prop, along with our O-320 propeller, carries no rpm range restrictions to allow optimum cruising." The 72-inch-diameter O-360 prop is suited for airplanes that regularly travel in the 150- to 215-mph range, and it has demonstrated speed increases of 5 to 10 mph over the full range of practical throttle settings, along with improved throttle response and acceleration in real-world fl ying tests against existing-design propellers from other manufacturers.

Sensenich Introduces O-360 Composite Adjustable Prop IMMEDIATELY FOLLOWING EAA AirVenture Oshkosh 2014, Rainbow Aviation of Corning, California, will conduct a two-day (16-hour) LSA repairman inspection course for EAA members in Oshkosh, Wisconsin. Successful completion of the course allows an aircraft owner to perform the condition inspection on any experimental light-sport aircraft (E-LSA) he owns. People who successfully complete the course will need to present their certifi cate of comple- tion to their local fl ight standards district of ce to receive their FAA certifi cation. Some of the reasons to enroll in Rainbow Aviation's Repairman Inspection Course: • Learn critical information on today's experimental aircraft and engines. • Find out more than 100 mistakes that cause engine failures. • Gain valuable information about the main- tenance and inspection of your aircraft. • Learn the common mistakes on ama- teur-built aircraft that can af ect your liability and accountability. Many participants in previous classes report correcting major problems on their aircraft as a direct result of the information learned in class. More than 80 percent of participants learn about problems on their own aircraft of which they were unaware. Left unad- dressed, these problems would have led to engine failure. The certifi cate earned is valid for any E-LSA currently owned or purchased in the future. The course fee is $375 and is for EAA members only. To register, send an e-mail to info@rainbowaviation.com or call Rainbow Aviation at 530-824-0644. For more infor- mation, visit www.RainbowAviation.com . Repairman (LSA) Inspection Course Slated at Oshkosh After AirVenture MAX AERO INC. of Hartford, Wisconsin, is now of ering kits for builders of the Wittman Model 10. Max Aero owner Marc Stamsta has been building airplanes and airplanes kits for more than 32 years, including wing kits for the Pitts Model 12 and Tailwind Model 10 as well as wings for the Howard, Fairchild, and Waco antique/classic aircraft. Working with Tailwind guru Jim Clement to include some of his modifi cations to the Wittman design, Stamsta has de- veloped wing kits ($3,500), assembled wings ($8,500), engine cowling kits ($830), fuel tank kits ($800), a tail surfaces kit and a fuselage kit that will be available in limited quantities this spring.
