Undaunted Airshows uses the most popular kit plane, the Van’s Aircraft series of sport planes. How popular? Van’s Aircraft was founded in 1970, meanwhile a little ways north, the first Boeing 737 was delivered in 1968. The 737 was, until recently, the most successful single aisle aircraft hitting a build rate of 60/month in 2019. As of this writing, there have been 11,154 Boeing 737s delivered compared to the Vansaircraft tachometer showing 11,158 First Flights.
Special attention was paid to the aerodynamic aspects of the cooling system, canopy system, weight, and the wing rivets are filled in. Other than that, just careful rigging and attention to detail make this airplane a fast cruiser even when not sucking down 80lbs of nitrous in a 10 minute race. This RV is spectacularly fast on nitrous able to achieve 300mph in level flight at 5500′ DA, but will hold 227mph (just under the published VNE of 230mph) true between 4,000′-9000′ naturally-aspirated with a fuel economy of nearly 30mpg!
