The VSR SR-1 Snoshoo ({{langx|en|Snowshoe}}) is an American homebuilt Formula One racing aircraft that was designed by Alan VanMeter and A.J. Smith and produced by VanMeter Smith Racing (VSR) of Wichita, Kansas. It was designed in 1993 and first flown in 1997. The aircraft is supplied in the form of plans for amateur construction, with some key parts available to speed construction.Purdy, Don: AeroCrafter - Homebuilt Aircraft Sourcebook, Fifth Edition, page 280.

Design and development

The SR-1 Snoshoo features a cantilever mid-wing, a single-seat enclosed cockpit under a bubble canopy, fixed conventional landing gear with wheel pants and a single engine in tractor configuration.

The aircraft fuselage is made from welded 4130 steel tubing covered in carbon-fiber-reinforced polymer fairings ahead of the wing and doped aircraft fabric aft. Its {{convert|19.91|ft|m|1|abbr=on}} span wing is made from Sitka spruce wood, has no flaps and has a wing area of {{convert|66.00|sqft|m2|abbr=on}}. The cockpit width is {{convert|22|in|cm|abbr=on}}. The acceptable power range is {{convert|95|to|100|hp|kW|0|abbr=on}} and the standard engine used is the {{convert|100|hp|kW|0|abbr=on}} Continental O-200A powerplant, as required by the Formula One rules. The aircraft is stressed to +/-8 g{{Cite web|url = http://snoshoo.com/|title = SR-1 Snoshoo |accessdate = 26 March 2014|last = VanMeter Smith Racing |year = 2014}}

The SR-1 Snoshoo has a typical empty weight of {{convert|530|lb|kg|abbr=on}} and a gross weight of {{convert|760|lb|kg|abbr=on}}, giving a useful load of {{convert|230|lb|kg|abbr=on}}. With full fuel of {{convert|6|u.s.gal}} the payload for the pilot and baggage is {{convert|200|lb|kg|abbr=on}}.

The designers estimate the construction time from the supplied plans as 1500 hours.

Operational history

By 1998 the company reported that 20 kits and sets of plans had been sold.

In March 2014 one example was registered in the United States with the Federal Aviation Administration.{{cite web|url = http://registry.faa.gov/aircraftinquiry/AcftRef_Results.aspx?Mfrtxt=&Modeltxt=SR-1&PageNo=1|title = Make / Model Inquiry Results|accessdate = 26 March 2014|last = Federal Aviation Administration|date = 26 March 2014}}
