Design and development
The Viper was designed for the Canadian advanced ultralight category. It features a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed conventional landing gear and a single engine in tractor configuration.{{cite web|url = http://www.tc.gc.ca/eng/civilaviation/standards/general-ccarcs-advancedullist-2036.htm|title = Listing of Models Eligible to be Registered as Advanced Ultra-Light Aeroplanes (AULA)|accessdate = 25 January 2014|last = Transport Canada|date = 30 December 2013}}
The aircraft airframe is made from wood, covered in doped aircraft fabric. Its {{convert|27.00|ft|m|1|abbr=on}} span wing has a wing area of {{convert|102.0|sqft|m2|abbr=on}}. The acceptable power range is {{convert|65|to|110|hp|kW|0|abbr=on}} and the standard engine used is a {{convert|100|hp|kW|0|abbr=on}} Suzuki automotive conversion powerplant.
The Viper has a typical empty weight of {{convert|585|lb|kg|abbr=on}} and a gross weight of {{convert|1050|lb|kg|abbr=on}}, giving a useful load of {{convert|465|lb|kg|abbr=on}}. With full fuel of {{convert|17|u.s.gal}} the payload for the pilot, passenger and baggage is {{convert|363|lb|kg|abbr=on}}.
The standard day, sea level, no wind, take off with a {{convert|100|hp|kW|0|abbr=on}} engine is {{convert|300|ft|m|0|abbr=on}} and the landing roll is {{convert|400|ft|m|0|abbr=on}}.
The manufacturer estimated the construction time from the supplied kit as 500 hours.
Operational history
By 1998 the company reported that one kit had been sold, was completed and flying.
In January 2014 one example was registered with Transport Canada.{{cite web|url = http://wwwapps2.tc.gc.ca/Saf-Sec-Sur/2/ccarcs/aspscripts/en/quicksearch.asp|title = Canadian Civil Aircraft Register|accessdate = 25 January 2014|last = Transport Canada|date = 25 January 2014|url-status = dead|archiveurl = https://web.archive.org/web/20110718042755/http://wwwapps2.tc.gc.ca/Saf-Sec-Sur/2/ccarcs/aspscripts/en/quicksearch.asp|archivedate = 18 July 2011}}
