12/29/2014. Remarks by Walter van Tilborg and Johan Visschedijk: "The WA-200 Vision light aircraft design was developed from the WA-100 Spirit, also a design of Max Tadesco from Colombia and was marketed in the USA by WAC (World Aircraft Company, founded by Canadian Eric Giles). The type was available as ready-to-fly aircraft (S-LSA) and as kit to comply with the E-LSA (Experimental-Light Sport Aircraft) or E-AB (Experimental-Amateur Built) categories and was first presented in the USA at the 2012 Sun 'n Fun EAA convention. The all-metal Vision was stressed for +6 and -3G and offered STOL performance and had a large wind shield and large transparent doors for enhanced visibility.

Vision: The original version which featured a Garmin radio suite.
Vision Sport Edition: This lower cost variant featured analogue instruments and was introduced in December 2013 as the Vision LT, in December 2013 it was renamed Vision Sport Edition.
Vision Grand Edition: Introduced simultaneously (July 2013) with the Sport Edition and featuring a Dynon avionics/radio suite, an autopilot and dual radios. Engine was the 100 hp Rotax 912ULS2 as used in the initial Vision and Sport Edition models.
Sentinel: This name was used for a law enforcement variant of the Vision. The Sentinel was equipped with the light-weight Mosquito aerial observation system which was carried inside the fuselage. The system included a camera, GPS, computer and could be operated at altitudes between 50ft and 18,000ft. Usually the Sentinel also featured large transparent panels in the lower cabin doors.

Although the first two Vision aircraft, N68SN and N64SN, are presently registered by the FAA register as Sentinel aircraft, they are in fact Vision Sport models."
