The CH 300 is an enlarged three-seat derivative of the Zenair Zenith CH 200, designed by Chris Heintz in the mid 1970s as the Tri-Zénith.Taylor 1976, p.458. Like the CH 200, it is a low-winged monoplane of all-metal construction with a fixed nosewheel undercarriage, but is larger and more powerful, and is fitted with a rear bench seat capable of accommodating a third adult or two children, and is fitted with a forward sliding canopy. It is designed to be powered by an engine giving between 125 and 180 hp (93 and 134 kW).Zenair, Zenair pamphlet, circa 1986.
The first example made its maiden flight on 9 July 1977, with over 400 sets of plans sold by 1982. One CH 300, modified with extra fuel tanks and piloted by Robin "Red" Morris, made a non-stop trans-Canada flight between Vancouver International Airport and Halifax International Airport on 1–2 July 1978, covering the 2,759 mile (4,440 km) in 22 hours, 44 mins, setting three FAI Class C-1c point-to-point speed records."[http://records.fai.org/general_aviation/aircraft.asp?id=3885 List of records established by the 'Zenair Tri-Z']{{dead link|date=July 2016 |bot=InternetArchiveBot |fix-attempted=yes }}".
