Ivanov Aero seems to have been founded about 2008 and gone out of business in 2016. The design is apparently out of production.[3]
The ZJ-Viera was designed to comply with the European single seat deregulated rules and US FAR 103 Ultralight Vehicles rules, with an empty weight of just 770NaN0. It features a cantilever low-wing, a single-seat open cockpit with a windshield, fixed monowheel landing gear with wingtip wheels, or optionally tricycle landing gear, and a single engine in tractor configuration, mounted on a short nose pylon.[1]
The aircraft is made from composite materials. Its 7.51NaN1 span wing has an area of 9.1m2 and the design has a swept cruciform tail. The standard engine used is the 260NaN0 Hirth F-33 two-stroke powerplant, although a 220NaN0 engine can be used.[1] [4]
Before the company went out of business in late 2013, InterPlane Aircraft acted as distributor for the design, touting it for the US FAR 103 Ultralight category and the light-sport aircraft category.[2]
As of February 2017, the design does not appear on the Federal Aviation Administration's list of approved special light-sport aircraft.[5]
Reviewer Marino Boric described the design in a 2015 review as "the dream of ultralighting returns, but with a 21st century feel! Ultralight on the wallet, too, thanks to a combination of simple design and modern all-composite construction...this airplane shows every sign of becoming a landmark design".[1]
