LSA America was at the U.S. Sport Aviation Expo with a new single place
ultralight design the ZJ-Viera. This lightweight all composite design is
available in both a tail dragger and tri gear landing configuration.
The ZJ-Viera is a true ultralight fitting under the Part 103 exemption,
and no license or medical is required to fly it.
Power is supplied by an F200, 2 stroke engine made by Flying Engines

The tri-gear version of the ZJ-Viera weighs in at a total empty

use of modern day composite materials, without sacrificing any strength

7 to 1.

people. This is aided by quick disconnects on the aileron control
The plane was designed and is being manufactured by InterPlane
manufacturers of the Skyboy series of lightsport aircraft. The planes
are built by InterPlane test flown at the factory and then shipped via
container to the U.S. where they are inventoried, reassembled and again
test flown prior to delivery to customers.
