Design and development
The Jora was designed by Oldrich Olsansky who also designed the similar
laminates, covered by polyester fabric. The main exception is the central fuselage section, which has a riveted tube frame.[1]
The Jora has separate wings with constant
flaperons), constructed like the wing, are attached to an auxiliary spar. Separate ailerons and flaps are an option, in which case the wing profile (airfoil) is changed from the laminar flow UA-2 to SL-1. The wings can be detached for transport, though wing folding is an option.[1]
Apart from its tube centre section the fuselage is wholly laminate with strengthening
disc brakes.[1]
The standard engine for the Jora is a 38.2 kW (52 hp)

By 2009 at least 161 Joras had been sold to customers in Australia, the Czech Republic, Denmark, Finland, France, Indonesia, Ireland, the Netherlands, Norway and South Africa.
