Remarks: New reg for Croatia. Despite its similarity to the Sukhoi Su-29, the Interavia I-3 (also known in Russia as the Technoavia SP-91) is a different design, produced by the same man who produced the Sukhoi aerobatic series. This particular aircraft has been manufactured in 1993., and previously flew in the US. It is equipped with an EFIS cockpit (albeit with a single MFD) and a half-empty panel.
