Yak 54 32 Percent
The Yakovlev Yak-54 — Russia's two-seat unlimited-aerobatic answer to the Sukhoi monoplanes — rendered as a one-third-scale gas-powered giant.
About
The Yakovlev Yak-54 is the work of the Yakovlev design bureau, the famed Soviet OKB whose aerobatic lineage stretches back to the UT-2 trainers of 1937 and includes the Yak-50, Yak-52, and Yak-55 series. Designed by Chief Constructor Dmitry Drach and Lead Engineer Vladimir Popov as a development of the single-seat Yak-55M, the Yak-54 was announced in 1992 and made its first flight on December 23, 1993, with the prototype shown at the Paris Air Show that same year.
The Yak-54 is a two-seat sport-aerobatic monoplane — the rear seat lets the type double as an unlimited-aerobatic trainer, an unusual combination at the top end of the discipline where most competition airframes are single-seat. Production was carried out at the Saratov Aviation Plant from 1995, with capacity of more than a hundred airframes per year, before transferring to the Arsenyev Aviation Company "Progress" facility in 2005. The type remained competitive on the world unlimited-aerobatic stage through the 1990s and 2000s.
The Yak-54 silhouette is one of the most-modeled subjects in RC aerobatic flying. The unmistakable Russian-aerobat shape — pugnacious, short-coupled, with the classic Yakovlev flat-bottomed cowling — appears in foam and balsa kits across the modern RC market. The "32 Percent" in this model name refers to a popular giant-scale category for unlimited-aerobatic competition flyers; at this size the airframe carries a wingspan around 90 inches and a substantial gas engine.
In the simulator
The Yak-54 32% has the heavyweight character of a serious giant-scale competition mount. Substantial inertia, big oversize control surfaces, and the kind of presence at altitude that makes 3D figures read clearly to an audience. Use it for the unlimited-aerobatic vocabulary: knife-edge spirals, slow rolling circles, hovering on the prop, and the classic Russian-style snap roll. Pairs well with open landscapes that give a giant-scale model room to breathe. A different character from the Edge 540 33 Percent in this same pack — same competition class, but with Yakovlev's distinct Russian flying personality versus Zivko's American direct-action design.
