The Yak-110 is a twin-engine, single-seat aerobatic aircraft. It was designed in the late 1970s by Yakovlev Design Bureau for competition in the World Aerobatics Championships.

The Yak-110 is a Russian single-engine aircraft designed by Yakovlev. It was the first fighter plane to be made in the Soviet Union since World War II.

From the 1915 Blackburn TB double-floatplane Zeppelin attacker through today’s White Knight Two and Stratolauncher spacecraft carriers, aviation history is replete with instances of siamesed, twin-fuselage aircraft. It was a simple method to double horsepower without having to build a whole new twin in the early years. It later became a handy way to increase personnel, fuel, or cargo capacity. The North American F-82 Twin Mustang was the most successful, but the Heinkel He-111Z—a five-engine, two-fuselage kludge designed to tow the obese Messerschmitt Me-321 troop-carrying glider during World War II—had its day in the sun as well.

A free-thinking group of airshow pilots recently added a daring new mirror-image mutant to their ranks when they merged two Yakovlev Yak-55 radial-engine, single-seat acrobatic aircraft to produce what has unavoidably been dubbed a “Yak-110.” It required a meticulously designed and manufactured center section connecting the two fuselages, as well as horizontal stabilizer mating and outboard horizontal tail trimming. Both cockpits are operable, and the Yak-110 has been thoroughly tested, including a complete range of standard aerobatic performances.

Dell Coller of Dell Aero Speed in Caldwell, Idaho, is now installing a 3,000-pound-thrust GE CJ610 turbojet slung under the center portion to the aircraft. The engine, which is essentially a Lear 25, will produce nearly four times the horsepower that the Yak-110’s two nine-cylinder, 360-hp Vedeneyev radials currently produce.

Jim Franklin, who started flying his Jet Waco UPF-7 in 1996, was the first airshow performer to pair a CJ610 with a piston engine. In 2005, that aircraft, along with Franklin, were lost in mid-flight during an airshow. Coller’s Screamin’ Sasquatch Jet Waco, a 1929 Taperwing with a CJ610, debuted in 2014 and has since been a popular attraction at airshows. 

The Yak-110 was recently on display at the EAA AirVenture in Oshkosh, Wisconsin. It, like the F-15, F-16, and a number of other superfighters, has a thrust-to-weight ratio higher than one-to-one, allowing for some unusual aerobatics.



The Yak-110 is a combat aircraft used by the Soviet Union during World War II. It was designed to replace the Yak-3 and Yak-9 fighters, but only saw limited use. Reference: yak-110 top speed.
