After taking on a bet it couldn’t be done while drinking beers with his buddies, Jack Bally started building a flyable, 1/3 scale B-17 Flying Fortress.
The one-third scale model B-17 was displayed at AirVenture, and is certified by the FAA in the Experimental category.
Named Obsession, but best known as the Bally Bomber, it took 17 years and 40,000 man-hours to get into the air and eventually to Oshkosh in 2018. Thousands of EAA members followed its progress for years.
“The Bally Bomber embodies the spirit of homebuilt innovation and creativity,” said Rick Larsen, EAA’s vice president of communities and member programs.
Richard Kosi, is the Bally Bomber’s test pilot and made nearly 60 visits over 13 years to Jack’s build as an EAA technical counselor.
A scaled-down B-17 Flying Fortress is a unique attention-grabber, and Richard pointed out that any homebuilt with four engines is pretty rare in its own right, saying further that flying the Bally Bomber isn’t the easiest thing to do.
“This is just a lot of fun,” Richard said. “It’s a challenge, a big challenge. It’s underpowered a little bit but it flies. It’s between fair and good on flight characteristics. But what do you expect, it is what it is.”
The aircraft is powered by four Hirth F30S, 4-cylinder engines producing 60 horsepower each turning GSC Systems custom wood propellers with metal hubs.
