Experience aviation history like never before with The Ultimate Radial Aircraft Engine, a working 44cm tall replica built from over 3000 pieces.
This massive model is powered by a medium electric motor and battery box, driving the crankshaft, rotating pistons, and 2-blade propeller in smooth, realistic motion. Every component has been faithfully recreated, from the chrome accents and modeled exhaust manifold to the authentic structural design that defined early aviation.
Mounted on a sturdy display stand, this engine is more than just a model — it’s a functional tribute to the machines that ruled the skies. With its sheer piece count and mechanical realism, it stands as one of the most advanced and rewarding aircraft engine builds ever developed.
Bring the roar of flight engineering into your hands.
