Unknown Heli ID help

This helicopter has been in our collection since before 1998. It is 47 1/2″ long and has a 55″ rotor diameter. That’s all we know about it. Who donated it? Where did it came from? What type of helicopter is it? Did it compete in anything? Win anything? The answers to these questions are a mystery that we’ve been trying to solve for the last six years.

We’ve gotten a lot of great help and insights from AMA members already, and some progress in ID’ing it has been made. There’s a thought that it is Russian in origin, due to the Pruss-designed rotor grips and the engine.

To learn more about the work that has been done to ID this model, watch the Fly By!
