Hi, Mike - you may have heard about or seen a picture of this model.
It was built by John Brodak and is a masterpiece.
It did not participate at the Fly-In.
Powered by a five cylinder radial engine, he did an amazing job of scratchbuilding many of the components, like the machine gun.
When I was testing the engine, it turned out that it was assembled at the factory but the cam timing was out.
I had to disassemble it and analyze the cam drive and valve train to figure out and set the timing. There are NO TIMING MARKS!!
