What's the consensus on using GPU cranks in aircraft engines? I found a fresh engine that looked great until I found out that it has a GPU crank installed. This is unfamiliar territory for me.
From what I understand the GPU crank is the same as a 0-200 crank but it has 2 extra holes in the prop flange and the center boss is shorter than the aircraft crank. The prop studs are smaller in the flange and have bushings on them on the prop side to fit the std1 aircraft prop and bolts.
