So I have OS 50 hyper that came apart and rebuilding it, But I see few problems I'm not sure is ok or needs to be replaced. The top of the head has little pitting from when the top of the piston came apart. And the crank I'm not sure if its good or not took few pictures.

She looks like she's been run hard and lean.
You could try some steel wool or wet sandpaper very light grit and or a green scotch pad to try to polish up the crank a bit and you could possiably reuse the head but it won't be as good as a new engine undamaged.

Oh No Someone Please Stop Me Before I Go Broke With This Heli Thing!!
