got this engine long back and flew it in a few century hawk pros. I never could get it as reliable as the OS 32 so I took it out and it had been sitting for about 5 or 6 years now. Engine was oiled when I put it up for storage and is not locked. Engine ran when I took it out of my last heli.
Engine does have a few mark inside the casing, as seen in the picture, from when I tried installing the clutch without a crank holding tool. Engine still ran with those marks.
Muffler had normal wear as seen in pictures.
You will need two carb screws, glow plug, throttle arm, and exhaust bolts.
I am thinking about $60 shipped only US, Paypal as purchase not friend.
