Great runner!

I purchased this engine as part of an estate sale. I ran it on the test stand. It fired right up and runs great! It doesn't appear to have be run much, if at all. I would suggest breaking it in as per the manual.

According to an experienced, expert hobby shop owner, he says this engine screams with an 8X8 prop. 10X4 prop for sport flying.

The instruction manual for the O.S. 49-PI Type II (later model) is available on the Horizon Hobbies website:
