I have an OS MAX 28F engine that came out of a Hirobo Shuttle heli that I'd like to use on a plane. I know that they made this model engine in an "airplane" configuration (ie a horizontal muffler vs the heli's verticle muffler). The thing is I don't have a prop for it because it was a heli engine.

I can bolt it down to a stable platform, but I don't really know how to "turn over" an engine that doesn't have a prop... Can this even be done? I'm not going to run it for long (less than a minute or 2 just to see if it still works; it was discontinued in 1982....)

What do I need to do in terms of priming it and starting the engine? I don't want to waste money on an engine that doesn't work, but I really don't know how to test it out.

Does anyone have any ideas?
