Greetings all,
I recently obtained this gas engine that came off of an RPV (Remotely Piloted Vehicle)
It is in beautiful shape and was never really run as the RPV never flew.
Only trouble is, I have no idea what this engine is. The most unique thing is that it has the crankshaft extending out both ends. I think it must be about 40cc in displacement.

I have posted several pictures at the following location and would sure appreciate somebody taking a look and maybe letting me know what I have here.

Thank you all in advance for your time and effort.
