Amazing Rotomotor 4 Cylinder 4 Stroke RC Airplane Engine

Here is an amazing 4 cylinder opposed 4 stroke RC airplane engine from the Czech Republic Rotomotor. What a real beauty and not cheap either. I think it was around $2500 but Wow. It shipped in a custom made wooden case. The displacement is 170 cc which is the size of a motorcycle engine. Very nice workmanship indeed.
