It still runs, though.

My H74 needed to have the pump ‘belt’ twisted 180*.  Its fan blows out through the radiator instead of pulling air into it, but it still happily runs through each tank of gas with the pleasant exhaust note of a twin.

These are ‘model’ engines.  They are toys for gearhead hobbyists.  They are intended for display, tinkering, and occasional running.  The price point and o-rings on the pistons make that obvious.  If you guys are expecting a continuous duty cycle with B-10 engine life, then you are shopping in the wrong store.

As mentioned before, anyone who has actually made a running miniature engine (or tried to) will understand what an incredible value Jin’s engines are.
