(yes, its probably fake and running from air, but still)

Seen that one before. As it's running from compressed air, then it can't be a true 4 stroke internal combustion engine can it?

Still some nice precision engineering that any model maker would be proud of.

EDIT it's not 4 stroke, the camshafts are geared 1:1 to the crankshaft.

cant see any way it could be a 4 stroke, so must be on compressed air. but still, a lot of work has gone into it
