excellent working model. had to true up crankshaft by eye using pliers to stop flywheel running out of true. I’m a very happy man.
put it on a cup of water, waited a minute, flipped the fly-wheel, and away it went for nearly half an hour. Fun little desktop item for the guy who has everything. Well packed so would feel comfortable shipping it as a gift.
They look and feel awesome but have not tried
my father loves it.
