It's been around for quite a few years. Actually uses an Aussie made radial engine.

would love to see it go down the quarter mile to see how it performs.
Had a look at radial engines , like a Harley , the crank only has one pin that all the conrods attach . The motor in that bike spins up instantly , couple of youtube vids of it . Sounds Great !
