The guy has built this from scaling down 1936 American plans. Its powered by a 4hp motor with a centrifical clutch. Its taken him a while to get the set up right and has a box full of different props and turn fins etc. He puts GPS in it and records the maximum speed, yesterday it went 73km/h.
Its transported around in the back of his 1949 Chev Ute thats pretty cool too.
Enjoy.
