definatly four bladers and contrarotating ! i made a 1/12th scale one some years ago , think i got my props from propshop in polished brass to the correct scale size , it used to give a very good turn of speed ! unfortunatly although it ran on 12 volts i cant remember what motors i used sorry . if anybody knows of the boat its 47-018 max aitken111. bembridge iow . it was sold onto a member of portishead model boat club , from whom ive lost touch !
