Peter, You can have them mate(no cost), as i said, I won't use them. Just the postage from Australia, sent surface mail, as it will take u a while to build the ship...Dont have them with me currently I am at work but when i get home will see if I can find any specs relating to them - they are just the small electric motors similar to what you would probably find in a scalextric slot car, but they do have all the battery wires to make u life a bit easier, may need to look into gearing them... As Jon states above u will have to work out how u are going to "dodgy" up some sort of a rudder and shafts....
regards.
