Hi. I just won an auction for a nikko sea star. I have no idea how old it is. The owner said the prop is missing and the dive/surface feature does not work. Otherwise the sub is in good condition. I need some info on a replacement prop and trouble shooting the dive/surface function. Can anyone help me? Mabey there is a web site I can go to? I also have two walmart subs that i'm presently modifying. I have made a career working on the real subs for the navy and am presently workin on trident missle subs. Thanks, Ron[8D]
