Remote control hovercraft (Caversham RG4)

A tyco hovercraft.... Had this since I was a kid! It needs a new battery, the controller has the wrong aerial.... I put a random one on it when I broke it as a kid. I tested it about a year ago and it did work, unfortunately though the skirt has tares in it though now. If you have the patience that can be fixed though, which is why I'm putting it on here as if it doesn't get fixed soon it'll just get worse and I doubt I'll get round to it!
