Just finished working on Big Boy , scooter number two , had to modifying the battery tray and hold down . I think it goes five hundred feet a minute , that is what Karim said reviewing the video , wow now ready to fly ! I have not been in the water with it for eight years or so but trust it having a bullet proof design . Look Ma Ma I have no fins with a tank or two on my back and you mutton heads soon will see . Not in a box but a circle is what I had in mind ! Goodtimes Rumdumb
