Andy, While I am on the subject, I recently performed some "plastic magic" on a "USS New Jersey" kids toy battleship from theArgos catalogue shop, costing a mere £14.99, (and its a corker of a model, once painted up a bit ; the detail is quite stunning for a kids plaything and its a respectable 26"in length) and used a lightweight 2mm shaft and 30mm with a Como 280 motor on 4.8v…the performance was…er, ok.. so i fitted a Graupner speed 280 instead on 6v and the thing really flies now….wish the bow was a bit more pointy, it might get up on the plane!. So..motors,, you never can tell. Ashley
