Thanks Chris I can now put a name to it, this was also the first model that I purchase (EBay) It was a bare hull and unfortunately in my exuberance I over did it a bit by fitting 3 x 5 bladed props and obviously 3 motors, you can imagine the fright I got when I first put it into the lake, off it went at about light speed, I was lucky to get it back. Had to remove the centre motor, shaft and prop. It still has all its radio gear but too afraid to retry in the lake, so just an ornament now.
