This time Dave Goodenough adds to his diesel collection, looks at control surfaces on wings and witnesses a Spruce Goose take to the air. As mentioned in a previous ‘One Man…’, I had suggested following up on a theme I’d been asked about earlier: converting existing model kits from rubber power to electric powered R/C devices. It’s been done before by many, from the small, scale kits supplied by several companies, up to models approaching a one metre wingspan. So where to start?
