This is one of Howard Hughes' racers from the '30s. The errors are cumulative, so I probably won't continue working on this one. I'll just haul it out behind the garage where it will be out of sight.
One thing I've discovered from this first aircraft model is the importance of having a good plan to work from. I only had a small .gif 3-view for the Hughes plane, so it was difficult to render forms with any precision. I have a much better plan for a similar racer from the same era now, so we'll see how that goes.
