Brucey, I think Aerohead has a good point. Don't give up on this yet. Before you change anything do a tuft test to see if you have attached flow. (Look at Craig Vetter's site for good photos of tuft testing) If you find your angles are too steep, as the template may suggest, is there a way to tilt the whole thing upward and then extend the bottom if necessary? In post #47 the CRX only has a top and sides. The airflow under the bottom is less clean and may not be worth going after. Some experts state the maximum angle for the bottom cannot exceed 4 degrees. This is simply not practical for the real world. Good luck.
