Very nice! I have one squirreled away. I need to improve my skills before I tackle it. What was the challenge with the injected molded parts? Fit? Filling? Finishing?
I never liked the look of the duck foot fins, I retrofitted mine with clear triangular polycarbonate fins, slotted the side and main tube and glued them in place with a flexible clear CA, nearly invisible, don't break off, are moderately sized didn't have to add any nose weight, flies great.
