I am impressed with the simplicity, practicality and weight saving. I have had a "collection" of the 1"sq tubing sitting there for the 'right moment'. The practical shape of the Disco has many advantages over the P38...but "we work with what we have".

I had thought of building the frame from said tubing and covering it with 3-ply to impart rigidity... the aluminium composite panel seems a better option.
Thank you for sharing!
