As noted in the introduction, 'Dr Bob' is planning to use the same setup in the proposed Micro Hearns Brothers' 'Sportster', which he thinks he can probably get down to about a 13 inch span. He plans initially to make this as a 'stick and tissue' exact replica, but is also looking at making a Depron profile model as well.
