FIRST PARAGRAPHS OF BUILD ARTICLE:
"The first A/1 glider in this series had a wing similar to AmI but had a balsa "box" fuselage and "T" tail. After one or two instances of tail flutter this was altered to a semi-high tail with dihedral...a layout which the designer still thinks has advantages for 'still' air. However this arrangement gave poor towing characteristics although the glide was good, in fact, the model was eventually lost.
The second model was experimental having a glassfibre pod with alloy tube boom - the wing had a sunken 'box' spar. Again a good glide performance resulted but the use of a constant diameter tube caused the weight to be in the region of 7 or 8 oz. This model was broken before it was fully trimmed.
Soon after, the present wing was started, the sunken spars being retained to try and maintain a laminar flow over the upper surface of the wing, and to avoid sudden changes in curvature usually present due to surface spars and tissue sag, which may cause early break-away of airflow..."
