CG-4a Waco Update by Mike Horan

All the Waco team efforts during 2010 were concentrated on the wings. Julian has been working on a stub starboard wing about 0.6 metres (two feet) long which he will only be skinning on the upper surface. This will allow visitors to view into the underside and end to see the main and rear spar construction details. They will also be able to see how the end and first set of ribs are constructed and fitted.

Brian, Bob and myself have been working on the outer section of the port wing which is about 5 metres (17 feet) long. The spars were constructed during 2009 and then 2010 saw considerable progress on constructing and fitting ribs and applying about half of the plywood skin.

In late summer Ashley Letts joined the team and made a very competent start on constructing an aileron. This involves the most delicate work so far attempted as the ribs are built up using mainly 6mm square timber and even some of the stringers running the full 5 meters are only 6mm square (17 feet X 1/4").
