Did anyone manage to tape the programme on Sam Cody broadcast last
thursday (16/9/93) around lunchtime on BBC2. I would dearly like to borrow
a tape (and copy it).

BTW, what do people use for wing spars in medium-sized deltas? I have a
2.5m span Conyne delta with 6mm dowelling (8mm for the spreader) which
suffered a major trauma yesterday in 15-25mph+ gusting winds. It collapsed
spectacularly with all 3 spines and 2 wing spars breaking simultaneously.

I have now fitted 4mm fibreglass rod to the wing spars .

Paul (who now knows the upper limit of this one)

I measured the spars in one of my Dan Leigh deltas which is about that
size. He used 8mm dowel spars, 10mm dowel spreader.

I have an even larger Delta Conyne (4m span) made by Sun Oak which has 12mm
square *hardwood* spars. These have never broken though the kite has
sometimes crashed in a way that I would have expected to break spars made
of lesser material.

In my experience, fibreglass breaks much less readily but is capable of
doing much more damage to the kite when it does so.

I'd love to see it and copy it too, if that can be arranged. Maybe I can do some kind of a deal ...

I have used 6mm and 4mm in mine; for the size of yours I'd suggest 6mm.
