I would urge caution on anyone thinking of removing material from the mono
swingarm to lighten it. I was up at Kirkbymoorside some years ago when Roger
Bull was asked about this, and he pointed out that the swing arm is a
component that can be very heavily loaded, especially in a crosswind
landing, and he did not recommend putting any lightening holes in it.
Any UK owner would be well advised to consult the LAA before taking any such
action, as this would definitely require modification action and not be
permitted simply with the approval of the local inspector.

on the subject of weight savings, I can't help but notice how heavy the mono
swingarm is. I noticed in Germany one builder had put many lightening holes
in it (among many other mods). I had also wondered if indeed it was
over-designed and could use some strategically placed holes. Is that the
only builder who has lightened it? Has anyone done any math on that heavy
piece?
