Back to the Go3:
You remember my remark on the stiffness of the rear swing arm?
The swing arm is NOT carbon fibre as many people believe. It is glass fibre. I gave it experimental stiffening rods made from wood - spruce, lightweight and comparatively stiff:
Fitted into the arms of the swingarm and glued with elastic PU glue (Sicaflex 201)
This noticeably reduces movement toward the side, but of course has almost no effect on torsion of the arms (which i understimated). Which leads me to the conlusion that i will need to replace them by carbon fibre bodies filling the full height of the swing arms as well. Not in winter, and i need to learn to work with carbon fibre.
