Actually, there is a tube on the front part, within the spring, but
black carbon tube does not show too well.

Looking at Treger's drawing (in INAV 125) I find that he uses 0.35mm
(0.0138") wire for the axis. Mine is 0.30 (0.0118"), as that size is
readily available, but maybe that is too thin and bends in an
uncontrolled manner? What size are other D fliers using?
