XS Aileron Hinges

[Michael Gamble <mp.gamble@virgin.net>]

  I believe there have been cases of cracking of the glass  around the
hinges.It has been suggested that I fit an extra aileron hinge outboard of
the inner balance weight and add extra plies of uni at the hinge positions
on wing and aileron.  Factory believes these mods are unnecessary. Any
comments?
