Hi Phil
I received a mono kit from Roger in late 2007 and I'm ashamed to say that I
haven't touched the torque tube yet to know if it is the heavier version you
describe - and I haven't seen a revised build manual or Mod 73 exemption
that would take it into account - please can you tell me when did you get
the new version from Roger, to give me a guide as to whether mine might be
the new version with my kit?
Thanks
regards
Richard
