CS-Hover thanks for posting the link to the 429 PDF file but that has to be one of the poorest documents I have ever seen produced by any company, let alone one of Bell's experience and reputation.
Where are the interior dimensions and layout config diagrams, the top level performance info or indeed any information that might give us some idea of the capabilities of the aircraft.
It also refers to the Aircraft Technical Manual at the end so perhaps someone would be kind enough to post a link to this!!!
