I saw in the site http://www.helis.com/timeline/aerospatiale2.php that the
gazelle was the first helicopter with fenestron and also incorporated a
rigid
main rotor as the BO105's,

I never saw a gazelle so close how for to detail its main rotor,
is this true?, the gazelle has a rigid main rotor similar to the BO105's.

No it's "semi-rigid" and was developed with Bolkow. In fact it has more in
common with the Allouette II than the 105.
