STRONGER 

The V9 mast uses the same extrusion die as its predecessor, the V5 mast, and adds a couple of strength upgrades:

The mast position is shifted backwards slightly to add more metal around the rear barrel nuts.

These barrel nuts sit deeper than in the V5, adding extra strength.

A 1.5 degree fuselage is now built in, lifting the nose of the board for an easier, more balanced trim while flying.
