30° from the vertical, an appropriate support (saddle) must be
installed.

• Use the ange to mark the centre of the holes on the tube.
• Fix the drilling template on the reference points, making
sure they are aligned with precision at the half-way point of
the tube.
N.B. All holes must be exactly aligned with the half-
way point of the tunnel, since tolerance between
propeller and tunnel is minimal.
• Take care that there are no resin residues in the contact
area between ange and tube; this could cause misalignment.
Any resin residues and any other hindrance to correct
contact must be removed with sandpaper.
