4. NORMAL OPERATIONAL PROCEDURE
4.1 INTRODUCTION
Section 4. Contains check lists and procedures to be used for the normal operation.
Procedures for additional equipment are in Section 8.
4.2 ROTOR RIGGING
The aircraft are fitted with 8.4m (orange end caps) rotors or the 8.4m RotorSystem II with
red end caps
, or the 8.4m RotorSystem II TOPP variant with blue end caps
. They weigh
as much as
3
5
Kg, and can be awkward to handle. Ensure that you have help when
moving them around, especially when fitting them to the aircraft. Use a suitable hoist as
required.
NOTE! Rotors fitted to Calidus aircraft carry tip weights not present in the MT series! End
caps are orange, or if fitted with RotorSystem II then red
, or if fitted with RotorSystem II
TOPP variant then blue
. Standard MT-series rotors (grey or black caps) are not released
on Calidus!
Assembly of rotor (photographs are from the MT series, as the upper rotor head and rotor
attachment is identical):
The rotor blades, spacer extrusion and hub are provided with numbers to define the
installation direction. By matching these numbers, put the blades into the hub. Fit the 6
bolts (per blade) fitted with ‘thin’ 9mm washers through the hub and blade assembly from
the top, and fit an 8mm ‘thin’ washer and M8 nyloc on the lower surface. The bolts are a
close fit – and may need a light tap to push home. Raise or lower the blade with respect to
the hub to achieve this. DO NOT hammer them in! If required, the tracking may be
checked and adjusted by using a taut string between the rear outside corners of the blade
ends. Tap the blades in the hub bar such that the string passes directly over the centre of
the grease nipple in the centre block. When satisfactory, tighten all 12 nuts to 25Nm.
Normally no tracking adjustment is required.
With the orange end-caps the bolts are all the same length. With RotorsSystem II (red end
caps) there are 5 different bolt lengths as these vary to suit the scalloped hub-bars.
Ensure that they are fitted in the correct position, as shown below.
