RVE MERAK E750 - ASSEMBLY INSTRUCTIONS
SPINDLE SHAFT AND BLADE HOLDERS INSTALLATION (4-5, 4-7)
Install the dampers into the center hub using silicon grease. It allows an easier assembly but
also helps maintaining the damper’s flexibility and a good operation.
Clean properly the spindle shaft with isopropyl alcohol and install one of the M6 x 10 mm
screws with its washer using medium threadlocker. A one-way wrench can optionally be used
to tighten the first installed M6 x 10 mm screw.
The blade holder’s thrust bearings are pre-installed with thrust bearing grease.
Introduce the spindle shaft into the blade holder. Then a flanged washer should be installed
with the lower diameter side in contact with the blade holder’s bearing inner race. Then one or
more spindle shim washers should be used. Insert the spindle shaft with an installed blade
holder into the center hub and replicate the flanged washer/spindle shim washer setup
symmetrically. Insert the second blade holder and complete the assembly with the M5 screw
and its washer, taking care of using also medium threadlocker on it.
During the first assembly, install only one spindle shim washer on each side and complete the
rotor assembly. The blade holders should move freely but a certain pressure should be
guaranteed to just keep them in place. If the blade holders fall by their own weight or a little
play is observed, please add an additional spindle shim washer on each side.
It may happen that the initial spindle shim washer setup works well and after 20-30 flights a
little play appears. If this happens, add one additional spindle shim washer on each side.
