37MM and 32MM Blade Grip Arm
Your M7 comes with two sizes of
blade grip arms for you to customize
your M7's rotor geometry.

The axial bearing cage's open side must face outward towards
the rotor blade to prevent premature axial bearing failure.
Your M7 comes with six washers
Φ10xΦ12x0.1. These can be installed
symmetrically between blade grip and
blade grip spacer to increase damping
hardness. Not for use with POM
dampers!

Your M7 comes with optional
POM dampers for extremely hard
response. POM dampers are made
for high headspeeds and may
cause adverse effects at medium
to lower RPM, such as excessive
control cross coupling, wobbling
and in-flight resonance. Do not fly
below 1100RPM with POM
dampers installed. POM dampers
are to be installed as shown. Do
not use Blade Grip Spacer 7-078!

The spindle shaft pivot must be
removed for use with POM dampers.
