Radikal N640
The flybarless head comes pre-assembled
however, it is only assembled as an ex-
ample of how it should be assembled. The
entire head will need to be taken apart and
medium thread lock is required on all metal
to metal parts. Ensure lubricant is applied
to the thrust bearings. Be careful when
taking the thrust bearings out of the blade
grips. The radial bearings (part #9) should
stay within the grips. DO NOT try to remove
these as they have been factory installed.
It is best to remove the grips one side at a
time. Before assembly, notice the direction
of the control arm on the grip. It should be
assembled as indicated within this diagram.
