Pre-Flight Checks

Before every flight the following has to be controlled:
Check blades for security of mountings.
-
Blades cannot be turned by hand.
-
Check engine / Gearbox bearings for excessive play.
-
Blades are not damaged and have no cracks
-
Hub without cracks
-
Check bolts for tightness and security of wire locking.
-
Check clearance between propeller-blade tips and propeller guard.
-
Simply slight resin-flaking by debris can be accepted, but should be repaired
shortly. The repair can be done with economical application. If the check is not
satisfactorily the handling has to be stopped and the propeller repaired.
Warning:
A propeller failure has more serious consequences than an engine failure! Due
to damaged blades an unbalance can arise, which can cause the motor to be
torn out of its bracing, thereby changing the proportions of the centre of gravity
in such a way that a stable flight attitude cannot be maintained.

Maintenance

The propeller should be cleaned at the end of each days operation.
This prevents the built up of dried grass and insects etc. on the blades. Cleaning
of the blades should be carried out with a soft sponge using a weak detergent
solution.
Annually, the propeller should be polished professionally. It is recommended that
this is carried out by a respected coachbuilder or similar facility.

Warranty

HELIX Carbon GmbH warrants the Propeller for two years from the date of
purchase (according to German law). The warranty covers material defects but
does not cover subsequent losses.
The operator flying with this Propeller does so at his/her own risk.
