MAINTENANCE ITEMS
PROPELLERS
Propeller blades should be removed when making a change to the configuration of
the ALTA 8 to prevent propeller strikes in the event of unintentional motor starts and
should be replaced on an as needed basis if they become damaged. Generally, a nick
on the leading edge that is large enough to catch a fingernail indicates that the pro-
peller should be replaced. If the blade composite structure becomes delaminated,
the propeller should be replaced.
Freefly makes folding propeller assemblies available that include the blades and
propeller hub fully assembled and factory balanced. They are available in clockwise
and counterclockwise orientations.
CAUTION
Only use propellers supplied by Freefly on ALTA 8. Use of third-party
propellers can cause motor instability, overheating, and failure.
