4.1 Propeller mounting
Be sure to possess a suitable and guaranteed propeller by Vittorazi for your motor.
Attention: the propeller can be mounted in two opposite position in comparison to the
reduction drive, which only one is correct. Ask to the authorized dealer or to the
instructor, if you are not certain for the assemblage of the propeller.
Model Easy100: rotation propeller clockwise, considering the back view
(same view of the picture 4.1).
Model Fly100evo: rotation propeller counterclockwise, considering the back view.
Push the propeller against the reduction drive, untill to insert it completely. Now gently
screw the bolts up to the end. Be sure that the bolt are proper for the propeller,
therefore the threads of the bolts are inserted at least 10mm in the hub. Now to tighten
the bolts of the propeller trying to get the same pressure on every point, picture 4.1.
Not do exaggerate with the pressure on the bolts, there is a risk to crush the propeller, if
in wood.
Have a maximum pressure of 4 -5 Nm, if the propeller is in composite carbon.
Propeller in wood: once tightened the propeller, it is opportune to check that the pich of
the two blades is identical. If there is a considerable variation among the two blades,
this difference can be compensated through the pressure of the bolts.
If you don’t know this method of balancing, ask to an authorized instructor or dealer.
Check the tightening of the wood propeller every 3 hours of flight and repeat the
balancing.

In the case of a broken propeller, we invite you to purchase from a Vittorazi dealer, the
same propeller for measure and profile, guaranteed from the factory.
