PROPELLER MOUNTING
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.
Modelo 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.
(fig. 3.1)
The motor that you are going to use is a two strokes engine. It requires for the lubrication
an established percentage of oil/gasoline. When at the gas pump, always choose gasoline
unleaded 95 octanes. The percentages will be pointed out in the following paragraphs, “break-
in” 4.5 and “normal operation” chapter 4.
3.2
FUEL
The gasoline is an extremely inflammable and explosive substance. When you
prepare or in every moment you are close to the fuel (gasoline and oil), not smoke,
not provoke sparks or flames. Never fill the tank of your aircraft when the motor is
running. Position the tank of the fuel before starting the motor at least 10 meters.
