• If
not already installed tap the super cams until fully inserted and lock
them with the screw supplied.
•
Torque to 30 inch x lbs. Secure cam screw with red Loctite (#271), when
applying Loctite; apply it also on the square of torsional rod to protect
it from rust.
•
Torque on the mounting bolts: 200-inch x lbs.
• The
only time you need to lock the screw adjuster with lock nut is when you
pitch the prop between the neutral and two turns pitch decrease, in all
other pitch setting screw adjuster stays where you leave it without a jam
nut.
• It
takes 5.5 turns of the screw adjustor each way to go through full pitch
range.
•
Put safety wire through the hole in the screw adjuster to stop the jam nut
from falling off and in to the prop in case it would loosen up.
•
Use only the hardware supplied with the prop, never drill or modify the
bolt holes in the blades. Maintain the 200 inch x lbs. Torque on the
mounting bolts.
•
If you are not using super cams, screw the cam screw in the torsional rod
and secure it with red Loctite, to keep water from getting into the
torsional rod and putting the prop out of balance.
•
Make sure that there is at least 5" of clearance between the blade
tips and trailing edge of the wing, radiator, rudder or whatever because
the blades are designed to flex back and forth more than wooden blades.
• Do
not slide your fingers along the trailing or leading edge of the blade(s)
the fibers may piers your skin.
• If
you wish to increase top speed or decrease cruse RPM, switch to a 2-blade
prop or cut the 3-blade prop to smaller diameter using a hack saw. As long
as you cut the same length piece from each blade, the prop will remain in
balance.
•
Do not cut prop to less than 48" in diameter.
•
When switching from 3 to 2 blade configuration, increase the pitch about 4
degrees.
•
Rotax engines develop maximum horsepower around 6500 RPM. So pitch the
prop accordingly.
•
If you are going to use other than skull cap type spinner make sure that
there is at least 1/4" clearance between blades and cut outs in the
spinner.
•
If your aircraft holds U.S. experimental air worthiness certificate you are
supposed to contact the FAA FSDO before flying the aircraft, when notified
the FAA inspector can determine if procedure was a major change (As
defined per FAR 21.93 and listed in appendix a to a part 43) and if any
additional inspections or operating limitations are needed prior to the
flight.
