MAIN ROTOR BLADE ASSEMBLY

Blade Weight Installation
1.
Using 80-100 grit sandpaper, sand the blade
weight strip (2) to produce a roughened surface.
This will insure proper glue adhesion. Next, trim
the blade weight strips to equal lengths.
2.
Adjust the spanwise C.G. (center of gravity) of
the blades by setting the blade weight strip into the
blade slot and positioning them toward the front of
the slot (closest to the tip of the blade). Refer to
Section 8-4, Step 1 for clarification. Next, trim the
blade weights until proper C.G. is obtained. It is
suggested that the C.G. of the blades be matched
within 1/16" of an inch for proper balancing.
3.
Bond the blade weights to the blade slots by removing
the weights and filling the blade slot completely with
glue. We recommend either 6-minute epoxy of Pacer
Blade Zap for this procedure. With the blade slot filled
with the adhesive, submerge the blade weight to the
bottom of the blade slot and completely cover with
glue. It is suggested that the blades are not used for a
24 hour period after gluing to insure that the adhesive
is thoroughly cured.
4.
Lightly sand each rotor blade using 220 grit
sandpaper and remove all sanding dust.
5.
It is suggested that the root and tip of each blade be
sealed prior to covering. We suggest either thick CA
or Aero Gloss clear dope for this task. Sealing these
areas will prevent the exposed wood from absorbing
fuel and oil from the engine’s exhaust, which can
compromise the structural integrity of the rotor
blades.
Blade Covering Installation
1.
Remove the adhesive backing and apply the top blade
covering to the blades starting at the center point of
the leading edge airfoil. Adhere the covering to the
blades starting at the front and slowly moving toward
the trailing edge of the blade, wrapping the additional
length of the covering over the trailing edge and
adhering it to the bottom of the blade as shown in the
diagram.
2.
Remove the adhesive backing and apply the bottom
blade covering to the blades starting at the bottom
edge of the trailing edge. Adhere the covering to the
blade starting at the rear and slowly moving forward
toward the leading edge of the blade, wrapping the
additional length of the covering over the leading edge
and adhering it to the top of the blades as shown in
the diagram.
