2. If you haven’t done so already, install the battery—as
previously suggested, start with the battery positioned as far
forward as it will go.
Recommended
Starting C.G.
2-5/8" [67mm]
Back From Wing LE
at Fuselage Sides
Forward Limit:
2-1/4" [57mm]
Aft Limit:
3" [76 mm]
2-5/8" [67mm]
2-5/8" [67mm]

3. The C.G. is to be marked on the top of the wing so that
you can see where to position your
fi
ngers for lifting the model
for balancing, or better yet, so that you can actually
feel
the
marks. You could use a
fi
ne-point, felt-tip pen, or something
inconspicuous or removable such as pins inserted directly into
the foam that can be removed later. Whatever method you use,
mark the C.G. on the top of the wing where indicated.
NOTE:
The Hellcat may be
fl
own with the C.G. up to 3/8”
[10mm]
ahead
or 3/8” [10mm]
behind
the recommended
balance point. With the Hellcat balanced at the front of the range
it will be more stable, but less maneuverable and heavier due
to the ballast that may be required. With the Hellcat balanced
at the rear of the range the Hellcat will be more maneuverable,
but less stable and quicker to react to your control inputs.
❏
4. Lift the model upside-down with your
fi
ngertips on the
recommended C.G. location you marked.
❏
5. If necessary, shift the battery forward or aft or add stick-on
lead ballast where required to get the model to balance.

6. Once the C.G. has been set, tighten the propeller hub using
a small screwdriver as a torque bar.
MOTOR SAFETY PRECAUTIONS –––––––
Failure to follow these safety precautions may result in severe
injury to yourself and others.
■
Seek the assistance of an experienced pilot if new to electric
motors.
■
Wear safety glasses whenever in the proximity of a spinning
propeller.
■
Do not operate the motor in an area of loose gravel or sand;
the propeller may throw such material in your face or eyes.
■
Keep spectators as well as your own face and body out of
the plane of rotation of the propeller.
■
Keep all loose clothing, long hair or any other loose objects
such as pencils or screwdrivers that may fall out pockets
away from the propeller.
