Decal Installation; Center Of Gravity - Horizon Hobby HANGAR 9 Carbon Cub FX-3 Manuel D'utilisation

187. Place a drop of thread lock on the threads near the fi tting,
then tighten the nut over the thread lock and against the
fi tting.
188. Slide the outer strut fairing on the strut. The strut will need to
be disconnected to do so.
 The outer strut fairings are optional as they
are a non-functional scale detail.
189. The fairing is secured using six M2 x 6 sheet metal screws.
Use a drill and 1/16-inch (1.5mm) drill bit to drill the holes to
mount the fairing. Make sure to prepare each hole using thin
CA before installing the screws.

DECAL INSTALLATION

190. Apply the decals to your model using the photos located
in this section of the manual and the box art from your
model. Use a spray bottle and a drop of dish washing liquid
or glass cleaner sprayed in the location of the decal to
allow repositioning of the decal. Use a paper towel as a
squeegee to remove excess water from under the decal.
Allow the model to rest overnight so the remaining water can
evaporate.

CENTER OF GRAVITY

An important part of preparing the aircraft for fl ight is properly balancing the model. The Center of Gravity range
supplied here is a guideline based on testing. Deviation from the measurements we provide is possible and may result
in a model that suits your fl ying style better. Start with the recommended Center of Gravity, then feel free to experiment
with different balance points. We advise adjusting progressively and cautiously.
1. When balancing your model, make sure it is assembled and ready for fl ight but with the wings and wing struts
removed. The tail section and all tail supports should be installed.
2. The recommended Center of Gravity (CG) location for your model is 4
of the wing. Mark the location on the sides of the fuselage using a felt-tipped pen.
3. Hold the plane upright, placing your fi ngers at the marks you made on the fuselage. View the model from the side
(you may need a helper). If the model is properly balanced, the stabilizer will be level.
4. If either the tail or the nose hangs low, then the opposite end needs to be heavier. To reduce the amount of weight
you need to add, fi rst reposition batteries or other accessories inside the fuselage as far forward or back as
needed to improve the balance. If you must add weights, always secure them well so they cannot move during
fl ight.
 The overall CG range for this model is 1
measurement listed above and then adjusting the Center of Gravity to suit your flying style.
 Due to the short nose and long tail of the Carbon Cub FX-3, it is not uncommon for them to require
nose weight in order to achieve the correct balance to suit some flying styles. For a soft and sedate
"feel" it may be necessary to add between 2–4 lbs (0.91–1.8 kg) to the front of the aircraft.
CAUTION: You must adjust your aircraft's center of
gravity and balance your model properly before attempting fl ights.
