Center Of Gravity; Canopy Installation - Horizon Hobby Pitts S-2B 50–60cc Manuel D'utilisation

CANOPY INSTALLATION

157. Trim and install the instrument panels in the cockpit.
 A pilot figure can also be installed in the rear seating position.
158. Trim the canopy and use canopy glue to secure the canopy
to the cockpit hatch. Use low-tack tape to hold the canopy in
position until the glue has fully cured.
 The canopy can also be secured using clear tape,
or the provided red tape, so the canopy can be
removed if a pilot figure is to be added later.

CENTER OF GRAVITY

An important part of preparing the aircraft for fl ight is properly balancing the model. 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. When installing the top wing, make sure the
balancing mounts are secured between the wing panels and
center section of the top wing. Use two balance mounts per
side to properly support the weight of the model.
2. Tie a secure knot in the balancing cord. Pass the cord through
the holes in the balancing mounts. Use the aluminum tube to
lift the model. View the model from the side (you may need a
helper). If the model is properly balanced, the stabilizer will
be level.
3. 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.
If the balancing mounts are lost or broken, the recommended center of gravity (CG) location for your model is 5
inches (133mm) behind the leading edge of the top wing center section. Use a felt-tipped pen to make marks under
the top wing center section. Support the plane upright at the marks with your fi ngers or a commercially available
balancing stand. We have tested this model balanced between 4 inches (101.5mm) and 6
to experiment with adjusting the center of gravity until you fi nd a position that suits your fl ying style.
CAUTION: You must adjust your aircraft's center of
gravity and balance your model properly before attempting fl ights.
