Check the C.G. (Center of Gravity)
The C.G. (Center of Gravity) is the location on the wing
where the model balances and has a great effect on how
the plane will fl y. If the C.G. is too far aft (tail heavy), the
model will be too responsive. If the C.G. is too far forward
(nose heavy), the model will not be responsive enough. As
provided to you, your Corsair should already be properly
balanced, or very nearly properly balanced, but it’s a good
idea to check the balance just in case. Follow the instructions
to make sure the model is balanced properly and the C.G.
is in the correct location.
❏
1. Install the battery hatch (the battery is still installed in
the battery compartment).
❏
2. On the top of the wing, place a mark 2-7/8" (73 mm) from
the leading edge or use the panel lines as a reference. Place
your fi ngers on these marks and lift the plane upside down.
The fuselage should remain level – it may be helpful to have
an assistant view the plane from the side. If the fuselage does
not rest level, try moving your fi ngers under the wing. Your
fi ngers can be moved forward up to 1/4" [6.4 mm] or aft up to
5/16" [ 8 mm]. As long as the fuselage is level with your fi ngers
within the range, the balance is acceptable, and the plane is
ready to fl y. However, even if after moving your fi ngers the
acceptable 1/4" [6.4 mm] forward, the nose remains low, tail
weight will be required. Or, even if after moving your fi ngers
the acceptable 5/16" [ 8 mm] aft, the tail remains low, nose
weight will be required. Balance the plane as instructed below.
Note: Even if your Corsair balances perfectly on the
recommended balance point, later you may wish to change
its fl ying characteristics by moving the C.G. forward or aft.
Moving the C.G. forward (nose heavy) will make the plane
more stable which may be better for windier days, but this will
also make it less maneuverable. Moving the C.G. back (tail
heavy) will make the plane more maneuverable which is good
for experienced pilots who wish to perform aerobatics. In any
regard, start at the recommended balance point and never
fl y the model with the C.G. outside the recommended range.
❏
3. Determine the amount of weight required by placing
segments of Great Planes stick-on lead (GPMQ4485) or similar
weight, over the cowl or tail, but do not attach it yet.
❏
4. Once the plane balances and you know how much lead
will be required, permanently stick it into position. The best
place to add nose weight is to remove the propeller and dummy
engine and place the weight inside the cowl. If tail weight is
required, simply attach it to the side of the fuselage, under the
horizontal stabilizer.
