on both sides of the fuselage. Apply narrow (1/16" [1.5mm])

strips of tape over the lines so you will be able to feel them

when lifting the model with your ﬁ ngers.

This is where your model should balance for the ﬁ rst

ﬂ ights. Later, you may experiment by shifting the C.G. 3/16"

[5mm] forward or 1/4" [6mm] back to change the ﬂ ying

characteristics. Moving the C.G. forward will improve the

smoothness and stability, but the model will then be less

aerobatic (which may be ﬁ ne for less-experienced pilots).

Moving the C.G. aft makes the model more maneuverable

and aerobatic for experienced pilots. In any case, start at

the recommended balance point and do not at any time

balance the model outside the speciﬁ ed range.

2. Place the motor battery on the top of the fuselage on

the recommended CG. Lift the model from the bottom at the

recommended CG.

❏

3. If the tail drops, the model is "tail heavy." Move the

motor battery forward to get the model to balance. If the nose

drops, the model is "nose heavy." Move the motor battery aft.

Once you have determined the battery location required to

balance the plane, note the location and where the battery

would need to be attached on the bottom of the fuselage.

4. Apply the remaining hook and loop material to the side

of the fuselage at the approximate location for the motor

battery. Attach an opposite piece of hook and loop material

to the battery. Trial ﬁ t the motor battery to the side of the

fuselage and recheck the CG.

PRO TIP

For the most demanding rolling maneuvers, some of our

team pilots prefer to use some additional carbon tail bracing.

We have included additional lengths of carbon rods and

short ABS brace doublers that allows you to set-up your

Extra 330SC like the pros.

❏

1. Position one of the 1 × 170mm carbon rods so that

it is 3" [76mm] from the vertical fuselage, on the carbon

strip in the stabilizer and below the 4

the angle and cut a small slot in front of the carbon strip

in the stabilizer and ¼" [6.5mm] above the bottom of the

vertical fuselage.

❏

2. Slide two of the short ABS brace doublers onto the

170mm carbon rod. Insert the rod into the slots and slide one

of the doublers onto the stabilizer. Use foam safe CA to glue

the brace doubler and carbon rod to the stabilizer. Do not

glue it to the vertical fuselage.
