Balance the Propeller

Take a few minutes to balance your propeller and a spare

propeller before you ﬂ y. A balanced propeller will help the

motor run smoothly and efﬁ ciently. A severely unbalanced

propeller can cause enough vibration to stress glue joints

and cause screws to loosen.

If the propeller is unbalanced, use a single-edge razor blade

or a hobby knife to scrape material off the heavy blade until

you can get the propeller to balance.

Balance the Model (C.G.)

More than any other factor, the C.G. (center of gravity/balance

point) can have the greatest effect on how a model ﬂ ies. If

you value your model and wish to enjoy it for many ﬂ ights,

DO NOT OVERLOOK THIS IMPORTANT PROCEDURE.

3/8"

A model that is not properly balanced may be unstable and

possibly unﬂ yable.

At this stage the model should be in ready-to-ﬂ y condition

with all of the systems in place including the motor, complete

radio system, ESC, propeller and battery.

1. With the wings held to the fuselage with a couple of rubber

bands, lift the model by your ﬁ ngers placed on the middle

lines on the bottom of the wing marking the recommended

starting balance point.

❏

2. This is where your Falcon should balance for the ﬁ rst

ﬂ ights. Later, you may experiment by shifting the C.G. 3/8"

[10mm] forward or 3/8" [10mm] back to change the ﬂ ying

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

smoothness and stability and allow the Falcon to perform

tighter turns, but the model will ﬂ y slightly faster. A slightly

more-forward C.G. is also usually desirable for ﬂ ying outdoors

where higher throttle settings are normally used. Moving

the C.G. aft allows the Falcon to ﬂ y more slowly, but will

require slightly more pilot control in tightly-banked turns. A

slightly more-aft C.G. is usually desirable for indoor ﬂ ying

for slower speed. In any case, start at the recommended

balance point and do not at any time balance the model

outside the speciﬁ ed range.

If the model is balanced properly it should rest level when

viewed from the side. If the tail is down the model is "tail-heavy"

and nose weight will be required. If the nose drops the model

is "nose-heavy" and tail weight will be required. (It is typical to

require approximately 1/4 oz. [7g] of nose ballast to achieve

a good starting C.G.)
