Balance the Model (C.G.) At this stage the model should be completely ready- to-fly with all of the components installed including the engine
, m
uffler
, propeller
, spinner
, landing gear
and wheels
.
❏
1.
If using a Great Planes C
.G.
Machine to balance
the model, set the r
u
lers to 3" [76mm].
If not using a
C
.G.
Machine
, use a fine-point f
e
lt-tip pen or 1/8"
wide tape to accur
ately mar
k the recommended C

(center of g
ra
vity
, or
“balance point”) on the bottom of
the wing 3" [76mm] bac

both sides of the fuselage
.

Place the model on a Great Planes CG
Machine
, or lift it at the balance point y
ou mar
k
ed on
both sides of the fuselage
.
Note whether the nose or
tail drops
.
If the tail drops
, the model is
“tail hea

and w
eight m
ust be added to the nose to balance
.
If,
ho
w

Add nose or tail w
eight to balance the model.
If
nose w

Do not rely upon the adhesiv

manently hold it in place
.
O
ve
r
time
, fuel and e
xhaust residue ma
y soften the adhesiv
e
and cause the w

all off
.
Use #2 sheet metal
scre

, R
TV silicone or epo
xy to per
manently hold the
w
eight in place
.
Balance the Pr
opeller
Carefully balance y
our propeller and spare propellers
bef
ore y
ou fly
.
A
n unbalanced prop can be the single
most significant cause of vibr
ation that can damage
y
our model.
Not only will engine mounting scre
ws and
bolts loosen, possib
ly with disastrous eff
ect, b
u
t
vibr
ation can also cause y
our fuel to f
oam, which will,
in tur
n, cause y
our engine to r
un hot or quit.

T
op Flite Precision Magnetic Prop Balancer

(T
OPQ5700) in the w
o
