Balance Pr
opeller
s
Carefully balance y
our propeller and spare
propellers bef
ore y
ou fly
.An 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
ut vibr
ation ma
y also damage
y
our r
adio receiv

Vibr
ation can also
cause y
our fuel to f
oam, which will, in tur
n, cause
y
our engine to r
u
n hot or quit.
