tubes in the plastic balancer cases.
When installed in the magnet tubes,
the magnets must be positioned so
they attract, not repel. Secure each of
the magnets in the magnet tubes with
a thumb screw. Do not over-tighten
the screws, as this can deform the
plastic and put the magnets out of
alignment. Slight screw pressure is all
that is required. NOTE: The 6-32
threads will self-tap into the plastic, but
you may cut threads with a 6-32 tap,
making the thumb screw easier to
adjust with your fingertips.
❑ 5. Push and twist the two long base
rods into the sockets in one of the case
halves. Assemble the second case
half to the other ends of the base rods.
Press firmly to seat the rods. Stand the
assembly up as shown.
CAUTION: Do not allow the balancer
rod ends to snap hard against the
magnets, as this will damage the rod
ends or the plastic discs.
❑ 6. Slide the balancing cones onto
the balancer shaft. Place the balancer
shaft between the two magnets. The
balancer shaft will touch one magnet
and the other end will be suspended in
the magnetic field.
For the lowest
possible friction, adjust the magnets
by loosening the thumb screws and
sliding the magnets in or out until the
gap is very small (approximately 1/32"
[0.8mm]) at the shaft end. Secure the
magnets in this position with the thumb
screws. NOTE: The smaller gap
provides lower friction and greater load-
carrying capability.
HOW TO USE YOUR TOP FLITE
PRECISION MAGNETIC BALANCER
The general principle of balancing is
to determine the “heavy side” of an
object and then to either remove
material from the heavy side, or add
weight to the light side (see safety
precautions below). Because the
Top Flite PRECISION MAGNETIC
BALANCER is so nearly frictionless,
you’ll wait a long time for a propeller
to stop swinging; therefore, you
should help the object to nearly stop
by applying light friction to the
balancer shaft with your finger. An
object is perfectly balanced if it can
be stopped and will remain stationary
in
any position.
How to balance SMALL AND MEDIUM
SIZE PROPELLERS: Slide the cones
onto the balancer shaft with the tapered
ends facing each other, trapping the
propeller between the cones. The object
