8. Ballast:
As ballast we use lead
balls
from the
fishing shop
. You can
easily assemble and vary this kind of ballast.
The balls are strung on a
steel wire of 1,0mm diameter
. Bend
the end of the wire to a small hook. With this
hook
the ballast
pack can be
locked
on the radio board.
To locate the exact position of the ballast inside the fuselage,
lay the model on a
device for measuring the centre of gravity
(see picture). Move the ballast until you get the desired centre
of gravity.
When bending the wire you should make sure that you
don’t
create 180 ° curves
, as the wire may break then.
Put a drop of thin
super glue onto
the first and the last lead
ball
to fix their position. As you must curve the ball chain for
threading it into the ballast tube, bend the wire in the desired
curvature when you glue the balls.
Insert the ballast through the left opening of the fuselage
into
the ballast tube
.
The hook of the ballast package is
locked in the servo board
.
