Balancing The Centre Of Gravity - Carson 500505023 Sbach 342 Instruction Manual

i. Balancing the centre of gravity
An airplane's centre of gravity is designed to be in a certain relation to
its lifting areas and the Sbach 342 it is set up correctly on delivery. The
margin at which the centre of gravity may move in relation to the ideal
set up is very small. You can check the centre of gravity of the
Sbach 342 by holding it up at the points shown (140 mm from the
rear edge of the wing) with two fingers. It should then slightly swing
GB
around the horizontal position and not be inclined to the front or rear.
Centre of gravity

If the nose or tail sections have a tendency to tilt downwards, the
weight is biased in this direction. Occasionally the centre of gravity
of the aeroplane may have to be corrected e.g. after a repair, by the
addition of small weights. These should be applied using double
sided tape and should be equally balanced. A centre of gravity which
is too far rearward (nose too light) will make flying difficult and needs
to be corrected.
