f) Checking the Centre of Gravity
• The centre of gravity of the model is preset due
to design reasons and is located approx. 55
mm behind the front edge of the wing.
When the model is lifted at this point right and
left from the fuselage, it should be horizontal.
• If necessary, the centre of gravity can be shifted
by adding sinkers at the tip of the fuselage or
at the tail strike.
However, only experienced pilots should modify the position of the centre of gravity in
order to adapt selectively the model airplane performance to their expectations and
steering habits.
