Checking The Centre Of Gravity In Flight - Reely Wild Hawk 3.0 Bedienungsanleitung

f) Checking the centre of gravity in flight
When you have a firm grip on your model after a couple of flights, you can optimise the flight performance by checking
the centre of gravity in flight and optimising it if necessary. You would rather choose a windless day for that purpose.
Let the model ascend to approx. 100 m and then switch off the motor.
With the motor switched off, the model should fly straight for a short time without loss of altitude. If necessary, perform
a curve such that you can view your model from the side as it flies at a 90° angle to the viewing direction. Then briefly
push the elevator joystick forward so that the model flies downwards at an angle of approx. 30°.
Without manipulating the elevator joystick, the model
should automatically perform a gentle curve and then fly
straight for a while (see Figure 35, sketch A). In this case,
the centre of gravity is set correctly.
If the model automatically performs a narrow curve and
then quickly raises the tip of the fuselage upwards, this
means that the centre of gravity is too far forward (see
Figure 35, sketch B).
If the model fails automatically to perform a curve and
Figure 35
does so only by pulling the elevator joystick, this means
that the centre of gravity is too far back (see Figure 35,
sketch C).
If centre of gravity correction requires shifting the flight battery, the elevator trim must first be checked or adjusted
before the next test.
