Checking The Centre Of Gravity In Flight - Reely Mini Hawk Bedienungsanleitung

When attempting your first vertical landing, fly the model to the landing point in the same way as during standard
landing. When the altitude is low enough, press the V-LAND switch and follow the model.
If the model raises the tip of the fuselage much more than shown in Figure 29, this means that the flight speed is too
high to initiate vertical landing.
If the model fails to raise the tip of the fuselage despite the raised tail unit, the flight speed is too low.
Practise vertical landing at a low altitude until the model behaves as shown in Figure 29 and you get a feel for the right
landing approach speed. You can then gradually increase the starting altitude for vertical landing.
Our tip from experience:
In any case, we recommend that you resort to standard landing whenever possible for it is much more
gentle for the model.
Upon landing, unplug the flight battery from the model and switch off the transmitter. Use a LiPo checker to check
the remaining charge of the flight battery. It should not be less than 30%. A deep discharge can permanently damage
the flight battery.
If necessary, you can readjust the aileron linkage such that the model flies straight and set the digital trim on the
transmitter back to the centre position.
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 30, 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 30, sketch B).
If the model fails automatically to perform a curve and
does so only by pulling the elevator joystick, this means
that the centre of gravity is too far back (see Figure 30,
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.
