d) Checking the Engine Function

Attention!

Ensure that no loose parts, such as paper, foil or other objects can be sucked into the propeller during this motor test. Also make sure that the model

is held securely during this test run and that no body parts are within the rotation range or danger area of the propeller.

First start the transmitter, then the model.

Slide the control lever for the engine speed and rudder (see fig. 2, item 10) to the bottom position (engine off). For this, the trim slide for the engine function (see

fig. 2, item 11) has to be in its central position.

If the control stick for the aileron and engine functions is pushed upwards slowly, the propeller starts and slowly increases the rotation speed.

The maximum rotation speed is reached when the control stick is on the top end.

If the engine reacts opposite to the function described above, you may change the direction of the aileron servo with the reverse switch (see fig 2, item 12, "CH3"

switch).

Perform a brief engine test and check the run of the propeller and the propeller catch.

e) Checking the Centre of Gravity

The centre of gravity of the model is preset because of design reasons and is

located approx. 55 mm behind the front edge of the surface (measured in the

centre of the surface).

If the model is lifted at the left and right of this position, it should be in balance

or the nose slightly dropped.

If necessary, the centre of gravity can be shifted by moving the flight battery or

by adding sinkers at the tip of the fuselage or at the tail tip.

If the centre of gravity is moved to the front, this does increase stability but also

decreases the gliding properties of the model.
