Technical Data - Conrad PA-28 Operating Instructions Manual

Adjustment
Adjust the wings, the ele-
vator tail and the vertical
tail. The wings must be
straight to achieve a stable
flight path. Every bend
negatively influences the
flight characteristics.
The model is ready for
take-off.
Winding up the rubber
band motor
Before the start the rubber
band must be wound up
by turning the propeller
clockwise about 200-220
times.
Never over wind the rub-
ber, it might break.
Launching the model airplane
The model aircraft can be launched in different ways. Hold the propeller and throw the model in
to the wind as illustrated.
The model should only be used in large open areas without any hazardous obstacles.
Trimming in the Flight
The test flight is made easier by starting the model in to the wind.
In the following illustration the various horizontal flight characteristics are shown.
( a ) The model flies a right hand bend. This can be adjusted by changing the vertical rudder.
Push the vertical rudder slightly to the left, to counteract flight to the right.
( b ) The model flies a left hand bend. This can be adjusted by changing the vertical rudder. Push
the rudder slightly to the right, to counteract flight to the left.
Now the model should fly straight forwards. Ideal flight characteristics.
In the following illustration the various horizontal flight characteristics are shown.
( a ) The model flies upwards and falls downwards rapidly. This can be adjusted by changing the
elevator. Push the elevator slightly down, to counteract climbing flight.
( d ) Model dives downwards. This can be adjusted by changing the elevator. Push the elevator
slightly upwards, to counteract diving flight.
Now the model should fly straight forwards. Ideal flight characteristics.
Setting the flight direction
On this model you can determine the direction of flight by bending the elevator and the vertical
rudder. Furthermore, the ailerons on the wings can be adjusted. This increases the declination.
