Start by hand
During the flight:
The flight direction is controlled by rudder and aileron. The model will be positioned in direction by moving over the
mainwing. When you fly to narrow turns, the model begins to sink slightly. You can control this by giving a little more
elevator.
Rise and sink is controlled by the elevator. Note that your model may tilt if the rising angle becomes to high due to the
loss of torque. If that happens put the controll sticks to neutral position. Due to its contruction, the plane will stabilize
itself. Especially when you fly near the ground take care that you fly allways fast enough.
Trim:
If your model flies corners without steering use the trim function of the
rudder and aileron to make sure that the plane flies straight on. If the
model rises or sinks without steering use the trim function of the elevator
to control that.
Maybe it's necessary to change the center of gravity
(as mentioned below!)
How to land:
As soon as the plane won't rise anymore with running Motor or the Motor
is stalled by the electronic speed control or power switch, you should
begin the landing. Keep the plane on a height of approx. 30m and pass
the pilot with the wind in the back of the plane. At approx. 20m height
turn the aircraft 180° and fly against the wind. Right before
ground-contact slightly pull the elevator to flatten your landing-angle.
Adjust the center of gravity
With the motor stalled and the elevator in neutral position the airplane
should glide with a slight sinking. If it's flying up and down all the time,
the center of gravity is to far back. Position the battery a little more to
the front. If it's sinking to fast the center of gravity is to far in the front.
Position the battery a little more to the back. Always use small steps
and save the battery from moving by placing foam dices around the battery
Flight instructions
Take off:
Check winddirection and windspeed by using a frequency flag.
Please don't start with strong winds. You may perhaps loose control of your plane!
You can launch the plane in two different ways: By hand or from the ground on a hard surface.
Always start against the wind! Set the throttle control stick to off position. Push the red start button on the
fuselage to allow the motor to turn. Set the speed control to full throttle and throw the airplane against the wind.
When starting from the ground move the airplane down a straight line by using the rudder. When the plane has
reached enough speed slightly pull the elevator.
No matter what kind of launching method you prefer keep care that the speed is high enough!
Always be very careful when flying your airplane.
