17. The First Flight
Before the first use, the flight battery must be charged as instructed in chapter 10.
Use a battery tester to test the remaining capacity of the transmitter batteries.
After once again briefly reviewing the motor function and deflections of the elevator and rudder, the model is ready
for its first flight.
Select a suitable room to operate your model. We recommend that you use a large meadow, a sports or model flight
court or a large storage hall or gym for your first attempts at flying. If you are flying outdoors for the first time, wait for
a day with little to no wind.
Important!
The motor runtime depends on the flying style and the outdoor temperatures. At low outdoor temperatures,
the battery performance will generally drop.
To protect the rechargeable battery from deep discharge, the electronics switch off the motor when a specific
residual capacity of the rechargeable battery is reached. Control of the model via the rudder function is
possible for a few more minutes from this time onwards.
We therefore recommend ending the flight after 2-3 minutes of gliding at the latest after the motor switches
off due to undervoltage recognition, and to charge the battery again. Non-observance will cause deep
discharge of the rechargeable battery and irreparable damage. Additionally, the receiver system will cease
operation due to undervoltage. The model can thus no longer be controlled and will crash. Loss of guaran-
tee/warranty!
a) Take-Off
Generally, it is easily possible to start the model on your own. For the first flight, however, we still recommend using
a launch helper to launch the model from his hand. This way, you have both hands free for steering and can focus
fully on the model.
Like the start, the touch-down outdoors should always be done against the wind. Do not start from the centre of the
room indoors, but from a corner. This way, you have enough space for flying a large circle in the room.
Our advice:
In order to be able to distinctly see the flight attitude of your model, you should stand to the side and behind
the person assisting you and look into the flight direction of the starting model.
The start helper takes the model at the fuselage below the wings with his thumb and first finger. Now accelerate slowly
and let the motor run at full output. The launch helper then releases the model straight forwards with a gentle push.
The model should now rise at a flat angle. You may need to reduce the motor speed a little for this. Try to steer as
little as possible. Only steer the model if it changes its flight attitude by itself and e.g. flies a curve, ascends too high
or is about to nose-dive.
To sensitively correct the flight attitude and to carry out specific changes of direction in normal flight attitude, short and
limited movements of the control stick on the transmitter are sufficient.
Once the desired flight altitude is reached, reduce the motor performance or switch off the motor. When the motor
is switched off, the propeller will fold in and thus improve the aerodynamic flight properties. Initiate the first curve.
