13. The First Flight
a) Range Test
Before the rst use, the ight battery must be charged according to the manufacturer‘s instructions. The batteries/
rechargeable batteries in the transmitter must be inspected for voltage position (e.g. with a battery tester). First
perform a range test for the remote control system in the ight area. Switch on the remote control and then the
receiver. Now check the range by having a helper hold the model if possible and moving away from the model. For
this, observe the operating instructions for the remote control system.
After once again briey reviewing the motor function and deections of the elevator and rudder and the two ailerons/
wing aps, the model is ready for its rst ight.
Select suitable ight area to operate your model. We recommend a model ight eld or large meadow for your rst
ight attempts. Wait for a day with low or no wind. If you have no or insufcient knowledge of how to control ight
models ask an experienced ight model constructor for help.
b) The Start
Generally, it is easily possible to start the model on your own. For the rst ight, 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. You should always start and land against the wind.
Our advice:
In order to be able to distinctly see the ight attitude of your model, you should stand to the side and
behind the person assisting you and look into the ight direction of the starting model.
The start helper takes the model at the fuselage below the wings with his thumb and rst nger. Now switch on the
motor. The launch helper then releases the model straight forwards with a gentle push.
The model should now rise at a at angle. You may have to correct that ight position a little with the elevator. Try to
steer as little as possible. Only steer the model if it changes its ight attitude strongly and e.g. ies a curve, ascends
too high or is about to nose-dive.
To sensitively correct the ight attitude and to carry out specic changes of direction in normal ight attitude, short
and limited movements of the control stick on the transmitter are sufcient.
Once the desired ight altitude is reached, switch off the motor and initiate the rst curve.
