12. The First Flight
Before the first start, the flight battery must be charged according to the instructions in the section "Charging the Flight
Battery". Use a battery tester to test the remaining capacity of the transmitter batteries.
After another quick check of the function of the motors, your model is ready for its first flight. Find a suitable area for
flying, with enough space and without obstacles. Wait for a day with low or no wind.
a) Range Test
First perform a range test for the remote control system on the flight area. Switch on the remote control and then the
receiver. Now check the range by having someone assist you by securely holding the model, and walk away from the
model slowly. The control functions should work without any problems up to a distance of at least 50 m.
b) Take-Off
Hand start:
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 the hand. This way, you have both hands free for steering and can focus
fully on the model.
The start helper will take the model at the end of the verti-
cal fuselage plate from above between thumb and forefin-
ger (see finger indication in figure 13). The fuselage tip of
the model must point slightly upwards when it is held.
Our advice: In order to be able to distinctly see the flight
attitude of your model, you should stand at a short distance
behind the person assisting you and look into the flight di-
rection of the starting model.
Attention!
Always start against the wind, even if there is barely any wind at all.
Now accelerate slowly and let the motors run at full output. The start helper will accelerate the model in a curved
movement with his arm stretched out and then release it. The model must point slightly upward with its tip at all times
(see figure 13) and the wings must be aligned horizontally.
Ground start:
If a level, smooth and large enough area is available, the model can be started from the ground. Align the model at the
starting point so that the tip of its fuselage points against the wind and stand behind the model. Accelerate speedily
and ensure that the model does not break away to the side. After a short rolling distance, the model will lift off of the
ground on its own.
The model will rise up at a flat angle with the rechargeable battery fully charged and if the start is conducted correctly.
Try to steer as little as possible at first, so that the model gains altitude in a straight flight. Only steer the model if it
changes its flight attitude by itself and is about to fly a curve.
Let the model rise to a sufficient height before you initiate the first curve. Also do not fly too high or too far away. You
should always be able to see the flight position of your model well. When the desired altitude is reached, throttle the
motors so that your model continues to fly at the same altitude.
