The First Flight Of Your Helicopter - GRAUPNER heim NH90 Mode D'emploi

The first flight of your helicopter

1. Put the helicopter on a smooth ground which allows the model to slide and turn around.
2. Set the throttle stick and its trim lever to the lowest position (power off) and all servo reverse
switches to normal position.
3. Turn on the transmitter first. Connect the battery pack to the Control-box. The LED will first
blink red and green. Wait until it lights up green.
4. Gently push the throttle up until the wheels are about to leave the ground and the machine
will turn to left or right.
Minor corrections of the yaw trim are done by using the trim lever of the transmitter. Major ad-
justments have to be done using the „Gain" trim (yaw trim) in the control box.
If the machine is turning to the left, land the machine and use a small screwdriver to turn the
"Gain" trim clockwise, and vice versa.
The new setup becomes active after disconnecting an reconnecting the battery!
Try again until the machine will not turn to left or right on the ground when it is about to take
off.
5. Never push the throttle stick to full power or push it abruptly. Continue to practice "take off
and land" until you become familiar.
6. Increase power little by little and let the machine take off up to 30-50 cm. This is the most dif-
ficult stage of flying as the "ground effect" makes the helicopter become unsteady. The ma-
chine will shift away in unexpected directions. Watch and observe the direction it shifts to-
ward. If it is shifting to the left, correct it by pushing the aileron trim lever a little to the right. If
it is shifting backwards, push the elevator trim lever a little forward. If it turns to the right,
push the rudder trim lever a little to the left. And so on.
7. Then, gently push the throttle stick forward a little more to lift up the machine to your knee
height. You have to ceaselessly correct the machine not to shift away by simultaneously push
or pull the elevator, aileron and rudder sticks to eliminate the shift.
8. Next, push the throttle stick further forward to raise the helicopter to your eye height. If the
machine should shift in any direction, gently move the rudder, elevator and aileron sticks in
the opposite direction of the movement to return the machine to its original position. Con-
gratulations! You have succeeded in "hovering".
9. Now, you can fly the mini heli in different directions, i.e. fly forward or backward, fly to the left
or to the right, fly higher or lower, etc. After practicing enough, you can do more, such as
pirouette (rotating in hover), square pattern, hovering "8", landing on designated spot, etc.
10. If in flight the LED on the model's fuselage begins to blink blue, this indicates the battery to
get empty. Land immediately to avoid a crash!
11. After having landed generally disconnect the battery of the model first, then turn off your
transmitter.
12. Should the helicopter crash, immediately set the throttle stick and its trim lever to the lowest
position and disconnect the battery first, then turn off your transmitter to avoid damage of the
helicopter and/or the electronics and radios.
