18.5.3 Gyro reset
It is good practice to reset the gyros before every flight by
following section ”19.2 Resetting flight leveling gyro” on
page 51.
18.5.4 Turning orientation LEDs on and off
The orientation LEDs (7) can be turned on and off via the transmitter. Turn them on or off
beforeyoustarttheengines.

depending on their state.

The procedure for starting and stopping the motors is mode dependent.
18.5.5.1 Mode 1
1. StarttheenginesbycarefullymovingtheELEVATOR/RUDDERleverdiagonallyinto
the left bottom corner (see [ Fig. 26 ]).Holdthispositionuntilthemotorsturnon.Itmay

2. Turnthemotorsoffbyrepeatingthedescribedsteps.
18.5.5.2 Mode 2
1. StartthemotorsbycarefullymovingtheTHROTTLE/RUDDERleverdiagonallyinto
the left bottom corner (see [ Fig. 27 ]).Holdthispositionuntilthemotorsturnon.

18.5.6 Directional checks
It is crucial to confirm the proper functioning of the
transmitter before every flight.
> Test AILERON and ELEVATOR for their intended behaviour.
> Test THROTTLE and RUDDER for their intended behaviour.
18.5.7 Taking off
> Increase THROTTLE until the »Xtreme is at least 50 cm above the ground. At this
height,youhavepassedtheso-calledGROUND EFFECT and the »Xtreme is more
stableinitsightpositionandcanbecontrolledmoreeasily.
> Youhavenowmanagedthecriticalpartandcanfamiliarizeyourselfwiththe»Xtreme
byslowandcarefulthrottlecontrollingmotions.
During flight close above the ground and during take-off,
turbulence and air flow can be experienced which may
affect the »Xtreme. A quicker response to the controlling
motions and slight swerving of the »Xtreme forwards,
backwards or to the side may result from this. This so-
called ground effect is no longer present starting at a flight
altitude of approx. 50 cm.
