GRAUPNER Elektro-UHU Instructions De Montage page 24

Use a mini fine-nose saw to cut a tunnel in the motor pylon for the motor cables. We
recommend that you remove the support wheels before tackling the next stage.
Glue the SPEED 400 PLUS motor unit in place as shown in the illustration. Caution:
ensure that the front end of the motor is mounted low enough: the circuit board of the
PLUS speed controller should not project above the line of the pylon. Take care also
to align the motor exactly "straight ahead" when viewed from above. Don't fit the
propeller until you have completed the initial motor test-runs.
The picture shows the RC receiving system and NiMH battery installed in the
fuselage. Caution: the receiver socket sequence is not as described in the operating
instructions supplied with the X-306 (included in Order No. 9400.200), since the
standard instructions are primarily intended for RC model cars. For this reason
please observe the following operating notes which apply to your new Elektro-UHU
model aircraft.

RC installation
The building instructions and the pictures refer to the X-306 FM radio control system.
If you are fitting different RC equipment, please refer to the operating instructions
supplied with the set.
You have already installed the servos in the fuselage. Connect the rudder servo to
receiver socket 1, the elevator servo to socket 2, and the SPEED PLUS motor unit to
socket 3. Press the receiver aerial into the channel provided, and run it to the tail of
the model.
Caution: the next step is to test the power system, but be sure to switch the
transmitter on first, and check that the rotary switch on the X-306 transmitter
(function 3) is in the "back" position (corresponding to motor OFF) before you
connect the NiMH or LiPo flight battery.
Charge up the batteries in the transmitter, then check all the working systems from
the transmitter: move the right-hand transmitter stick (function 1) to the right, and the
rudder should also deflect to the right (as seen from the tail). If you pull the left-hand
stick (function 2) back towards you, the elevator should deflect up. If either control
system works the wrong way round, operate the appropriate small slide-switch at
bottom left on the transmitter to reverse the direction of servo rotation.
The control surface travels will automatically be correct provided that you have used
the stated lever lengths and set the servo travels to 100%. The elevator travel should
be 8 mm up and 8 mm down, measured at the outboard end. The rudder travel
should be 10 mm to either side of neutral, measured at the bottom.
Decals
Cut out the individual decals and apply them to the model in the arrangement shown
in the illustration.
Colour the canopy using a blue felt-tip pen, leaving the frame area white. Check that
the ink does not affect the foam before applying it.
The illustration shows the undercarriage decals (31) and (32) which are applied to the
wing and fuselage if the undercarriage is not fitted.
