Upper figure:
Insert the motor in the chassis according to the sketch and screw the motor carrier to the chassis with four M3x6 screws.
To adjust the tooth backlash, push a small paper strip between the motor pinion and the gear pinion and push the motor
towards the gear. If required, turn the sprocket incl. motor pinion back and forth manually until the gears interlock.
Then remove the paper strip and the four M3x6 screws, and lift the motor with its carrier from the mechanics. Observe that
the motor does not slip on the carrier. Now the two motor attachment screws can be tightened and the motor carrier can be
installed in the mechanics again. Use threadlocker varnish for every screw connection.
If set correctly, the two pinions will securely interlock without catching and without showing too much play. Ideally the
distance between the gears should be 0.1 mm.
The motor connection lines are guided downwards to the speed controller on the chassis outside and connected there.
Lower figure:
Insert the rotor shaft gear and the spacer disc W8x11x2 into the mechanics and push the slightly oiled rotor shaft through
both rotor shaft ball bearings from above. The bore with the lower distance to the shaft end must point down towards the
sprocket.
After connecting the rotor shaft to the sprocket with the screw M3x16, push the collar onto the rotor shaft from above.
Secure the adjustment ring with two grub screws M3x3 that interlock with the prepared groove in the rotor shaft. At correct
assembly, the rotor shaft must turn easily and must not have any vertical play in the mechanics.

Upper figure:
The drawing shows the schematic installation of the two front swash plate servos. Use only high-quality servos with
dimensions 35 x 15 x 30 mm. Always observe the different screw dimensions during installation and use threadlocker
varnish.
Practical advice:
Put the servos into the precise centre position with the remote control before assembly. Then the servo levers are
installed at 90° angles to the housing each. When setting the swash plate linkage later, the servo levers no longer
need to be adjusted in the installed condition.
Lower figure:
The lower figure shows installation of the rear swash plate servo (left drawing) and installation of the tail servo (right
drawing).

Upper figure:
First push the swash plate and then the pre-installed rotor head onto the rotor shaft according to the figure. The rotor head
attachment screw M3x16 has to be pushed through the lower one of the two bores in the rotor shaft.
The pre-installed rotor heat has been equipped with dampener rubbers with a hardness of 75 ex works. Dampener
rubbers with a hardness of 95 can be optionally purchased under the GAUI number 213220.
Lower figure:
The figure shows the schematic setup of the two swash plate tappets.
