Thorough maintenance
1. Check if any screws have loosened or components are no longer firmly screwed on.
2. Check the tooth backlash between the motor pinion and the main pinion. Particularly check if the motor has come loose
so that the teeth of the two pinions no longer interlock cleanly.
3. Check the tooth backlash at the tail rotor drive. The pinions must force-interlock but still run smoothly.
4. Observe clean run of the various shafts. Even slight ground contact of the rotor blades may lead to considerable shaft
deformation.
5. Check all ball bearings for clean run. Bearings that issue a "rolling" or "crunching" feel when operated manually must
be replaced as well as any visibly damaged ball bearings.
6. Check the auxiliary paddles. The paddles always have to be aligned precisely (see page 12, top figure), and the paddle
rod must not be deformed.

Lower figure:
The figure shows disassembly of the main gear. The individual work steps are marked with numbers in the drawing.
1. Remove the main rotor shaft first (see top).
2. Remove the collar #208368 at the bottom of the main gear.
3. Remove the three screws #208855 and remove the centre piece #208360.
4. Remove the spacer disc #208883.
5. After removing the screws #208858, the bottom piece #208358 and the freewheel can be removed.
Attention!
To insert the freewheel again correctly alter, we recommend marking the lower side with a fibre pen. For assembly,
the centre piece #208360 must be oiled according to the drawing.
