Heavier fuselage models can make use of the aluminium tail rotor system, since the higher take-off weight and a larger torque must be compensated. In addition, the aluminium tail rotor has the advantage that the direction of rotation can be reversed, for example, when the tail rotor is to be mounted on the right in the direction of flight.
The aluminium tail rotor, which is used here, differs by the use of a tail rotor shaft with 6 mm diameter, which in turn, all further accessories on ø 6 mm are adapted.
The
Aluminium Premium version is equipped with the following tuning parts:

- Aluminium Control Bridge
- Aluminium Bellcrank
These parts increase the stability of the tail rotor abutment components and are resistant to high temperatures, e.g. Exhaust gases of the turbine models.
- Spiral toothed bevel gears
These bevel gears significantly reduce running noise and increase tail rotor speed by 6%.
Please also remember the order of the tail rotor input shaft with the suitable coupling type and suitable tail rotor blades.
Tail rotor supplied un-assembled.
