Fenestron petrol mechanics

Ord.No. 1002/29

Fenestron petrol mechanics

• gear ratio 9.09 : 1
• counter clockwise rotation system
• without engine, not pre assembled

Because of the gear ratio of 9.09 : 1, the noise level is at a minimum, even though the rotor diameter is 1680 mm. This also results in a higher RPM of the fenestron.
Do not exceed the permitted rotor rpm of 1350 (this equals to approximately 7500 rpm of the fenestron). Don't get fooled by the low operating noise, it is just hiding the actual rpm.

Without motor and petrol components (see Ord.No. 26/100).
