Black Magic Mechanics

In the pictures you can see the latest development of the 'black magic' dome mechanics. By popular demand, there is now tail rotor RPM’s from under 4000 to 10,000 rpm (Fenestron) are now possible.
The mechanics can also be rotated 180 degrees (motor front / rear) installed because the rear rotor drive can also be turned.
The gears are built up closed as far as possible and are very strong.
Ratio’s from 12:1 to 21:1 are possible . For e motors with a maximum diameter of 65 mm and 30 mm hole circle up to 10 Kw . No limit on engine length .
This is light industrial mechanics which was built modularly, the direct use of main shafts with 12/15/and 20 mm is possible.
Each mechanical kit is individually manufactured by XXL and adapted to your desired requirements.
Due to the relatively light weight and the robustness of the components, this full metal mechanics is universal for all XXL models from 2 m or can be adjusted.
The main difference to the 'blue magic mechanics' is the stern drive. This one is missing from the blue one, where the rear is driven with a separate electric motor.
