Scale 4 blade head

Loose joint head, the BO-105 head modeled.

The aim of the development of this head was to design it as true function, but it should absorb the tensile forces of the leaves not a "Bendix bones."

Although it has already given model heads with this component, but this requires regular monitoring and care in assembly and adjustment.
The original has this component, except for each blade holder only 2 needle (cylindrical roller) bearings which receive no axial tensile forces. This is only the Bendix
responsible. However, this element is sensitive to the maximum angle of rotation, over-rotation this element destroyed without directly something to notice it.
Therefore, our head has a slightly different structure central piece. There, a thrust bearing is installed, this can be something greater than the standard T-Rex450 and even record higher tensile forces than the 450 DFC head.
For assembly, the central piece of 4 identical parts screwed together.
The pulling force of the thrust sheets is introduced into the central piece Duch a steel shaft from the blade holder. The transverse mounting of the blade holder shaft take 2 good sized radial bearing (needle bearing is in size just too expensive).

     CNC machined parts made ??of EN AW 7075
     Axis from high tensile steel
     Japanese high-quality miniature ball bearings
     Ball joints, linkages
     Swashplate aluminum CFRP (MH-450 TSM-MC)
     Distance between the blade screws 87mm

it is a virtual swashplate rotation of about 42 ° necessary.

Currently running flight tests with this head, but we do not now expect surprises and think that can start the mass production soon.

BTW: The Jagged Fringe, which one is have some "Scale heads" the way a bearing cap on the central piece and does not rotate with;-)
