K&S 818 rc helicopter rotor head.

From '90 years this interesting head released by japanease K&S for 60 class helicopter. It is a full aluminium head.

Of couse you can use this head on heli of that time so Kalt 60 and Hirobo Freya of course. The most interesting thing is the flapping system of blades. So If a blade go up the blade of other side go dowm. The two sides are connected by a particular sled.

I think this system is very helpful during movement, of helicopter, in the hovering.
