K&S 818 head FBL

This is a rare version of k&s 818 released in the '90. Like the "normal" 818 head it has the particular flapping system of blades. If a blade holder go up the holder of other side, go dowm. The two sides are connected by a particular sled.

The big difference is that this head is a true flybarless system, a great innovation for that time. This head can be fitted in any 60 class helicopter for better performance.
