Friction on Rotorhead
This follows with the thought of loosening ball links. There are
other parts of your heli rotorhead that you will need to be
concerned with. Any moving pieces, whether it pivots, rotates,
slides, whatever, should move freely. Care you be taken not to
overdo it, as too loose isn't necessarily better than too
tight. Another thing to think of is what should be loose before you
put the entire head together, just to take it apart again. And yes,
you will take it apart a few times.
Flybar Seesaw
This is a key part that has two different places that need
work.
1. The pivot where the flybar seesaw sits on the rotorhead. You
might have to widen the holes where it adjoins the rotorhead. You
will probably have to do a little work on the rotorhead itself,
which would enable the seesaw lever to move up and down
easier.
2. The holes on the end of the flybar seesaw will need to be
loosened up a bit also. The Flybar should rotate easily in the
flybar seesaw. To loosen up these holes, you do something called
"playing the violin". This involves sliding the flybar
seesaw up and down on the flybar. In a short period of time, the
seesaw will be able to spin easily on the flybar.
Other components
3. The Y-links for the pitch compensator.
4. The Mixer lever that attach to the blade holder.
5. Mechanical Mixer - As it isn't suggested to use this, and
I'm not, I will not get into it. But if you are going to use
the mechnical mixer, take care to ensure that the 90 degree levers
move freely.
Tail
I know this isn't on the head, but since I was discussing
friction, I dumped it here.
6. Tail Pitch lever - should swing freely.
