Error In 550 Carbon Manual
Spotted a mistake, well if not a mistake then something missing atleast.

On the head build the swift has 2 holes cut in the main rotor hub. Just above of where the jesus bolt connects the main shaft to the rotor hub. These two holes have threads cut in them, but it does not say in the manual anywhere to put any bolts in them. But in the detailed real picture in the manual it shows it with some in.

I will post a pic soon.

That head block is much like the one used on their 50 sized nitro/glow Raven and their big 90 nitro/glow and gasser Predator helis.

Those threaded holes are for M3 bolts, to squeeze the lower part of the rotor hub against the mainshaft. This will prevent any type of "hub rocking" to ever develop in the lower end of the hub from extreme 3D maneuvers.

Yes, as you said or as the club member who spotted it said it prevents rocking in the head and wont wear out as fast.

But bottom line is, it isnt in the manual

As I had past experience with that type of head, I had not even noticed the omission in the manual. I trust they will be correcting the ommission in the next printing of the manual or adding an addendum as is their usual practice if something is missed in the initial publication of any of their manuals.
