Screeching sound when rudder

[genexis]

Hello, I have this problem when i remove my blades, leaving the flybar and the padding. Then holding the heli firm, I throttle up. When i rudder in one direction, there is a screeching sound coming from the body of the heli (no idea exactly from where). Whereas when rudder in the other direction, no such sound is heard.

The screeching sound is like when a real car drifts.

Anybody has any idea why ?

Possibly it's the bearing at the rudder belt..
There is a bearing to keep the belt running properly at the top of
the casing of the tail..

Drop a few drops of lubricating oil to remove the screeching..
that's wat happened to me and wat i did!

Hm, how come it will happen only when i rudder to one of the sides ? But i don't think it is the bearing, cause the noise distinctly comes from the center, near the gears/motor/gryo area.

hmm.. okay, if it's from the front then it's probably one of the
bearings in the front..

check your one-way bearing, it may be slipping

Nope, not the one way.
