600 TT Bearing

[Gate88]

How often do you guys change your TT bearings?

Had mine a while now and luckily enough havent had to replace the boom yet. I have had to replace most of the other bearings around the airframe but I am wondering if I should be routinely changing my TT one.

Never replaced one yet mate.

I am lucky, I smash them to bits in crashes.

When it sounds like I need to!!! You can tell by the noise!!

I wouldn't touch a TT bearing unless the heli was making a different noise than normal (high pitched kinda), then I would take it out feel/inspect it along with all the other high rpm tail bearings.
