REVIEW - of "The Greaser"

[pinguin]

How often do you have to grease a bearing? 50, 100, 150 flights?

So every certain flights I have to disassembled the heli and put the grease on the bearings? I'm not comfortable doing this. I'm afraid on disassembling a perfect flying heli, because when put it back I might miss something that cause problem to it, such as: vibration, different flying characteristic, etc.

I just replace my main shaft bearing on T500 an notice that the old one is pack with lube. What about a smaller size bearing, does it come prelube from the factory? How do I know that the bearing already lube from the factory.
