Century Hawk Sport -- REVIEW -- Opening the kit!!

YS 61 STii

I'm running a YS 61 STii Heli. I have two questions.

1) How do I know when it's time to change bearings?

2) Do I have to re-break in engine after changing a piston ring and liner?

Thanks.

shaky climb

I'm pretty sure about the truness of the feather shaft and main shaft. Shaking means that its tail is moving left and right - oscillating while it is climbing. Thanks.

shaky climb

I have no idea about the head speed since I didn't tach it. The pitch is low:-2 mid:5 high:9. The engine generated higer note than during a hover. Thanks.
