Part 1
I have not wacked the tail on my Blade (yet) and there is the slightest of vibration noticeable in the horizontal fin. Seems to be slightly worse with new and balanced CF blades. I know that others have been trouble shooting to eliminate the vibration but I am wondering if a slight vibration is normal. Grips have the same play on my bird. It flies great, so I doubt I will change anything until required.

Part 2
Also curious to know .... when you give the main rotor a bit of a spin by hand, can you hear a slight "swish noise " in the tail rotor? (I am assuming I am hearing the belt going around the tail drive pulley system.

The swish noise on my heli comes from the idler pulley on the tail.

Regarding the vibration, man it could be a number of things. Mine happened to be the grips yours could be a worn bearing or whatever. These little helis need a lot of TLC.
