I've had a problem w/ a tail boom vibration for about 2 months now and no matter what I did, the vibration never went away. I went over the entire ship, balanced everything and still the horizontal fin was buzzing over 1700rpm until today, When I went to Toledo, one of the reps at the XL booth sold me a shorter pair of tail blades (SAB 95's) and that did the trick. What I want to know is how going from 105's to 95's makes such a big difference.

Happened to me too.

On my xcell 60, I switched from these heavy old black tail blades the Xcells used to have, to a set of fury tail blades that came off of my fury kit. The fury tail blades weighed about 1/2 the black set. My tail buzzing got so bad with the black tail blades that the boom would twist around in flight.

Now I get better piro rates and no tail buzzing with the fury tail blades

Your 105mms could have been out of balance. Did you balance the blades and hub assembly? Did you try these pair on anther machine to see if the vibration followed?

The 105's will give you better control over the tail than the 95s. I moved to 105s to give me better holding power in sideways flight and other pirouetting maneuvers.

I found the extreme tail 'extremely' sensitive to engine tuning.... just slightly too rich and the tail would twitch away like mad!

Could it be this
