I just put the Dynam Vortex Flybar, with adjustable weights, on my CX2. First thing I noticed was the difference in sound. It seems to be deeper, and not more quiet, as I expected. It has more of a thumping sound. Sometimes it makes a deep, louder thumping noise. I can't seem to determine if it is happening as the result of a particular control input. I might hear it more on liftoff or when gaining altitude. The blades don't track as perfectly as the stock flybar and I can't get it to perfect by adjusting the linkage. Mine is screwed in almost all the way as compared to the stock flybar which had 5-8 threads between the two halves (linkages). There is no TBE the way I have it now.

I've also noticed a new glitch, of sorts, where the heli makes a clicking sound, very faint, and it drops about a half inch almost like it has lost power for a fraction of a second.

I also think my flight times have dropped about two minutes from my previous full charges. I have two different batteries and they both show this loss in flight time. (MegaPower & E-Flight)

I just wanted to throw this experience out there and see what you thought. Does anyone have the DV flybar and does any of this make sense? Can these new problems be attributed to the new flybar. Does yours sound like what I've described?

Additional info: The new flybar definately improved handling and continuous foward flight. Also seemed to reduce the bouncing around after an aggressive maneuver.
I have the Boomtown CF tail and also cut the front third of the tail section to fit over the boom and o-ring. I think it looks great and will post a picture soon. Sorry, I like those little side wings even though it diminishes some of what is gained by putting on the CF tail boom.

Thanks
