Default Looking for Vcontrol/Vbar setup values Comet

Has anyone posted values for the Mini Comet? I have Vcontrol Tx and Neo.
First flight was big grins but a little tail wag, no biggie. Didn't roll or pitch very quickly. Second flight played with reduced tail rotor gains but it didn't really reduce the wag. The tail just got sloppy. Raised the cyclic value from 70 to 80 to speed up cyclic but every time I did a loop in any head speed (I have 3600/4200/4800) about half way around the heli started shaking like a leaf, looked like all three axes (axis?). I came in and redid the cyclic and pitch setup. +-95 gives +-13 degrees pitch but I have to go down to 65 to get an honest 8 degrees cyclic. Thats not in the suggested range of 80 or higher but I'll see how it flies tomorrow.
Overall i really like it. It is easy to see like the 380 and flies smoothly "like a bigger heli" looking forward to getting it dialed and see how fast it goes

I'm getting closer to being able to list my own settings as a suggestion but I have two major reasons not too. One is that as well as it flies the tail still wags a git from time to time. I'm not sure Vbar tweaks will ever stop this, and I don't mind so much, if I just ignore it and fly it is not a problem. Also at 4800 rpm it will bog if full collective is applied, it seems to be a little too much to ask this competition power system to maintain 4800 rpm at 13 degrees pitch. Why SAB specifies 15 degrees and 5000 rpm for fast flying is beyond me, unless I have not got my setup dialed just right.
But FWIW i really like this little heli, it flies surprisingly well considering it's weight and it's fast too

Numbers will be different for each heli.
Glad itís working for ya but the tail wag never goes away for some people.
Well, I made it go away, I sold it.

Agreed. Plus with little helis it's hard to get them perfect. Anyway, it is fun to fly and looks great in the air.

I just got my havok 280 up and running. I can say that tail gain has to be very low. 3500/4500/5500 with gains of 40/35/25 or else I get massive tail shakes.

I'm really looking forward to seeing your settings, I have a mini comet on the way however it has a kbar fbl on it, all new to me . I still use the original BX7200 on my blade 300x.
