Default Tail (yaw) is way to quick

Hey guys, I just upgraded my walkera 60 to brushless and an alloy head. I installed a new receiver (spektrum 6115e) as well to use my DX8. Everything is set up sweet, I'm fairly new to programming but think I got it right. The throttle curves work and the pitch curves work, the tail on the other hand I am lacking I think. The heli spins so fast with the tiniest amount of stick input. Even with the expo right up and the travel on faily low. Running the gyro on about 60%, I tried higher and lower it made no difference. The bird certainly flys, but not for long as the tail is out of control. The tail servo it a cheap KDS brand off eBay (better than stock though) I've tries different holes on the servo horns as well. How can I tame this thing down. Should I buy a better sevo and if so which one would suit. Or gave I missed something in the transmitters settings???

Just to eliminate the obvious...
Which direction is the tail rotor spinning?
When holding the heli (no throttle) with the pod to your left and tail to the right and you move the tail towards you, which way do the tail blades point?
Have you tried reversing the gyro?

What do you mean which way are they pointing?
As in the areofoil is facing the right direction?
Wagging the tail by hand while spinning gives correct gyro correction.

So is your tail blades turning in right direction. My V450D03 & tarot 450 tail blades turns CCW? Sounds like your belt is twisted so its probably turning CW.

They're turning the right direction, looking over the tail again today, everything seems sloppy and a blade grip seems to be breaking in half. Seems as though when I give yaw input the slider moved and stays there until I give heaps of input the other way to bring it back.
By the looks of it I need to freshen up the back end with some alloy blade grips.

Aside from the faulty parts, sounds like your tail has to be set up properly

Just like John said your tail end needs new parts slop kills I agree rebuild back and setup tail everything should be alright.

I'm using a KDS 800 Gyro with same brand tail servo. Getting the limit set in heading hold, while trying to keep equal movements is proving difficult. Ill order done parts and get back to you guys. Thank both of you John and vronny for you help thus far.

Right guys, completely new tail, so now no slop and servo seems to work without struggling. Went down to the club today, and found the real problem!!! The gyro power plug was upside down on the rx. It was plugged into the negative, derr!! So after swapping it all out, and centering the tail, it flew solid, little wag here and there, but great!
