BEST smooth servo for GoPro gimbals?

Hi guys

Can you share your experience about best SMOOOTH rotating micro servos?

I'm testing my gimbal, but I'm not 100% happy with TowerPro servos.
They are working, but not as smooth as I need...

I can pay more, but I need warranty that servos will working smooth,
much better than TowerPro. Can you recomend any?

I have been playing with some one another mount here, the best results I have had are from the HG55. I have found that metal gear servo's tend to be a bit notchy when compare against the direct nylon geared equivilent.

Also helps is you can use a bit of gearing instead of a one to one ratio, so you have more servo movement for a given camera tilt movement.

a geared setup would be smoother as well

In this mount axis are reduced <> 1:1.5 (pitch) and 1:2 (roll).
Source of small vibrations are in servo I think.

I just back from local RC store - I have just bought pairs of servos:
TowerPro SG91R, Hitec HS-55, KDS 9g and I have one Hitec HS-65HB
and EMAX ES08MD.
Tomorrow I'll make some comparision with different pairs of gyros...

Any update on your findings? I'm using a direct HS55 and find the result very jittery:

No. Still EMAX is the best. Unfortunately not popular...

I'm thinking about my own servo production but this is madness...

We need fast, high resolution, jitter free, and smooth servos
Most servos are fast, low resolution, full of jitter, and not smooth.
