But with a little it luck it will be barely visible once the salon is done:

This servo (Hitec HS81, approx 1 kg/cm) apparently was not strong enough, it caved in a few weeks ago. Dead as a doornail.
Replaced it for a slightly larger, but 3 times stronger servo, Robbe RovoR FS 0270 MG BB, that is claimed to pull 3 kg, ballraced and metal gears...

That should do it...
EDIT: apparently, that old Hitec allready spent quite a while dying... A short test in the bathtub showed a HUGE improvement in precision and fine-control.
