anyway to tighten centerpoint on a hs55 servo?

[jeff262]

I was just curious if there is a way to tighten up the conterpoint on my HS 55 servo? when i move the servo it has lots of slop in its centering. it will still try and bring it back but if there is resistance from the control lines it will just hum around 5 degress from center. its like it cuts down the power when centering and just can't bring it back to full center, its like this on 3 different hs55. but moving the servo with the stick there is plenty of power to move the servo to center. any thought would be great
thanks jeff

HS55 servos are generally tested as good values ...

under a 2 pounds x cm load ( max reasonnably allowed for this servo... ) neutral error was measured to be 2.5 degrees.

Do you really use the servo for what it is intended to bear ??? That's the main question ...
take 2/3 of the 4.8v load given by Hitec ... that's the true max usable load !!!

one of the usual casualties of specing 6 volt performance on a 4.8 volt servo is the increased deadband (and/or minimum pulse) required at 6 volts to compensate the feedback loop for the increaed motor speed.... run it at 6 volts, or get a data sheet for the servo chip if available and reduce the deadband (and/or minimum pulse)....

:cool:
