RE: Futaba Servos
Not to get into the question at hand,but I have a issue that has been plaguing me lately; I have had to swap-out 3 of my 3004 servos in 2 planes because they "float". By that, I mean if I run the servo(s) in one direction, and let them go back to neutral, they tend to overrun neutral by a little, then neutralize. There is another fellow pilot who experiences the same condition.
Is this humidity related? Or something deeper. I have, at times been able to take the servo case apart, expose it to low to mid range humidity\temperature, them put it back together, and it's fine.

RE: Futaba Servos
I have seen that happen for a few reasons.
One was from using a long cheap (hobbico) servo extension. I replaced them with the heavy duty JR's and the problem went away.
Sometimes the connectors get corrosion or moisture on them, and this will cause it.
The other time it was just a worn out servo. (I would guess the centering pot was shot)
I would try unplugging the servo wires and cleaning them first. Then try some different extensions (if the servo is on one!) and see if it clears up. If neither of those work, I would switch the servo out.
Good luck.
