Can you give me more details? I am not sure what to do based on your description.
if you take the servo appart, like in those pics in the web links above, the pentomitor is busted (they are silver and gold in the web link but the futaba one is black), im guessing it needs to be replaced and heres why.
if its resisting your hand pushing on it that means your motor is fine, im guessing the other electronics are fine as well cause the motor wouldnt resist you. the pot is what causes the movement so to speak, when the servo gets a signal from the rx to move full right, the pentomitor no longer matches what the servo wants, so it signals the motor right or left, as the motor gets closer and closer to full right the pentomitor (now that it has moved to the right cause its linked w/ the servo gears) slows the motor to a stop and the servo stays at full right till you give it another command.
if the pentomitor is bad it may not be sending the command for the servo to move
im just guessing and wouldnt be surprised if im wrong about this, but if this was my servo that would be the first thing i replaced.
That is spelled: potentiometer A form of variable resistor with a movable ''tap''.
sorry i cant spell, i use pot most of the time but i didnt think he was understanding what i was saying
