One of the gents at our field had a rather strange problem last week --
a weak servo. He replaced it with a new S-3001.
Today he brought his model back with the same problem. He is using two
aileron servos connected via a "Y" harness for his ailerons. They both
operate properly, but when the ailerons are held in full throw in either
direction, you can very easily push the left aileron back to neutral; when
released, it returns to its commanded position. This is the bad side. The
right side cannot be pushed out of its commanded position easily. In other
words, the left servo appears to have no power.
While at the field, he reversed the leads within the "Y", but the
problem remained on the left aileron, thus eliminating the harness. Since he
had already replaced the servo, the only logical fault could be a defective
servo extension lead that's not allowing full voltage to get to the servo.
He couldn't check this at the field.
Do any of you have any other possible reasons for the wimpy servo?

Or another bad servo. Had something similiar happen to me a couple
times after ruling out what I had just replaced. Turned out the new
one was also defective.

I've also had two "bummers" in a row. Strange, but true.

Bad batches often end up next to each other on the LHS shelves...

Yes. My thoughts too.

I agree with the consensus of opnion...I'd give you
odds that the servo is defective.

I had EXACTLY this one a brand new HS55...I worked it up and down a few
times and it seems to have sorted it.. No servo extender involved at all.
But if this sort of messing about does not appeal, simply replace the
servo and send it back.
