So in my infinite genius, I managed to fry my little servo. It involved some re-wrining, large amounts of "how much harm could I do" stupidity on my part... and it's dead.

I'm looking for advice on a replacement. I ordered the cheapest little servo I could find (thinking it doesn't work too hard so it should be OK)... and I'm amazed at the difference. The replacement has trouble deciding on what position it should be in unless the wire between it and the Polarshield is quite short. It's going back.

I was really surprised that there was such a difference in the abilities of the controller boards in the servos. It it normal for them to be that sensitive to the length of their control wire (3-6' in my case), or is it just because I ordered the cheapest one I could find?

Thanks for any tips. Luckily I only killed the servo. I was wondering how long it would take me to do something like this.

When I first needed to buy more than just one or two at a time, I thought, "surely all servos are more-or-less the same" and got a few different ones from a few different places. And was confused by how some appeared faulty right off the bat, some only moved half the distance, some seemed to have massive backlash problems. Mind they were all the extra-micro-sized ones.

The ones I use (http://www.oomlout.co.uk/servo-micro-p-195.html?zenid=936b8ed00e6a2cf736e46e7ab842bddd) seem to be reasonably reliable - only one has ever died without prompting, but I do make sure to test them now, because probably one out of five or six has a reduced range. So instead of going 90 degrees it goes 80. I assume it's because the potentiometers in them are subject to the same kind of quality control that other pots are, like they're only guaranteed to be accurate to 5% or somesuch. The range can easily be adjusted in the code too, if needs be.
