The difference is the FET wire and 0,08 sec. versus 0,06 sec. / 60 deg.

You dont need a ESC with a FET wire. The included manual shows how to do it.

Will 0,02 sec. make a difference? I dont know, but personally, I took the 2123, just to be sure.

2143 vs 2123 sv S9550

Get the 2143, It's fast enough and takes a beating. If you need space then the S9550 is okay, you do feel the diff between the .08 and .11. I coulnd't feel much diff between the .06 and .08 of the 2143 and 2123. So to me the 2143 was the sweet spot (and I got it used for $60 which made it sweeter)

I don't know, I just got a KO 2123 for my XXXS, and tested it out today. The performance of that servo was incredible, like Cole said, the ability to change direction in the middle of a chicane in the blink of an eye was awesome. I also love the resolution, it's so precise and centers perfectly every time. Also, wouldn't a servo with a coreless motor last longer than a non-coreless servo? (Or would that even matter)

One thing I really like about the KO 2123, is the FET wire.

Most power supplys, got a build in safety circuit. Because they dont like too large currents. So if the current gets too high, they simply shut down to protect them self.

Even though many high end ESC got BEC's with 6 volt / 3 amps, they probably got a similar self protecting device. So if a servo in the peak exceeds 3 amps, they dont get it. This gets even worse, if the BEC is a cheaper one.

By nature, this cannot occur with the FET wire.

ok thanks for all the replies....i just bought a KO2143 and it's really smooth when moved by hand compared to my Airtronics digital servo...by the way would coating the metal gears with Tamiya Anti Wear Grease be a good idea??

It might void the warranty.

Ian ,

I had read from somewhere that we must careful about the type of grease to use with the servo gears.The reason is that some type of grease will vaporized when it's hot and its vapor may cause problem with motor brushes.

I'm convinced that you already got a high end servo - if anything can be done to improve it, KO already have done it for you.

No No No...if you have ever used the anti wear grease you will understand. The original servo comes with plenty of grease. If you need to do a rebuild then use Tamiya ceramic grease.
