Good info, Devryn...Those resistors are easy to wire into the servo wires. Those things that you need to solder on the board are too damn small. You would have to have excellent soldering skills for that.

Thanks again.

No problem. I got the fix from another board, so I can't take any credit.

Warning though, there are alot of newbs there, and they can get really really annoying.

Where did you get this info? I have a 180 motor in my Mustang with the inline resistors, and it works fine.

Oh, I'm not saying they won't work, just saying the ones I got were quite big and there was no way the ones I had were going to fit with the 180. I'm going to use the 3.3K ohm SMDs inline with the servo pot. At least it will put those to use.

Anyone know offhand if Fry's or comparable stores sell 472 SMD resistors? I guess I could always order the kit from AtomicMods, but I was doing some XMODS errands tomorrow anyway so I figured if I could pick them up somewhere to go ahead and get a bunch of those, too.

Figured "to hell with it" and ordered the AtomicMods resistors. There are 3 to a pack, and I got 2, so really, I can do 3 ESCs. I practiced soldering some spares of the same size (about 1.25mm by .75mm...REAL small), and it went remarkably well, getting a very tiny but complete dab of solder on each side. The trick was to tape half of it down to solder one side, then do the other once it's secured. Took a split second dab with the iron tip set at ~280 degrees C. Actually was harder getting the originals off than putting the new ones on.

hey guys i just want to post again that i have the 2.7k resistors. i'm selling them for $2 shipped for 2 resistors. you can e-mail me or hit me up on aim.

Put the surface mount version of tight turns into my car. Damn, what a difference! That almost doubled the steering range.
It actually wound up being much easier than I expected. I cranked up my soldering iron to 290 degrees Celsius. I then lightly pressed the tip against an edge of the existing resistor. It comes off in a half second or so. Next, I get some thin masking tape (scotch is too rigid), cover half the new resistor, and secure it to the board. Next, I got some RS silver-bearing solder (.015" diameter, 62/36/2), lowered the temp down to 270 degrees or even less. Put the tip on the pad in front, touch the solder on it and push in a touch of it and take both off. The actual act of soldering is literally done in a moment. Do that 4 times, and you're done. I also got my newly designed wire layout in there, using very minimalize wiring that I prebent, so my ESC is officially done pending a final range check. For those intimidated by surface mount board work, it's actually much easier than I expected it to be.

Sounds like to need to re-center your servo. The easiest way is to adjust it via the controller, but there is a way to take apart the servo to center it permanently.
