:ö: Arch,
if you are going to use the adjustable resistor or what they call "trimmer" ¤ DON'T REMOVE THAT RESISTOR ON YOUR SERVO CIRCUIT BOARD!!!
¤ , just install it (trimmer) as if the resistor wasn't there, i've tried to removed that before and i can't find the 0 point, just attached one feet of your "5k ohm trimmer" on that resistor then turn the dial on the trimmer, notice that the speed of the motor decreases? if not, try to re-arrange the position of your soldered trimmer feet ti'll you notice that the motor reacts to your dial, one of the outer feet of your trimmer should be soldered on the resistor that is installed on your servo's electronic board..,. move the dial 'till the motor stops spinning, that's the 0 point, (do this while the motor is not yet installed on the truck)... now if you are going to use a "normal resistor" like the one on the thread i've posted on

this is much easier to install just follow the last instruction properly, and there you can remove that resistor sticking from your servo circuit board, because instead of attaching another 2.2K ohm resistor on the 2.2K ohm resistor of your servo board, replace it with 5.4 k ohm which is also the same value (almost) of 2x 2.2K ohm resistor in series connection
, i'll post a pic of the modification i made on my PICO servo 5.4 grams electronic board.
and here are the good points using a normal resistor than the trimmer,
1. you'll do the trimming on your radio (throttle trimmer) rather than twisting the dial installed inside your truck everytime you turn it on.
2. just solder the resistors as instructed (which i find very simple
) and it's automatically on the 0 point!.
3.you don't have to twist or likely to damage any "dial" on your truck, cause there is none!
4.resitors are "smaller" in size compared with the smallest mulit-turn trimmer you can find.
hope this help
