Yes, you glue the pots into place, remove the stop, and drill the output gear a little larger so it can rotate.

Does the servo jitter when you take all the gears out?

Have a close look at the gears, are any stripped?

Yes the resistor method works and there is no chance that the central position can move my more than 1 click on the trim. I know this works for the SD200 servo but had a little trouble with the micro 9 servo so you do this at your own risk!
There are 3 wires into the pot. I replaced the pot with two 2k2 resistors one from each side to the middle.
(NOTE: some servos do not have the pot in the middle when in the central ouput position. The safest way to test the pot would be to use a multimeter to measure the resistances and find the closest possible match)
I have now moved to motors in my ants using dula motor control boards such as the SOZBOTS board, there is never any twiching.

I find a 2.2k and a 2.7k together work best.

how do you guys get the most grip out of your wheels mine frequantly slip and slide?

Until just recently i had elastic bands for grip now i am experimenting in mouse mat foam.

What do you suggest i try?

Dycem comfort is good, but needs frequent replacing. I've heard lint roller is good, but can't find it anywhere.

Failing that, elastic bands are ok. I once even used insoles from my trainers. :D
