For our servos we are doing 2:1 gearing, we got the spacing to work out just right. Here's a picture of it. There are 1 pair of servos on each side of the basket. With this method, we managed to get the servos at exactly the same position, for this side 255, and then drop the arm ontop, the servos have little problem with keeping at the same position, and so far we have had no problem w/ torque either.
Sorry for the quality, my camera is MIA so I had to use my webcam on my laptop..
