Minimum servo torque.
#2
Personally speaking I have found that even standard servos with 3-4kgcm of torque can hold a (rubber tyre) touring wheel in position, although you notice the slower speed in some chicanes.
As far as the bellcrank type servo saver, I have had them on a few Yokomos, maybe a couple of other cars too, and they have been strong enough to break servo gears if incorrectly adjusted, so yes I would say they work. To my mind they are a little more precise than the servo horn type because they tend to have a stronger spring.
