Rubber O rings on centre shaft?

[gramey]

???Sorry to show my ignorance peeps but what do the 3 red rubber O rings at the front end of the main drive shaft do exactly? It says that they adjust the braking but do you move them back the tighter the track or leave all 3 on the black plastic shroud/cup?

By putting an O-Ring or more on the black plastic part it applies more pressure on the steel oneway coupling. If you run with no o-rings the oneway will be as free as it can get and this will allow more steering in the corners allowing the front wheels to freewheel like a 2wd buggy(only applies to off power steering, you will still have 4wd on power). Now if you put an o-ring on the plastic coupling it will put more pressure on it to lessen the free wheeling action of the front wheels, taking away some off power steering. The more o-rings you put on the more pressure is applied and the less the front wheels will want to freewheel when off power. It is give and take, by having less or no o-rings the car will have more off power steering but less braking due to the fact that only the rear wheels will be doing the braking and the front wheels will freewheel. By putting o-rings on it will have more resistance to freewheel which will allow the front wheels to help slow the car down more, hence more braking with more o-rings. More o-rings/morebraking makes the car more forgivable but will have less off power steering. if you have a tight track with tight turns no o-rings will help you steer through the corners better, if you have an open track with high speed sweeping corners you might be better off with multiple o-rings. Try it with and without and you will be able to tell the difference!
