4WD Setup...Diff Front, One way Rear?

4WD Setup...Diff Front, One way Rear?
4WD Setup...Diff Front, Oneway Rear? Such as in a B44 or other 1/10 scale 4WD car.
How do you think this would do if set up optimally?
Have you heard of anybody trying it?

wow, never heard of a one way in the rear before. I wonder if that would work in a TC with a spool up front. Maybe I'll have to try it.

Here is the theory.
1. During Acceleration (Weight is shifted to the rear): +Peglegging is eliminated because of the oneway in the rear.
2. During Braking (Weight is shifted to the front): +The front differential can transmit the necessary braking power. As an example, a FWD front diff car should be able to brake faster than RWD rear diff car.
3. Left Turn During Acceleration (Weight is shifted to the right rear): +Oneway in rear allows for power to be transmitted to the right rear wheel without peglegging -Oneway forces the left rear wheel to spin at the same speed as the right rear thus increasing the tendency for understeer.
4. Left Turn During Braking (Weight is shifted to the right front): +Diff in the front will enable differentiation and braking at the same time. This will allow for powerful braking and being able to tune for neutral steering.

The problem is that with all that front brake with no rear braking the car will not turn while braking. If you don't drive that way it might work.
#6
I guess from a theoretics point of view we could have long discussions...I just need to buy a B44 and try it out! haha
Does anybody have any real experience with this kind of set up?

b44
You might have a hard time trying that in a b44 since it is shaft drive and you would have to flip the diff over so the wheels would be going in the right direction. I believe that you would have no rear wheel drive and 4-wheel braking. In a belt drive car it shouldn't be much of a problem though.

If you drop a front one-way in a B44 rear you have made a FWD with all wheel brake's.
Other way is switching the one-way bearing in the housing,
then you have a one-way in the rear like it works in the front.
Without any rear wheel braking i think a RC car cant be drivin like it should at all.
But i would want too see a video if you go and do this.

You guys ever try running a solid front?
The benefits of an oneway + braking as well, been thinking of trying it to see how the handling would get affected.

The problem with spools is that they do not allow differentiation for the turns. Both one ways and differentials allow for left right speed differentiation.

Now the downfall i see with a one-way in the rear and this is my theory on it is when you brake for a corner the front wheels are slowing down via the driveshaft or belt but the rear wheels are not thus the car is going to get rear end loose easily coming into a corner and if you are braking while turning i will bet that the car will want to spin out very easily.

thats what i meant.
#15
I believe that a spool in the front will take away some steering verses a oneway. Don't they use them quite a bit in onroad.
