Why would you want one over the other?
Advantages/disadvantages....not even sure what they do.

Same here , I know the theory of center one-way , front one-way and spool.
However, just dun really know when to choose between them. Their advantages and disadvantages.. I know heard that if I use front one-way on a long straight and need to brake hard for a u-turn, the car will tend to lossy when breaking.. but front one-way will capable for better and smaller turn.

Anyway, I do want to know the answer too. Thanks

In short, use a spool for technical tracks and a 1 way on flowing tracks.

A spool locks the front wheels (no diff action/feeling) and gives good power on steering to get out corners quicker.

The 1 way does the opposite, and lets the front wheels disengage drive when off the throttle. this helps the car flow through the corners faster with less drivetrain resistance

Adding to that, a centre one way has the same effect as one on the front axle, but it wont feel quite as noticeable due to drivetrain drag. You still wont have much braking action though, *so be careful* when getting past people or working out your optimum line through the twistys

what if you one way is too lose? what will happen

Spools are easier to drive and you can brake hard with them. Spools have pretty much taken over on asphalt no maktter the track lay out. The only place people run one ways is on carpet but even on carpet guys are running spool more and more often.

The braking is a big deal as you can run under and out brake drivers running on ways all the time.

+1, I see ya there!

One ways do suit some tracks, but they have to be very open and flowing and if someone else is on a spool, you need to watch your back....

Take a look at pages 34-36 of the XRAY NT1 Set-up Book .

Thats correct for foam nitro cars but the redcution in off power steering and decrease in efficency just dosent happen to rubber electric sedans in reality.

We (I mean all sedan teams) have 6 years of spool setups under out belts and every sedan can be setup to turn in HARD with a spool.

As far as efficiency I have never seen a mod sedan have any more run time issues with or without a spool.

With a 19T or stock sedan it really is not an issue.

Also, every major Stock, 19T and Mod Asphalt race in the US since 2001 has been won with a spool. Even ar ROAR Nats where one ways were legal to use.

When experimenting with setups and running time attacks on a small 9 second course, I found that I clocked pretty good times with a one-way. With a spool setup, I can usually clock faster laps, but with less consistency than with a one-way. For that small course, I guess it's pretty much even in terms of lap times.

When other cars are put into the equation, though, I tend to do much better with a spool. Retaining the use of brakes really helps when unpredictable situations represent themselves in a race.

wow, that really is a big statement for spools, owned!

With a spool I feel that the car is more predictable and direct. It does not wonder as much compares to one-ways. You have more control.

I will be testing the difference in lap times between the two this weekend.
Will report it here if it interests anyone.

A little details are as follows;

Asphalt / TA05MS / GTB / Orion 10.5R.
