How to drive a one-way?
Ok I run sportmans Spec Stock(everyone runs same motor/tires)
Ok So my front diff went out last night at my local club race so I threw in a one-way and was curious on the theory behind how to drive a one-way.
I have had a one way in before and couldn't drive it so I went back to the front diff, even though I know if you can drive a one-way its suppose to be faster. Is that because you can carry more corner speed?
I know a one-way gives you more all around steering, but you loose braking.
So if you rely on braking for off power steering it drives like you actually have lost a ton of steering going into(off-power) corners, its even more noticable in high speed corners like off of a sweeper.
So.. I'm thinking that I need to slow down a little sooner and power through the corners more? I probably should be doing it that way anyways, but how my car was setup I was used to relying on more motor breaking than what I was, This led me to blowing past the sweeper big time, then because I have more steering in the infield I was turning in too soon on the infield.
Am I on base? anybody got any good theories/practices for driving one-way?

Just coming from my first race ever using a one-way instead of diff, I can give you these tips. I feel-even with very little experience that this will help!!
1-car set-up must change. Most likely a front sway bar if you werent running one and up a spring rate. Maybe also a little more rear toe-in if your heavy on the throttle inputs still.
2-driving style must be up a whole nother level on smoothness. MOST importantly approaching turn in and going towards apex. You must roll out of throttle for slow corners a little earlier and not shut off the throttle like a light switch. Roll it off and keep rolling it off as you turn in. No sawing at wheel as well as that upsets the car and heats up the tires (see below).
3-expect to only roll out of throttle to about half throttle!! If your ina long series of corners-unlike a diff and foam tires, you wont be going off throttle, full throttle, off throttle, full throttle!!! YOu may find you rolll back to half throttle and hold it at half through that section and go quicker than "revving" the throttle.
4-If you over drive a one-way car-expect to over heat the rear tires early and expect a loose car the rest of the race.
5-On power its the same deal. Roll it on, especially if your in a long corner. Be patient,the one-way does the work for you carrying momentum into the corner and putting it down as you go out.
Hope this helps!! The guys who race rubber tires and one-ways all the time may disagree, but they dont run a diff 100% of the time either!!!

Brakes-what are those????????
I never got to the braking part, at least not in 19t!! Once a foam tire driver-always a foam tire driver. Though i have seen Blackstock and other pros using brakes in certain corners on carpet.

so what you are saying is you have to be a more controlled driver, which I have heard before, you can see-saw the wheel and have to be smooth with the throttle. I will try that next Sat. thinking about not coming off the throttle too much in the infield and try to keep it at half throttle and above.
Yeah I try not to use brakes as well.. when I said braking in my first post I just meant motor braking by letting off the throttle.

Ray - Thanks a ton!
I'm a novice driver and recently went out with a new car equipped with a one-way and was unable to drive it. I thought it was the set-up but now I see it's really my driving style since I'm used to a front diff. You saved me a lot of chassis adjustment time. I'll put a diff in until my driving skills improve.

A very good set-up is required to!! DOnt get me wrong, but a big change in driving style is critical. I dont thnk you can make a one-way car fast and drive like a foam tire car with a diff. It aint possible!!

This made me think... do they typically run one-ways in Stock foam or put the diff back in when going to foam.

So if you want to be competitive in stock rubber on carpet is a one-way required?

I have limited the brakes from the radio.. that way I can use the brake a bit - and it prevents it from acting like a handbrake..

Use a one-way.. but upgrade to a brushless? LoL..
It just happens that the lack of drag brake on a BL motor is perfect for one-way driving. Not only do you get the super high corner speed of the one-way, but non of the twitchiness off throttle as the motor drag transfers weight to the front wheels...
But in all seriousness... try stiffening the whole car with a one-way. You gain ALOT of steering off power and even more on power.You want to minimise alot of the rear-forward weight transfer, and also any rolling tendencies that you get with the increased steering. Fast one-way setups always seem to corner super flat.. they don't need any chassis roll to hold the corner grip(and speed)
Usual one-way setup including stiffer front springs and an industrial sized roll bar.
If you can adjust the length of your camber links, then try using a short front link. This sacrifices some steering for more a more consistent car. The short link seems to make the whole car more predictable.
Opposite goes for the rear - make the link longer to gain some grip.
Try going for a more aggressive castor block.. This helps with turn-in but mellows out the exit steering. The car turns more smoothly and doesn't "hook" into a corner..
Lastly... use a little more toe in on the rear. Dial it out as you adjust your driving style.
Biggest tip... NEVER let off the throttle completely. Use the dual-rate to dial out some steering..
When i first started driving a one-way i was the same. I let off earlier and let the car roll through the corner with about 1/2 throttle. You soon realise you have a HUGE advantage with mid-corner speed.
Have faith... let off the throttle a touch to slow down and give it more power as you turn. You'll find you should be able to power right through sweepers that previously had you lifting off or feathering the throttle. It's hard to get you head around but apply POWER through the corners...
The more power (gradual of course!) the more the car settles...
