You have 2 and 4 degree caster blocks.

Hi Robert,

As most of the guys have said on here, a one-way will probably be quicker outdoors. However, you should note that it can be trickier to drive, as you basically loose the ability to brake hard. With a 540 silver can though, it should be good to help keep your corner speed up (it gives a lot of front end as the front wheels are free to run at their own speeds off power), but if you start going towards the brushless motors of 17.5 and lower, consider the spool to allow you to use the brakes.

Any more questions, ask away, glad your finding the setups useful.. knew there was a reason I kept them up there

HiH
Ed

For our super tight parking lot racing, most people found the front diff to better than both the one-way and spool. When I drove my MSX w/ the one-way it was very fast, but I was very limited to only one line. This means you cannot be agressive and defend corners to keep them from over taking. Essesntially they could easily cut inside and bump you out as you turn in. After switching to the front diff, I was able to defend position much better.

Spool wouldn't cut it w/ our tight 180's (understeer city)...

Yeah i was a good thing you did. from what i can gather i am going to have to setup my car as far as toe, camper and caster and then just play with the diff till i find what works.

+1 with Tryhard's answer.

You do have to be very smooth with your throttle and brakes to use a one way properly, or a one way can work against you.

Think of it this way. all the time the car is accelerating and braking there is more chance of getting that level of speed or braking wrong.

With a one way, the throttle should be quite gradual (not like an on off switch). this equates to carrying more speed through a corner, and a more balanced and smoother throttle.

However. With a 540, you are not racing with lots of power or an insane amount of speed, so you need to keep the speed you have kept up through corners, hence using the one way can help that.

Just be careful of your braking zones and other cars around you....

Your racing lines can also change to use the speed more, which may involve taking a wider line than usual.

Some tracks can be high bite, taking too much speed through a corner may result in grip roll, but with a 540, again, this shouldn't be a problem, but one thing to have in the back of your mind that should it happen.

Should it happen, firstly, look at gluing the sidewalls of your tyres, or secondly, look into your car setup a bit more.

Sounds like Tryhard has this thread covered, but if im around i'll try to add some answers if need be

No problem, glad to help...

Don't always rely on a team driver setup to help you go fast. "One mans meat is another mans poison" so the phrase goes.

Use it as a base setup (like the one that comes with the kit) and make one change at a time to see if it suits you.

If you then go on to try different things on the setup and it still isnt to your liking, then go back to kit settings and try stuff out from there, it's all about learning...

Good luck
