One-way or Diff
 

This year was my first one racing with a 4wd car (I previously raced 2wd for 8 years), and I have a problem.

I don't know when I must mount the one-way or the ball diff at front.

Can you help me?

Thanks a lot.

Not really a question of "must", more how it feels to you, and how the laptimes are.

Very basically, the one-way will give more steering. Downside is a loss of stability if the grip is low. Also, the front one-way gets put under a lot of strain on very bumpy tracks or if you clip the markings, whereas the diff is much more forgiving mechanically.

Don't forget that the ZX-5 has a centre one-way option too.

From my experience the car runs a lot better with the centre one-way than with the centre locked. I've only run the diff up front.

Some people like the front one-way, so why not give it a try!

Don't forget with a one way diff you only have the rear braking, whereas a normal diff would give 4wd braking.

Excuse my english... I whould said "should", or not? I feel that the car is more stable with front ball diff in bumpy tracks, and more steering with the one-way in high grip tracks, but I want to know why. I think it could be to have rear brake o full brake..perhaps?

What is the diference between mounting centre one-way or centre locked? (I didn't tryed this setup)

Excuse me my stupid questions, but the zx-5's manual does not explain anythings (like Losi's manual), and this is my first year in 4wd.

Thank you!!!

I fully agree at this point. Good instructions for setup and using option parts are only found from other manufacturers.

I tried the one-way front and center but switched to front diff and locked center again. The car is easier to drive for me with this setup.
Using one-way I had problems with the break.

I am a complete beginner (last time I drove RC cars is 20 years ago) and so I gave several setups a try. In my opinion that is the best way to find out how the car reacts when changing something.

where in the manual does it explain how to put the one way in the center? i cant seem to find it.

do you need to buy extra parts not already included in the kit?

The manual is very poor when compared to some out there now, i had the same problem, but you should have one of these with your kit that directly replaces the oneway unit.

And these for the oneway set up

All right, I have tryed centre one-way and centre locked.

With one-way in the centre, the car nose up over jumps. Without brake on the front the car is unstable in bumpy tracks. Afterwards I tryed centre locked, and the car is stable and jumps better.

Then, I will try one-way feature in the future in high grip tracks.

Thanks a lot.

(Excuse me my english again)

Those are the parts for Step 21 on page 17 ?
In Step 21, there are two diagrams, the left one is "For differential specifications" and the right one is "For front one-way specification".

So you meant the left diagram > centre one-way
the right diagram > centre locked ?

yes, that's right.

i only ever run with a centre one-way and front diff. The front one-way diff was too aggressive.
