ZX-6 Wish List

[Chris119]

After purchasing the ZX-5 FS2 SP coming from a Durango 410 I must say I love this car. I cant help but think with the RB6 coming out that a ZX-6 is in the works. What would you guys like to see changed on the new car? For me the performance is awesome. I would like to see the bulkheads, and steering linkage in aluminum with Carbon fiber towers.(I have raced twice and broke rear bulkhead both times) For the price these cars should have more strength in key areas and a little bling wouldn't hurt.
Your thoughts?

[InsideLineModels]

When you say rear bulkheads what part do you actually mean? Do you mean the shock tower mount?

[tomtom]

I think he was talking about links plate.

[Chris119]

Yes sorry, the shock tower mount.

The tricks to building a really strong Lazer (I wish somebody would sticky this, type it a lot!!)

Firstly DON'T OVERTIGHTEN ANYTHING, JUST NIP IT UP!! Sorry if that sounds aggressive but I see so many people bottoming out screws then putting a load of extra compression into the joints, this stresses the plastic and WILL lead to a failure eventually.

1) replace the bolts that bolt through the tower mount, link plate and trans case with 18mm - 20mm long cap head ones (depending how high you space your tower up, I use 20mm as I have the front +1.5 & the rear +1.75). Put a thin plastic spacer under the heads of these, I use the ones from the shock sprue, same as I use to space up the tower. I prefer cap heads as they are much harder to round off.

2) places a small plastic spacer under the head of the single screw that goes the tower mount into the center of the trans case, make sure that the screw is long enough to just break out into the inside of the trans case but not long enough to touch the diff.

3) Fit the tower to the tower mount using slightly longer screws, not so long as to come all the way through the closed hole on the tower mount, that weakens it.

4) Do not use carbon towers or ali tower mounts, they transfer the loading to the trans case and that takes much longer to change if you break it.

5) Use bolts that are only just long enough to mount the shocks so that no thread pokes through the back of the nylock nut and fit the shocks like this ...

screw- shock bush - any spacers - plain nut - tower - washer - nylock.

This is totally opposite to how most cars build instructions tell you to do it but it does 3 things for you;

a) means that the loaded part of the bolt is longer so it will bend before leavering a failure on the tower
b) means your much less likely to crush the top shock bush by accident and end up with a tight upper pivot
c) means that you only have to undo 1 nylock per side to move the upper shock position (I play with this a lot)

Point 5 is particularly important on the front!!!


Follow this & you will be near bullet proof

Good advice Rodger.
Though I find it hard to belive people are breaking this car? Or questioning the strength of it.
I'm on my 2nd ZX5 the SP2 kit & have to say for 2 & a half years all I've broken is a front wish bone & a top shock mount. This has to be one of the toughest cars On the market today.
God only knows how some people would go on with some of the competition! & I've run every thing including Durango's, 511's, schumacher's, Pred's & so on.
I think the Lazer has to be one of the toughest out there.

[RogerM]

I agree, I have no idea how the breakages occur but my suggestions seem to prevent them.

Still have a friend who seems to suffer. I've not broken anything on my cars in competition this year, ok some crazy hard pushing has resulted in a break or two in test sessions but seriously, most other cars would have gone home in a hoover when the Lazer usually needs no more that a few screws turning to be back on track in a few minutes.

[RogerM]

Going back to a ZX6 wishlist though here is mine;

1) vertically split transmission cases so you can get the diffs out quicker (I'm lazy)
2) stiffer / carbon top-decks (personal preference)
3) slightly lower ball stud position at the rear (personal preference)
4) slight revision to the steering rack as now I've built an RB6 all other racks feel poor in comparison

That is it ...

[JustARcFan]

Any hints when the ZX6 is going to be released?

[tomtom]

Not until the worlds from what I've been told

[JustARcFan]

And when is this?

[tomtom]

Mid July

[JustARcFan]

That's a looooong time.

I need a winter project!

Nothing wrong with the zx5-fs2-sp
