Lazer zxr

[BORMAC]

Just a quick question for those of you who might know, I am driving a modded ZX and have the wider stance up front with the LA-59 'C-Hubs. I have broken one and have thoughts to investigate if there is an alloy version of this revised part. Also are the TEAMLINE hubs standard with the wider stance and increased caster angle?
Any help would be greatly appreciated. Thanks- Jason

[Welshy40]

Teamline are identical in every way but are much stronger and ball raced. I used the wider front with those teamline hubs. Yes they did a 5.0 and a 7.5 version (which is .5 more than standard 7) but thats for major grip such as carpet.

[BORMAC]

Thank you Welshy. I don't suppose you know of any of these wider Teamline hubs around for sale (or trade) do you? I would really like to race my Lazer this year and have been told how great these items are.
Cheers-Jason

I believe Rondoola has some.
I've dyed one set black and another a darker blue but can't remember how many more sets I have, I've started doing a bit of a cleanout here things have gotten out of control

[Welshy40]

Yup my buddy Rondola is a good starting point.

Many thanks Welshy. I have sent him a PM.

As per Mr Pargu I am shocked to hear there are some troubles with him. Ok, so I know his delivery times vary greatly but I recently had a special request and he met it and didn't even charge me shipping. I've always received my orders (in the end) and I really like the stuff he sells. I take it you have had some troubles with him...?
I really want a full set of alloy pivot blocks and was thinking of purchasing his. Should I hold off and if so can I purchase these someplace else by chance?

Thanks again- Jason

He never sent me a replacement for the incorrect pivot blocks i bought off him. He is not trust worthy as he ignored my last few emails. Im unsure if the silver versions ive seen on ebay are made by him or someone else, if not him then may be another alternative.

Ok Ive had an estimate so is not confirmation on costs yet but the tub chassis could possibly be around a £120.

As mentioned this is not confirmed for definite yet but if it is that price then I think that this is worth buying several.

What do you guys think?

Also after a discussion with Dan ive amended the screw driver hole to screw on or off the left gear cover and have extended to hole to an oval shape and believe may resolve this once and for all. I also didnt like other things Com Com did to my design such as taking out the oval hole for the servo so put that design back in as per the original proto type as it worked well. Ive also kept the wider rear end as on jimps the wider section gives more strength therefore protecting the chassis more. The bumper end a normal bumper does fit without issues.

Chassis on the left is a hand made rubbish, the one on the right is the original with break in. As you can see the rear end I was describing and also the servo holes and you can just make out the screw driver hole bottom right which will be extended left and right.

It was done using the undertray as the base and didnt come out well. Holes were manually drilled so not in the correct place. Its basically no good but had it for fibrelyte to use as a starting point that was until i got my hands on my original chassis on the right

[Skidrow]

I see. Materialwise is it good? Thickness compared to the fibrelyte one?

Not really, it feels rough and brittle but is expected for a home made chassis.

The tub from fibrelyte is perfect however and they are basically the only maker for this car. Yes different names like comcom or wasp but all made in the same place but not with the same cell layout as per my right picture. This is a quality piece of kit, i used my proto chassis for ten years, three club events a week plus a race on the weekend and was still in good nick when i sold it on. The intention for the design was to protect my servo and esc from marshals feet and less flex but didnt realise how good a design it was.

Great to see progress made on the new tub. I'm definitely in for one.
All this talk of tubs inspired me to mock up some parts on my used tub, I'll post some pics before the weekend is through

[HKS_TRD]

As promised some pics of my tub, along with my current Lazer collection of ZX, ZX-R MKII and ZX-S
Its only a mock up with parts that are meant for the ZX, some anodised bits are still in transit and it needs a strip and all new srews and a thorough clean.
I marked in Red where I need to cut the tub to fit the ZX body, as I am building a second tub I have almost decided to use this tub on the ZX shelfer.
I've already got a genuine clear gear cover on the way, I didn't like the way the repro one fit it was a little tight, probably works fine on a MKII where the front edge needs to be cut off anyway

When I strip it I'll start a new thread for it, sorry for all the pics

[Welshy40]

Nice, i see they made a design flaw with the steering side sections. My original design was perfect and they tried to make it better. Doh!!! Still never thought the zx shell fitted.

[HKS_TRD]

Hi James

Can you post a pic of the steering section of your original tub?
I'm still at odds about cutting the tub but think I most likely will as its only a small mod

The ZX shell doesn't fit the ZX-R undertray and it turns out that after I have done this mod the ZX shell will probably fit the tub better than the ZX-R shell. The shell of my yellow MKII which is a genuine shell and not a smaller repro is a very tight fit around the front area of the tub

Hi Welshy40, I have finally got time to run my LWB mid at a newly opened dirt track near where I live, and I find that the car holds up well in the rough stuff, no broken parts, just a few screws holding the shocks came loose. and the slipper works great. However I fond that the car does not handle the bumps so well. The track isn't smooth, with a lot of bumps and ruts, I had my car overturned countless times. of course this track is more suited to the 1/8 buggies. Is there any tips you can give me to make my car not be thrown off so easily when its in it's course. I really have trouble with the back end hopping out. Also , a startling revelation, The old kyosho tyres for the ZX-R, the W-50XX series, they actually grip better than the modern j concepts soft tires! Does kyosho still make those tyres ? I will be starting the new layshaft proto today.

I find softening the oil by 5wt on the back and maybe going down a spring strength is a good starting point. Maybe also trying a roll bar. Front oil should be heavier fractionally and also a heavier spring compared to the rear.

[Welshy40]

Who was after a Hyper clutch recently? I can locate a slipper disk where the spur gear attaches to but will be pricey unfortunately.

Also the correct part nunber for the layshaft is LAW12-1Z and you may find this on the japanese ebay.

Two available here. http://www.ebay.co.uk/itm/Kyosho-LAW...#ht_1599wt_958
