Does anyone have RCCA magazines left ????

There is an pic in there somewhere of the HPI ZXR chassi

:drool::cry::woot:

Well, got my Lazer ready to go.
Not a faithful restore by any means, just something to go racing with :thumbsup:

Found the following page on google. Unfortunately all in Chinese but can be translated. Does anybody know what brand the 4th chassis plate is...HPI perhaps???

Nice I'm guessing your using Alcyons layshaft but what slipper is that?

Nope, looks like the TV chassis for the pure ten car, quite possibly a zxs but see no kick up

Yep, layshaft from Alcyons. Just the AE VTS slipper.
The spur gear is AE 93t 48dp originally off the SC10 4x4, I preferred it as the smaller gear gives more clearance for the shell until I get a spur gear cover and another shell painted.
Guess I should back it off a bi though as it wheelies now :woot:

And then there were 2! Off to their owners today

Big time as the belt will snap / shred if you dont. Set it so its a fractional slip from start. Don't over do it as you'll ruin the slipper pads. Picture quality wasn't spectacular so wasn't sure if it was a vts but the spur did look smaller, but be warned may cause issues to the motor due to a bigger ratio. Still game on and have fun.

Welshy,

A spur gear with 93 teeth is only 7% smaller than the stock one. Can this not simply be compensated by going down 1-2 teeth on the pinion, with the benefit of having a reduced rotating mass?

Looks awsome paintjob top notch body with inbuilt gearcover soo cool do you have more of those bodies ???

Med vänlig hälsning, iso

not sure awsome find

the carbon looks similar to the hpi upperdeck so i cant rule i out but i cant say that it is an hpi chassi. what i recall the hpi chassi was for the zx/zxr not the mk2 and that chassi is drilled for the mk2 i guess due to angled batt bars
so the topdeck wouldnt fit. But i cant say neither is or isnt. awsome find any way even douh the text make it hard too read. :woot::woot:

What i recall regarding the hpi chassi, it was sleeker like the chassi in the pic but had been lightened between the cells. so i would say if my memory serves me right that TF3R chassi has the look of it without the lump for the servo on the tf3r

but i have seen more then one race car that has had theire chassi cut like that so like atushi haras lazer zx car you know hara hpi ????

on the other hand crusaderlyf i have been on him regarding the hpi chassi so could be it if my memory doesent spook me
would love to have the rcca that has an pic of it.

ahhh so cool

With this car I think I based my ratios on 1.5 teeth to a half pinion tooth so if your after less punch I would gear up so if your wheeling I would suggest gearing up or lowering the esc settings, plus also helps setting the slipper correctly as well as it makes a huge difference as I've proven when developing the layshaft.

I am confused, when you say 1.5 teeth for 0.5 pinion tooth, do you mean that you use a 33 teeth pinion with you 100T spur?

This is highly geared compared to what I have with my brushed motor. Is it because brushless motors have much more torque?

Well I'm using a 19 with a 4.5 and normally it's 2 pinion teeth per wind up for this motor but it's all down to you and how you feel. The car shouldn't wheely with a standard gearbox, even though I did manage it with a ten double corally in the 90's. The belt is loose in the gearbox and tensions too much and stretches under immense stress due to not having tensioner in there and then the belt frays meaning a new belt and pulley will be needed.I've designed a tensioner for the current gearbox but am contemplating a 3 d design with the tension post sections built in thus resolving everyone's problems.

If you could tension your belt then great, but still the same problem as with my cars gearbox with all the tensioners i get the same problem with testing, car can't handle the power without a properly set slipper. Don't forget the car was designed for brushed motors and was perfect for that but I've had to redevelop it to work with the torque from these brushless motors and had to put ceramic balls in the diffs, tungsten carbide thrust race in the diffs, ceramic bearings throughout the car, stainless steel screws and redesigned the tub chassis for more strength and with Rama's help we designed the layshaft for a B4 slipper which then evolved to a vts. I tested it at Maritime raceway and started off three laps off the pace, after gradual layshaft development and working out which slipper worked best I found out I was two laps better with the B4 slipper and with the vts 2.5 laps better, then it was the layshaft to finalise as it never lasted in the prototype stages, in fact I only ever finished one race event which meant we were still off the pace so tweaking the design was needed to get back on the pace. I've gone on a bit and hope I make sense but ask away any questions and will try my best to help.

If your running fast motors, belt tensioners are a good idea to extend belt life. I've been racing my lazer zxr for the past 4 years now and never had to change any belts/pulleys (6 meetings a year on eos carpet)
Using a 6.5t brushless 24 pinion ,standard spur, original diff balls etc and layshaft set up. The only thing I've changed from original in the drive system is the added belt tensioners and the slipper pads , I'm using ae b4 pads.

Ta, that was my basic paintjob I used around 15 years. It looks good because I didn't paint it :p
I can't be certain but I think the shell is an old Racecraft one, not something I'd picked up new unfortunately. I will be getting a gear cover to be able to get my more modern colours painted. But the simplicity of the all in one shell is so much better IMO.

Got the chance to run the car today at the Dudley winter series and it lived up to expectations. Once I'd got a balance with the tyres I could push it quite hard (although still not to modern levels by a fair bit) and it handled it very well with a 7.5t motor (geared 23t/93t).
Thanks for the info on belts but I won't be driving it on EOS carpet so that will take a fair bit of the strain out, I'll modulate it with my thumb :woot:

I just received my shaft and only have 90T spurs at the moment. I'm running a 10.5T and the smallest pinion that will reach the spur is a 28T. I'm surprised even with a 93T spur, that the 23T Pinion will mesh. I need to find some bigger spurs asap!!

Thanks Welshy for the reply,
Where could I get this custom B4 slipper layshaft?
Can I use a brushless motor without a rear belt tensioner? If yes, would 13.5T be good to start on a carpet track? I am a "pro" basher, but still a beginner racer.
Thanks

To be honest with a 13.5 you should be able to run the standard slipper clutch and belts without tensioner. You'll just need to make sure cars in good order but we all do so should be fine.

would anyone have a set of Yokomo TH-6 wheel adapters and the Yokomo wheels for sale?

Nope dont have hm but i do know where i can find a set ,Shall check


Mvh iso

Thanks
Are the Yokomo wheels to suit pink 2.2"?
I may have a lead on the adapters but trying to figure out wheels are correct to use on a ZXS

Any yz10 93/94 version wheels, the car Masami won at Basildon in the UK.

Thanks, is there a part number so I can start searching on eBay. I'm not familiar with anything outside of Kyosho lol

CAD files
 

Anyone have any of these things drawing up want to used them to check my gear box design.

Looking for:

LA-32 (front gear box)

and

LA-30 (suspension hinge pin holders)

Many thanks

Liam

Liam,

Alcyon I believe has, give him a try.

sway bars
 

Does anyone know if there are sway bars from modern cars that can fit on the lazer zx(r)?
Thanks,
Ubi

Tbh never tried.

Welshy,
Do you use sway bars on indoor carpet?
Thanks
Ubi

No, only outdoors. Mind you I love twitchy cars with looser back end but still with grip and found it was better without on carpet and slippery tracks but on grass and on clay high grip I used a rear bar

Does anyone have a Kyosho la-103 for sale
I have a new LA-122 shell as an incentive

Guys, better get in quick, hope all Lazer fanatics have a great Christmas. Wishing you all great racing for next year.

Lazer ZX-RR resto, special knuckle arms
 

Hi,

I am currently restoring another ZX-RR (Equalizer shocks, Hyperclutch, ...).

I realized that the car is equipped with some special front knuckle arms (see pics). They seem to be Kyosho but maybe from another car???

Does anybody have more info on these knuckle arms?

Thanks and best

Ralf

Pretty sure they're from the Kyosho pure 10 series of cars.....part number SD032.

Anyone got anything new, been a tad quiet recently.

nope not for now but soon im the making :lol:

and i shall have some work for you soon

3D printed parts
 

I have durability issues with some of the parts I got 3D printed by Shapeways in "versatile plastic". They have a new material called "professional plastic" that is supposed to be stronger and more durable, but it is twice as expensive!
Has anyone tried this "professional plastic" material. And if yes, is it worth the extra money?

Thanks,

Ubi
