Lazer zxr

[isobarik]

You have to fit an crush tube if you want to tighten the nut really hard.

James, What kind of battery posts are you using on your lazer?

Dan,

I think the issue is the actual knuckle arm and the metal poles on either side of the uj as i had that issue with mine. Think the knuckle arm is a zx5 and also could be the issue. Do you have a cad drawing of that front pivot block plate?

ISO what do you mean by crush tube? Where does it go and where can I get one? Do you run these hexes and axles on your cars?

James, the knuckle arm is ZX-5, I tried OT-16 knuckles and had the same problem. I just went by what Oosh did but maybe he machined the inside of the hubs to place the bearings closer together or the back of the drive washers. If I run the the axles which are slightly longer and are meant to use a spacer I can just trim the spacer down, I'll do that on the rear.

James Stephen copied an original Mid pivot block plate I sent him but changed the top edge as per a drawing I sent him so he should have it on file. I made a mistake however because in my drawing I asked him to remove all four holes when two of them are screw holes 'doh. But thats OK as I laid it over a metal mid pivot block with the wishbone shafts holding them together and drilled through the holes in the metal part to get the screw holes in the carbon plate to line up perfectly

While I'm on the topic of this mid I'm dummying up, I'm trying to decide if I get the rear bulkhead anodised blue or polish it for some contrast against the motor plate. What are everyones thoughts?

[Welshy40]

Blue it.

Also Iso said a crush pin which is like what associated use where you need to crush it to put into place as its kindof spring loaded.

They are almost identical to the zx plastic item hence why i opted for it. Unsure of what they are called but do a search on lazer zx5 battery posts and hit images on google and its just a search and hope they are available. Pics are there so good hunting.

OK I think I understand where is the best place to source such a thing?

looks awsome ...
for the crush tube use an old bearing sand it if its to long .

look here http://www.oople.com/forums/showthre...t=48668&page=8 at lukes solution.

Bearing spacer and as shown take a bearing apart and use to space but i think the issue is the hub and the mold bearing section is slightly narrower so good idea to do this but itll take some work.

Thanks ISO, I've had this project in the works for quite some time there are barely any Mid parts left on it bar the gearbox cases, once I have the rest of it dummied up I'll strip it and do the final assembly and post pics.

That link was very useful, it turns out the 3racing knuckles come with a crush tube just someone didn't realise what they were (I've never had a car with crush tubes in the hubs) so now all my hubs are assembled and ready to go. I had to sand the crush tubes a touch but that was only a 5 minute job

I guess I got lucky in having the crush tubes come with the hubs

Did anyone spot the Lazer servo plate on the mid chassis? The chassis is another one off Stephen did for me based on the LWB mid chassis but with some Lazer DNA thrown in for good measure

Yup spotted a few designs that look similar to mine

The front shock tower is your design with the hoop across the top removed.

I had a pair of your ZX-S style shock towers hear as well but I am saving those for my shelf tub

I have a few bits together for the runner tub too

I have discovered that you can't really put a sway bar on the rear of a Mid with Lazer suspension as the spur gear/layshaft on the Mid sits alot closer to the tower and its all a tight fit, though I will look into it a little more
Those RPM arms which were white before I dyed them don't have the holes for the sway bar links anyway!

I have enough parts here now that when I build everything up I have 16 Kyosho buggies

How on earth did that happen!!!!!

And at between £250-£500 each from parts DON'T do the maths!

Those are from 3racing, ordered and they are on the way to me cheers James!!!
BTW: Can't find the tub chassis on the fibre lyte website

You're right, that would make you sick.....

I think it has a lot to do with knowing us, plus now we can afford it why not

Update on my race.

Practice day was a godsend as i had numerous problems. First issue was the alpha or 2000 wishbones snapping as impacts are not liked. Caused numerous problems but after that found that the original set up was close so ended up with no ground clearance on the rear and had the back sorted. Then got working on the front and tbh was a nightmare to find a resolve so wasnt satisfied when practice finished. Atvthe hotel due to a poxy gypsy wedding I was unable to sleep so ended up rebuilding the car and opted to give a bit more droop to the front shocks seeing as they were never limited in the 90s.

On race day the free practice was superb and the car was unbeatable, i blitz it and didnt make an error and due to that put me in a higher qualifying round. First and second round my zx knuckle arms would not hold my king pins so basically cost me a qualifying time and at this event best two count. Third run i was up to 3rd but messed up and finished 7th with a time good enough for the B. If i hadnt made as many errors i would have done another lap. Fourth round beforehand i decided to add 43 grams onto the centre section of my lipo tray holder bringing it up to with 27 grams of the original scrc battery weight and as i had nothing to lose put it on the track. i made a number of silly errors but put in a time i should have done in the second round and put me 9th in the B. The car was flat on the deck but was more nimble and also didnt cut the mini pin tyres at all and had a more driveable feeling. Still not happy about the front but i can focus more on that in november.

In the final i went from 9th to 4th and then my pinion decided to come off, gutted but considering the guys in front were quality drivers im happy where i am now, just need to sort the front out properly and then im going to give more.
