That does look nice. I've seen the Marwan stuff on eBay and it looks good. His kit doesn't include an undertray but then there are some other ones on ebay.

I have one of these hybrids too though its still not quite finished
The only difference left is the gears in the rear gearbox instead of a belt
Some of the other differences actually make the Mid more like a ZX-S than the ZX-R

I am using a Team Bluegroove undertray on my "hybrid" as it's using a standard Mid body on an LWB chassis, so I had to cut the undertray at places to make the body fit. The first attached pic shows that.

The TBG LWB Mid undertray is reasonably priced, but a little too short. I had to sand off a slight edge on the chassis bottom plate and make the fold on the rear portion, that is secured with screws to the rear gear box, a few mm more to the rear. Check the second attached pic to see what I mean. Their SWB undertray fits better.



Great looking car, I posted some comments in your thread.

Try my sponser, Kamtec, links below and look at the ZXS and mid shells and you should find the one suitable for you

I feel that the lwb mids are just as competitive as the lazers.if fitted with lazer suspension. I always feel the main advantage the lazer had over mids was much easier servicing. My lwb is a star performer as seen in my latest video. That durango kid was really miffed !
I beleive now my problem of stripping spurs on my zx is caused by the tbg gear cover not covering the gpm motor plate properly. Anyone want to trade a standard zx plate for my gpm ? I will test My lazer this Thursday, hopefully it wont rain and the track will be dry too.

Rama,

A standard lazer ZX motor plate is on the way to Kuala Lumpur!
It's a used one but still fine for a runner! Let me know once received mate.
You can keep the GPM plate, no worries ;)

It looks like it drive great Rama I love the old stuff out gunning the newer cars the looks on there faces is priceless.

Interesting, great if its just that.

Rama it shows whos the better driver and looked really good. Jumped well too. Id love to come down one day if its ever possible with mine and have a blast with you guys. Ive never been spot on on low grip surfaces but with a bit of practice and setup changes i think we could dominate.

Oli. You have been a great help.i could always send the gpm plate after my testing.
peakey..yes the feeling is priceless, thats why i still continue with a vintage buggy.
welshy40, thanks for the compliments, but i feel i am only slightly above average skill wise. That durango kid beat me in a race in june, and he is actually pretty quick too. my car is much better now because of harder springs and 7 degree zx5 caster blocks otherwise he would have beat me again. You and any oople member are most welcomed to come to malaysia for a vintage race or even to compete head on against modern cars.
J77MYF , sorry for hijacking your thread. I have a swb mid just like yours, and i am still trying to improve its handling. Its working pretty well at this moment but i am working on some tweaks to make it better , i will share what i learnt with you guys

My SWB at the track with 30wt oil and Hobbyking quonom vandal tyres.
I swear it was running better an hour before this. I realized after this video was taken, one kingpin fell off.http://i185.photobucket.com/albums/x...psskoifqhz.jpg

That looks really nice. Do you have an undertray on it? I've tried mine with a 10.5 beushless setup and it loves to wheelie. It's a lot of fun to drive:-)

Yes I use a TBG undertray. It wheelies because you don't have a slipper clutch. Try reducing the punch too.

The new body set arrived from Marwan earlier this week. I painted it last night and put the graphics on early this morning. Just got the wing to sticker up tonight. Attachment 74628
I'm using the LWB undertray cut to the chassis rather than the SWB one. Hopefully I will be racing it tomorrow night for the first time in over 25 years at my local club.

Looks nice. Can you show how you cut that undertray?

I got the LWB undertray and cut it out to the shape of the SWB chassis. I tried to keep as much of the tray as possible but it just wouldn't work. I'm only running the car indoors so it should be fine.

I see, it's more a chassis protector now. I faced a similar challenge, as I wanted to fit a regular Mid body to a LWB Mid, for this "hybrid" Lazer/Optima Mid contraption.

I was able to keep most of the LWB undertray sides intact, except on the front part, as the SWB body follows a different shape than the LWB bodies there.

The finished car all ready to race tonight.

That's a nice car. I also have a Lazer ZX which I'm going to put the LWB Optima Mid body and under tray on. Do you know if that will fit straight on?

Hi,

Where did you run it & how did it go?

That looks just awesome!

Thanks guys :thumbsup:

I'm running it tonight for the first time at my local indoor club called 10 Electric in West Yorkshire. There's a few of us who are interested in a vintage class in between the modern races.

I'll let you know how it goes.

Thanks. For more pics, check my "car collection" topic, shows how it looks witb swb body on.


As far as I know, the Lwb Mid body should fit. I read that some drivers didn't like the zx stock body, and fitted the lwb Mid one instead.

That is true. If you read rc car action mags from 1990 to 1992 before the zxr was released you will notice most of the zx were running lwb mid body.

Seems like my memory is still working, more or less. :D

Are these mags up for download somewhere? Would make interesting reading on those cold winter evenings.

Thanks again for the info.

I raced it last night and it was loads of fun. It is totally different to what I'm used to nowadays but it still did well and I really enjoyed it. I'm racing it again tonight in York tonight.

I've also spaced the top deck with a couple of washers so I can fit a hard cased Lipo in.

Just click on the pics. You will be directed to my photobucket. You can find the rest of the articles and save them.

Different in what way. Care to elaborate ?

I've not driven a 4wd car for over 20 years and it's super short compared to modern cars which makes it feel a bit different. I drove it again last night in York and I just missed out on getting in the A final 4Wd modified class but won the B final. The rear suspension feels a bit lazy and I think it's due to using the lazer tower and the shocks not quite lining up properly.

Mate, your car is awesome!!

Everyone loved watching you give it full beans!! To say it's your first weekend out with the Mid the performance was amazing.

The only thing that worried me a little was the poor old gear box taking the strain!!

Thanks for that and I'm glad you enjoyed seeing it in action.

The gearbox is a bit noisy but I do have a brand new upgraded one ready to go in. I don't think I'd dare run anything faster than the 10.5 brushless setup.

I really enjoyed driving it and people who've had and remembered them talking to me about it.

The mid has a very silent driveline. If yours is noisy could be you are using a pinion of the wrong pitch. It does not use standard 48p but 0.6 module which is the same as old tamiyas.

That's a good possibility. Or the diff and center gear are worn.

I bet it's the pinion as I didn't realise they were different. It does sound like the pinions tight.

Is there any video of that race?

think i may have some .6 pinions if you need one, just let me know what sizes and i will look if i have one. just been talking with Danny harrison today and im guessing you know him and it was your car hes was talking about with me today?
if so why don't you come along to the next bury indoir meeting and we can have our own vintage race lazer zxr vs optima mid.

I don't think anyone was filming it.

Hi Rob,

That's very kind of you but I've ordered a couple off eBay.

Yes I know Danny Harrison and it was my car. I think I was speaking to you earlier this year at Batley? Yeah I'm definitely up for a vintage showdown although I don't think I'll be able to keep up with your lazer ZXR.

I dont know what you mean by the rear being lazy.. but in my experimentation the lazer rear tower works better on the mid.
you probably need harder springs.

on mine the lazer rear tower leans the shocks back and they become tight. Did you use longer bolts with the lazer tower and space the shocks forward?

http://i185.photobucket.com/albums/x...psc2f29bf1.jpg
Look carefully at this picture. When you flip the Mid rear arms, it will cause the rear dogbone to be swept forward. They will no longer be inline. This will cause the rear suspension to be pulled down under acceleration, besides the inertia force present. This will affect handling negatively. To counter this, you need to grind off 4mm from the arm to shift it . Grind off from as shown in pic, which is the rear, then space the arm with washers as you see, this will push the arm rearwards and make the CVD exit the diff outdrive in line, the way its supposed to be. And please feel free to use non original bolts, if longer is needed, then use them and space them correctly.

This is the rear end view, as you can see its nothing special, but I use Mid rear towers which is flipped behind.
http://i185.photobucket.com/albums/x...ps5144d6d1.jpg
this pic shows my LWB mid with ZXR towers and ZX arms. With ZX arms no grinding is needed. I have plenty of used rear arms so if you are afraid to grind yours I can give you some.
