I thought I'd share my Paj with you all on here, seeing as it's one of my favourite models and it's been a kind of ongoing project over the last 2 or so years. I'll give you a quick run-down of what it's been through so far.

It's no match for some of the mad scale things that I've seen on here, but it does me fine.

How it started - A box of bits and a body with about 10 coats of paint:
pajerobits.jpg



After a few days of fiddling and an online manual, and a god-awful shade of matt grey :oops: At this stage it was bog standard, as I was just getting to grips with it :

After a while I read up about the 4 link rear suspension you can do to the rear axle, and gave that a go. I sourced the parts from ModelsportUK:
4-linkparts.jpg



.. and set to work fiddling around trying to get it set up as best as possible. Since I first did it, it's changed too many times to count. Now I'm at the point where I'm happy with the amount of performance I get from it as there's a good dollop of articulation, but decent stabily at moderate speeds too. This is how it was at first install (forgive the wonky-ness... and mud):
4-linkunder.jpg


And that gave a pretty decent amount of flex:

After that, I got bored with the paint job that seemed, literally, to be getting duller by the day, so was inspired by a neighbours car and painted it a more normal, brighter colour:

These were taking during one of it's runs in my Mum's flower bed:

I'd been thinking about it for a while but decided to go ahead and bite the bullet. The front suspension is, along with the steering, one of the worse parts of the XC in my opinion. My solution was to drill two holes in the chassis above each of the front shocks. This allowed me to fit 4" shocks to the front, and after some innovative mounting, I managed to get them set up. The front now provided a good amount of travel, a lot more than before, and I'm pleased with it. This is after front suspension mods:

At one point I found a couple of spotlights off another model lying around so I mounted them up. I also used an old cut up speaker cover to use as "light covers" which, I thought, looked pretty good. Although on the first run, I managed to lose them, so that was the end of that:
PajLights2-1.jpg



I can't sit still for very long, so I started having wild and wacky ideas of how to change the body up a bit. So, with my two (tiny) pictures of what I was aiming for, I set to work:
PIAA_Pajero2.gif

I'd never done any body work before (well, I've done a bit to real cars, but not plastic), so it was a good experience and a learning curve, as much as actually getting it done. And I really enjoyed doing it. Basically, what I did was first cover up the inside rear windows with fibreglass. Layers and layers and layers of fiberglass. Smelly stuff that "thumbsup" When that was done, I moved onto filler, and after layer and layers and layers of that, it was time for paint. After the first coat of primer I saw all the imperfections come out, so sanded it back and added some more filler. I wasn't toooo fussed to be honest though as I'd be running it into the ground anyway. So, this is the end result:

Since then, I've painted the chrome front and rear bumpers black, to stop them sticking out like a sore thumb.

At the moment, it's in bits as I've stripped it down to give it all a good clean and freshen it up a bit. I'm also making an alu front skid for it. I've got some Rock Stompers coming in the post, not sure how well they'll fit but I'll make it work.

I'm also having ideas about new bodywork after seeing everyone elses on here. I'm thinking about chopping it straight down, just behind the front doors. Then, making a bed for it, and maybe some sort of cage. However, I've never worked with styrene or welding / braising before, so if anyone could give me a link to some decent guides, I'd be most grateful.

And that's it for now. I'll get some pics when the new rubber gets here.
 
Nice job on the paint. I just picked up a Pajero a few days ago and can't wait to get started on it.

Well done!

Enjoy building it, I did.

This is, actually, the original version of the Pajero, none of this re-release malarky :lol:
 
Very nice! I loved how the rig seemed to get better as the build went on and the experence increased. Paint and headlights look great.

Yeah I don't know about those stompers I have them and they are just way to big to use in a XC chassis. Geartrain wise and fitment wise I might suggest other tires.

If your looking to increase performance, I'd mount the lower 4 link rods to the outside rails of the chassis by drilling new holes. The ground clearance and skidability is just so much better it's nuts.

A 3:1 reduction unit makes a huge huge difference in the crawlabilty especially if you plan to run the stompers. Truck seems much much more under control. Although useless if you like the high speed.

The front skid that your planning make also makes a huge huge difference in crawlability and realism.
 
Thanks for the tips Mnster.

One of the things I've noticed when driving it is that the lower links do get hooked up on obstacles quite often but have never thought of a solution. I'll give what you mentioned a go, sounds like a great plan. Does it have much of an effect on the way the rear axle articulates?

At the moment, and for quite a while now, I've been running a Graupner Speed 600 motor (600 size) which provides loads and loads of torque. It's not fast, but I don't want it to be. I had to cut away at the chassis a bit but it's definitely worth it. Like you say, the Paj feels much more controllable. Would the reduction unit be much of a difference over this?

For the front skid, what thickness of sheet alu do you recon I'm best of using? (Never made one before, as you can probably tell)

Thanks!
 
Yeah I had my rig your way with the links and I seemed to get caught or hung up on everything. Everything from wood chips to rocks. After I made the swap the rig no longer hooks on to anything just sort of slides.

As for flex you can see my rig here.

I made my skid to thin after a few hits it dented and got all bent. I would go in the range of .060 -.065 thick. or 2-3mm depending were you live.

With the reduction you loose the stalling. I'm sure you know what I mean, one of the tires rolls up to a rock face, motor gets loaded down, motor stalls, you increase throttle to manuver over the rock, as soon as the tire is over the rock, Wham the truck sprints away as you still have the throttle up. With the gear reduction it's almost as though you have your hand on the truck pushing it along. Watch that video above, driving the truck just seems much more realistic as you loose the jumpyness. Manuvering difficult lines with ease really makes it feel like it's a 1:1 and your in the cab driving. It's just that kind of control.

Here is a video with motor sound to give you a idea of the throttle control. Notice how slow the tires can turn and still not stall. I'm running a super cheap Ebay Brushless esc with a tiny light weight motor.

Damn you, now I've read all 36 pages of Jim's build, but it was worth it :)

Thanks very much for the help, really appreciate it. I'll go down to B+Q on the weekend to see what thickness alu sheet they have.

I'll keep the reduction unit in the back of my mind for now as I'm a bit tight for cash.

I've also re-located the lower link mounts to the side the the chassis to avoid binding underneath, and it seems to work pretty good. I'll try and get some pics asap.
 
Here's some pics of the suspension mods. First up, the rear 4-link setup with the lower links side mounted:

And the front suspension - hole drilled through chassis to allow 4" shocks:

And the mock-up front skid. Yes, that's cardboard:

Very nice!

Does the axle slide side to side under the rig much? I tried using a rod end as you did for the upper axle mount and the rear seemed to slop around. You could use two rod ends and long screw if it's a problem. I used a chunk of Alum I found in a box of parts. I don't like how I mounted it but it works as long as it is super tight.:lol:

Liking that skid"thumbsup" I had to grind a bit off that lower skid to get the skid to sit right.
 
The main problem with the upper link mount is that I can't get it completely tight, allowing the rod end to swivel either way a little bit. It makes the axle rotate a tiny amount when it does, but it's not enough for me to worry about. I tried the way you mentioned, using two rod ends and puttinga long screw between them, but found the screw always ended up bending, causing it to crab.

For the skid I tried a couple of different ideas, that one above is my favourite one. It bolts into two pre-existing holes away, which makes it easy.

Also, I decided to bite the bullet today and get on with my new plans for the body work. I marked it up and, as I don't have a dremel, had to cut it with a junior hacksaw but it went alright. This is post-cut:

Pajerobod3.jpg



Next I had to get rid of all of the old filler / fibreglass that I used to cover up the rear windows, which was a complete PITA. Luckily, a sharp chisel helped speed the process up. This is mid de-fillering:

Pajerobod4.jpg



Once that was done, it was a case of levelling out the sides and smoothing them off with a file and some sand paper, and a lot of lovely dust to inhale. This is how it sits at the moment:

Pajerobod1.jpg

Pajerobod2.jpg


Obviously, when I'm done with the major body work I'll strip the old paint scheme off and do something new.

I'm not sure what I want to do for the bed though, whether I should have one flush with the top of the rear, or a slightly sunken bed. Thing is, I can't sink it too far or it'll rub on the top of the chassis. Any suggestions?

how much of a cut did the saw make.. Like as in width of the cut?
I am trying to figure the best way to remove the roof and doors on a tamiya YJ Jeep...
Yea I'm going to cut it!
Your build is awsome, cant wait to see what you do next!"thumbsup""thumbsup"
 
that looks AWESOME as a pickup. I would do a slight drop bed, add textured paint then black over that. Its what I did for my crewcab build. I never worked with styrene either but got lots of good advice in the paint forum and on scale4x4.

working with styrene is easier than it seems. the thought of doing it the first time is daunting but actually doing it is easier.

here's mine
IMG_2381.jpg


after I added textured spray paint, then flat black spray paint:
IMG_2431.jpg



its worth doing the drop bed, even if its very shallow. especially then, the black will help it look deeper.
 
Crawler King, the saw I used had a blade with of 0.8mm, but I just had to allow for it when I cut it, so it wasn't a problem.

Pantablo, that looks very good, especially the bed. I think I will go for a slightly dropped one, like you said. How did you glue the bits together, with some form of plastic weld?

I've done a bit more sanding on it, just need to go and get the styrene and tools before I can start making the bed.
 
.8mm might be an accepatable loss... I was thinking I might end up using a jewlers saw or somthing.. I dont want to loose much of the pl;astic as I want to be able to reuse the top in the same way that the full scale ones operate...
I am also going to be getting into the styrene fabbing.. I am going to have to build up the top of the winsdhield frame and door jambs on the YJ as well as the rocker panel...

thanks. Yes, I used Plastruct Bondene and Tenax 7R (better). In some places I used 2 part epoxy and I often used CA to tack things together and keep them in place for the Tenax. If you search through the Paint and Body forum here for a How-To or over at Scale4x4rc.org they have some good tips for buiding with styrene.
You'll also probably need filler too. for that I used MMD green Putty available at hobby stores.
I think you're in the UK, no? If so you have different brand names there of all this stuff. Better check on scale4x4.org as there are many European members there that can help source the glues and fillers.
 
Do a search for "cutting with thread". There's an awesome how-to on cutting with practically ZERO loss of material... and awesome control. It's very recent.

its also very safe because it is slow and easy to control.
 
Well I went down to my LHS today and raided their supply of Plastruct styrene. I also got some sheet alu which meant I could get on with making the skid plate. Mid making:

Job done:

Skid2.jpg


I simply marked out the lines with a scalpel, then cut it with a junior hacksaw. Smoothed off the edges with a file then a bit of coarse sand-paper. Easy.

I also had a quick go at bonding some of the styrene together. I used EMA plastic weld, and after a few goes managed to get it sorted.

Some of you more eagle-eyes ones may have spotted that the Paj is now sporting a lovely set of Hummer rims, courtesy of eBay. Just waiting on those tyres now...
 
its interesting to me that so many people ask about a Suzuki Samurai body and this, with the back cut off, looks just like one to me...
