Evening all,

Just thought I'd show some pictures of my Tamiya XC offroading in the snow we've had biggrin Chassis is a Tamiya XC, long wheelbase, with a chinese Land Rover toy body. Front and rear locked diffs, standard motor for now, but I've got a 3speed truck gearbox which I'd like to fit, no idea how.

Anyway, its been a LONG project, and I finally though sod it, and boshed it together, glad I did, cause it's so much fun smile

Some pics:










Ignore the mess of wires on the roof please, need to re-wire the spotlights in!

Most of the work has been done on the Bodyshell to be honest, it used to be a normal defender 90 with a full cab, but I lopped a load out of it, bobtailed it a bit, and made a pickup bed for it, all made with plasticard smile Made a rollcage out of soldered brass bar (does have back stays but they broke off recently, need soldering back on...) and made a little roofrack. Its got headlights and sidelights (tailights too) and 6 spotlights off a Lancia 037 tamiya model (just bought the light bits, I wish I had a full 037!) And finally made a custom bumper, again out of brass, with a fairlead and recovery points for the winch (which is an old butchered servo, this is a heavy beast but it manages to pull itself clear smile)

I've got a load of pictures of the build on http://s4.photobucket.com/albums/y125/jimbobulon/P... if you want to take a look smile

The performance is good offroad, at my parents house theres a small wood in the garden full of obstacles, I'll get some pictures tomorrow of it driving around in there, at the moment I'm just having fun tazzing about in the snow biggrin

I hope I haven't come over as too much of a geek wink

Cool build, I'm guessing you're on Scale4x4RC?
That XC chassis is pretty capable, I see you've longer arms on the rear? TLT shocks?
Tidy exo cage too, mine was a bit of a mess, though it held up to abuse fairly well. I took it off as the who thing was too top heavy.
What motor did you use? How did you waterproof yours?

Your photobucket album won't allow me to view, can you change the priv settings? I'd love to see more pics!
The 037 lamp-pods are a great idea! You should look out for the Lancia 037 wheels as well.


I used the Kamtec LWB pickup for my Tracer build, it's nowhere as detailed as the hard plastic body you used.
I've a few build pics at http://www.flickr.com/search/?q=muck&w=4551263...
Unfortunately I can't find any photos with the roofrack and cage mounted, which is a shame, because it look damn good smile

I was on scale4x4rc, years ago when I started it! there was a full build thread on there, Might see if I can dig it out smile

The rear arms are a shambles, to be honest. I needed to lengthen the wheelbase to accomodate the shell, but ran out of rod ends so at the moment it's a 3 link setup which, to be honest, is crap. the rear end needs sorting properly, then it'll be more capable.

The front is even worse, I used solid rods instead of dampers, as the TLT shocks can't handle the weight of the chassis, let alone the body too lol, its quite capable as is though, and hopefully will gain a bit of grip from the extra weight, when I can find stiffer springs!

Just a kit motor and Mtroniks waterproof ESC at the moment, not giving me a huge amount of control though. I'm really trying to find a way to fit the 3spd gearbox in, but getting drive from that to the XC chassis is the final hurdle, I've no idea how. When I get it done, it'll have a super low crawling gear, just less than walking pace, and then a speedier one for general cruising (I hope)

need to finish the suspension off, get the gearbox mounted, then it'll nearly be done!

I'll try and sort the photobucket album now smile

Oh yes, and I'm going to set to with a spade in the wood tomorrow, make some more challenging terrain for it biggrin For now, I'm off outside again biggrin

Not mine, but one of my neighbour's models. An Alvis Stalwart 6x6 (all 6 driven too) 4 wheel steering, a helicopter IC engine and 4-speed gearbox. Pictured some time ago here:

Errr... I either added an extra planet gear inside the diff casing, or glued them together, it's been a while since I did it! With all 4 wheels locked it's actually quite capable, I think its great fun smile

Bugger me! Small world eh?! You'll know its been AGES since I built it then wink

I've got some more scale pics to put up, I've found the most perfect material for scale mudflaps, and actually found some springs that support the weight of the front now, so actually have front suspension, not solid tie rods biggrin

I need to work on the ESC, its not very controllable, and reverse is like 25% full power for some reason :S

Don't worry, mine's a Work in Progess for the last couple of years as well! I've stripped off most of the cool bits from my Muck Warrior build, either through abuse, or to improve performance. It's back down the the bare sehl now, no lights, no rack, and the shocks need to be rebuilt. I've not done much with my RCs in the last year or so, the house and other 1:1 distractions have got in the way biggrin.

very nice picture you got there, but very much doubt that would be able to climb the same sort of scale incline that some of the other pictures, being RWD and all

No, and it's hardly a "scale off-roader". It's a large scale (FG?) petrol buggy.

Its off a cheap chinese R/C toy (simple 2wd plastic thing) simply nicked the body off it biggrin

on the scale4x4rc forums, a guy called RA0128 (I think) has a handle on them, he's an individual but sort of imports them as a hobby as I understand it. Or failing that, eBay!

Made a few changes to it (trimmed the bodyshell and arch flares, as it was getting stuck in the mud. Rear suspension is sorted, and quite miraculously, works really well! its got a load of droop, and the dampers can dislocate to allow for extra long travel, scale wise, its got just over a metre of flex in the rear suspension hehe

That chassis looks good, but I don't really know! The Axial SCX-10(?) is highly rated from what I've read? Shame the XC has independant front suspension really!

yes, the Axial SCX is a good chassis - I have one of those (as well as a couple of competition rock crawlers smile). Thinking of getting the RC4WD chassis and going for a Land Rover hard shell for it

Hi there.
Just stumbled across this thread whilst browsing the PH forums. I am well impressed with this. I have been considering building a half-scale 90 for my kids for some time, but this looks to be quite expensive and would cause problems for transportation and storage. This model seems to be much more of a plan!! I assume it's 1/10 scale? Where do the wheels and BFG tyres come from? Where was the cheap plastic body sourced? I've not done anything like this before, so what's the cost likely to be for a chassis, servos, remote handset, motor etc? I have looked at Kamtec who do a basic chassis etc kit for about £100 - is this a good starting point?
I'm going to do some more research now - wish me luck!!

Be wary of Kamtec, I have heard some absolute horror stories regarding them, and my own experience was not much better.
