one of the Axial SCX models is a good start, try someone like Modelsport http://www.modelsport.co.uk/?CallFunction=ShowSpec...

depends how much you want to spend and how much you want to build for yourself really?

also have a look at the forums at;

www.ukrcrc.co.uk and www.scale4x4rc.org/home/

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!!
Thanks smile

The scale is about 1:8.5, but I used a 1/10 scale Tamiya XC/CC-01 chassis, which is a good starter point (and great fun to build biggrin) (this pdf file is the build manual, which shows you whats involved with making a kit, you can get them pre-built though smile)

I can't find any of the bodies on eBay at the moment, but they usually crop up, a red defender 90, mine has had quite a bit of bodywork to be fair but take a look at this thread http://www.scale4x4rc.org/forums/showthread.php?t=... for some ideas of whats possible (there are some VERY good builds on there smile)

Cost is probably £~100 for the kit, £50 for radio and a battery or two, and then maybe £30 for the landrover body and some bits and bobs, the BF goodrich tyres are tamiya ones (come standard with the touareg) I'm running them on some tamiya 2 piece wheels for a bit of bling biggrin

Check out rc4wd.com if you want to spend some money, they have some cool stuff, like steel beadlock wheels, winches etc (I made my own winch out of a servo, which is pretty easy when you know how smile)

Hope that helps, heres some pics of todays outing biggrin







I got beached on a brow here, so why not just winch it out! (a longer, more tedious process than just picking it up, but I was trying to be scale wink)

Hi there.

Thanks for all your replies, it has now given me something to think about.

Mr.Jimbo - the PDF file didn't appear in you listing (or am I being daft?!)

I am fortunate enough to have a 1:1 90 Defender as a 'template' so can use this for measurements and ideas etc.

£200 sounds about what I was expecting although I would like to attempt some scratch-building (to get the best balance between scale model and toy) - but ideally would like to achieve something my 5 year old lad can use as well!!

I'm intrigued about the winch! Does it just use a motor to wind in as I thought servos were just linea? Must do some more reading!!

It will be nice to work on a project that can be done inside for a change instead of in a cold garage/driveway!!

In most RC servos there's a potentiometer connected to the shaft to limit the travel, but you can take it apart to bypass the pot and associated gubbins which leaves a motor that's controllable from the radio. I think Jimbo has a gearbox betweent the motor and winch drum to slow it down and increase the torque.

Sorry! forgot to put the link in! http://www.tamiya.com/english/rc/rcmanual/cc01.pdf

Using a servo as a winch, , you just have to remove the circuit board out of the servo body itself, leave the potentiometer at 0% (otherwise it will always run in one direction or another) and then use wires to connect the circuit board to the motor (the motor is soldered straight onto the board in a servo)

I can get pictures if you like, but thats all the modification I did really, I added a 7.2v BEC plug to the servo board, just so it has enough power to pull the thing (can pull the whole truck off the ground, which comes in handy biggrin) and it works great so far smile I just mounted the servo in the front of the chassis, and used two round servo horns as a winch drum, the servo gearbox seems to be strong enough, and just the right speed smile

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
It'll climb whatever you put in its way.

The incompetency is deceptive.

Thought I'd 'bump' this thread as, after 3 years, I've done nothing towards building an RC kit. With he lad now being 8, I think he may be old enough to use one sensibly now so am again thinking about a build so thought this thread would be a useful reference. I've been reccommneded an Axial SCX10 Dingo as, although expensive, would fulfill all my desires (apparently) smile

Ha ha - I've just found this thread again whilst looking through my old replies! My lad is now 10 - he was 5 when I first responded and I've still not built a kit. What we have done though is bought a Tamiya Lancia Delta to see how he gets on with it. Having looked at it the kit form is recommended for 14 years and over so I've got plenty of time yet smile. I've bumped this post as it has lots of useful links I might need to find as I think I will now sort myself out with a kit. The Lancia is a good starter kit but already there are limitations where is is only really good for hard surfaces. Watch this space smile
