Land Rover series 2

September 6th, 2010 Leave a comment Go to comments

My final 2010 Truck Trial vehicle, built in less than single week after the previous vehicle failed. Features full pendular suspension, 4×4 drive, lights and opening doors, bonnet and rear board.


Completion date: 03/09/2010
Power: electric (Power Functions)
Dimensions: length 48 studs / width 26 studs / height 27 studs
Weight: 1.985 kg (1.726 kg in roofless version)
Suspension: pendular, stabilized with shock absorbers
Propulsion: 1 x PF XL motor geared down 5:1
Top speed: 0.8 kmph in roofless version
Motors: 1 x PF XL, 1 x PF Medium

When I decided to abandon my Fiat SPA35 model, it was just a week before the Truck Trial race and my first decision was to pass on driving this time and to only take care of filming. Shortly after, I changed my mind and decided to try some simple 4×4 vehicle, just to drive something in the race. The vehicle was intended to combine the advantages of my two previous Truck Trial vehicles – Hummer H1 and Jeep Wrangler Rubicon, while also learning from Fiat’s failure. I wanted to try to model another famous 4×4 vehicle, so the classic Land Rover series 2 (dating all the way back to 1958) was pretty much an obvious choice.

While the complete model appears much like a Hummer/Wrangled hybrid on the outside, it was internally much closer to the Fiat model. The chassis was built completely with studless parts and used large Technic turntables to hold suspension modules in place – both solutions tested in the Fiat for the first time. The Land Rover shared engine location, gear ratio and wheels with the Wrangler and a studfull body with the Hummer. In fact, the Rover used studfull body around a studless chassis, whereas Wrangler used studless body around a studfull chassis.

The suspension has undergone some major changes in comparison to the version used in Fiat. The front axle was reverted to the version used in the Wrangler, and then a single turntable was attached behind it and the steering system was additionally reinforced. Both drive and steering were transferred through the turntable – steering by a solid driveshaft and steering by am empty differential sitting on it. The rear axle was built from a scratch between two turntables. There was no gearbox, and – just like in the Wrangler – the drive motor was located above the front axle, right under the bonnet. The racing rules we use state that every model has to be equipped with a piston engine of accurate configuration and placement, unless the actual drive motor is located where the original engine is. Thus, locating the motor under the bonnet meant that no piston engine was needed in the model, which saved space, weight and drive motor’s power. The steering was controlled by a single PF Medium motor geared down 15:1 and located low in the chassis, in front of the rear axle. The entire underside of the chassis was covered with studless parts, in order to create a single smooth surface that was unlikely to get  stuck on an obstacle, and in order to lower the centre of gravity as well.

Knowing that my Wrangler model had abundance of torque, I wanted the Rover to be much heavier.  Our racing rules take power-to-weight ratio of each individual model into account, therefore more weight at the same power means more points. Thus, I wanted the body to be massive, but at the same time it was my goal to keep the model’s centre of gravity low, despite its significant ground clearance (up to 7 studs under cabin’s floor). Therefore especially the lower portion of the body was built so densely that model came out almost undamaged from some crash tests I conducted later.

The body was equipped with a pair of opening doors, an opening bonnet with a spare wheel fixed on top of it (a common sight in early Land Rover versions), and opening rear board with the IR receiver attached to it. Most of the Land Rovers can be accessed from the back by a single door, and a board is a rarity. I chose the board over door because this way the IR receiver was more exposed, and could be pulled out from the cabin’s inside to some extend if needed. Moreover, the rear part of the cabin has been adapted to house a camera. Due to weak mounting points, this solution worked well only on flat, level surfaces, as proven during the race.

It should be noted that the model’s body was inaccurate: the front radiator grille should be put further back under the bonnet. I couldn’t model it because of the frame that braces the suspension module of the front axle. Moreover, inspired by the Inception movie featuring a tracked Hummer H1, I have created a simple set of four tracks for the Land Rover. The tracks and wheels could be easily swapped in the chassis, and while I did not intend to use the tracks outdoors (our racing rules don’t allow tracked vehicles of any kind), I have used these to drive around my apartment. The general performance was apparently inferior with tracks on, and in particular the traction was much worse than it was with wheels.

The completed model weighed a whopping 2.1 kg until I removed ballasted bricks that were mounted under the bonnet in order to shift the centre of gravity forward. It reduced model’s weight to just below 2 kg, and I decided to leave it like that because there was no time left for changes. The model performed well at this weight, it experienced no mechanical failures and displayed superb traction, but it was obvious that it will be struggling against its own weight.

Land Rover was warmly welcomed by other contestants because of its look and its very short building time. It performed well in the race, no mechanical failures occurred, but its weight turned out to be a real problem. The model ran out of power to climb on several occasions, and toppled over once. It ended up at the last place in the race, much to my disappointment. Yet still, other drivers and viewers were greatly impressed by its look, which led me to believe that it would be a waste to take it apart, and that the model should enter our last 2010 race on October, with open body design that should significantly reduce its weight.

    This is not a kit. It’s my own creation and you can’t buy it, sorry.

  2. January 14th, 2016 at 17:30 | #2

    Found this site randomly. Where do you buy a kit like this? My husband would love to do something like this and is in love with Land Rover Defenders. How do you get started in building these and where can I buy these kits to start? Thanks.

    No need to be sorry, I just think it this is the best solution to your problem 🙂 It’s easy to past photos on EB, and many people will be able to answer you.

    I’m sorry Paul, until now I knew only your website because I build Lego without watching any site. I thank you for your advice and I’ll sign up to Eurobricks.
    Good work for your future projects.

    Time is not the problem, I just don’t see how I can help you. It really all comes down to me designing the suspension for you – which is difficult because of communication and a number of other things. I believe your best option would be to start topic at Eurobricks, for example, where you can post photos of your work and ask for help. Did you try that?

    Paul, I’m a lego builder too, and I have a question for you: I want to build a Lego version of the Land Rover Defender 90, reproducing the real mechanical parts. Particularly I want to build the rigid axle suspension system with differential lock (in front of the car with steering), like the real Defender, not using the indipendent suspension system. I have problems with steering because the axle-shaft reach out and shorten when the wheel turn. I’ve done a lot of experiments and one was successful, but it was bulky. Could you help me ? Which lego pieces have I to use ? (if you have time for my question, can you send me the codes of the pieces I have to use ?).

    P.S.: I asked you the codes because I’ll be able to buy them to bricklink. But do you have an e-mail where I can send you the photos of my work ?

    Cool Land Rover!
    Do you think you could make the Land Rover DC 100 Concept, I wanted to make one but it failed horribly! 🙁

    I really love your car and you did more than a great job! Well done 😉

    Listen, any sort of a lockable differential will make your truck extremely wide, and any gain from a lockable differential will be completely, utterly negligible. These are small, light models we’re talking about, not real life vehicles. People like you typically make their first TrTr vehicle full of fancy stuff like that. Two or three vehicles later they learn that simplicity is the key.

    But with portal axles you could reduce the strain on the diffs and if you managed to fit a M motor Inside the axles you could make ( at least the rear axle ) electrically locked. And if you didn’t lose power to friction in corners ( which gets even more with increasing grip ) your vehicles also might be faster.

  11. Sariel
    April 15th, 2014 at 10:24 | #11

    Most people with no experience in Truck Trial think like you. It changes when you get some experience. Pneumatically lockable diffs are big, complicated and fragile. And a gearbox in TrTr is there to make sure you have more torque when needed, not to make differences in speed.

  12. Ev3fan
    April 15th, 2014 at 09:46 | #12

    Pretty nice vehicle! But i still don’t like the idea to use knob wheels instead of a lockable diff and wasting motor power on friction while turning. If I’d try to build something like this I’d use pneumatically lockable diffs with portal axles.And why do you always use a gearbox in your TT models? I can’t See a real difference at speed in your videos.so to me that would be unnecessary extra weight. I’d use the motor used for shifting in your models for locking the diffs remotely

    Best value for money would be to just use the Bricklink to buy the individual pieces.

    Hello! Inspired by this, I’d like to build a sturdy off-road vehicle as well. I don’t have any of the right pieces to build one though (especially not large off-road wheels). What sets would it be a good idea to buy for useful pieces, that are the best value for money? Thanks! 🙂

    Sorry to hear that. There are plenty of instructions for suspension systems, gearboxes, chassis and building strong, I thought that’s what you need for a 4×4 truck.

    Oh so it works. That’s good. I guess the springs are more flexible than i thought.

  28. Sariel
    February 3rd, 2013 at 01:46 | #28

    It’s a concept you’re not understanding. Build it, and you’ll see how it works.

  29. Zaxash
    February 2nd, 2013 at 22:08 | #29

    I’ve downloaded the instructions for this model’s chassis for ideas and stuff and then realized it looked like the suspension system is completely useless in the front because the shocks can’t tilt at all and aren’t free. If you look at it you might be able to understand what I’m saying. Is it supposed to be like that, of is it a concept I’m not understanding? I’d love it if you could help me. Thanks in advance!

    Am I correct if the suspension parts from the Crawler 9398 (and some others) set could be used to simplify the suspension? Looks like its got similar gearing down on the axles between the wheels and the “differential”

    A brush and water usually suffices.

    I have a little question: how do you usually wash the tires of your trial trucks (if you do it)?

  39. gabry
    August 29th, 2012 at 18:35 | #39

    Really cool! But if you put the battery box in the centre of the car it should have a better stability (sorry for my bad English, I’m italian…)

  40. ghaly
    August 16th, 2012 at 04:23 | #40

    Hi Sariel,
    i have just finished building the rear drive axle of this car and i am really impressed with it.
    i was planning on building the front of it aswell but i cent because i only have 4 of the 2905 peice and i cannot find any other way of building front wheel drive.

    any websites i could look at or ideas?

  51. April 23rd, 2012 at 18:20 | #51

    very good struture although fist time trying it the thing broke not best pleasd

    With all due respect, driving on a carpet has nothing to do with off-road performance. Nothing – not even remotely close. Trust me – been there, done that.

  57. Sariel
    February 25th, 2012 at 14:31 | #57

    I’m not offended, I simply know what differentials do to the off-road performance. They simply kill it. Try and you will see.

  58. master2708
    February 25th, 2012 at 14:29 | #58

    I strongly disagree. Anyway, I didn’t mean to offend you, cause I sincerely admire your work and maybe I’ve exaggerated a little bit my disappointment.

    Keep building 😉

  59. Sariel
    February 25th, 2012 at 09:51 | #59

    To tell you the truth, my rack stays in place, I never glued a thing. And crappy turning without differentials is still way better than getting stuck on every possible obstacle with differentials.

  60. master2708
    February 24th, 2012 at 23:57 | #60

    I have to say that it’s a pretty curious construction, but it has several drawbacks. First of all, because it has no differentials, the turning is crappy as hell. This in turn causes the gear rack change its place, unless glued. What is more, the suspension idea is also hopeless. Therefore, to tell you the truth, I expected something more and I must say, that I’m really disappointed. The only satisfaction I got, was the fact, that I managed to combine this chassis with your 2-speed heavy duty linear gearbox (although controlled manually) and it was fantastic experience for me.

    Best regards master2708
