One thing that might prove my “hunch”: the Alvis. Same wheels, same suspension without gear reduction in hubs, but different axle setup: first and second axles steered. I remember you had problems with it turning, but wasn’t that for some other reason? A failing drivetrain?
Anyway, it’s too bad the BMR groun its gears, the look of the vehicle is awesome.

The axle twisted?!!? Damn! I thought I’m seeing it wrong.. sorry for that BMR. I have a feeling that another thing that makes it turn difficultly is that the first and last axles are steered. I can’t really explain it, it’s just a “hunch”. I might be wrong. Don’t get totally discouraged from TrTr, though. Simpler vehicles like the Jeep worked quite good, and I’m sure your vehicles are interesting types in the race. And strangely, the u-joints survived?

with the rusich are you going to build the tank first, or build them at the same time?

Good luck, good luck! 🙂

@Sariel
It was just my opinion, but let’s keep fingers crossed. 🙂

@Sariel Nice 🙂 any heavy components left to mount? Or just tiles to cover the body?
I seriously think this is going to prove good in the race. Gearbox worked good, suspension worked for the Alvis, drivetrain is without diffs – and the center of gravity is also I guess lower than with the Alvis.

@Sariel I see. Seems to e that this APC is going to have a low center of gravity, the bodywork isn’t too high-built. Did you manage to mount the drive and steering motors low in the chassis?

@Sariel
thanks. Sorry I mixed them up. I guess the RC motors are more likely to keep that RPM: they’re stronger, and there is no gear acceleration like in the previous vessel.

The BMR looks cool, did you say that the middle suspension will be softer? Is it because the vehicle “sits” on the top of a hill and the other wheels can touch the ground, so the APC won’t fall forward or back?

With 1:1 gear ratio, what’s the RPM of the propellers in the “engine block” of the boat?
What was the RPM with the Trimaran?

Please build a North American P51 Mustang, a Supermarine Spitfire, a Curtis C40N or a Hawker Hurrican. That are realy nice planes in 2nd Worldwar.

no, thats not what i meant XD do not go back to the rubicon or land rover, i meant built a new model type@Sariel

sariel, you’ve seen all the new parts coming with the lego technic unimog u400 8110 right?? it would be awesome to see u create a new landrover or jeep with the new portal hubs!

@Sariel
😀 😀 😀 true. It looks like as if a container on a trailer slided forward when braking too hard. But this doesn’t mean I’m not curious about it. I’m gonna be waiting for it just like for the other models.
Maybe Russian trucks are so attractive to many because they’re so ugly that you can say they’re bordering on beautiful. 😀
Does this truck have identical steering angles on both front axles? Is this a standard for tank transporters? Gives better off-road performance?

As i don’t know how to resond on your last facebook note, ill just respond here. You’re currently looking fir oshkosh like trucks. I think you should build a Daf tank transporter. Why, because cab over trucks look great and you haven’t build them yet if im right. Besides that there is a great symbilism for the dutch. Not only dutch daf, but the government has just decided that all tanks will be sold. Drivinh a lego daf, carrying a leopard away, thus would look great.
By the way, the daf’s that the dutch army uses are not meak road haulers, but have serious off road capabilities. Don’t forget that the paris dakar and offroad ginafs are based on dafs.

@Sariel will it be used in trtr?

Man, it sure is one ugly truck.. 😀 not that the MAZ is more beautiful… is it 8x8x4?

@Sariel
I don’t have Facebook 🙂 my only activity realting to it is following what you’re up to, but I don’t want to deal more with Facebook. Anyhow, after posting the comment I read that you decided on this truck. Every function, including the trailer will be remotely controlled? Are you thinking of using pneumatics for the trailer so that no long shaft lowering the back deck is needed?

Hi!
For the 8×8 tank transporter project, I’d say something similar to the MAZ (in the lower picture?) would be better, as the body is not only over the front axle like the Oshkosh (upper pic), so can more easily accomodate the drivetrain closer to the rear axles. Just an idea.. 🙂
Would a Tatra be out of the picture? 🙂

in any time in your future projects could you try to make either a leopard2a6/7 or a tiger tank

will the monorail: siege cannon fire?

sorry, brick shelf

ok, is it on your bricklink?

have you ever considered building a techball vehicle?

@Mike
and that integrating battery boxes, motors and gears would be a nightmare… 😛

@Sariel
well yes, you can reinforce a studfull chassis with plates to prevent bending.. and I guess with the Lambo you can more easily make the roof a structural element; hardtops are always more rigid than convertibles. Still, you cannot doubt that a spaceframe of liftarms would be kind of a state of the art way of building a supercar 😀

One more thing: in the description to the Monster Truck, please touch on the modifications you made, what was wrong, what was replaced, I’d be really interested in the evolution of the truck also, in addition to its final specifications. Thanks!

I mean that would be almost bordering on “engineering”, but if it is possible it’d be kind of a breakthrough.

I hope you’re going to make an attempt at the Reventón soon 🙂
I was thinking about this: a flat chassis may not be the best solution: you’d have to make it very heavy if you want it to be rigid, the Dodge proved that. It would be much more difficult to build, to plan, but a three-dimensional frame that is light but rigid would be better, made of liftarms connected to each other.
Now I knowthis seems weird at first, but maybe the best solution would be to have such a frame and ven use parts of the “body” to carry the weight of the car and be part of the structure itself. Which is difficult with panels.. but maybe not impossible.
Do you think this is possible without spending a year on building?? 😀 😀 just a weird idea…

You should make a German Maus

did you canceled to make monster truck

then ALL THE BEST OF LUCK!!! :))
I like that locomotive.. powered by a monstrous V4 :))

are you still going for remote-controlled ground clearance for the bmr2?

Are you going to make some equipments for the tractor when you are building it?

the monster truck is coming soon because monster truck is not in future projects. is i am right?

@Sariel
i have bulid one but it is not so good

just had a thought, what about tilting the front axle back slightly like this:http://www.mocpages.com/moc.php/226735
it would make it easier to climb over stuff?

WHEN IS THE “MONSTER TRUCK” COMING OUT?

please email me i need your help with the jeep and if not i am willing to pay alot of money for that jeep

Hello i love your website ! And all your projects !
Could you make the cars of the legendary group b? (like the Peugeot 205 t16 or audi quattro …)
Sorry for my English !

just had another look smyk and TT both have fully functioning prototypes!

i am beginning to see more and more trucks ,for the first 2011 race, on brickshelf. make sure you build quickly ATR, emilus and maniekmaniek have all started building their trucks…

@Sariel
they seem stronger than u-joints 🙂 with a driving axle from diff to wheel you get significantly less backlash than with 2 u-joints, I guess. Hm, do you think such a setup would be useful in a trial vehicle? Like in the BMR2, which I speculate will have an independent suspension setup.
That’s gonna be some testing… 😀 for the new parts 🙂

@Sariel I guess so… I think i saw cv jlints for some 5 dollars or so.. I can imagine the price of these.. but it’s interesting to see hoe Technic suspension stuff evolves. Compare the rear suspension of the old red Supercar, and this new 8070…
it’s cool to have new specific parts but it’s fun when you try to put something together from a lot of parts, like a rear suspension using standard pieces.. 🙂
Are you planning on getting 8070, or these joints?

@Sariel XD could be… then it’s gonna be massive, especially if you gear the driveshaft down a lot. CV joints must be stronger than u-joints I guess.
Have you seen that in the (8070?) new supercar there are some new (?) pieces? Kinda like the “negatives” of cv-joints, with a 2 studs axle on one end I think.

@Sariel that was my supposition too, but then I just don’t get it how u-joints at wheels come into the picture, especially because you don’t use them if they are not especially necessary.. this puzzles me. It doesn’t matter, I’ll see it when it’s ready but I can’t get over this 🙂
please take good close-ups of the suspension once you’re at the photo session! 😀

@Sariel I thought (must’ve seen it wrong) you use the cv joints with the off-roader set’s suspension arms. Whatever 😀 I’ll see it later on 🙂

@Sariel good news! 😀 wow can’t wait for that monster truck!
U-joints are only used in driveshafts right? Not from diff to wheels (any diffs? :))

@Sariel 🙂 question: why are the gears replaced by rubber bands on the MT’s axles? I thought you don’t much like to use bands, doy ou need the slip for some reason? No room for clutch gears?

Do you think it’d be a good idea to include your new gearbox in the monster truck? It could be “fast” while it could have loads of power to climb over… stuff.

im looking froward to seeing the monster truck

will the monster truck be like grazi’s bigfoot? http://www.brickshelf.com/cgi-bin/gallery.cgi?f=26044
and will it be based on a real life monster jam truck?

Yes, finally a proffesional building a ‘motorised’ monster truck. I couldn’t find any of these on youtube, so i have zulch inspiration and ideas as i have been wanting to make my own for a long while. So, are you making it fast or just to show of suspension?????

Thx verry much for this. I find it amazing how you can come with both elegant and simple answers to the most complex problems.

Hello Sariel.

Greetings from Switzerland. I really love all your creations and I admire your talent to developp sound technical solutions applied to LEGO. And I may steal some ideas from you in my future MOCS. I will try not to forget to credit you thaught…
I’m in building Si-Fi MOCS and in each creation I try to add new power fonctions and make it more and more complex but also minifig scaled, realistic and with a sound and thaught structure.
Last year I have finished the droppship from Aliens and this year I’m building a military cargo ship with around 12 motors and tons of power fonctions which is going smoothly.
But I’m also developping a Star Trek inspired corvette and I wonder if you have already developed PF weaponnery. I’m not so strong with this and basically I’m looking for a “weapon marchant” who would allow me to integrate PF working weapons (such as missile thrower) in my creations.
Let me know if you are interested in such collaboration.

Steve Emmenegger

Sariel, could you (or will you, later on?) provide a photo of the Humvee’s front axle from behind? I’m curious how you set up the knob wheels at an angle as you said before. Thanks!

Sariel,

I was just going to ask when do you think you may have the Land Rover instructions done. I just want to see how you run the power to the front wheels through the turntable. Thanks.

@Sariel Oh ok. What I meant to suggest was a system that is used in hybrids, e.g. Prius, or the Chevrolet Volt: they drive different parts of a planetary gear with the petrol and electric motors. For this adder the inputs are the two axles, and the case of the differential is the output. The systems I meant are a wee bit more complicated, but I guess it’s hard to model those, because you can’t really make a planetary gear system other than a differential with Lego…
You can build a planetary setup, you just can’t drive the outer ring, the casing, nor the inner ring that holds the planet gears.. so yeah, I guess this remains an idea.. 🙂

and if the small bevel gears would take the load.. hmm..

I just thought, would it be possible to make a.. kinda gearbox it would be, similar to that of the Toyota Prius: a planetary gear that adds together the electric and gas motor’s power. Maybe it could couple a medium and xl or any other motor, so that if you drive different parts of the planetary system with the different motors, you can add extra power and speed by simply turning on another motor, especially with the speed control function.
Damn if I had pf stuff i’d give it a try 😀 can you consider this as a kind of CVT transmission? Not strictly speaking, I guess. It could be useful in supercars; maybe it would be better than a gearbox, but this is just an idea, dunno if it’s worth any experimenting..

Then make the new batmobile

what about making the batmobile – not the tumbler, the classic 1980s batmobile.
it’s got loads of functions and would be a challenge?
