@jantjeuh. Haha I managed to get four in a bulk buy $60 and a whole bunch of other stuff, couldn't believe my luck. @vliet. Yep those are pretty grippy, small in comparison though

Yeah the old Lego tyres seem to have grippy rubber, the newer types are plasticish.

First of all I am really impressed with this tyre, diameter is about the same as the powerpuller tyre. The tyre is very grippy because of the knobs. Might work well on a crawler, you could go two wide. May not look the part but... Thoughts?

I addapted well to studless, it's stronger and lighter while being smaller aslo. Good on you mate, moving on is not easy, most dark age users struggle.

Ha! it's as simple as it gets, though twas the only type that was accurate and reliable. I'd say they could do with some extra bushes on the inside for good measure, but no they never fell off my other test vehicles before this one. I need a single cell charger or a charger that does it all! (expensive) I used up all the juice they had out of the box, so cannot show you right now

7.4v they are lipos each cell is 3.7v

Yeah silly PF stuff, has no range and you can't slow accel or stage steer the thing. I think we should start some sort of petition to lego. You have damaged legs? Sorry to hear that man... We could send in a pic of you to lego as the poster for our demands . But in future please do not roll the 41999

Say hello to my little friend! Montana. Montana is my 2013 hillclimb car set to destroy the course come Christmas. Montana features a bumper which can skid over things or take direct impacts no worries. He is a very simple littler car weighing in at 700g. The super short wheel base allows him to tackle the very sharp corners! Weight is kept as low as possible by use of two lipo batteries, which weigh 20g each. With his beady little eyes on the prize Montana is set to dominate any other Lego RC car out there!

What about that shock that comes with the RC racers, quite expensive piece.

Ha just out of the blue, another reason why I think they have gear reduction is because of the melting axles issue. I had this issue when using a non lego motor, the axle went smooth and smelt NICEEE Also what if kids got their fingers pinched in the cogs, ouch!.. Well it could happen anyway, but it would be more painful.

Lego crawlers don't need dampers, they only need springs to keep the body center of the suspension when on a flat surface, dampers would just slow the bounding and rebounding of the piston, heck if the axles and tyres are heavier than the body than the body centering doesn't even matter anyway . The Lego chassis and tyres act as a damper in any lego model, so fast cars don't need em either. Though I still like to see all the shocks and stuff, even if there is no point to them working model ya know. Yeah and the wheel needs to have a down stroke and a up stroke from center, so the chassis doesn't drop into any pot holes or so the tyres don't leave the ground say if it got a bit of air on a small jump/bump.

Yes I mentioned those u joints above haha, ends up you witle down to a very simple system. Awesome bumper and accurate steering becomes the main concern, and low weight for handling and crash control.

The rubber pieces that hold it together are cool and definatly have other uses, the shocks are actual shocks! Not just springs, they are worth a mint. This thing is very fast and capable, super fun.

Hmmm it keeps saying "you are not allowed to use that image extension" when I try to post...

Update: Ok I have built my hill climb car 'The Lobster" and the suspension is strong, the only thing that falls off the car in crashes is the bumper, which is designed to take impact. My small lipos have still not arrived... So just been using some rechargeables... They suck! This is a 3 wheeler or inverted trike, with only two buggy motors, 4 motors with two units was hard to stop and the weight helped to destroy the car. I use 3 wheels for a heap of reasons, less rolling friction, less weight, the rear wheel being bared from either side. Suspension conclusion is a medium no! It doesn't work as it should, probably because there are no actual dampers/shocks to stop the spring oscillation haha so any bump it hits the chassis has to absorb, which makes it bounce around anyway. Haha maybe not that bad! But ya know... Car is heavier, steering is less accurate because of all the play. I have no idea how to post pictures?..

Really nice man, really nice. I'll tell you right now that uni joints don't like high rpm aswell as a lot of force to move a lot of weight, try to keep it at no more than 800g, also this is a good rule to reduce the seriousness of crashing. I use lipos because they are very light and two buggy motors, but going with other rc unit may bring costs down. The bumper is very important, I use a bounce type but a skid type would be better.

@bricktrain haha I hope your not the one on trademe trying to sell it for 700nzd! Might be waiting awhile...

Retro meaning 80s or older? Not to sure what it will mimic exactly. I kinda like it as it is, looks done. Perfect example of a ladder chassis in model form.

Please post instructions for this once done, looks mad! I love the live axle at the back. Though those tyres look too wide for an older race car, could be wrong.

I am struggling to see how that can dig a hole... I actually like the bits you have stuck to it, they appeal to my rogue, down with the government nature.

I'd love to see it. I would like a tough suspension system that uses these wheels http://www.bricklink.com/catalogItem.asp?P=86652c01 wheels, I love the balance of these wheels and weight.

The car was running at 11v there, the wheel spin is nice but I don't like that axle tramping, sounds horrible.

This! One of the best Ideas I have heard in a while.

Update: The new suspension that I have come up with is very tough. Pros - It can easily handle direct small to medium crashes on the control arms and tyres. - It is compact for it's scale. - It is attractive. - The steering is like a one way valve, so the shock won't get fully transmitted to the steering servo. Cons - Hardly any turning angle, rely s on throttle steer technique. - Big tyres are needed because of ground clearance, big heavy tyres. - Ok amount of travel, doesn't allow for pot holes. I will post pictures sometime tomorrow of how I did the wheel carrier using the crawler hub and how it is possible to get a close pivot point, almost in the wheel. Here is a link to a video of me testing volts and toughness of the setup. I use a power supply to simulate different battery configs, the buggy unit is a test unit the steering is broken and it stutters at low voltage so please don't feel to sorry for it. Please if you are a mature person and believe that lego is more precious than your first born son do not watch this video.
