I have only built 42042 and half of 8110 in my AFOL year so is this slop on the rack and cog setup normal? if so does everyone just put up with?

Nice work, I feel a 'how high can you make your fountain go' competition coming on

A bit more progress. But on the portal hub axle setup. I have slow steering hooked up without an LA. I used the rack and cog. It works really well, but there is slop in the rack so the wheels can bump steer a little still :( the LA's stoped that happening. But there are compromises maybe if I can't get rid of the slop as the turning circle now is so good that I will stick to the portal hubs. It's not Ackerman but I have toe out to help tight turning. A few other small problems like if I oversteer the worm gear setup lifts off the following gear so you can't steer anymore. Suspension travel is quite well balanced. Soft and good travel when one side is compressed but quite firm when both shocks and compressed holding the weight of the vehicle.

Hello! I usually hang out in the Technic forum not contributing a great deal, so I thought I would try a bit of non technic for the first time in my AFOL'dom. so here is a small crabbing boat for a single person operation. I'll post the pictures instead of dribbling on too much as I find myself getting more boring the more I say. hope you enjoy and any comments good or constructive greatly received.

It looks good but I would like to understand better how the boom extends as I can't see how at the moment. How have you linked the 4W steering? video? more details please?

Well I think I know what you mean. I thought maybe you were going to say [WIP]trial truck axle. Getting better. Oh well... I may have a lead on the steering which is really my only annoyance. I've been putting the portal axle back together and hooked up ackerman steering on top which is pretty capable of LA operation on the front so I should be able to transfer this over to the other axle. I know all this axle stuff may be trivial for you lot but I'm finding that I can make an axle easy and look good, but it won't operate properly. Hopefully getting there though.

that looks alright! have you tested it in vehicle? I'm actually kinda happy with the axle i have its getting quite structurally robust with minimal parts its just the steering that I cant enjoy, as the rack and pinion setup is so loose and as its 5 studs above the hub connecting points it makes it even more loose with the 'leaning' tolerance at steering lock. i could gear it so the rack sits lower but then the more gears in pace the looser it will be. I'm now trying to fit the LA at the front of the axle for steering and settling for a small bit of toe out but getting a small amount of toe out from the front side of the axle seems hard. never try to design an axle to fit a chassis. oh, and I hope you can all accept that I put avocado in my fruit salad.

really appreciate all these reviews and the effort that goes into them. I may get this solely for the B model, it looks great. there must be a sea plane airport somewhere huh... thanks for focusing on the steering linkage too as that may help me in what I'm currently doing (trying).

Thanks for the input, suffocation and horcikdesigns. I think this firmly seals the coffin on this axle (I learnt to spell) it's a light vehicle but probably not that light. maybe I'll go finish that one man crabbing boat that has no technical functions...

Thanks Imanol bb. swapping cogs will happen! It's a low priority at the moment I'm not sure about crab steer, kiwi but you are right that locked diffs and 4wd are not a friend of tight turning circles. This is a new steering setup with Ackerman. It had a real tight turning circle. But so tight the hubs won't turn with those 2 pin CV type shafts! A: my expectations of Lego mechanicals are too high. B: I'm useless.

I'm putting this up as a WIP as I must be the worst axel maker! this so far has been maybe 20 hours or more, over the last couple months so any tips or pointers greatly received. im trying to make an axel for my very modified MOG... ...that has good turning circle, slow precise steering, maybe a manual diff lock if there is space and suspension that somewhat resembles real movement. By that I mean if one wheel goes over an object, that shock absorber will compress leaving the vehicle chassis mostly unmoved. After the PNEUnimog...although it worked somewhat as a trial truck (it went over stuff) I may as well have had lift arm suspension and the steering was total understeer from the portal axels scrub radius (if that's what it's called) So I am trying CLAAS hubs instead of portal hubs to try limit scrub radius. I've built the portal axel double height cog bit solid into the axel for more ground clearance. I've spent ages trying to develop Ackerman steering. I think I have it. Or at least the result of it but how the heck do I operate it. I am trying to hook up smal LA for slower steering. Although I would like 4WS and LAs can easily go out of sinc if there is 2. I feel like I'm being over pedantic to try and get the perfect axel. But that's my project and I can't seem to move on until I'm happy. What has annoyed me and prompted this WIP is that I was testing the Ackerman setup with only RWD hooked up and it turned in 1200mm but with 4WD it was 3 times that on a solid surface house floor. WTH! Maybe it will be different on loose surface. This is the template I have so far.

Great work! Im a big fan of fishing boats especially so most of your models are right up my alley. It's great to hear people can make some money from this.

who am i to criticise, but i feel this is bordering on being a excellent C model, if only for the small visual let down of no gap behind the cabin and the lack of height of the rear panel area which should be close to the roof line of cabin. otherwise I look forward to the video!

Love it if it's accurate. but I think it should have a GBC fitted to it to count the meters in balls instead of what you have

I Am spending an immense amount of my limited free time rebuilding my unimog to be a great trial truck crawler and have stuffed around with different shocks and trying a thousand ways to fit them for best crawlability, and it now seems that I have totally wasted my time after seeing this awesome build.

Yes that's it thanks. I was just really interested in the real world difference to calculated to see the affects of aerodynamics, rolling resistance etc.

I am not usually Interested in massive builds but the BWE is one machine that deserves one and like others have said yours is epic! I love all the minifigs to 'play' with and the control panel is a Lego nerds paradise! It deserves a complex operating panel, if it was to easy to play with that would diminish the experience.

Ok so that's pretty cool but it looks like it accelerates off the line quite quickly as well. Does that mean you could gear it up a little more for more top speed or have you tried and what you have is the limit before the 'tipping point' of no acceleration? EDIT: actually I think my question is more like What is the calculated rpm of the drive wheel so I can know the difference to the actual on track rpm at 35kmh. Thanks!

Not sure what happend to this challenge, hope letsbuild is ok. my PNEUnimog was a bit of a flop to be honest even though I entered it. Here is the vid. Currently undergoing sbrick or buwizz upgrade with single motor drive and chassis and suspension upgrades and getting rid of these woeful pneumatic controls! we have similar music tastes @JTS

comment unworthy

Love a good quality video,

good post. I agree. Thinking about it, what I posted before is a bit too 'calculated' on the results. what you say, @Aventador2004 leaves variables and thus decisions for the voters which is far more exciting and inclusive. just like the bot battle comp.

Too many cooks spoil the broth! Haha! Even I'm adding salt! Thanks for the pole @Zero (Zblj) Regardless of the building rules, on the testing track side of things my thoughts are, that there should be a test for high speed timed over a defined short distance averaged over both ways, one for axceleration timed over the same defined distance averaged both ways, and if people want handling tested, just a circle of defined size, how many laps in a minute for example. This would be the best way to have a satellite competition that isn't a pseudo competition. i just thought, maybe these rules will be ready for AMS-2 next year.

I know this is just discussion but there are so many ideas floating around that to me it seems the actual end point of the challenge has been overshadowed by the details, and that i'm not sure what the actual challenge would be. is it a: an overall car with no specific test for it B: a car that handles well ( but how is that tested) C: a car that has certain attributes but that the highest speed it the accomplishment? D:other I think the final outcome is required first to know how to then define the details? perhaps we need to state our preference for the outcome first? or maybe i need to work on my understanding skills haha!

I like this a lot. i have missed this topic somehow so will now read the 5 pages with my next cup of tea!
