Seasider

Remember there are ice sheets and not just soft powder snow. And TLG themselves have done walkers and unusual vehicles for their arctic theme

You’re welcome to the Stud.io file once I’ve finished it. The reason I used worn gears is that the 3D printed model I found on YouTube used a single worm thread to drive all the legs via a single motor. The other advantage with using a worm gear as the drive is it then locks the legs in place securely. The hardest part is making sure you react the loads from the legs into the body.

That’s an impressive model, and great how the 2 vehicles link. But a shame it’s not very smooth in the large vehicle, it kind of makes the smaller model the main model. I think to fit the theme better a splash of red and yellow would really lift this model further. Otherwise very impressive

I’ve switched off from Sariels reviews. I find him too negative about sets and in my opinion doesn’t give a balanced view or a view that considers the main customer (not the vast majority of us). I far prefer RacingBrick ( @kbalage ) or Jang these days. These pull back models have a place, my nephew loves all the monster truck ones.

Glad you’re doing an entry. The fact I had a figure and some skis led to my colour choices too. Looking forward to how this turns out. Don’t forget a splash of red and yellow

Glad someone else has gone unusual in terms of method of movement too. I think the biggest challenge will be keeping your central bit level as it drives as you’re normally reliant of the weight counteracting the drive of the wheel. Good Luck

So how is everyone getting along with their builds? I’m assuming/hoping that people are just being secretive (never understood this) about their builds and going to release a “WIP” thread at the last minute.

Looks like a good start… not sure if a porpoise would like being towed on purpose though. Would suggest a sling/cradle for Porpoise carrying, perhaps on a crane arm of a arm like a skip lorry

Nice review there. I think the biggest shame is the scale difference to the tractor. The tyres and lack of grilles wouldn’t be a concern to a kid, as they just wouldn’t be aware.

I thought about adding discs as feet but I think it’ll spoil the look. Perhaps it’s just for exploring the frozen ice shelves and not fresh snow areas

Not too sure about the headlights (but then they’re from the original model), but your overall design and technic on this is great. Definitely a track day beast

So I’m pretty much done. thanks to @msk6003 I built this … I added some bits to mean it can only moved the switch in one direction to stop me flicking the switch too far meaning the lights stay on. Then I worked on mounting this and the tailgate mechanism. But the light mech was too long for the space I had left so as you’ll notice the IR Receivers have moved forward in the vehicle to free up some space. This meant taking the whole thing apart to move the main drive motors 1 leg forward. Thankfully I build this in a modular fashion so it was easy to take apart and update. And now it’s all back together and resting on a “work stand” I also made to help with assembly. Just a few System pieces left to tidy a couple of areas and that’s it. I’ve also been working on a Stud.io file to go with this, as I try to do with all my builds. But that’s missing the legs at the moment so no pictures at the moment from that. Controller is quite easy … Yellow Left = Left Legs Black = Tailgate Red = Lights Yellow Right = Right Legs Proper pics and video to come once I’ve added the system bits. I’ll have to work out where to take them, we don’t get snow around Christmas here so I think it’ll indoor shots.

I’d say build to whatever scale you want. A small neat model with lots of functions can be way more impressive than a large model with lots of space for functions

I can’t wait for the day I have to decide do I swoosh my Ornithopter or my VTOL … and I’m not joking. Im a big space fan in general (not just Lego) so to get such an influx of space stuff is great for me. I also like that these are all original models and not licenced sets. Sets in my pre-dark ages weren’t licenced so I’m glad for this. Good to see some creativity

Having just watched @kbalage’s YouTube video I can just picture TLG employees swooshing this VTOL and the Dune Ornithopter around the design office together. Genuinely impressed with the size of this, didn’t picture it as big as it is

I think going multi-hull or pontoons would be strange for an icebreaker. I agree with others you need to bring down the centre of gravity on your model, it looks very vertical. thanks for the link about the propulsion method, very interesting, I can understand why in scenarios when you need ultimate manoeuvreability it works well. All the tugs I’ve see in use have been traditional props.

With the wheel size to body ratio it reminds me a little of the Antarctic Snow Cruiser.

So I’ve been having some very good build time on this and it’s almost complete. First of all I played with the legs and their sequence. My model up to this point had legs 1&3 at 180 degrees on the large gear to legs 2&4. But as @1gor pointed out it rocked back and forth a lot. I then tried each leg using the drive gear at 90deg to the next which turned out to be even worse. It turned out the answer had been staring me in the face the whole time (as the model I used as inspiration from YouTube uses the pairings of inside and outside, so 1&4 and 2&3 with 180deg difference on the drive gear. It’s much smoother. So what does the model look like … I’ve got a cockpit I’m happy with … Most of the electrics worked out … And even done some finishing touches to borrow from the old Arctic theme (because by pure chance I bought an old technic set from a market and it actually had 3 inside the box, one being 8620 which gave me the figure and skis!) But still some things to do … 1. Mount the linear actuator for the rear door. I’ve got the position sorted, just not mounted it yet. 2. Shorted the legs so they don’t stick above the joint. If you look you’ll see the leg design has changed where I’ve made the cranked liftarms to be the middle section, not the final section. This gave me better ground clearance but all the final beams are 2 studs too long at present. 3. Await a Bricklink order to correct some parts currently in the wrong colour. 4. Create some classic Arctic Technic stickers. But a question … it there any way to make lights switch on/off using PF without just holding the switch in place? Enjoy

Interesting boat, never seen that type of propulsion before. Remember this is a technic competition so I’d avoid making a ship superstructure from too many System parts

That’s a great entry. Very compact and cute little snowcat.

Ok another question I want to stop an axle from pulling out under load, what’s better a single bush or 2 half width bushes?

A quick and easy one clutch gear (old style) if I want to have a motor connected to a shaft that may lock and I want to put a clutch gear in between to prevent motor damage should I put it motor side or output side of the 2 gears ?

Just seen @kbalage’s video. I didn’t realise the Space theme also fed across to DUPLO. So the whole family can be involved.

And the Friends set too has the same Orange connector so you could connect Technic to City to Friends so all the family could build together

@Jim have you seen 42605 the Mars Space Base and Rocket. It’s got the classic space logo and looks coherent with the City Space stuff … but no Friends sets for me.
