Dito @Jim When does the voting close? I think it's so close for second place :D On a side note: Are the participants required to vote? As they can't vote for their own entries, it's like a disadvantage to vote (for others) or am I wrong?

This could be used as a demonstration for what can be done with intelligent programming. It really is an automation designers dream! Great work!

I am really not a car guy, but this thing looks really good. I am a bit concerned about the stability, looking at the part in front of the cockpit, right behind front wheels (2nd pic).

I just looked at the entries, there were so many amazing builds back then, mindblown! Or a weight limit? :D

What a great idea! Also useful for checking of the functions. But that could result in too much entries :D In my opionion, could be be easily a contest with the most competitors so far. @Jim If you settle for this contest, we definetely have to vote at least with the newer formula 1 theme as I expect many great entries.

Polybag! Polybag! - maximum 75 pieces - All parts have to fit in a zip bag 15x15 cm

That was the catch for me, but according the rules there are many ways to interpret them, quoting the first page: "Create a vehicle that transforms into something else like another type of vehicle, robot, object" :-)

They already did... https://buwizz.com/de/shop/buwizz-3-0-pro/ Really expensive, but so useful! The app is self-explanatory and waaay better than the Lego Control+ app imho.

6: 10 3: 6 1: 4 5: 3 4: 2 2: 1

@leonema Dumb question, I know, but did you activate Bluetooth?

Ok I was wrong, they did the front overhang pretty well. The rear seems too short, but could be so because of the perspective.

*without a worm gear-driven shield

What a cool little set! The two functions are great for this size and the looks are spot-on, blue seats ftw! :D Did you try to exchange the 16T gears with the red ones with pin holes?

Actually, this is the first control+ "speedy" set which price tag seems ok, at least in contrast to the other sets: 42140: 130€ 772 pieces 2 L-motors 42109: 130€ 463 pieces 1 L- and 1 XL-motor 42124: 130€ 374 pieces 2 L-motors

The mini Xerion has more complex steering AND a PTO driven by the rear axle. So more functionality than this :D

The shocks are to achieve the bi-stable mechanism. Seems like only the front cabin part flips. The rear part with battery box and motors is fixed to the chassis with tracks. *Edit: Zerobricks was faster :D

As the TC21 is near its end, are there already favorite topics for a new contest? The "shrink-the-model-contest" idea is one of my favorites besides the PF/PU-contest with autonomous vehicle, and some restriction according to the amount of parts of the original model helps too. I'd even go for 850 pieces of the original model, so the 8460 could be included :D Also maybe a restriction to use half the parts or less of the original? On a side note: @Jim Are you planning to do 1 contest per year as we are now catching up with the numbering of the contests with the year (TC22 in 2022)? Maybe the reason for the little number of contestants on TC21 could be the sheer number of contests in former years. If we'd have more time on our hands an really think about a model, it would be better: quality > quantity. Also there would be a little more anticipation and the contest really becomes a special at the end of the year.

Such compact gearboxes are beautiful, props that it worked out! :-) As I didn't read it out of the text: What is this truck transformating to?

As these wheels are also used for a city tractor set, I actually think that this set is completely useless as technic. It actually could be a way better looking City set with the same functions and no cut-offs at all. I mean these archs would fit perfectly as mudguards:

Okay, after seeing this, I am dissapointed. For the right side, the usage of a panel is mildly acceptable, but for the left side, the solution with a sticker as a ladder is totally off. Also, the front is one stud too short. The yellow trailer is completely wrong for a heavy puller but ok for a play set. Imho both @Jurss Xerion and @SaperPL Fastrac are way better builts at that scale.

Look at the side mounted panels 5/6: I guess it is the first set where you have to put a sticker on both sides of a panel :D

Dito. This one is really well build. The turntable for the connection of the rear axles for example. Same goes for little details like the brake lever. This would be a minor bummer if its really the crank...

Thanks guys :-) I am not completely satisfied with the model cause I didn't achieve the self-stabilizing action while transformation, but I hope the story about the rollator made up for it ;D

Ivo Robić Old little soviet tractor, kindly named Ivo Robić, had a hard life... Pulling heavy equipment his whole life, our dear Ivo needs a rollator now to sustain stability. Enjoying a sip of self-distilled Diesel here and there, he is wobbling home afterwards. Never been the quickest one, he has to move even slower in his old days, gone are the the years of high mobility. He is driven by an angular M-motor, the transformation action is done by a PU L-motor. Source is a Buwizz3, giving him mild glowing blue eyes.

Finally the parts arrived in time and I could finish this model. I actually didn't managed that it stands on its own with the front axle attached and the mechanism to spread out the front wheels as arms was way to unstable. Therefor our dear Ivo needs a rollator in his old years...
