Thanks! Looking forward to seeing your photos. The instructions (photo teardown) are 1-2 weeks away. Expect a fairly difficult build - but it will be free, at least! Thanks! Glad you like it. One of the things I like most about Technic compared to System is how much you can do with a relatively narrow parts selection. I don’t have a formal MechE background, but my current work as a quality engineer touches on some mechanical ideas every now and then. Mostly Technic is an opportunity to be an amateur mechanical engineer, which has been a hobby for a long time. Thanks very much!

Congrats, everybody - so many great entries! I guess it’s good there was a jury voting round, because even though I recognize Samolot’s 8462 redux is probably less “true to the original” than the winners, it was too darn cool not to vote for it. Even though some entries got penalized in this way, I think it would have been a shame if the entries in question hadn’t turned out the way they did. Both inside and outside the scope of this contest, there are some great accomplishments here!

Thanks very much! Yes, I think the swashplate idea is perhaps the only innovation here that might transfer well to other MOCs. It seems like most helicopter MOCs I’ve seen started designing the swashplate with a turntable and then work from there, which can be restrictive. Of course my approach certainly had its limitations, too. Thank you! This helicopter owes a huge debt to your AH-77 Hunter. From what I’ve seen, your system for cyclic/collective mixing is the most elegant one out there. Thanks so much for making your work free! Once I’ve finished the free instructions for this model, my hope is they’ll help make fully-featured helicopter MOCs even more accessible. Maybe that’ll encourage some Technic innovation in this space, too. Me too - the only option was white, but it was too boxy & certainly called attention to itself in that color. It’s fairly consistent with 9396, I guess. The silver lining is that the push-pull linkage movements can easily be seen in operation

Well done - creative motor placement, and the performance looks great, too! I love how the original DNA of the sets is still very much intact. Thanks for providing the free instructions!

Nice work! Impressive work on the geartrains, and through the turntable, no less - the movements are very responsive! It’s satisfying to watch.

Great job, everyone - it was very difficult to narrow the entries down! 17: 10 19: 6 27: 4 30: 3 22: 2 20: 1

Sounds cool, looking forward to it! A guy can dream…

Very cool video! Satisfyingly smooth operation. For me, 8416 inspired a few creative ways to do beam guiding, without needing a gear rack - here are some screenshots from my forklift MOC (ForelockMocs is to thank for the great instructions). I bet the setup below could be modified easily enough to fit one more stage within the same dimensions. Might add to my list of projects

Not sure what can be done about that first problem, especially for the free lift cylinder. But for the second problem, I’ve had success using beams as the guide. (My forklift is posted on here somewhere). My mast design was heavily inspired by set 8416, although I did extend its overall reach and made it all connected/activated by a single string. There’s certainly some slop when the mast is fully extended, but it’s good enough for me. This beam-guide solution doesn’t scale easily for a many-stage mast, but 8416 suggests a lot of creative ways around this.

Very cool! I’ve always been interested in trying to MOC a proper pneumatic forklift. Your parts are well-chosen here; looks and functions are great, especially for a B-model. I like how you’ve increased the mast extension using the rope. I wonder if the mast extension could be even more increased, if the same string were looped a couple more times on a few more rollers - including one at the base of the mast section, I think. Of course, that would require a serious rebuild of the mast, but I guess real-life masts are fairly modular

Great work! The functions are even more impressive on video, and the new a-pillars are a big improvement. Thanks for making instructions, too!

Personally I think your feature set is amazing - definitely the most impressive collection of innovative functions that I’ve yet seen in this contest. The ejection function is fantastic, and a lot more exciting than a differential. I’m amazed you were able to pack all these creative functions in such a small space! I like the current front grille - and while it might not be completely in the spirit of the contest, I think the rest of the Technic awesomeness more than makes up for it. I think the bodywork overall is as good as it can be given Lego’s limitations - except maybe the A-pillars. Honestly I think since the grille already uses system bricks, might as well double down and find a more attractive system solution. That said, the curves that you’ve already achieved on the rest of the body are more convincing than the System model in my opinion, so great job!

Wow - well done! I wasn’t aware of this B-model until your post, but it’s a great choice. The linkage that you found for the pump is superb. Thank you for walking us through the internals!

Whoa, for me this is basically my ideal tow truck. Perfect adaptation & evolution of the original. Glad you added outriggers - for me that’s the main thing missing from the original. They do look like they could use another plate’s worth of length, though. Still - gorgeous from the outside, and feature-packed on the inside. The working steering wheel, suspension, and drivetrain are the cherries-on-top. Great work, and thanks for the awesome video!

Thanks everybody for your comments! Oops, looks like the period at the end confused things. It should work now! That thought definitely crossed my mind! With 42110’s stickers applied, it’ll have “Defender” prominently displayed on the stabilator, which might be even more suggestive. I’ll leave the missiles for modders to figure out, though.

Fantastic work!

Hi all - my second C-Model from Land Rover 42110 is complete. It's a helicopter, with full flight control & retractable landing gear. Functions: Cyclic & collective (using mixer by steph77) Co-pilot dummy cyclic & collective linked to main controls Tail rotor tilt, controlled by pedals or under passenger cabin (tail section of linkage by steph77) Rotor power with spring-loaded button, or gear on fuselage One-way clutch ensures main rotor can only turn counterclockwise Modular winch & DNR gearbox Retractable landing gear Front landing gear has suspension Sliding doors featuring a Scott-Russell linkage Stabilator with realistic (small) range of movement Video: The helicopter ended up pretty function-dense - here's the X-ray: The custom swashplate uses a method I haven't seen before - the red changeover catch allows the upper swashplate to slide up and down on the rotor axle (green), while still rotating with the green axle. The pink structure around it can tilt as necessary, to match the tilt of the lower swashplate (not pictured below). Since the swashplate surfaces aren't locked together except by gravity, you wouldn't be able to fly this helicopter upside down. My favorite function is the landing gear - while it may not be very realistic, the front landing gear linkage has a lot going on in order to allow both retraction and suspension. I also like that you don’t need to spin a linear actuator for 30 seconds - just push a button and woosh! Below is a detail of the front landing gear linkage extended (left) and retracted (right). The grey pieces are the mounting points. The other colors are to help track between left and right. There are more renders & explanations of other mechanisms in this model at https://m.imgur.com/gallery/5sYxvzE Free reverse teardown photos of this model will be posted in the next month or so. I had a great time designing this model - hope you enjoy!

This is looking awesome! You’ve really captured the spirit of the original.

Looking fantastic! I miss the old wheels but you’ve made the modern white work very well, too. Still my favorite entry so far!

Great progress! Thanks for the update, and great to see it in-action!

Great work - so far this is my favorite entry. You’ve done a great job capturing (and modernizing) the spirit of the original!

Much more difficult, but much more fun to see!

Great job! Highly functional, very attractive, and I love the modularity! It took me a while to figure out the dual differential drive because I was confused by the middle set of bevel gears, going to the engine. Love your implementation and it has a very satisfying symmetry. Is the dual differential drive inspired by the real-life excavator?

Works for me!

Not sure if there’s an easy answer to this question, but how studless is studless? If, for example, an entry has only studless beams/connectors, etc., except this part: https://www.bricklink.com/v2/catalog/catalogitem.page?P=43121 Will cases like these be a “use at your own risk” situation - up to the voters to decide? Or is any studded piece hard-stop verboten?
