  1. Few months have gone since I built my last alternative model from set 42106 and I got desire to build another one. The first model was Pullback Racer that I built for TC18 contest - more about it is here. Then I built Pullback Plane - more about it is here. And finally now I've built Pullback Helicopter. I planned to build it even before plane but I rejected it because I didn't see the way how to connect both rotor blades with pullback motor and landing gear. Set 42106 contains only 5 bevel gears and I usually use 6 for helicopter (three pairs). Later I find solution for problem with missing gear - I saved one bevel gear by connecting axle for tail rotor blade to another pair of bevel gears that transmit motion from horizontal axle to vertical. The only con of this solution is low possition of axle for tail rotor - see picture of mechanism. The last issue, I had to solve, was possition of center of gravity - it was too close to tail so helicopter made wheelies. I prevent them by adding structure under tail rotor blade. Do you think it was all for now? No, it wasn't. I've got one more idea, much crazier idea - I wanna build Pullback Steam Engine! I focused more to functionality than its look so proportions are not correct but it really works. Pullback motor is connected to rear axle and it drives also middle axle thanks to piston-rods. Front axle with small wheels works just like stabilizer (I had to move driven axles too far to rear behind center of gravity and whole vehicle would fall on its front without small wheels). Finally I added optional flame on chimney (smoke would be better but I didn't find any in donor set). I plan to make video of steam engine in action but it will not be anytime soon. Any comments and criticism are welcomed.
  2. Here's a brief review of the set no one saw coming, including parts list and building instructions :)
  3. Hi everyone, I would like to present my latest creation to you: A lego technic helicopter inspired by the Eurocopter EC135, in particular the police version. The eurocopter is an iconic helicopter which is widely used by police, fire and ambulance services and for executive transport worldwide. In fact I see these fly over my city almost every day The model presented here is not a very identical copy of the real machine, because I always like to be a bit free with the styling. As a matter of fact this model is in the end more of a display model than something to play with. When I started this project I aimed for a relatively small and compact package with some PF comonents inside and A goodlooking bodywork. I think I found the right ballance between panels flex axles and connectors. - Dimensions: 47x13x22 Studs -Weight: 750 g -Rotor span: 47 studs -White and Dark Azure collor scheme -easy accessible PF AAA battery box -Motorized main rotor and tail rotor powered by a PF M motor -Clutch gears for safety -Tiltable rotor blades powered by a PF M motor -Controlled using a standard PF remote controller Designing the tail (rotor) was probaly the biggest nightmare of this model. All the curved shapes and angles made it very hard to put it together. On top of that, a driven axle had to be placed inside as well. The solotion regarding the tail rotor I came up with was to use a rubber band. I tried using gears as well but it turned out too bulky and very ugly. Another challenge was the Dark Azure collor scheme. Not many parts are available in this collor so that was a huge limitation as well, but in the end it looks much better then most other collors would on this model. And at last a shot together with my Audi RS1 which, despite being built in different scales, look very nice on the shelf next to each other. Also special thanks to everyone here on the forum who helped me with the design on my WIP topic. I won't make instructions for this model, but for my current WIP I will. Comments, feedback and questions are as usual highly appreciated!

    LEGO 8640 Update

    Ever since TC15, and @Lipko who (I think) came up with and @Rudivdk who used a great little variable pitch propellor system using the three-pin technic hub, I knew I had to use it for a little helicopter. I used it in a failed design, and a little executive helicopter that was not great. I wanted to try it again. After playing with some panels, I decided to try my hand at one of my favorite little sets, 8640 from 1986. It is mostly the same size, but seats two technic figs and their skis and poles. Both main and tail rotors spin, and the collective for the main rotor is controlled by the pilot. Ski and pole storage I hope you enjoy. I'll take it apart soon, and I'll make some photo instructions then.

    MOC: Minifig rescue helicopter

    Hi fellow builders My third MOC here on Eurobricks is a minifig scaled model of the brand new SAR helicopter in Norway. The Leonardo AW 101 is a magnificent machine! I start off with some important information. I built this MOC based on a model i found on Lego Ideas. The creator SimonSchepp published six pictures of his grey army version of this helicopter, and I used these with the intention of making a similar model. The result is a helicopter that looks similar, but is probably built very differently. With only six pictures available It was really difficult to figure out how to build this thing. But I think it turnes out nice, and I learned a lot along the way. Hope you like it. Minifigs deserve only the best, and the AW 101 is state of the art. You can hoist the patients in to the helicopter. The crew has lots of medical equipment available for treating patients. The helicopter flies fast and safe in all kinds of weather conditions. Fully decorated cabin, similar to the layout in the real helicopter. Size does matter, and this thing is big. Fully decorated cockpit, with collective and cyclic. I know there should to room for 2 pilots. But to maintain playability, I could only fit in one seat. The godfather of helicopters, Igor Sikorsky, deserves som credit. Any comment or questions is much appreciated. Thank you for your time. Keep building :-)
  6. The LSH-05 "Jay" Light Support Helicopter, is an aircraft developed after the Cold War and improved and updated over the years, with unique features. Born from the need for a versatile helicopter that is easy to deploy, agile and fast, with limited consumption and great autonomy, the army of Plighia has invested millions of dollars to be able to build this aircraft, succeeding. The basic version has a crew of pilot and co-pilot (the latter also has the role of gunner in the case of the assault version). It can carry 4 passengers (ME version) and a payload of 3 tons. It has a speed of 300 km / h, and an action range of 450 km. It has advanced navigation systems and avionics technologies, it also has very advanced detection, tracking and reconnaissance systems. Lego LSH-05 "Jay" Light Support Helicopter by Jordan Parmegiani, su Flickr Mission Enhanced version. This version (LSH-05ME) is capable of quickly and safely transporting a small platoon of soldiers and deploying them on any battlefield. This agile, unarmed helicopter is outfitted with outboard "benches" designed to ferry up two commandos on each side. This version is not equipped with armaments, and to defend and attack it must rely on the soldiers who are transported. Lego LSH-05 "Jay" Light Support Helicopter by Jordan Parmegiani, su Flickr Assault version. This version (LSH-05A) was developed to meet the military needs of a light attack helicopter, which could support the military on the ground, capable of moving quickly and nimbly in all battlefields. It's equipped with 2 DURR 7.62 mm 1000 rpm heavy machine guns, flanked by 2 ARGO-9 missile pods, each with 9 slots, divided into 3 air-to-air, 3 air-to-ground, and 3 anti-tank, each.

    [MOC] Rescue in Antarctica

    It’s been 92 days since I’ve landed in this godforsaken part of the world, to conduct a research that would change the future of mankind. Huh... It’s even funny now, how wrong I was to think this was such a big deal. And then, all went to hell... Staring into the vastness of the sea, the greatness of the mountains, the magnitude of these glaciers, I understand now how small we are. How nothing but specs of dust in an everchanging world we represent. Humankind... Huh... Such a vague idea, it has become. You are all so far away... And me, I’m alone, forgotten, travelling with the sea, given to the cold winds of an inhabited land. It’s like I’m part of it. Staring from the edge of the world into... nothing. I never felt so alone. Yet, strangely enough, I never felt so... alive. ... Radio static* “Central, this is Eagle 05. Please respond. Over?” “This is central coming in. Eagle 05, what is your status? Over.” “Central, I’m flying over the Volta Glacier chain, approximately 38 hours after the disaster... Uh... It’s a mess from up here. A big chunk of the rock has broken apart. I’m flying over the crack, now... Heck! It ripped right where the research facility used to be. There. You see? The crack must be about 50 kilometers... Uh... Central, please standby... What? Are you serious?... Central, there’s something on the rocks. It looks... Is that a person? Uh... We’re checking it out, please standby” “Eagle 05, please respond. Over?... Eagle 05...” “Central, this is Eagle 05. We are heading back to the station. Uh... How long ago did you say Dr. Mallorie Lynch went missing? I think... I think we found her!” ________ Louis of Nutwood. This is a re-rebuilt of the LEGO City set 7903, now performing a rescue on the sea with some minor modifications since last upload Rescue Helicopter MH-7903 . Hope you all like it. Cheers!
  8. Following my disappointment that the Osprey 42113 did not follow the normal pattern of availability and cost, I decided to build a civil aircraft MOC of a similar price point. I chose the CityAirbus because it has an interesting configuration, not seen before in LEGO Technic. The real one is all-electric, improving on the usual gas-guzzling Technic prototypes. There was also room to innovate in the model. A lot of prototype aircraft inherit a shell from an existing one and fit new equipment, which doesn't make for such an interesting model. With Technic we want to see the new mechanisms, so I left the underside open to view the gearbox. There are three motorised functions: rotor spin, a "hovering" mechanism and a movement mechanism. A single L-motor powers the 8 rotors and a selection gearbox for the other 2 functions. The right lever does the hovering mechanism, which lowers a pair of linear actuators that move clear beams to raise the aircraft off the ground. The left lever does the movement mechanism that powers a sliding axle arrangement that drives clear wheels on the feet of the scissor jack. The two manual "mechanisms" are removal of panels on each side and the ability to rolls sideways when landed, using small wheels on the skids. The red lever sows the centre of the function selection gearbox. It works like the one on the back of Claas tractor 42054. The rotor drive comes from the centre of the gearbox, using the reversing bevels, and goes up, then diagonally to reach the front rotors. The rear rotor drive goes along the top. My first prototype test model allowed the rotors to tilt in sided pairs but they do not do so in the real CityAirbus. The motor is above and to the rear of the function gearbox. The hovering mechanism is geared down by worm but has a small gear-up before the worm. A clutch protects the motor. You can see the final drive from the end of a row of 16-tooth cogs to the LA (mirrored the other side). The movement mechanism has an axle sliding in a red 8-tooth cog in between the LAs, with bevel drives to the wheels. The battery unit (any 4x8x3 one will do) is housed at the rear. The 12-tooth cog shows the control to a PF LiPo for this prototype but the PU 2-port hub could be used. The maximum hovering height is about 7cm but the movement function works as soon as the skids have left the ground. Further flight uses the traditional "swooshing" method. Walking pace would meet the real 75mph design speed at 1:20 scale! My hope is that this will help to ensure that we have LEGO Technic civil aircraft of a decent size in the range of sets, seeing as the Osprey would have been around for at least next year, had it not tripped over the "non-military" policy. As a set, the final CityAirbus model would need to be sponsored by Airbus Helicopters, who own the IP to the real CityAirbus. They would specify decals to put the livery patterns and brand names on it. The design and build time was 125 hours over about 5 weeks in August and September, quite a few hours after midnight!

  9. Once again I dug up something from the 80s... and once again it's something related to a movie police character called "Murphy" - Frank Murphy this time, to be precise. But although this Lego version of the Blue Thunder helicopter is in minifig scale unfortunately for Frank I wasn't able to incorporate functional cockpit doors... sorry Frank, you're stuck in there for all eternity! I hope you like my take on the iconic Blue Thunder from the 1983 movie. If you like it and you're up for a bit of a challenge you can find the free instructions here & some more pics here. Thanks & may the Gods have mercy upon poor old trapped Frank's soul...

    [MOC] Rescue Helicopter MH-7903

    Search & Rescue Helicopter MH-7093 This MH-65 inspired was mixed with LEGO City set 7903 is equipped with: a. Cockpit for crew of two b. Cabin with bench seating for four (easily fitting way more) c. opening eagle doors on each side. d. winch system with basket and gurney (left side) e. search light (right side) f. exposed rotors. I remember owning this set as a kid, and building this re-imagined version was nothing but a blast. Right after taking photos, I was swooshing it around my living room, feeling like a kid again. I really hope it brings a nostalgia kick as it brought me too. Let me know if you remember this set, and what you think. I'd appreciate any feedback and comments. I hope you all like it! __________ Louis of Nutwood.

  13. Hi everyone, I am FranzPlus and I am looking for supporters to my projects published on lego Ideas. I would like to propose my latest work dedicated to the multi-construction experience. I accept constructive criticism. Thanks for the attention. This Creator 6 in 1 set offers spectacular performance. Download the Helicopter and motorbike to start your adventures. The front of the Helicopter separates in a Watercraft. The Main Truck has a detailed cockpit complete with bed and TV. This 6 in 1 model is rebuilt in a Road Tractor or two Racing Cars or a Seaplane or a powerful Hot Rod and finally a Motorboat. Inspired by the multi-construction of the Lego Creator Set 3 x 1, I propose six different construction alternatives with decreasing difficulty. This set consists of 653 bricks. Get carried away by the imagination and build these realistic models. Two minifigures are included 1) Helicopter Transport Truck. (653 Bricks) 2) Road Tractor (239 Bricks) 3) Racing Cars (218 Bricks) 4) Seaplane (140 Bricks) 5) Hot Rod (124 Bricks) 6) Motorboat (76 Bricks) To design this set I used LDD and Studio. Have fun and good exploration.
  14. This model was the result of a choice I had to make. I could either come up with an entry for the Eurobricks small car contest, or I could enter the TLCB Lockdown Competition. I really didn't feel inspired to make a small car, so I went with making a C model. I chose 42098, largely because of the fact that it was the only set I hadn't started to mix into my large collection. Initially, I was going to build some kind of wheeled vehicle, but then I hit a real builder's block. At that point, I was looking at the small wheel arches, and thought that it looked kind of like the bottom parts of an attack helicopter cockpit. After I realized that, I made the cockpit section, and got going from there. This helicopter is ultimately a nonesuch, and combines design elements from a number of real and fictional helicopters, including the Hellhound helicopter from Patlabor 2, and a design I found on Deviantart called the Fujin, which was designed by MeganeRid, The rotors spin, obviously, but they also have collective pitch control, which was very hard to implement given the parts available in the set. 42098 includes a shockingly small selection of gears and other technical bits, so I had to get very creative. The rotors are at their lowest position in this picture. The collective does not use a turntable, but instead uses a brick built solution that hearkens back to the very first Technic helicopter, set 852. The actual control for this function is a lever with a red bushing, on the right of the photo. This is the blades at maximum pitch, which better shows the collar that is used to simulate a swash plate. The second most major function is the complex landing gear. A 12z gear at the end of both wings controls this function, which uses worm gears to prevent the gear from collapsing. The first pic shows the gear retracted for flight, the second and third show the gear down for landing. The last set of functions relate to the gun pod, mounted under the fuselage. The pod can be traversed 90 degrees to either side, and will clear the landing gear towers. This is controlled by a 12z gear located behind the air intakes. The gun will also elevate from horizontal to almost vertical, using a knob on the back of the pod. An underbelly view, showing the gun pod, as well as part of the rotor drivetrain. The rotor is spun by the 2 12z gears on the tail. The gun pod, up close. The rubber connectors on the forward fuselage are actually a travel lock, and can hold the gun in place when not in use. Maximum elevation. Or is this depression? I can't decide how you'd define this. On the tarmac. The landing gear do work, but I also built a stand so that this heli can be posed as if in flight, with the gear retracted. Some up close pictures: This detail is actually important. As most of you have probably noticed, this helicopter has no tail rotor, and is not coaxial, so what gives? My vision is that a real version of this helicopter would use a NOTAR system, which uses a ducted fan to effectively replace a tail rotor. That's what the large vents on the tail are supposed to be for. Now, in terms of scale, this model is quite large. CamelHog the hedgehog and Spam for scale. One last beauty shot: The color scheme may not be very military, but I'd chalk that up to this being an airshow/display team livery. All in all, I am quite happy with this model, it was a real challenge to make in the limits of the parts I had, so much so was actually running out of 3L pins, but it came together nicely, and the color scheme actually worked out a lot better than I expected it to. Now, on to the contest. Stay safe out there, folks. P.S. I'll give a shout out to the first person who is able to guess where the manufacturer's name of this heli came from.
  15. My wife asked me to take apart set 40171 I gave her few years ago. When I did it I got idea to build something from it. And what is the best alternative model from any set? Helicopter! This one is even little bit special. It features opening windscreen, both rotors can freely spin and it still keeps appearence of original hedgehog - snout, thorns and four legs. So this is what you get when you crossbreed hedgehog and helicopter - Hedgecopter Building instructions are available at buildinst.cz And this is original model: Any comments are welcomed.
  16. Few years ago I built dune buggy from set 42075 (First Responder)... ...now I am back with second alternative model - Pullback Helicopter. It features opening windscreen, engine with moving piston and cool spring loaded mechanism for spinning rotors. It works similarly to pullback motor but it uses shock absorber to store energy for spinning. I took inspiration for this mechanism from Isogawa Yoshihito's book "LEGO TECHNIC Tora no Maki". I also built this model for TLCB Lock-Down Competition. Building instructions for both models are available at buildinst.cz Any comments are welcomed.
  17. I tried to build my own alternative model from set 42061 several times in past but all my attempts failed. When I was decided to sell this set I got idea to give it last try. My initial goal was to build some kind of buggy. After few hours I built working steering and in-line fake engine driven by rear wheels. Building car out of parts from set 42061 was painful (it has pretty bad assortment of parts) and I am not totally sutisfied with look of buggy so I call it "Ugly Buggy". By the way it fits to TC18 contest but I think it is too simple to submit it there. So I use it for TLCB Lock-Down Competition instead. When I finished building buggy I decided to build more - to build something easier. So helicopter was the best choice. I took little bit of inspiration from @BusterHaus - I like how he used gear rack for tail of his helicopter. My helicopter has both rotors connected by gears so you can spin them together by turning gear on bottom of helicopter. This is also my second entry to TLCB Lock-Down Competition. Building instructions for both alternative models are available at buildinst.cz Any comments are welcomed.
  18. UH-46D Sea Knight US Navy (2) by [Maks], on Flickr Good morning. After 3,5 year hiatus I would like to present my newest creation. It's good ol' Boeing Vetrol helicopter, "the smaller Chinook", CH-46 Sea Knight. Here in UH (utility version) as used by US Navy in 60s and 70s. Here you can see the exact color scheme I tried to mimic: This model was almost entirely bulit during spring of 2017. But then DA came and I was unable to find time and motivation to buy some needed parts and finish it. But here it is, the big moment for this heli! UH-46D Sea Knight US Navy (1) by [Maks], on Flickr Flickr album Brickshelf gallery Cheers! I wish you all good health.
  19. Hi everyone, I am currently building a tower for a collabration with other members of LowLUG for Bricks am Meer. The first build, that is finished, is the remake of the Helicopter set from 2001. Feedback and questions are appreciated anytime.
  20. It's been a busy month here in thirdwiggville. This time a little Helicopter MOC based on the Sikorsky S62 helicopter with additional turbines, and a Fenestron tail. Full gallery on Flickr. Features: main rotor connected tail rotor landing gear winch sliding doors folding main rotor Much more at thirdwigg.com.
  21. This is a LEGO Transformer robot which is able to change into Mini Combat Robot and Combat Helicopter. I spent much more time than the others to make the stop motion animation in this video. I wanted to take a scene of flying helicopter and I tried it actually. But I failed to many times and I had to give up. :( Anyway, my favorite part of this video is the rolling and transforming scene. Don't miss it!
  22. Hi everyone, This is my next project. Its a replica of the brand new Agusta-Westland - AW196 Air ambulance. This model is a lightweight transport helicopter designed to be able to achieve missions in about every possible environment. This is also one LEGO project, and I have tried to take lessons from my previous helicopter MOCs. At this point I have achieved the most difficult part of the MOC. The complete control center of the rotor's head is done and perfectly functional. But before, have a look at the global model in it's WIP state: The global shape is coming out of the bricks actually :) On this picture you can see one joystick standing lateraly in behind the pilot seats: And you have the same on the other side of the aircraft. Other point of view: So, what's the goal? I already build previously helicopters with onboard command, even realistic commands. It was pleasant but not always really practical. So this time I decided to make use of a pair of joysticks, one on every lateral side. The left joystick controls the cyclic movement of the rotor. When pushing it to the front/back the swashplate incline to the front and back (forwards and backwards translation of the aircraft). Pushing the joystick up and down makes the swashplate incline left or right (lateral movement of the aircraft) The right joystick controls: the collective mouvement of the rotor when pushing it up and down The pitch of the tail rotor (command is operational, tail rotor still to build) Actually, the main rotor is perfectly functional with large amplitude movement of the blade. This amplitude was a real goal of this MOC, because I found lots of beautiful build on the net, but not really one with real large movements of the blades. Other view of the rotor head, i'll explain you all of this later ;) On the other function point of view, the BB already is placed in front of the rotor in order to assure a good wheight repartition on the 3 points landing gear. I will place now a gear box with to reversible commands on it : one for the landing gear in/out command and one other for the winch, that actually does not exist. There will also be one main clutch gearbox for the rotors, in order to be able to use of the other function without rotor rotation. So, that's it for now guys, this is the first take of it. Building time: about 20 hours actually. Any comment or idea will be appreciate.
  23. Hi everyone, It might be a bit late to start a topic for the TC15 contest, but all my Lego time went up during the last few weeks to finish another moc. I decided to start building this specific helicopter, beceause nobody has built this specific version in technic before and I quite love this one. I am aiming for a compact replica of this helicopter with some basic features using powerfunctions and without the use of specific swashplate parts: -Controlled main rotor and tail rotor by one M motor -Controlled rotor blades (collective) by one M motor using a mini linear actuator -The use of clutch gears for a safe build -All powerfunctions shall be opperated via smartphone This is where I want to start with and more manual functions can eventually be added later. Here are some pictures of the wip (sorry for the poor quality) Let me know what you think!
  24. Let me introduce you what I was working on last week - it is going to be helicopter loosely inspired by Bell 47. I call it Nighthawk because it is also my tribute to set 8412 that I got when I was child. I will feature: crank for spinning both rotors fake six-cylinder flat engine with moving pistons lever in cockpit for tilting main rotor (this is not realistic function but it is reproduction of functionality of set 8412) Since I build almost exclusively alternative models this helicopter is no exception. I only use parts from rally car 42077. And now some pictures of my progress: Initial proof of concept to ensure that I have enough gears Prototype of cab with seat and lever The first assembly of whole helicopter (before I took it apart for structural upgrades)

    [MOC] 3 Seater Helicopter

    Hi there! I bought my daughter set 60100, but the helicopter was obviously too small. Here's a revision for 3 valiant postmen:
