lordkarsa Posted February 4 Posted February 4 Hi Folks, I would like to present to you my Technic airplane design. It has power functions motors and pneumatics built into it. (video below) Electronic system controls: Flaps, Slats, Speed brakes/Spoilers, Trimmable horizontal stabilizer, Rudder trim, Thrust reversers, Lights and Retractable landing gear with gear doors. Pneumatic system controls: Cargo doors, Parking brake. Mechanical/Manual controls: Aileron, Elevator, Rudder, Control column, Pedals, Passenger doors, Emergency exits. Weight: 4085g Length: 138cm Wingspan: 129cm Height: 43cm Quote
Jeroen Ottens Posted February 5 Posted February 5 Amazing! Great functionality. I especially like the main landinggear and its doors, they move so well choreographed together. Quote
2GodBDGlory Posted February 5 Posted February 5 Wow, that is super fun! So much complexity and functionality! I especially liked the servo (or is it antiservo?) tab on the rudder! Quote
lordkarsa Posted February 5 Author Posted February 5 @2GodBDGloryThank you! It is an antiservo tab i think :) Quote
Carsten Svendsen Posted February 5 Posted February 5 This is exactly what I was trying to achieve about 15 years ago with my Antonov An-140. I am so happy to see that someone else managed to live out my dream, well my idea was bigger, I wanted to cover it in heatshrink wrap and actually make it fly, so I had some issues with rigidity due to trying to keep the proportions. But I totally could have build what you did if I had actually gone through with it. I'm very impressed, there are so many functions I didn't even know was necessary on an airplane too, especially the wings. Though there are some areas where I think it could need more work, honestly, it's not even worth mentioning given the scale and complexity. I know it has been hard to build, great job man! Well, maybe, the color scheme if you could call it that, isn't exactly in my taste, but on the other hand, it makes it sooooo much easier to see how it all has been built and functions. So really, that's not a minus at all. And LEGO is supposed to be fun, what's more fun than a random mish mash of colors? Quote
lordkarsa Posted February 6 Author Posted February 6 @Carsten Svendsen Thank you for your kind comments! 😊 Nice to see a comment from you! I have to admit that in the past, a long time ago, I saw your videos and I was partially inspired by them to build my own airplane. But I also have to mention https://www.youtube.com/@bobhoover1977 whose videos were also inspiring. I was also thinking about covering it but unfortunately with this size and weight something always bends and then gets disconnected so you have to fix it continuously. And additionally, I like to look at the insides of the airplane. :D Regarding flying, maybe LEGO is a bit too heavy for it, but would be fun to see it defy the laws of physics. :P I have to ask, why didn’t you finish your project? Maybe this video will inspire you to complete it? I know it’s not perfect, from time to time I upgrade/fix my projects (playlist about my airplane projects: https://tinyurl.com/46xn7y2a ), but there is always room to improve. I know the colours are not the best, but I was focused on functionality. Maybe in the future I will fix it on the next version. 😊 I’m curious about your opinion, what kind of things would you do differently, or what should be fixed? Quote

I agree that it would be fun to see it taking off, but with age comes wisdom; it's not going to happen as LEGO is just too flexible and heavy, and bulky as well. I actually like the colors, it's a nice change of pace from all monotone colored builds. For things I would've done differently, for the rudder, I would've put the actuator inside the plane instead of the outside. This is actually where I basically gave up as well, it was next to near impossible to find a good solution and I sacrificed other functions for it. However, you did manage a lot of functions, tons in fact, I am very impressed. But I definitely would have tried to keep everything contained to the fuselage, and have no sticky out bits. I don't know why I decided on pneumatics for my landing gear system, because having it all timed mechanically just seems like a way better solution. I couldn't fit the actuators in the plane, but you've used gears and worm drives. Obviously, why didn't I think of that? 7 hours ago, lordkarsa said: I have to ask, why didn’t you finish your project? Maybe this video will inspire you to complete it? I simply gave up as there were constantly battles to overcome, and it was also a pain to take apart to modify anything on the interior. If I were to redo the plane, I would certainly make sure to have detachable sections, maybe the entire top from the bottom, like a baguette cut in half. Also, I had some very strict measurements to keep, I couldn't go any more than 2 studs thick on the wings, which is why I had carbon fiber rods. This obviously limited the functions I could put in there, but at the time, I also didn't know shit about planes lol, I just build it from the pictures. And everything was black, I used black everything as I didn't really have any grey pieces at the time, it was the early 2010's after all, so trying to see how things were connected and troubleshoot was an absolute nightmare as well. I might try it again, but from looking at your model, I'm so happy that at least I inspired someone else to be creative and go the many extra miles I didn't. Bob Hoover also inspired me, like he did you, he had many great designs too. I've been off building for quite some years now, traveling is not doable with your LEGO collection, but one day I'll most certainly revisit my old projects again Quote

Yeah, as you say it's hard to put everything inside the aircraft. 21 hours ago, Carsten Svendsen said: I simply gave up as there were constantly battles to overcome, and it was also a pain to take apart to modify anything on the interior... I know, i have that issue also, that now it's very hard to excess the inside of the aircraft. Hard to fiy and hard to modify :/ 21 hours ago, Carsten Svendsen said: I might try it again... Do it! :) I would be curious how would you build it with a more experienced brain :D Do you still have the AN-140 somewhere? Quote
Carsten Svendsen Posted February 7 Posted February 7 5 hours ago, lordkarsa said: Do you still have the AN-140 somewhere? No, I have taken it completely to bits and all the parts have been sorted into their respective containers. It just took up too much space for a failed model. 5 hours ago, lordkarsa said: I would be curious how would you build it with a more experienced brain :D More experienced brain, or lots of useful references to steal ideas from ? But you're right, I do have a lot of experience, it seems to me also that your part selection was, maybe not super limited, but limited to some extent, causing you to build in a certain way. LEGO's designers aren't just one brain about building a kit after all. But yeah, it'll still be a few more years before I'm reunited with my LEGO. It's currently sitting in storage in New Zealand, and I'm in France for the foreseeable future, and then god knows where after that. Quote
Aleh Posted February 8 Posted February 8 Interesting project - truly technic!! Reminds me Sheepo's skeleton projects :) Quote
lordkarsa Posted February 9 Author Posted February 9 from which parts or sections should i make videos about? let me know guys :) Quote
sondh Posted February 9 Posted February 9 Wow that Microsoft Flight Sim X soundtrack was a nice touch! Instantly brought me back to the Windows 7 days. Quote
lordkarsa Posted February 11 Author Posted February 11 I made a video of some of the features of the airplane. I hope I was able to explain it properly. Sorry for the bad quality, unfortunately, I don't have arecording studio. Quote
2GodBDGlory Posted February 11 Posted February 11 That's cool to be able to see the mechanisms in isolation like that! Quote
Carsten Svendsen Posted February 13 Posted February 13 (edited) Cool, But I would also like to see the thrust reversers That's one of the things that really impressed me as well! Edited February 13 by Carsten Svendsen Quote

Here is the Part 2 video of the features. Enjoy! :) I also made a video of the pushbac car :) Quote
Carsten Svendsen Posted February 15 Posted February 15 Oh, that's so clever! I still am not entirely sure how it works, but I think I got it. Very cool! I'm impressed with the amount of functions you've managed to incorporate here Quote

lordkarsa Posted February 20 Author Posted February 20 Please support the model on LEGO IDEAS so this model might become a set! The link: https://ideas.lego.com/s/p:4c5055f8db9948ba85c44b81f715e989 Quote
Paul B Technic Posted March 15 Posted March 15 Very interesting idea. I love the amount of functionality this includes. Quote
lordkarsa Posted April 5 Author Posted April 5 I upgraded the engines so now they can rotate. The rotation is achieved with electric motors through chains. The reverser function is still available on the engines. Quote
