le60head Posted May 9, 2012 Posted May 9, 2012 Hey guys! I've finally started work on a MOC i planned to do for a long long time. I hope i manage to finish it until the end of this month. I've been seeing a lot of people sharing progress on their current work, so I decided to do the same for once :) I'm trying to recreate a particular vehicle and make it drivable. Below are some pics of where i'm currently at. I am by far not the first one to try and make a model ofthis vehicle out of LEGO, but i'm not sure it has been done with the RC Buggy Unit yet. Guess what it's supposed to be! WIP: Guess what I'm building! by le60head, on Flickr I want to thank Zblj for the instructions on his planetary gear-drive mount for big wheels. It worked like a charm, and i do not think this project would've been possible without it. P.S. The model IS missing two wheels. I't supposed to be some sort of a car, not a bike :D Hope you find it interesting! Any are comments welcome! Quote
le60head Posted May 9, 2012 Author Posted May 9, 2012 (edited) That was quick! :D www.tumblr.com LOL! please note, the front wheel is barely attached ( just for the photo actually) i'll mount it on its suspention arm as soon as i receive some parts. Edited May 9, 2012 by le60head Quote
timslegos Posted May 10, 2012 Posted May 10, 2012 Looks interesting! looking forward to more progress. tim Quote
le60head Posted May 10, 2012 Author Posted May 10, 2012 (edited) Thank you for your comments! http://www.mocpages.com/moc.php/35902 @ VMLN8R: I wasn't aware of that MOC and it's very useful to see someone else's approach. Thanks for the post! @ Kevron: Did furbie had wheels? LOL! As a matter of fact, i did have the idea of putting a stuffed animal as a driver :D I tried renaming the topic, since you guessed what i was building, but i have no rights to. If any moderator finds it necessary, could you please rename it to: WIP: Radio Controlled Batmobile Tumbler Model. Thanks! Here's where i need your ideas: Since the RC module has an auxiliary output for a third motor, i wish to try and benefit from that opportunity. What would your suggestions be for the function of a third motor? I've been thinking about raising / lowering suspension. I am guessing it would make handling worse though. Firing two of these maybe? If i recall correctly, the tumbler had some kind of missile launchers :) I'll be looking forward to your ideas! see ya! Edited May 10, 2012 by le60head Quote
Sariel Posted May 10, 2012 Posted May 10, 2012 (edited) I can tell you from experience that single beams won't be able to keep the front wheels straight when you add weight and when you start to drive fast. It takes quite a sturdy structure to handle that without the front wheels bending sideways. Edited May 10, 2012 by Sariel Quote
le60head Posted May 10, 2012 Author Posted May 10, 2012 Hi Sariel! Thanks for the advice. By "single beams", are you referring to this part in my construction: I was hoping it would be able to keep the steering wheels straight under stress. I have not tested it yet though, i'm waiting for some mini-technic turntables to arrive in order to mount the suspension arms first. The same part ( the 5m link with stoppers) is used in the8366 Racers Supersonic model it connects the wheel hubs to the center steering-block "thingy" and it works fine. Did i understand your comment correctly? if you are talking about the connection between the black angular liftarms 4/6 that hold the wheel, and the rest of the construction, they're just put together to show the placement of the front wheel - just for the picture. P.S. how's your progress at playing bass :) Quote
Sariel Posted May 10, 2012 Posted May 10, 2012 No. What you showed is a link. And this is a beam: I have not tested it yet though I wish you luck, but personally I prefer the "test first, show later" building order. It can save a lot of disappointments. Playing bass goes well, I've even spent some time with a band in a real studio :) Quote
le60head Posted May 10, 2012 Author Posted May 10, 2012 (edited) Thank you! I get your point about testing first and showing later. Patience is not one of my strong points though :) Building the right half of the vehicle is next in order. I'll test the front end ASAP after connecting the front suspension arms. It is the most challenging part of the build for me, so i hope i didn't underestimate it. I checked the rear, and the RC motor has plenty of torque with the gearing used. I don't expect any surprises there at least. Edited May 10, 2012 by le60head Quote
le60head Posted June 5, 2012 Author Posted June 5, 2012 (edited) Here I am after quite some time. steering_prototype_2 by le60head, on Flickr P.S. I'll add some description later today. Edited June 5, 2012 by le60head Quote
timslegos Posted June 5, 2012 Posted June 5, 2012 Very compact mechanism! Nice job. How is the rest of the frame turning out? tim Quote
le60head Posted June 5, 2012 Author Posted June 5, 2012 Thanks! I tried making it short. I wish to make the whole car small and light. I also didn't want to compromise on the width of the steering lock. The previous design for the steering arms failed. The problem was in the u-joints, that controlled the front wheels turning. It ended up being too wobbly, so here I am at my second attempt. If you want i can make some pics before i disassemble it. I'm about to redisign the frame according to the new steering arms. But first - the new Mythbusters episode :) Quote
