Ok, thank you!

Wait, I thought that was normally allowed! In the current entries, @Berthil and I have both used some custom stickers. Mine aren't particularly important to the model, but the whole model has been taken apart, so there's no opportunity for me to take new pictures without them. Do you think this is alright, given that it wasn't especially clear?

Largely because of piterx's work on self-centering, RC motorcycles, there has been a fair bit of interest in these concepts lately, with a lot of discussion going on in the threads for his models. Because of this, it seemed like a good idea to start up a dedicated thread for discussion of all sorts of RC motorcycles, rather than cluttering up preexisting threads about particular models. Hopefully this thread will enable us to discuss different bikes being built, and the techniques behind them!

Phew, thanks for the reminder! I've been putting off putting mine in the entry topic, but I guess I'd better get it up now!

Yeah, it'll be a bit annoying. I reckon if I ever need to buy any CADA stuff in the future, I'll just buy some dirt cheap clone PF extension cables and solder them in myself.

Probably approach angle would be the term for that?

It's not Technic, but the new Creator Land Rover Defender has some rather advanced suspension! Triangulated four-link live axles, I believe? I think this image is too large to embed: https://images.brickset.com/news/92683_P1077383.JPG

Wow, that's really impressive stuff! Thanks for the link!

No, I think his is just starting from the one extreme side and moving all the way to the other extreme. I don't think there's really any way to misalign a sensor on these?

Yeah, I ripped Sian wheel arches from Studio too for 3D printing, back when I was trying to piece together a multicolored Sian from my collection!

I'm pretty sure it would? I don't have anything like that on hand either, but I know I used to have Star Wars speeder bikes that used normal clips on that kind of attachment, which would imply that the diameter is the same as a standard bar. You'd have it under compression, though.

Quite cool! I like that supercar-esque approach, and the functionality looks pretty unique! Are those black wheel arch pieces 3D-printed?

Yeah, problems with those motors, in my experience, are usually based on one of two things: 1. Poor connection on that copper track. I've typically been able to fend this off by cleaning the tracks. (Some recommend using an eraser for this) and perhaps bending the tabs a little bit to add tension against the track. 2. Worn insulation where the cable enters the motor or the plug (more often the motor) This can be solved by opening up the motor, cutting out the part of the cable that was rubbing at that joint, and resoldering the shortened wire back to the motor. (This is significantly harder on Servos than other PF motors, because all four wires have to be soldered, and close together, unlike the simpler motors)

Bars will fit into both ends and go in one stud, so you might be able to get enough friction to pull it out that way.

Looks very cool! Have you tested that style of steering, where the motor is indirectly moving the forks, rather than the shift-center-of-gravity strategy? Do you think the higher center of gravity will cause problems? I'm also very impressed at how few pieces you were able to use to make a solid, lightweight frame. I'm looking forward to seeing it working, and maybe even trying to build my own version with alternate electronics!

Nice! I was reading a review of that car yesterday, and was wondering when someone would do it in Technic, especially because the wheels looked so similar to the Daytona ones. The upper part doesn't seem as high as my mental image of the real thing is, making the model here look a lot more station-wagon than SUV (though the real one is kind of in a grey area anyways), but that's probably a bit of a natural problem of trying to make a B-model of something that's actually bigger than the A-model. Good job!

Those are both very true observations! I'd agree that no gearbox and minimum gears is definitely the best option for peak performance, though sometimes a two-speed can be enjoyable for a multi purpose machine. I've built autos before, both mechanical and electrical, and I'd agree that electrical is much more practical, at least for gearboxes with 3+ gears. 2-speed planetary automatics can be somewhat practical, though, when made using a planetary hub.

That is interesting steering! I always love seeing those 14T gears being used.

Here is a presentation topic for my free book of Technic history, as requested by @Milan Backstory: As a child, I was fairly obsessive about Lego Star Wars, and spent immense amounts of time poring over my Visual Dictionaries and Character Encyclopedias. Later on, when I got into Lego Technic as a teenager, I was disappointed by the lack of any books cataloguing the Technic sets in a similar way. Due to various circumstances, in spring 2017, I found myself having a lot of spare time away from my Technic collection, so I decided to start writing a Technic book for myself as a sort of passion project. At first I was writing by hand on notebook paper, but once I had a full first draft written out, I began the process of typing, revising, and formatting the book. Finally, in late 2019, if I remember correctly, I had a completed book on my hands, so I printed myself a copy, which I've enjoyed a lot (though I think my younger self would have appreciated it more--or maybe just a self who hadn't become familiar with the subject through writing a book on it). A year later, after doing some more proofreading and adding the sets from 2020, I made it available on Eurobricks as a free download. Finally, just this week, I've released the 2021 edition, which is being presented here in a more orderly post than the old one. [EDIT: 2022 edition added!] Features: -Introduction The book begins with a short paragraph explaining some of the reasons I wrote the book (sort of like the backstory I posted above, only shorter, and written by a younger self) -Timeline A favorite feature of the aforementioned Star Wars Visual Dictionaries was undoubtedly the timeline at the start, cataloging every Star Wars set of all time in a condensed form. Because of that, I knew I would have to include one in this book. Each page covers two years, and contains small profiles for each set containing the set number, name, part count, and image. This is a good way to quickly find out what year a set is from, and can also serve as a rudimentary set index. -Book Mechanics Next, I have a section that simply explains some things about the book, such as the "Data Files" included for each set, including a sample data file for a nonexistent dream set. -Yearly Introductions Now the book gets into the meaty section. The sets are ordered by year of release, and each year begins with a page providing an overview of the year. This generally includes a quick description of notable trends, subthemes, sets, parts, or stories from a given year. The page also includes an image of the year's "Flagship" set, as well as images of the new parts released that year. For most years, I utilized the images of a year's new parts from Blakbird's Technicopedia (More about that in the section on sources), which sometimes had different logic than I would have preferred, sometimes including previously released parts that were merely introduced into the Technic theme in the given year. Nonetheless, I find it quite interesting to track the development of the Technic part palette. -Set Profiles This is what the bulk of the book is made up of. Every Technic* set ever is included in these pages, with a large section of general information such as functions, aesthetics, or other information of interest, as well as at least one image and a "Data File" These Data Files list the set's name, set number, part count, price (when available), release, and alternate model. *Which sets are truly Technic sets can be somewhat ambiguous. In the end, I included any set badged as Technic that met my criterion of being a somewhat realistic model of real-world machinery, with the idea being to exclude such sets as early Bionicle and RoboRiders. I also included three Racers cars that are built of primarily Technic parts. Updates: I plan on releasing updates for this book every year for the foreseeable future. This will likely include adding the new sets for the year onto the end, updating the timeline, and fixing any mistakes that have come to my attention. Sources: My primary sources for this book were the unofficial online Lego catalogue, Brickset.com, and the invaluable fan-made Blakbird’s Technicopedia, which exhaustively covers all Technic sets 1977 to 2001. I also consulted Bricklink.com, the official Lego catalogues I received in the mail, and Google images (mainly for images of older alternate models). I feel that the information found on Blakbird’s Technicopedia often fell outside the realm of "common knowledge," so throughout the book I have cited certain pieces of information from this website with a (BT). This website was especially valuable, and I used not only its information, but also images of sets, and the renderings of the new parts from each year. I certainly could not have created this book without these sources, which I drew heavily from for both information and images! Terms of Use: Naturally, I would have liked to monetize on this time-consuming project, but its dependence on Lego's official images prevented me from doing so, so I am offering it online here for free. Feel free to download it and read it online, or print it out to read it as a paper copy, but just don't try to make money off of it. (You'll probably hear from Lego's lawyer about infringement on their images before you hear from me about infringement on my words!) Disclaimer: Not being a real author myself, this book is necessarily imperfect in style, especially because in this mere hobby project I'm not interested in doing the seemingly infinite rewritings I hear real authors do. More worrying, though, is the possibility that I may have gotten certain details wrong about sets, especially because I own very few of these sets. I would greatly appreciate it if any readers would notify me of any errors they find! Inspiration for Printing: Here are some images of the physical copy I printed myself. I printed it at the office my parents work at for 20c CAD per page, laminated the covers and punched the holes at Staples (an office supply store), and wound in the spiral binding myself. I like this setup because it wasn't complicated to make, seems durable, and can have new years added to it (It's a pain, but it's possible). Download Link: You should be able to download the book from this link: https://drive.google.com/file/d/146GuBJdz97X-KUeAncx57QT8zZKKov02/view?usp=sharing [EDIT: 2022 Edition added here: https://drive.google.com/file/d/1y67yGqrN190WPzZ2GDrCCMyIuSGi2HH3/view?usp=sharing] I hope you enjoy it!

Yeah, my 95A worked fine, so I'd agree that you could make 85A work too with some care. Was that actually grippy, though?

I'm sure they would be, yeah!

Yeah, my experience is the same. Nice and flexy, but not sticky at all. I imagine there are specialized sticky filaments that would work better, but they'd probably require better machines than my Ender 3 and old RepRap Prusa i3. At any rate I suppose you'd want a direct drive extruder at minimum!

It could be done, but it would probably run into the same issue if it had a wide ratio spread, and because the complexity of actually getting an automatic to work right is so high, and because the complexity of the diff lock isn't insignificant, stacking the two together would add too much friction and be too unreliable to be an ideal combination. It'd be very cool if someone could pull it off, though!

Is that axle supposed to be meshing with the gears? If not, it's going to lock up those 28T gears in that spacing
