Very smooth, nice job ! I thought I was going to be the only one to use these rims, but there's quite a few in the end. Fun !

Nice job! Lots of fun And the mechanical part is quite awesome too!

Hi brick fellows! I hadn't been browsing the site for quite a while and Thursday (less than a week before deadline), I spotted there was a new TC going! Moreover about motorbikes! As a motorcycle rider and lover, I absolutely had to take part. So I dug out some old school motorbike wheels I had purchased some time ago for my collection, which I hadn't actually used yet. They're not big, which calls for a small model; I figured this would fit considering the little time left. These wheels breath custom chopper style, so that's the path I went. I started with the rear wheel, I wanted it to stand out. I tried a few approaches for transmission, but chain or shaft look huge in comparison and add to the width. So I figured an exotic solution that matched all my criteria, one that would make Solex bike enthusiasts proud. I then fitted a gearbox and longitudinal flat twin, and wrapped those into a frame in the most classic bike style possible. The rear chassis with seat was a bit tricky, I had to limit the travel of the suspension and wrap the saddle and tail as close as possible around the wheel. The fork was pretty straightforward and from there, everything kinda fell into place and I could focus on details like the slickest possible headlight and gas tank, air intake and exhaust, license plate, etc. Without further ado, here's the Exocet: The model features steering, full suspension, a flat twin fake motor, a 2-speed + neutral gearbox and side stand. Details include saddle, gas tank, full exhaust line, foot rests, front and rear lights, indicators, air intake filter, speedometer, etc. It's hard to cram more than that in such a small model, but I wanted to feature a gearbox, so this is how I built it: I had to do with available parts, so no fancy color or rare parts. Anyway, I'm happy with the proportions and the looks. Cheers!

I must humbly admit is only based on imagination and available bricks. ;)

Thanks! Yes indeed, my boy is 3, so when I build for him, I gotta build strong.. :)

Another request from my dear son, which had me revamp the Emergency Vehicle. I really like the looks of this one, so it ends here too! Cheers!

"Dad, build me a dump truck!" So I did. Since I think it looks cute, I'm sharing it! Cheers!

May well be my favorite so far. This guy's a genius !

Very cool bike, and nice video! Thanks for sharing. I'd not reshape parts nor use non-Lego motors myself, but it's just my approach. There's nothing wrong using your bricks the way you like, IMO.

Thanks for the insight! I'll give LDCad a try.

Here you go: Vintage Rally Coupe.ldr Which software do you use? I was not convinced by TLG's Digital Designer, but haven't tried any other than Stud.io. Which is really good, IMO.

@TechnicRCRacer @Rudivdk Modeling is finished! Stud.io file is here: Vintage Rally Coupe.io I now have to look into creating proper instructions. But I guess the model file as it is already allows to build it; anyone here should be able to figure out Grand total: 843 parts. You'll find most of them in 42098, but a few other sources are required; the trickiest may be the L-shaped 2 x 4 liftarms in dark azure; black should be a good enough alternative. There are 2 cases of collisions in the 3D model. One is due to a bug around the driving ring connector (axles driven all the way inside as they should be cause a collision detection); the other due to a very slight constraint on the A-pillars (which is barely noticeable when actually building them). Of course shocks are extended and the panels are not snugged inside, but you get the idea, right? Enjoy! Cheers!

I've started modeling it! First thing I tackled is front axle, so I can already show you this:

Thank you so much! Yes, in fact I'm in the process of modeling it right now. It feels a lot like reverse engineering indeed, even with the actual model at hand. And it's only the first step; I'll have to think a lot about how to create building instructions that make sense; some axle with stop for example are both structural and used by the steering: they go all the way through the chassis from the outside and hold small parts inside frames... Not particularly user friendly to build..

I reinforced the transmission; it had a tendency to bend. It worked fine, but used to put the axle under constraint. Using one of those fixed the issue. Of course the teeth are unused and the transmission is kinda bulkier now, but in some sense also more realistic. All in all, I think it's an improvement. Was: Now:

3 - 1 point 5 - 1 point 7 - 1 point

My pleasure ! Glad they handled your case exactly like mine. It's a bit sad these servos are so unreliable, but it's always a nice feeling getting mails like the above

Thanks! I like small builds; with few parts and space one has to be creative! I would have loved to also add HOG steering; but I haven't figured out a good enough solution. It has, hasn't it? Thank you! Means a lot, especially from you. Finding smart solutions is what I love when building. And the satisfaction is even greater when I'm not alone to think some detail is elegant.. Cheers!

Took a couple of new pics for the show !

Thank you! Took me some time and a lot of tinkering to find a way to bring that steering around the engine. But I'm happy with that solution: simple, compact, easy Pythagorean triangle; it also gears the steering a bit down. Does the job nicely! Still, the angle of the steering column is a bit too vertical. And also a bit too much off center, but so are the seats because of the gearbox, so it's fine, I guess.

Thank you very much! I like it a lot; it's simple yet not simplistic. It's realistic, yet still a toy that I feel safe letting my 3yo play with: nothing should be too easy to break or take apart. It may be my favourite MOC so far. It rocks!

Had strictly identical symptoms. Yes, it sometimes stops a bit off center, but resets (power OFF/ON) correctly when in this position. Same when powered off on the normally functioning side: it gets back to center when the power is restored. However, on the side from which it does not recenter (release RC control) automatically, tho, it doesn't reset either. I also noticed it seems to go further on the "dead" side. This would point to something like it doesn't get the signal to stop, runs all the way to the physical limit and stops on torque/tension limitation. It then fails to run the recenter logic. Since they didn't ask me to ship back the defective one, I might try to open it, figure out how the stop signal at 90 degrees is supposed to happen and investigate. But I fear that if a team of professionals couldn't solve it in 10 years, it might prove too hard to fix. When TLG stops selling them at all, we might get third party alternatives, certainly less cheap...

Mine had a similar issues too. One mail to Lego and they sent a replacement by express mail. They didn't even ask me to ship them the defective one. I've read a lot of these servos had issues. I think TLG knows it and try to make for a bad part with good service. But it won't work for second hand, so if you need one, I suggest you buy new, directly from TLG, while they still have it available. This part dates from 2010, if I'm not mistaken. A shame they didn't issue a revised version in 10 years after so many failures...

@agrof I updated the rear end. I figured those existed in trans red, but they don't. So I went for an even more retro look with round lights and moved them down. I also added a license plate in the process; I figured I had this unused sticker... Good news is I didn't have to order parts! Was: Now: I think it better matches the rest of the car now. I also added an exhaust pipe. Not only does it look good, but it strengthens the structure too! Was: Now:
