Great job! The suspension is the highlight for me, but the whole thing is well designed and interesting!

Go right ahead! I hope that helps

I just built myself a copy of this model, using my custom painted LBG panels. I expect that mine is likely the only LBG one out there (and also likely the ugliest, since the bodywork was compromised a bit, and the color was uninspiring) It has the four motor setup with high gearing, with drive motors powered from my hobby-ish battery, and the PF powered from my ex-camera battery. It truly is a great model!

I've done a number of cars with mechanical brakes. Here are some images of my most recent design: Bronco Sport Rear(https://bricksafe.com/pages/2GodBDGlory/ford-bronco-sport) Bronco Sport Front Unfortunately, I don't currently have any images of these hubs on their own. If you are interested in them, and can't figure it out from these images, I can try to rebuild them and get some better ones.

I guess I must not have been very clear before, but I was actually referring to physical strength (durability). What I have seen of your frame does look very robust, and it's climbing strength is also impressive! Good job!

I'd be quite interested in getting some, but they are rather expensive now...

Cool! Thanks for providing a good explanation.

Great balance of appearance, functionality, and (I think, at least) strength!

Are these new curved panels in this Space Shuttle?

Perhaps now is the time to sell mine!

As others have suggested, I would say that the key is to reduce torque (increase speed) at the input as much as possible, without slowing the drive motors down too much from the stress. Alternativly, you could try a sliding gear based design, which could be very durable, but introduces many design headaches.

Similar, but it has a much smaller gear ratio than the 1:20 the old part offers. It is a very useful part, though, and at least a partial replacement.

That's pretty sweet! I like the simplicity and high performance of it!

I suppose it is all about priorities... That planetary part's Bricklink number is x186, and is very obscure, only appearing in a single Technic parts pack in 1978. When a Bricklink seller whom I was buying pneumatics from just so happened to have this rare part for $10, I couldn't resist picking it up, but this is the first time it has come in handy. It is hard to attach to studless models, and, unfortunately, has a rather easily activated internal clutch, but it can provide huge reduction in a way that no modern piece can.

That is a pretty sweet model, especially for its time period, and I think you're right that that is the kind of thing I might build if I had a 1990s-vintage collection! (This one wasn't actually designed for the absolute maximum complexity, though, that would go to my older 1:7 Bugatti Chiron.) Thanks! I always make sure to leave at least three studs of space under my floor, because I know I'll need to fit motors and all sorts of other stuff underneath.

Thanks! I was planning on just using 1x1 square ones, but then I decided I might as well use circles for some, and then I realized that my lone quarter circle one would fit at well!

Thanks a lot!

This latest model of mine has two rather unique functions, and a number of more commonplace ones. The unique ones are a remote-controlled torque-vectoring central differential, and an automatically functioning twin-clutch rear axle. Read on for more details! Features: Opening doors, hood, and tailgate AWD with two PF L-motors and an I-4 piston engine Steering with PF M-motor, connected to steering wheel and PF switch for controlling twin-clutch rear axle Disc brakes with two PF M-motors 8-speed sequential gearbox with PF Servo motor Servo motor for twin-clutch rear axle M-motor for overriding twin-clutch rear axle M-motor for torque-vectoring central differential Front MacPherson strut suspension Rear multilink suspension More details: Aesthetics: The aesthetic was honestly rather half-hearted at the back, but the front was attractive enough for my low standards. As usual, though, the effort went into the functions. Opening stuff: Interior: The interior was fairly detailed, with tilting front seats and a 60/40 folding rear bench. Drive: A goal in this model was to model a realistic transverse drivetrain as far as it was possible, before the AWD components come into play. As such, the two PF L-motors, I-4 piston engine, and transmission were all oriented transversely. The model drove reasonably well in the lower four gears, but would not drive in the upper four. Steering: There was a PF M-motor for steering, which drove the front rack through a 1:8 worm ratio, and then a 8:24 ratio. After this, it drove some 16T gears, one of which drove the steering wheel through a chain, and another of which drove a pair of bevel gears, which flipped a PF switch through its full travel as the wheels steered. More on this switch's function later. Brakes: The disc brakes used a new design of mine in hopes of attaining greater breaking power, but this was not really to be, since the brakes were still weak. For the first time, I used two separate motors (PF M) for the front and rear, in order to avoid a challenging to package and backlash inducing mechanical linkage. Gearbox: The gearbox used a tried-and-true 8-speed sequential gearbox of my own design, which packs a lot of gears into a strong, compact structure. Here it is shifted by a PF Servo motor. Twin Clutch Rear axle This feature replicates a real feature present on Badlands versions of the Bronco Sport. It replaces the rear differential with a pair of two clutches, which allow the torque to be electronically varied between the two rear wheels. In my simplified version, a servo motor moved a rotary catch set up such that in the center, both axles' driving rings would be activated, but rotating it to either side would disconnect a wheel. This servo was driven by the aforementioned switch connected to the steering motor, so that it would automatically disconnect the inside wheel when the model steered. Rear axle lock As in the real car, I had a lock mode for the rear axle. In this mode, neither rear wheel gets disconnected when steering, causing the model to function as if it had a locked rear differential. This was done rather simply with a second switch controlling the servo motor for the wheel disconnect. When the switch was on, the axle worked as usual, but when it was off, the axle remained locked. This switch was controlled remotely with a PF M-motor Suspension: The suspension was fairly complicated, with a front MacPherson strut setup, and a rear multilink setup. The rear suspension was directly copied from a third-gen Ford Escape's rear axle, so it ended up having four links (as well as a link for brakes), which were a longitudinal link, a lower wishbone, and two transverse links. The front suspension used one hard 6.5L shock per side, and the rear used a hard 6.5L shock per side, as well as some rubber band assistance (I know it's a cheap solution). Overall, the model provided me with interesting mechanical challenges, which is my main motivation for building. As always with my large, complex models, it was hardly an enjoyable car to drive around (I think I drove it twice: Once for testing, and once on video), didn't work flawlessly (The steering could be hesitant to steer, and the upper four gears didn't work), and didn't look perfect, but it succeeded at my goals of packing a lot of realistic, interesting functions into a reasonably small package.

Interesting work!

Nice work! This is one of the more compact, workable designs I have seen, so I'll have to try it out soon.

Now if they could get the axlehole off by, say, 45 degrees instead of a mere one or two, it could be a useful part!

That's a neat part! I've been lubricating parts for my high-powered models, but that would be a better solution!

That's pretty cool! Thanks for sharing it!

It sure seems that it would be possible if one were willing to give up the stacking!

It is quite an interesting idea! I would say, though, that in a truly fast, buggy motor-powered vehicle, one might prefer an "engine brake" to the coasting ability, but the mechanism is still innovative and worth seeing!
