I think using the planetary hubs in this model would be counter-productive. Due to their 5+x gearing up they would require much more force to push the model and would just spin the gearbox and the motor too fast. Though I am suprised Lego used U joints for inboard joints rather than the new CV joints. If I see correctly the designer (Milan? Getting some 42069 vibes in this set) used a combination of a soft and hard spring in the front suspension and double hard springs in the back. That explains the bouncy-ness of the model. IMHO this is a better set than Porsche or the Chiron, the suspension actually works, it has AWD with 3 differentials, HOG, and plenty of other functions like winch and rear door lock. Only thing I don't like is the engine, a classic inline 4 would be more realistic. I'm gonna get one, maybe motorize it with the new hubs, if the original gearbox will allow it.

Glad to see the wave selectors and the yellow clutch extensions from Chiron again. The Hi-Lo gear selector is very unexpected, but welcomed function. in total the model should have 8 different gears? And I need to get me some of the new deeper rims

Wow, what an amazing C model. Not many models here with transversally mounted FWD engine!

Congratulations to all the contestants, it was a fun competition! Funny fact, this is my 5th or so EB contest in a row, where I ended up in the 4th place

I made 5 different models, each with a different suspension angle and copy pasted them into exact position to take the screenshots.

While I'm waiting for the missing parts, I started building the front axles. Here's a few photos from the build process: Each hub uses double gears, it's the only way they can survive the gear-breaking torque from an XL motor powered by BuWizz. The pendular suspension allows up to 5 studs of height difference between axles and each axle can tilt some 15-20 degrees sideways.

Here's an animation of the pendular suspension system created in LDD:

Took the time to finish the LDD model today, which I will use to demonstrate the suspnsion system: I hope the weather clears up soon, so I can start the video shooting.

You need to add a few bushes on the drive axles, or else they will slide out of the differentials. That's why you should always build with real bricks along with digital.

Wow, what and awesome model! i like the way you made the rear suspensions and drivetrain, I remmeber using the same idea years ago in a rally car. Nice job with the doors too, do they tend to bend the connectors on the roof sideways? Why was the power to the fake engine reuted in such a complicated way through so many gears?

When you say saving scale, does it mean I have to build in same scale, or can I scale up?

Can I make a larger scale model (1:8)?

Great idea to breathe new air into an old "legend". So everything goes, as long as it captures the essence of the model? BTW when will you round up the Mission to Mars contest?

I think the issue with that setup will be gear that will be geared up 3x. If it will be an 8 tooth gear, it will suffer. I dont think anything else would be an issue.

I'm sorry for the long delay, was travelling and had a busy couple of weeks... But I will start the videoshoot of thes model in the weekend, so you can expect a video soon.

I think it's time to update and rebuild the legend.. Differences between the old and the new model: Because the model will be powered by 3x BuWizz instead of 4 AA battery boxes, it will be at least a kilogam lighter. Independent suspension will be changed to a live axle suspended pendular type. This will allow for much more movement when going offroad and more even weight distribution on the axles. Gear ratio will be changed from 1:3 to 1:1,677 due to the increased power of the motors, decreased weight and improved suspension - making the model 80% faster. NO MORE U JOINTS. Since no U joint, or CV can withstand the torque of an XL motor powered by BuWizz, the motors are now directly mounted on the hubs and steer with the wheels. Because there are no U joints the axle can be narrower by 4 studs, but I had to sacrifice a stud of ground clearance comapared to the old one. Servo steering - steering is now updated with 2 servo motors, each in their own axle. Front-most axle's steering angle is 25 degrees. Rear axles no longer need steering due to... Differential steering - since all motors can be individually controlled, the BuWizz's app allows for automatic correction of motor speeds when steering. This means the model can steer even tighter by reducing the speed of the inner motors when steering. Improved wheel mounting points using parts 24122 - the torque is now sent directly to the inside of the wheels without having to use 24 tooth gears and pins. I ordered the missing components and will send photos of the build as it progresses. For the bodywork I am thinking about a red cabine, but not sure which style - high and flat, or low which stick out in front further. Additional functions will be a winch in the front and possibly a crane arm in the back - I will decide on that after I see how it performs.

Nothing a couple of the new hubs wouldn't be able to handle.

Nothing keeps you gear axle from simply tilting up and slipping. Also I see no advantage over a regular portal hub, except for a higher gear ratio, but moch lower steering angle. These planetary hubs are just really hard to use for anything outside their original purpose. I just tested and part 18587 PERFECTLY fits into the new female hub and can even drive it at a slight angle. https://www.bricklink.com/v2/catalog/catalogitem.page?P=18587&idColor=3#T=C&C=3

Thank you. Also had to use the trick with Flash player and Winrar to make it install.

Just reinstalled my windows and downloaded the latest version of LDD only to find out there are lots of bricks missing. Anyone got the 4.3.11 version?

Yes, check here: I will start working on LDD file and video soon.

I fear the day TLG will release a motorized 8x8. I think their instructions and color coding will have to be even bolder.

@Jim Can you please split the topic to one about actual CV joints and other about manufactoring finesesses?

No damage to be seen on the inside, even the pins look nice and round. It seems the male CV joint is the weak link.
