I think you are confusing the words jeep and offroader. Jeep is a model/brand of a specific model. I do agree the 42110 feels like a supercar, it has mostly all the bells and whistles of one with excpetion of: missing a proper piston engine - I'd prefer a proper inline 4 instead of brick built I6 the gearbox could use more than 4 gears - I do of course know there were space constraints

The 42100 has no pneumatic cylinders, but Linear Actuators which are already prelubricated from the factory.

We are planning to add more options to the manager including the option on what happens to the ports when you loose connection - to coast, brake or remember last state - and for how long. This could be useful for your use case. No sorry, since iOS does not support external sources for applications.

Was about to say something like that too. An 1:8 offfroader combining the 8+R sequential gearbox and the Lo-Hi one from Defender would be a nice evolution. Also we could use with larger wheels (inside diameter of 9 studs), hubs (designed to couple with the new CV joints) and tyres to go with the 1:8 scale. Some long travel, harder shock absorbers would be nice too.

Thank you, meanwhile I already figured how it works as soon as I saw the suspension arm holding the motors. A very nice and clean solution!

I'd go with the number 3, it's simple and not too much stuff in front.

What a beauty! Can't wait to see more photos of the model (and the bunny too).

As promised we released the protocol for BuWizz 2.0: https://buwizz.com/BuWizz_2.0_API_1.3_web.pdf And of course 3.0: https://buwizz.com/BuWizz_3.0_API_3.6_web.pdf I think this might be useful for @imurvai to add in his awesome app.

I understand. Let's continue this discussion through support channel, so we don't clutter this topic.

Well done, both the car and the prints. How is the rear wheel drive done from the RC motors? Did you use pulley wheels and 3-sided connectors to make a custom CV joint?

Internally it seems almost identical to the PF L motor with an additional PCB for the position Hall sensor and ferrite magnet.

I'm really grateful for the positive feedback, just trying my best to be as helpful and transparent as possible. In case your motor does not work in servo mode on other BuWizz brick either, that could mean you have a bad motor, we already had a case like that.

Thank you for the showcase of the gearbox and explanation of why the wiggle is necessary. I sent this to our app developer in hope we can implement such a shake option in the upcoming gearbox module. Regarding the verdict, I agree that 42131 seems to be big for the fact of being big. Even with the gearbox I'm sure the model could be reduced to some 75% of the current size and half the pieces. But on the other hand we do not know what kind of requirements/expectations the CAT had, so who knows...

Just FYI I'm the person behind the technical support and I will have your BuWIzz with contacts issues replaced. As said before I can't comment on the prices, and discounts but the fact is we are having issues with procurement of semiconductor elements as is much of the electronic industry. In other news we are planning to release the control protocol for BuWIzz 2.0 and 3.0 in the following days.

Sorry, marketing and sales is not my domain, please turn to support.

Driveline could be winded up in case the last function reached its limit.

Problem might be that the driveline is still undres stress, which would make the switching much harder under such load. This procedure makes sure that any pretension in the driveline is reduced before switching. An analog is trying to pop a manual gearbox out of gear while accelerating hard. I'ts possible, but it takes much more effort than when it's not loaded.

This one actually makes more sense, especially the pullback monster trucks and the bigger H1 flagship. I also have a feeling Grohl designed the transformation vehicle, it's something totally his style.

Here's a quick update: You can download the version which can control the Lego Technic hub here: https://buwizz.com/190010208_support_for_powered_up.apk

Here's an idea I just got and simply had to test it. I discovered the old female CV connector 92906 can mate with the planetary hub's female CV joint! This allowed me to create something really unique, a portal+planetary hub hybrid: I had to use a combination of an older 14 tooth gear and a 20 tooth bevel gear in order to transfer the power: The reason for using half gears instead of normal full gears lies in the way the 92906 mates with the planetary hub, it can't slide in all the way. That's also why the lower attachment point uses a connector in such odd orientation. This combined hub has several advantages to the old portal hub (92908): A much higher end gear ratio - 7,71 compared to 3 Closer pivot point - using the rims from Defender/Ferrari the steering pivot can be a stud closer to the wheel Much stronger driveline - since there are no 8 tooth gears, U joints or axles to bend, the axle can withstand much higher forces Better gear protection - The gears are much less exposed to debris Here's a very basic axle setup with a diff lock. Such an axle has a massive 1:18 tooth gear ratio and I think with a bit more work it will be suitable for really massive and heavy (5 kg+) offroad models. Who knows, I may use it to make a proper large scale truck trial Unimog. Of course I built and tested the hub from real bricks too and I'm planning to shoot a video of the hub assembly shortly, so please stay tuned.

I think a combination of 42100 and 42129 (or 42099) is a good one, because you get a ton of motors plus suspension parts, planetary hubs and wheels.

I think we could also open a 2022 speculation topic for H2. My bet is on a PU powered (2 hubs with 8 motors or 1 hub with gearboxes) mobile crane, it's long since we had a proper large (could use the new-ish front tyres from the batmobile) 8-10 wheeled one.

I'd suggest you redesign the rear axle to the motors are flipped to face each other and use the stronger hubs to hold the wheel to reduce bending and possibility of the wheels falling off. I'd also extend the rear axle's ball joint as far as possible forward to reduce the hopping effect when accelerating. Other than that well done!

The port issues seem to be caused by the custom connectors, but they are easy to fix, even by the end-user with a simple needle to pull out the contacts out a bit. Of course they will be corrected in the next batch of connectors. Yes, firmware can be updated, we are in process of identifying bugs and correcting them for BuWizz 3.0 and eventually for 2.0 to bring functions such as wake to shake and rename to BuWizz 2.0 too. I can't talk about the price raises, since that's not my domain but I personally am working hard on identifying and fixing problems and of course pushing hard to have the protocol edited to be more user-firendly and released. But there are are lot exterior factors and partners to manage which take patience and time.
