Hello, I'm really struggling with servo calibration. I have build a MOC (kind of racing prototype) using a PU Large motor for steering. The MOC is powered by two Buwizz 3.0 as I use the 4 PF ports to power 4 buggy motors. After having spent some time with the servo calibration failures (half turn and then nothing else) I eventually found out a working PU port. Despite the calibration being successfully completed (+90, -90 then center). I have two main issues: - it seems I'm only able to use the steering if I connect the Xbox controller. - Once I drive the MOC, the steering does not return to its zero position when I release the joystick. It only goes towards the center a little bit. Any help is greatly appreciated. Thanks.

Thanks, looks better but the side view still put me off. It looks like a car was mod into a pickup. There's something goofy, I cannot explain it better. Most probably it cannot be done better a this scale, I'm not blaming at all the designers, I think it's a great detailed model.

Hi, the one below is my motorized version of the model. 2 Buwizz 2.0 4 Chinese-replica of buggy motors 1 Servo motor (PF) I obviously started from the Buwizz instructions and adapted to the PF servo motor and to the various body works adaptations e.g. engine hood nose wing white stripe rear wing no yellow/blue parts brakes calipers 1647937125975 by _mud season_, on Flickr 1647937125959 by _mud season_, on Flickr I hope you'll like it.

Late to the party. I hope you enjoy my mod. Interiors and structural changes are from Edge of Bricks (you can find his moc on rebrickable). Exterior I took inspirations by non-Lego models and a few stuff on the back from Killasudle (the phones ;-) 1647937126007 by _mud season_, on Flickr 1647937125992 by _mud season_, on Flickr Hope the links work! bye

It's just me or the side windows are just off proportion wise? I find it too short. I like the model, but that detail is definitely wrong and I can't stand the side view.

Small update. I completed the chassis. I confirm that it can go straight even if the motors are not perfectly identical. it also drift, I hope the link works. I will now focus on the body work. Here the link to a short animated GIF of the car spinning in "Normal" speed. https://imgur.com/a/lGYE5mY In fast you have to watch not to trigger the over protection. In ludicrous... I have not had the courage to try.

Yes, I will report the results for sure. Thanks for experimenting!

the vehicle I plan to build is a road vehicle. Now the point is the definition of "smooth". If the observations done by "ord" are accurate, that 5% may provide a "smooth-enough" experience. If that 5% deviation support slides instead of jumps than it may even provide a "fun-enough" experience.

Thanks a lot, this was very informative. Furthermore I checked the forum and I failed to find, collected in a single thread, all those details. I hope this thread will also serve others. BTW: connected driving axle is not good even on a small footprint car: I tested it on a two L-motors modded Fiat 500, I did the mod for fun and the car was jumping while turning! No jumps when I further modified it using a differential.

Thanks for the reply. Nope, the mod is for a pure rwd. However left and right wheels are driven by individual RC motors that are not interconnected. Actually each wheel is driven by a pair of RC motors, but this Is a detail. The point Is that there Is no connection between left and right whatsoever. Hope this clarifies.

This may sound as a dumb question, and probably it is. It happens that I have two buwizz 2.0 currently parked and the 42125 set. I'm now thinking about modding the set following the instructions by the buwizz team and some ideas I have to turn it into a sort of 488 pista. However I see that the drive train does not make any use of differential. I wonder if the terrain friction is enough to equalize the rotation of the two independent driven wheels or if the resulting model is going to wander left/right instead of going straight. I never built an independently driven drive-train so far, I don't like the idea from a mechanical perspective, but if it works it works and I saw more than one model adopting this kind of approach.

dumb question. No differential, correct? Isn't it an issue?

Got mine Yesterday, really nice and working great. Unfortunately I discovered that one of my four Power up motors is broken and I cannot yet check the model. I have a question, did I get It right that the Speed modes are no longer effective even if I can select them in the application?

yes, I'm sorry that my comment sounded a bit lame. I know very well that buwizz 2.0 is a great product and I expect buwizz 3.0 being even better. Obviously you did your evaluations to set the tag price, price that shall not only encompass the HW part, but also the SW one. I just had a "small" letdown moment after the excitement. So to switch to a more technical question: do you confirm that 1 unit can drive: 4 PU large motors + 1 PF servo ? thanks.

I was going to preorder the beast to power my modded 42099: geared up 2 times, but with 4 motors instead of 2 + an old servo for steering >> perfect match for the buwizz 3.0 I would also have a spare connection for the lights... ,.. then I crashed on the price, 181eur on pre-sale (sorry, but I have to include vat). does any pre-sale coupon for pre-pre-sale exist that I have missed? Returning customer loyalty something? That is going to be my 5th Buwizz ...
