Nice part and good video! Quite expensive! Did you have to pay import fees / taxes in addition to that? And these RC parts look sick, but are a bit much for my taste too! I don‘t mind if the part looks like Lego but is made of a different material, but this does not feel right!
-
I for my part was not aware of them… Yes, a diff frame with bearings would be very cool! The one from the link is plastic though, right?
-
I had a look at their frames and I don‘t think they have ball bearings!? I was thinking about getting one and leaving out the washers… As far as I understand their description, the central holes on each side are a bit deeper, so there is less play for the components to move in the first place! Did you buy the parts from their website or from eBay? Their website refers to eBay in order to be transparent about additional cost, but their German store is empty and eBay UK lists the prices in £, so I am not sure they really include all costs!? By the way: did you see they offer metal wheel hubs now?! They are expensive but look pretty wild to me!
-
Okay, thank you!
-
Hm… Any difference besides the color?
-
I do remember a few posts from a while back about some model without published instructions, I think…
-
You are not talking about the B-model of the 42129, are you?
-
I am happy you like the idea and the alternate „power pack“ looks interesting! But the necessary delay makes me kind of sad too… Was really looking forward to building one of your MOCs again! Is it possible for you to share the parts list ahead of the instructions, so we can begin sourcing the parts? At least that way we can start building right away, once the instructions are ready!
-
Hm… why not „simply“ leave out the 3rd party parts in the instructions? And tell people where to add/exchange them if they want more performance / better integrity / improved part life on a different site? Iirc, we are only talking about the metal liftarms, the tires, foam inserts and washers, right? Or would that lead to too much frustration for those who build the model in a „pure“ fashion, because of high wear and tear?! edit: kind of a „lower performance version“? I would guess that most people interested in the model might not have the BuWizz hardware anyways and will (try to) power with different motors / power supplies?! (might be difficult without the motors, because they are integrated deeply into the structure?!) …we are talking about close to 500€ cost (before taxes?!) just for the BuWizz stuff after all…
-
After building the Greyhound, Rocky and the Hot Trot, I would love to get building instructions for this one also! …I would likely try to come up with an alternative power source, since I think BW3 is way too expensive, but this model would be a good motivation to finally getting around to doing that! Any chance you will make instructions in some form and a possible timeframe for it to happen?

I figured it out in the end, so it works as intended now! My problem was that the definition of the center position and the definition of the max steering angle are not on the same "page" in the configuration. That prevented me from making the connection at first, I guess... Manual configuration was a bit "trial & error", because I needed to set a value, then start the profile in order to test it and repeat this until everything was the way I wanted it to be. It would be very cool if this was either more interactive (changing both values while the profile is running), or if you could see the current values during configuration or at least the result of the automatic configuration! (maybe something to keep in mind in case you feel bored some day ) -

Okay, thank you for looking it up! I still have not figured out how to configure the Servo manually though… :( -

Hi, would be cool to understand how it is implemented! :) What do you mean when you say that measuring the endpoints is not precise? Using the nearest 90 degree position sounds somewhat situational. I guess this means I was lucky with the other two models, where it is working correctly?! If I remember correctly, both 42109 and 42099 use an L-Motor for steering and XL-Motor(s) for driving. (I only built 42109 once and in 421099 there was no possibility for a mixup of motors) If Lego usually ships the motors in "90-degree-alignment" and the L-Motor was never used for driving, this might explain it for my other models. Since "Hot Trot" uses 42129 as a base and has 3 L-Motors, it is certainly possible I used one of the L-Motors used for driving before as a servo now... So it is certainly possible the angle in this motor was not a multiple of 90 when I put the gear rack in place... ;) I do not have the model & remote with me right now, but I will check how to do the manual calibration later on! -

@imurvai: first of all thanks a lot for your app - really appreciate it! :) I currently have a problem with a PU motor used as a servo that maybe someone can help me with... If I use auto-calibration, the servo moves to both "endpoints" but afterwards it does not stop in the middle, but clearly off-center! At first I thought that I might have overlooked something while building the model (i.e. needing to align the motor / gear rack in a certain way upon assembly), but since the rotation encoder should have a resolution of 1 degree, I no longer think that this is the case. I also tricked the PU App to calibrate the servo (had to switch ports & connect another motor to do that) and the LEGO App calibrates correctly - pretty much dead center. Is there a know issue with auto-calibration? Maybe something to do with crossing the 0/360 rotation encoding at a bad spot? Is there a way to see the values chose by auto-calibration and modify / correct them somehow? Can the servo be calibrated manually? I did not have time to really investigate, but so far I have not been able to find a manual option. (I would also need the plain values for all extreme positions in order to do that, I guess...) Edit: I forgot to mention that I have two other models where auto-calibration works fine! (a stock 42109 & "Rocky" by @Didumos69 - I am currently building "Hot Trot", also be @Didumos69)
