Wow! A big surprise for me when my 5 seconds Helicopter MOC video on YouTube got more than 5000 views in less than a day! The video shows how the rotor blades can be spinning. it only takes leas than 50 parts. The video

A racing off road buggy inspired by Ariel Nomad Tactical. ( I have tried my best to match it :-) ) https://rebrickable.com/mocs/MOC-90673/zumaidi/racing-off-road-buggy/#details

You are welcome. I am glad that the faulty motor can still give some value of knowledge.
-
Ha ha ha. Sorry I didn't get it in the 1st place. Thanks. The build is very tough and compact. Not sure which part is repairable. I guess may be the chip can be replaces but that requires special tool. In my case, it was not detectable by the hub.
-
At time -stamp 5:50, I have to cut the PCB in order to inspect the top part. from 12:10 to 12:57, I just re-arranged the parts to take photos. Is the PCB on the other side "empty" ? - you can see the back at time-stamp 5:50 the hall sensor ?
-
No. I mean people without electronic knowledge. That refers to me. I don't have any such knowledge nor qualification.
-
This part is already faulty. The hub could not detect it. Lego has replaced with a new one. Thanks. But I am curious. What has happened inside the motor. Can it be repaired by a non electronic man? So, let's open it up. There is no screw or any opening... Then I need to be a little bit tough on this. I used a knife and Philip screw driver. So, that's it. Well, if you think this 13 minute video is boring, please forgive me. Thanks for watching.

Thanks. Unfortunately I have abandoned this MOC. The width is not proportionate to the length. It will be too complicated to make the set wider.
-
Well, that is something in the pipeline. I already did a simple test -

Thanks for your feedback. Yes, there is a similarity. I guess big wheels are better looking. Btw, this one is 2 door with big wheels.
-
What do you think about this ? - all existing features of 42122 are still there - big wheels from 42124 Off Road Buggy Thanks for your feedback.

Why 2 motors side by side at front and why more vacant space at the rear ? Actually I planned to put another function which is a tag axle - the last row wheel that can be up lifted up. The function was supposed to use pneumatic. It has its own motor, pump and cylinder ( from the 42008 set) . But it did not work out as planned. All of them will make the set heavier. I need to get a more powerful pump, cylinder and a PU motor for this to happen. Thanks @Brickend and @brickless_kiwi. watch the video of the tag axle -
-
The design is actually the original 42008 front row steering. I just made minor change. Anyway, I will look into it for further improvements. Thanks
-
Yes you are right. I did not securely fix the cabin onto the chassis yet at that time. I have already rectified the issue. And also changed the last row of wheels from single axle to independent axle for each wheel. Sorry I don't know the correct terms for that. Anyway, thanks for your feedback.
-
Thank you for the observation. When I tested it, there was no issue of oversteer. Once I run the Control + app, it will check the steering calibration. It passed that point. And then it can be played as normal. Based on my knowledge so far, it the steering is not well constructed, it will fail the calibration process. I also used a custom setting on the Control + app. It also passed the calibration. A bad design will cause the motor keep running. But I appreciate if you can help me to improve the design. Thanks Btw, this is the video of the first draft of the MOC. I have rectified few issues after that.
-
Opps sorry. I am glad the I have answered your question.

here is the screenshot of the steering parts Here is the photo of the chassis

I see. I think I got it. Sorry that my 1st. post did not detail out on the RC driving. This MOC uses 2 Powered Up motors - 1 for steer and 1 for drive. And also a battery hub which is hidden inside the cabin. I use Powered Up Control + app to control the driving. The parts are listed on my Rebrickable page. On the same page, there are some photos from Studio app, my own photos of the MOC, a video and also a link to 3D model created at Sketchfab. I hope I have answered the questions to your satisfaction. Sorry again. Next time, I will provide more details on my post. Thanks for your valuable feedback and attention. Based on M_longer's post, you might be referring to the motors. It uses 2 Powered Up motors and 2 battery hub. I use the existing Control + app (c+) profile for Off Road Buggy set 42124. I hope that clarified Sorry for making you confused with the photo. More details are available at Rebrickable.com. I put the link there. Thank you again. Add text Thanks. In this MOC I use Powered Up motors and hub. Controlled by Control + app. I guess you ones can use other motors and hub but I am not sure whether the size will fit onto the chassis. Yes, adding motors for steer and drive is the 1st thing in my mind when designing it because 42008 doesn't have motors for that purpose. Thanks. It is OK. It was my mistake not to clearly explain about this on my 1st post. I assumed putting a link to my Rebrickable page was sufficient.

Yes I am still enjoy doing MOC. Can you clarify which parts that I have made you said so? Thanks.
