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

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.
