Helicarrier 76042 and rotors problem

[dbpass]

Hello to all,
I'm a big fan of LEGO for so many years (considering that this year I've beaten 40 and playing LEGO since I had 4)

I was looking for a great forum where to share opinions and advice on the most beautiful sets, so here I am here ^ _ ^

I'm personally lover of all Star Wars series (they are one of the few lucky holders of the Millennium Falcon 10179 still canned) and more generally of the big and nice challenging sets to mount: B):

I do not know if this is the right place, otherwise I apologize in advance and write it in the appropriate section, but I take the opportunity to ask you a tip: I recently mounted the set of Helicarrier Marvel Super Heroes (76042) Taken from an infinite monkey, I have purchased the set power functions set out in the manual (88000 + 8883 + 8870) separately.
I turn it on and the 4 rotors do not rotate, there seems to be too little power ... among other things I have noticed already in the building phase that to make them turn there is a single crank behind that is rather tough, despite the gears being All in place and fitted perfectly as by manual ...
Question: Did anyone find the same problem? Do you have any suggestions for "oiling" everything and making the rotors more fluid in turning with the crank and, consequently, with the power function mechanism?

Thanks again to everyone,
DB

I had this exact problem and figured it out partway through the building process - basically what I did was go through a rigorous "debugging" process - I separated out the props, figured out if the axles were catching, and eventually, through lots of testing, I was able to narrow down the issue to one place that I had tightened too much. It seems to have been a common issue with this set and unfortunately it's a lot of work to isolate the issue and fix it. Good luck!

...and don't lubricate your LEGOs, most lubricants are pretty bad for the plastic.

Thx guys for suggestions ;)

 

@legozebra what do you mean with debugging process? where the problem was exactly on your side?

Thanks,

Ciao!

Basically, I kinda approached it the way I'd solve a programming issue (if you're familiar with coding). It's a tad hard to explain but I removed the propellers one by one and tried to see if the issue was in one of the four props. Since it wasn't, I removed certain parts of the technic axle system, reattaching the one I had removed before testing the next one. Finally, I removed one connection and it flowed smoothly. Once I figured out I had made it too tight in that area/it was a bit bent and hard to turn it wasn't easy to fix. Sorry I don't exactly recall where it was; I built it a few years ago. Hope this helps!
