New Arrival - RC Mobile Crane (Mould King 13107)

Yes, it was very risque... :-)

Yes, full remote control is a big advantage.

Unfortunately quality is still not so high like Lego - especially linear actuators are in poor quality. But the rest is not so bad. Also motors and remote control work well.

@ x-ray please

Ano, je to tak, motory jsou spojené se všemi pohyblivými částmi, takže je nutné ovládat přes dálkové ovládání. Jedině si pohrát s konstrukcí a zkusit udělat spojku, která by umožnila rozdělit motory a kola.

@ dakujem za rychlu odpoved. Nevadi mi to len som o tom nevedel.

Thanks for this useful information. I had sometimes problem to pair what I needed, so I used this way.

I just got the set today and testing the motors and I fount out that switching on and off is the only way to change between two motor boxes . Please tell me is that the only way or what is the function of the two grey buttons on top of control

Hi, I think it is caused by the transmission of the back of the legs. They are a bit further from the motor so there is some delay.

Vypnout první, vypnout ovladač, zapnout druhý, zapnout ovladač. Myslím, že jsem to dělal takhle.

2.4ghz and Bluetooth

I also did not found another way.

@ thanks for the reply

@@taskmaster2287 your welcome

Easiest way is to use the Mould King app. When you are using two boxes you have to push the button of your second box twice. Then you'll notice a different flash light from the second box. In the upper right corner of the app (use the "NEW 4.0" one) you can now switch between Box 1 and box 2. Enjoy!

​@@Doatmunda-yg9is Thanks for useful information.

No, I think fishing line is not flexible enough, I use a gray thread (I hope google translates it well).

Gray thread?? Material cotton or silk?? Is it special or regular but thicker??

Original black cord is not very flexible - that is the problem. So I use my own, gray thread. Also linear actuators are not very good, unfortunately I have no other to substitued. However model is very nice, with big functionality.

@ Do you think it's possible to replace the bad actuator with original lego actuator? I saw them selling separately at amazon

@@shaymeshulam8502 Yes, of course, used parts are identical with original Lego parts.

I don't understand exactly. Maybe if you can share some photo.

Not with this receiver. But new Mould King remote control (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-B8XG99q2LZM.html) has six ports.

@ I turned off and on the controller and I can control the other receiver. This is still good. I do not think the vehicle will drive while the crane is deployed in real life. So it is okay.

У него реально всё функции так быстро работают?

Hello, which cord you mean?

@ the shorter black string which responsible for the extension of the boom

@@steevankeitaro8224 I think there was no problem with the cord in my set. But I substituted the long cord (which holds the hook), original was not very elastic.

In the end I replaced the short black string with longer sewing threads to solve the problem, at the same time changed the way how the connectors connect pistons to lifting arm, now reach for new heights

@@steevankeitaro8224 I found the same solution (for the longer cord).

Hello, i got up what you need to change. First, the long axle what come from motor "D" and engage the 8 tooth gear (dark grey), the 12 tooth gear (black) and the 20 tooth gear (yellow), and transmitting the rotation to the 24 tooth gear (grey), you need to cut in 2 (or changed with shorter ones), to separate them between 2 technic beam (the dark grey and light grey beam). Then you need one additional 12 tooth gear (black), what you need to place instead of a grey distancing piece (lego ID: 3713), to engage the yellow 20 tooth gear (lego ID: 32269), what apparently dont made contact with anything, just rotating with the main axle from motor "D". So, the automated redirectioning function (what is secured with the white gear 24 tooth clutch, ID: 60c01) will be anulated, but the gear ration will be reduced. (So we will using 4 axes instead of 2, what are used initially).

That's how it worked in my case. But it is possible that a newer version can control both receivers at the same time.

@ I have 6 channel battery boxes. I bought the crane set. I'm going to check out the instructions and see if the 6 channel battery is any added value to it. If not, maybe the android phone app might allow better operation with a single control device.

@@williamdemler24 Maybe so.

Instructions should be very close to the original Lego crane - lego.brickinstructions.com/en/lego_instructions/set/42009/Mobile_Crane_MK_II.

I can take a snap with pages where are motors.

@ that would be nicee

@@ImDamian09 Hello, here are some pages - drive.google.com/drive/folders/1j2eeINkfGfCCQDXH_xwadYyPgR7uhNnx?usp=sharing

@ Thank you!!!

Hello, I changed gear ratio. I make some photos.

Hello, here are some photos - photos.app.goo.gl/bbSamgotVtzfAPGYA.

@ may I know which part of gear ratio that you changed? The pictures you posted I can't see the difference.

@@jeremycmlee Unfortunately I cannot remember, but I will take it apart so I can make another snaps.

@ Hi, appreciate if you could take out the part and shown again the gear ratio.

Do you still need help

@@True_motion1 yes if you can

I have this set from the producer (Mould King), but it is available in all bigger online shops (Aliexpress, BangGood, GearBest etc.).

@ Thanks for the answer. And I think I can't get past this model and have to buy it too

@@ducrider2149 -- got mine thro Wish best kit ive ever had

No, this is completely different set.

@ ok, i understand, is the cargo included? (the brown box shown in the video)

@@polloaztecaSRT Yes, it is part of this set - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-71Lkb28G2lU.html.

I think there is an QR code in the manual.

@ I got a MOC kit, it's made with CaDA parts, mouldking power functions, even Lego original turntables. There was no manual with it. Do you have the manual and code?

@@MrAmorti Yes, I shared it in some comment lower.

Dobrý den, to jsem nezkoušel, určitě by ale pomohlo použití XL pístů (Technic Linear Actuator Long with Dark Bluish Gray Ends - Item No: 40918c01).

@ jo to je dobrý nápad,hm tak,,dĕkuji. Mějte se

není zač - otázka je, jak lehká/těžká bude realizace :)

Zdravím, jěště bych se vás chtěl zeptat,při nabíjení vyndaváte cely batery box?mě to nejde nějak vyndat,tak jsem tam nechal zapichnutý nabíjecí kabel,abych to nemusel vyndavat.😮díky.

No, it isn't

It is Ultimate 42009 from Jurgens Technic Corner www.jurgenstechniccorner.com/index.php/moc-s/mod-s/ultimate-42009

i actually like it hehe

Tak to bohužel nemohu potvrdit - auto už je delší čas rozebrané a za tu dobu jsem hodně dílů prodal. Ale pravděpodobně fungují. Jediné motory, které jsem zničil byly ty, co jsem přetížil u modelu traktoru (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-LIhDm_YDqAQ.htmlsi=Upw6vJXjP83ZprvA) a nebo poškodil kabel ozubenými koly.
