    Hi, I like your 42082 RC MOC with SBRICK. Is this RC MOC also for use with SBRICK and Smartphone Bluetooth control - or is it vintage infrared RC?

      hello, if you look at the inventory you can see the normal IR receiver ;-) if you leave it out and use the SBrick instead, you just need an additional extension cable ;-) greetings

    I see you use a Large motor straight into the differentials via the normal 20 tooth tan gear to drive the truck, does this not strain the motor?

      Hello, the engine runs without problems. I've driven several times for a long time. the engine is fine. hope that helps you ;-) greetings

    Just bought the instructions for the RC modification model 42043. Cant wait to start!  However I am facing some (startup) difficulties. It looks like I cannot open the 'embedded PDF pictures' from the excel file received. I like to print them out to build from old-school paper instructions. The second thing I cannot achieve is to copy the list of additional modification parts from the excel file to the '' or '' page. This so I can purchase the required parts.
    I proceeded as instructed, but BrickLink (or  page is not as seen on the instructions (different lay-out, maybe recently upgraded?).
    Therefore Bricklink is not recognizing the copy/pasted list when I paste this in the "search" section.
    Can you please advise?

      hello, please answer to your purchase confirmation. that you can not open the pdf then send you our support the pdf again.

      to Bricklink, you have to go to wanted / upload and switch to Bricklink upload XML. then just insert the XML code and you're done.

      Alternatively, you can also order the remodeling parts in our shop. you can calculate it on bricklink and then compare it with our shop. Due to the shipping costs in several shops, we are often the cheap alternative ;-)

      best regards

    Question: in step 8 of your instruction one is supposed to follow the original 42043 instruction (pages 22-27). But here, I don‘t see the 20 tooth double bevel gear in tan (plus axle and bush) being used in your instruction. Is that supposed to be left out or just a mistake? And what about the 1x7 technic beam in LBG, same question here? BTW: Is the six-cylinder engine supposed to be disconnected from the drive train? Thanks in advance

      hello, the powerfunction drive the axle. The engine has too much friction, slows down the model and strains the battery too much. If I only push the model I want to turn the motor. when i ride it rc i want to have fun. ;-) regards

    very nice addition to this model...nice!!

    hello, many have tried it but we are the only ones who made the conversion right :) with the new RC functions, the suspension is not affected. the suspension is the best of the whole model. with the servo our steering has no play. that makes driving much more fun ;-) best regards
