Today, I found a video from our good friend Sariel about a new, Lego compatible motor system called RCBRICKS, from a startup of the same name. These motors look quite unlike PF motors, and seem to be based off of high torque hobby servo motors, and as such are quite capable. Watch the video for more information. (It's in Polish, but the subtitles are just fine, and in English.) Here are the Pros and Cons, as far as I can see: Pro: Lots of power Highly responsive Great range Should be relatively inexpensive. Compatible with any kind of RC gear. Con: Not compatible with Lego PF system in any way. RC receivers and transmitters are expensive. Questionable battery choice. Motors are entirely new shapes, and not readily compatible with the system, meaning that they are not drop in replacements Unproven startup. Receivers and batteries are not Lego compatible. I don't know, they sound okay, but the thing is, what most people have problems with is either the power supply, or receivers of the Lego PF system, and not the motors. While I think it is a valiant attempt to rectify the Lego systems short range, I don't think they are going about it the right way. I am also kind of dubious about the idea of using a USB batter pack for this, as it is not really Lego compatible, and has to be awkwardly rubber banded in place. It would be preferable if there were a way to go from RC standard to LPF standard, as having all new motors might alienate people who just want a drop in PF receiver replacement, like SBrick. What do you guys think?

Hi, I'm wondering if anyone has tried using one of the other PF motors (8883 M-Motor, 8882 XL-Motor or 88003 L-Motor) to power a train, rather than the standard train motor? I'm curious as to which is best for use in trains, as I'd like to do a train where I don't have to rely on the standard train motor. Ideally I wouldn't use the XL Motor, as that looks a bit big to hide in a 6-wide train. I've looked for a thread like this but can't find one. I may have missed it however. Thanks!

Well, I've got a bunch of ideas and other random things, as I am building more often, so rather than make a dedicated thread for every off the cuff thing or proof of concept I turn out, I'm just going to compile it here. The first item is a proof of concept chassis for a Gottwald crane, which I meant to be an AK-912, but there are many different models that have a similar chassis, including the AMK-1000, and the AK-680. It's a WIP, but I have other projects I want to finish first, so I made this, and am currently working on an LDD file. Once that file is finished, this thing will be taken apart, so I can use the pieces for other projects, and once I am ready to give this my all, I will use the LDD file to rebuild it. Gottwald AK-912 chassis. by Saberwing007, on Flickr The model is meant to be like an official set, like 42043, meaning one motor, and no RC. The chassi has a V-12 engine, like the real thing, and 8 wheel drive, with a single middle differential. I found that given how far apart the axles are, a differential is required between the 2 sets of driven axles. The different angle between the steering axles is achieved by a diagonal beam, which is very effective. There is almost no backlash, and the axles are in sync automatically. Also, due to how it works, the axles are set to the correct angle relative to each other automatically, due to how it is built, without any calculations. Another picture of the front unit: Gottwald AK-912 chassis. by Saberwing007, on Flickr In addition, the chassis can be separated into three parts, like the real thing. Seperate by Saberwing007, on Flickr Although the steering on the front and rear units works well, it's connecting the two that has proven problematic. I blame lack of stiffness in the middle reversing linkage, and using friction pins for every steering connection. But, for now, this is finished. I will get back to it later, I don't know how much later, though.
