I've always enjoyed the off-centre-cab shape of the classic 7760, so no sooner had I bodged my own PF-9V battery connector then I started to build one. There ended up being very little in common with the original set other than the overall body/cab shape, but anyway. The colour scheme was dictated by A: my existing parts collection, because I'm a student and don't like buying things, and B: an attempt at what this loco would look like if the British Rail Civil Engineers had used one. I quite like using this grey-yellow-black livery on locomotives, because the black around the windows and doors make them stand out against the bodywork. The handrails either side of the cab don't really make sense, but the only LBG 1x1s I had available are either horizontal clips or headlight bricks, so I put them there anyway. The cab is actually fairly open inside, but there isn't really an interior unless you count lots of wires... The front bonnet ended up held in place by gravity and friction rather than stud connections; this makes it very easy to open in order to detach the battery from the connector, which is the only way to turn the model off! With the cab removed as well, we can see there really is just a big bundle of cables in there. The receiver is only half poking out into the rear bonnet, but signal reception is still fine. In building this model I stole plenty of parts from my 20T Brake Van (and yet still didn't have enough LBG 1x1 & 1x2 bricks, hence why the cab sides are so messy). This meant it needed rebuilding, and I'm actually happier with it now - it's lost the handrails, but the yellow banding is a lot more consistent around the ends. Finally, the loco with its short works train of a bogie flat, a general purpose crane and the brake van. And, as ever, the Bricksafe folder containing the photos and LDD file can be found here: https://bricksafe.com/pages/Collet22/7760-inspired-shunter. Thank you for reading; what do you think?

CADA battery with 4 motor outputs and remote control
Ivan_M posted a topic in LEGO Technic and Model Team
I know there is a lot of buzz about Chineese clones nowadays, but this is not a clonning brand and the product is very different from BuWizz, only sharing its form factor with it. I have discussed it with @Jim and he gave me permission to make this topic. Please refrain from meaningless post that you hate anything from China and that you wouldn't buy this. Thank you I have stumbled across a very interesting piece of hardware recenty - rechargable battery with four motor outputs AND remote controller - CADA remote control. The most interesting feature is indeed dedicated controller, unlike buwizz/sbrick there is no need for smart phone. I guess video (taken by František Hajdekr) is better than words: I can only say FINALLY, the need for smart phone is what makes buwizz/sbrick unusable for me, I just want plain controller, ready in 1 second and recharchable battery. The biggest question is of course what kind of hardware is inside the BB. The only info is that the battery inside is Li-ion, no info about capacity. I'm also very interested in motor controlling chip. I don't expect it will be comparable in power with BuWizz, I expect it to be better verision of LEGO Li-pol battery. So if there is anyone here who already purchased it and is willing to open it to give us some details, I would appreciate it. -
Hello everyone, I was trying to figure the below down on my own browsing forums, searching for answers, reading a lot of articles from last 2 years however I did not find strict answers to my questions. I am sorry if some answers were already posted here and I did not find them. As I am about to spend some serious money (for me personally as I am not rich) on Lego Technic and I want to be able to create custom machines later I feel like I HAVE TO decide between Power Functions and Powered Up. 1. Is (or will) Powered Up system be customizable using Lego official App or 3rd party app? Will I be able to use Power Up motors and customize them into different than original machine so it works? 2. Should I even be coinsidering Powered Up systems for future and creating custom machines? 3. Is Power Functions a better choice for now and for future for creating custom machines? Is it easier to customize controls? 4. Are there any news or leaks that Lego will allow to customize controls of new Powered Up motors? 5. Is Power Functions better for building custom machines than Powered Up? 6. Does BuWizz or Bricks going to support and customize Powered Up? I am sorry, it all feels so overwhelming as for a beginning person that has limited budget and needs to pick carefully and plan everything ahead.

Hi all! I finished this build yesterday, and am quite happy with the resulting model, so I took it out for some pictures today. Unfortunately the batteries in the model died out before I had a chance to film it, so I'll have to do that tomorrow (feel like I need to prove that all the functions actually do work on this one ) So here it is, the Tow Truck Mk II, a combination of a European truck with a typically American "rotator crane"(??) on the back (a Eurotator?) First some information regarding this MOC (of course, you don't have to read it ) As many of you might know, I built a pneumatic tow truck/recovery truck roughly two years ago, and a lot of you even seemed to like that model! When I finished that model, I wanted to make an RC PF version with the same functions and body, and I also wanted to make one powered by just one motor, with function switching gearboxes as the ones you see in most of the official non-RC PF sets released by TLG. Well, it only took about to years to get around to actually doing it! Due to the fundamentally different techniques building with pneumatics vs mechanical functions, some compromises had to be made, and some features could even be added! Firstly, this model has no suspension. The back of the model is pretty densely packed with axles and gears and functions, so fitting live axle suspension while maintaining a somewhat acceptable overall rigidity in the model was deemed impossible (for me) very early on. Also, du to the various functions going to the front, suspension there was not worth it either. Secondly, the swing-out outriggers of the original model from 2013 needed to be unnecessarily complicated, bulky, and not very strong, so I opted for an alternative solution. However, I did manage to make the fourth axle steered, something the 2013 model did not feature As you can see, it uses the genreal colour scheme and a lot of the stickered pieces from 8109. The model was initially all yellow, like the last one, but I wanted to spice things up a little, and am very happy with the resulting colours Okay, enough babbling, here are a couple of more pictures: In the above picture, everything is deployed/opened. The motorized functions are: 1. Tiltable cabin (small LA) 2. Front stabilizers/outriggers (small LAs) 3. Front winch 4. Middle outriggers (worm drives, self locking geometry) 5. Rear stabilizers/outriggers (small LAs) 6. Wheel lift elevation (small LAs) 7. Wheel lift extending (large LA) 8. Wheel lift tilting (small LA) 9. Crane rotation (worm drive) 10. Crane lifting (large LA) 11. Crane boom extending (worm drive/z8 gear/gear racks) 12. Crane winch Other features are: -Openable doors -Working V8 engine -Openable side- and rear panels (to access battery box, as well as some chains and attachments for the towing fork) -Proportional steering with Ackermann geometry on axles 1, 2 and 3. The crane superstructure has two gearboxes for the three functions up there. That means there is a constantly running single axle going through the turntable, and the cranes functions are selected up top. This allows for infinite rotation, with none of the cranes' functions being affected. Yeah, I know that bull barmight be ever so slightly overkill, but IMO it's not too bad It can even lift things directly in front of it Lastly, the underside shot: Also, for those who haven't seen them yet, here are a couple of quick renders showing the internals of the model: And with colour coding for the various functions All pictures and renders can be found in higher resolution in the appropriate Bricksafe folder. Overall I'm quite happy with the resulting model, but even though all functions work, at least one of them is not ideal (cabin tilt; I'm looking at you). Also, I feel the crane superstructure could be made more elegant. Anyway, hope to be able to make the video tomorrow! Comments, thoughts and criticism is as always appreciated!

Hi there, I'd like to present a MOC I've been working on from time to time since a few months: It's a small RC buggy, something I'm missing from Lego: Pictures show the V2 model. An interactive 360° view of the V1 model (with different rear axle) is available here: http://pub.clusterd.net/lego/technic/mocs/buggy/ Steering: PF Servo motor Propulsion: PF L motor (geared up 28z => 20z => 12z which is good enough to drive on office carpet and short distances on thicker carpets with fresh batteries, it works great on smooth surfaces; 36z => 12z => 12z also works, but requires more power and works best on a smooth surface; RWD) I initially used it with a AAA battery box and V2 IR receiver (not shown in the V2 pictures above, where it will be fixed to the rear spoiler, the V1 model had it at a slightly different location), but the AA battery box also fits - though it looks not as good due to different mount points, and it will also be heavier then. I assume it will also work with the LiPo box and SBrick and I can - since a few weeks - confirm that it also works with a BuWizz, but then it's more something for outdoor areas, as it gets pretty quick in fast and ludicrous modes. I created the main chassis of the V1 model of this buggy during a long evening/night and added most of the body parts the following day or days, don't remember exactly. The stickers are from the 8048 set and IMO fit the buggy theme great. Steering is also from 8048. It's fun to drive around and it can also take some hits. I took inspiration (mainly for the rear shock mounting and general setup) and motivation (I wanted to have something about as small as this) mainly from this video on YT: ...and some other videos about small RC buggies. The creator's buggy itself is also roughly based on the MOC (video and instructions for V1 model) of someone else. Instead of (re)building this one, I created my own - also because I didn't have a Buggy motor at that time. I also created a V3 model. It's slightly bigger, has front lights (using PF LEDs) and uses bigger wheels but shows some deficiencies of the design: The rear axle tends to tear itself apart in this model on rough surfaces, making the gears slip. I assume this is due to the bigger wheels used in the V3 model. I use some additional axles with stop and bushes now to hold the rear axle together for a longer time. I assume this maybe could be fixed by using a frame around the two axle holes that shouldn't move apart. When doing tight turns the V3 also lifts one of the front wheels - the one on the same side as the gear that sits on the drive axle. If someone has a good explanation for this, I'd be grateful. I suspect the softer shocks compared to V2.

[ Movie ] "Excavengers" battle (PF vs Control+)
cyberdyne systems posted a topic in LEGO Technic and Model Team
Soon after I've got my 42100, I decided to use it for making something epic and funny. So, after a month of work I've made this "movie" which tells a story about the last battle between old and new. Don't take it too serious, just have fun! P.S. Moral of the story is that the winner hasn't won at all. Cos' all the fallen gained an ability to be revived into different models and live forever, but the winner will stay useless and untouched. :) -

Hi everyone. I was wondering if anyone has any experience with taking a 9v battery plug and joining it with a PF wire. Just like this MiniZip. Any suggestions, tutorials, or discussion is much appreciated. Thanks.
-
A few of you, e.g. @Toastie regretted we removed the PF connectors from our Power Brick for the control buttons. To overcome that modification, we just released a small PF power box that allows you to run your PF devices from the power grid; you no longer need a PF battery box and replace / recharge batteries. We tried to keep it as simple and small as possible. There are two PF connectors; they both provide 9V power (GND and 9V pin) and full motor power (C1 and C2 pin): one connector provides clockwise motor power, the other counterclockwise motor power. You can control the motor power by adding an IR receiver and use your PF remotes. You can connect multiple motors spinning in the same direction by stacking the PF cables. It comes with an 9V/2A power adapter. We can provide the adapter with a US, EU, UK or AU plug. You can see it in action on the video below: It's currently available in our US/International webshop, it's going to become available in our European bricklink shop in the near future. Let us know what you think!

Hello all! I know, there already exists a topic about 42110 MODs. But, considering I plan to rebuild the whole car (except exterior) - it really would be better to separate my posts in a new topic (I agree with @Nazgarot). So, for now, I just copy what I posted in 42110 - Land Rover Defender - MODs and Improvements. The actual progress is: - completed front part of the frame (it's stiff enough even without any other part of the body attached): - McPherson suspension and front differential module mounts on that frame and is easily detachable (also McPherson struts include new cv-joints from 42099): - front suspension is built with caster and KPI angles: - engine is built from 4 PF XL-motors coupled together (output gear ratio is 20:36), also it's equipped with one-way clutch (it's built years ago by @nicjasno): - given that drive shaft of the engine has half-stud offset in vertical direction, here is an "offset remover": All modules assembled look like this: And, of course, a video of the short test: This module has some little issues (at first, I need to improve stiffness of the suspension's struts - under load they bend a little bit inward, but it doesn't affect all the process of a drive), but it has a really stiff frame and it's a good start point. You can find more photos on Flickr. About the question why I decided to use XL-motors: XL-s have the biggest torque among all Lego motors (according to the @Philo's page). Buggy-motor has higher rpms, but lower torque (and it's much more expensive and bigger than XL). It's not good choice for heavy vehicles. L-motors are more compact, but, again, if you compare torque/rpm ratio among all of the motors - XLs are the best imho. I tested this setup (4 XLs) two years ago at local fest: This model hadn't any gearbox and was pretty heavy. But, as you can see, the car accelerated easily, than acceleration stopped and speed was constant - only because of low max RPMs of the XLs. Theese motors have very good potential even without gearbox. L-motors are too weak for such acceleration of heavy models. Considering I plan to add a gearbox to this rebuilt Defender - it has to be fast and powerfull))

[MOC]Truck with concrete pump - PF/pneu - 1 motor/5 functions
Ivan_M posted a topic in LEGO Technic and Model Team
Let me introduce my latest build: Truck with concrete pump Introduction I got the inspiration for this kind of truck very long ago from this spectacular build from Waler: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=558238 . It was one of the first builds I saw when my dark age ended and I kept returning to it ever since. I knew I had to build my own when the time is right. I tried it once already (not published) in smaller scale 3 years ago but I wasn't skilled enough, the scale was wrong and I lacked the parts. I hope it is better this time. I also knew that I want to build it with very different features, Waller's truck if fully RC and I have found out that I prefer single motor and gearbox and steering and drive. IMGP5397 Features & build The list of features I wanted to implement were clear from the begining - full suspension, one motor for 6 functions, 3-section pneumatic arm, gearbox with two way switches and modular build. I wanted similar build/experience like Arocs so I have borrowed few features from it, most important is the way how the 3 modules (front axles with cabin and "crane", central gearbox, rear axles) are connected together. So I took the size of the gear box and its attachment points from Arocs and made my own one within the limits. Later I had to drop the 6th output that was supposed to drive some sort of lever ("pump") inside of the hopper because of complexity. The first iteration of the gearbox was quite fine, but it struggled when the long outriggers were hood on it because I have used clutch gear before the whole gearbox. That was major flaw so I had rebuild it again (almost) from scratch and even managed to add second penumatic pump to it. Each function is proteced either by white clutch gear, rubber band or LA clutch. The gearbox is powered by one L-motor which is powerfull enough to drive everything. Concrete pump gearbox There are two switches on either side between the axles, on right there is switch for spreading outriggers and extending front ones, on left there is switch for lowering them and for pneumatic pump. Switch for arm rotation is under the turntable. The X-style outriggeres are as close to each other as possible. The problem is that the gears for the 4 mLA that spread outriggers have to turn in opposite direction on left/right side AND in opposite direction on front/rear side as well. You can probably see more from picture above. IMGP5404 IMGP5401 Rear axles are build in similar way like on arocs, the difference is that the springs are serured much better and there is build-in 1:3 reduction. Front axles are live axles with ackerman geometry and different steering angle. I'm really happy how they turned out, the spring is mounted to lower suspension arm so I was left with more space on chasis. The steering angle is very high at the cost of force required to steer. It is necessary to drive by one hand and steer by other one, the model is very heavy and steering at place is not very convenient. Rear axles are connected to V8 engine under the cabin. IMGP5414 The cabin can tilt to reveal engine. there are two seats (of course in blue), dahsboard, gear stick and two pedals inside. I have also added screen wipers and all mirrors. Arm is 3 sections. This was real science to make it as long as possible and light so the pistons can lift it. I have moved the pistons that operate 2nd and third section to opposite direction of the arm. This prooved very effective as it allowed me to make both sections at least 10 studs longer. I also wanted tubbing as nice as possible and thick tube for concrete as well. IMGP5406 IMGP5409 Full gallery: https://flic.kr/s/aHskUypnbW Video Instructions Yea, they are on the way -
We got our control buttons out! You can see them in action in the video below. We got a fair amount of feedback on our initial design of the control buttons. One to the main requests that came up was the possibility to use the buttons in combination with our nControl™ software. That was not part of the initial plan and the buttons were not designed for that. However, there are indeed applications where it makes sense to link the buttons to the software. Now that we have a web interface this would, for example, allow you to control the layout with the buttons but monitor it on a tablet. As such we decided to redesign the control buttons so the same buttons can be used: in a stand-alone way like our initial design in combination with nControl™ through a WiFi or USB link with the computer running the software (the buttons are ready for that, but the WiFi/USB brick still have to be finalized) Another major question was how many buttons could be linked into a control panel. The limiting factor is the power consumption of the buttons and that’s tricky because the power consumption depends on the type of button and how it’s used. The original power brick also had two PF1.0 connectors but as The LEGO Group is moving towards PF2.0/PU that doesn’t make much sense anymore. As such we redesigned the power brick: remove the PF1.0 connectors add a power sensor that drives a variable color LED. The color of the LED will change in function of the power consumption: green > red > red blinking. The following bricks / buttons are currently available: power brick servo motor control button for switches, boom barrier, decouplers, monorail switches. light control button for traffic lights and level crossing lights. The next step will be to create: WiFi Brick or USB brick to link the control panel with nControl™ a ‘Throttle Button’ to pilot the trains. This would control the trains through nControl™ and support our WiFi controller, LEGO PU controller and SBrick. Let us know what you think!

Welp, back onto 1/15 scale Made this little thingy in about 12 hours after Madoca's small supercar popped up in my YT recommended. BRICKSHELF (whenever uploaded) As with my Mini Nitro Menace, this year's Corvette wheelbase was taken as a base - should be compatible with the transporter truck - and so the build began. Of course, drive&steering has been done a million times already so this needed a cherry on top - the roof was what I was looking for. Making a chassis was dead easy with the slim wheels and by motorising each rear wheel independently, the need for a differential was eliminated. Thanks to the placement of the BuWizz in between the rear wheels, steering and roof motors could now populate the central tunnel and be hidden under the black 3x11 curved panels giving the interior a "cleaner" look. Now, bodywork ain't my strongest point, but I wanted it to be ferrari RED. This meant working with a very small inventory (for me) most of which you can see on the car Of course ricer butterfly doors were made to make it look cooler than it is. Have a nice weekend, Cya)

MOC: Vossloh style "DSB" locomotive with remote decoupling
Selander posted a topic in LEGO Train Tech
As regular readers of this forum well know, I have an interest in onboard remote decoupling, see for example my (old) article in Railbricks. Recently I updated the decoupling bogie design to be more mechanically robust, to have wheels with lower rolling resistance and (hopefully) to look better. With the deoupling bogie ready I needed a new locomotive to try it in....so I designed a new locomotive around the bits and pieces needed…. This time I decided to make a build solely with bricks already "in stock"....hence not the normal shopping rounds on bricklink. I found the german Vossloh locomotives and liked their light grey / green livery which also matched my available bricks and elements. The green cab really cried for white decals so I used some Danish DSB that I already had….. But DSB + Vossloh is not a combination from real-life, as far as I know, so please see this as a product of my own imagination… The locomotive is quite full of PF Components: Battery box, IR receiver, M-motor + gearing for driving the mini actuator plus a regular train motor for propulsion. -
Good Day everyone! After completing MPATEV-01 (video&LDD file coming soon) and not able to progress on Saber, decided to build something from my bucket list. And there was 8258 B. After a somewhat boring build process the final result was not very satisfying, so my first idea was to motorise it. However keeping the model as it is would be extremely boring, so the whole chassis and rear part were dismantled, leaving only the front, bonnet and hoods . Next a 4X4 (AWD probably but you've been clickbaited mwahahah ) with open diffs was made. No reduction from the XL motor but the one in-between driveshaft and diffs. On front there are two gray (old gray - undetermined type) springs and on the rear a leaf axle out of 9l links (idea by ZBLJ). Of course that horrendously enormous fake motor was kicked out and substituted with a cute mini V8. Interior is as crude as the original but now with even less foot space and a switch under the dashboard. Steering through M motor and hockey spring combo, M motor-powered winch controlled with the LBG connector on dashboard. For power I opted for a "classic" PF receiver and custom wired 9V battery neatly fixed with a net in the bed. Overall not the best performance but it's quick yet (relatively) powerful. Front winch is detacheable to improve climbing angle (approximately 50 degrees maximum). I haven't named it a MOD because most of it was made from zero, and the N2 is because this is a successor to one of my early RC MOCs - pickup N1 https://www.eurobricks.com/forum/index.php?/forums/topic/127500-moc-4x4-off-road-pickup-n1/ (my imitation of 9398 as I couldn't afford one and still can't) LDD file DOWNLOAD Video: (sorry it's 30° outside, batteries died and I ain't frying myself 2 times for some offroading outside ) Have a nice weekend, Cya later!

[MOC] Airbus Eurocopter EC135 (Police helicopter)
T Lego posted a topic in LEGO Technic and Model Team
Hi everyone, I would like to present my latest creation to you: A lego technic helicopter inspired by the Eurocopter EC135, in particular the police version. The eurocopter is an iconic helicopter which is widely used by police, fire and ambulance services and for executive transport worldwide. In fact I see these fly over my city almost every day The model presented here is not a very identical copy of the real machine, because I always like to be a bit free with the styling. As a matter of fact this model is in the end more of a display model than something to play with. When I started this project I aimed for a relatively small and compact package with some PF comonents inside and A goodlooking bodywork. I think I found the right ballance between panels flex axles and connectors. - Dimensions: 47x13x22 Studs -Weight: 750 g -Rotor span: 47 studs -White and Dark Azure collor scheme -easy accessible PF AAA battery box -Motorized main rotor and tail rotor powered by a PF M motor -Clutch gears for safety -Tiltable rotor blades powered by a PF M motor -Controlled using a standard PF remote controller Designing the tail (rotor) was probaly the biggest nightmare of this model. All the curved shapes and angles made it very hard to put it together. On top of that, a driven axle had to be placed inside as well. The solotion regarding the tail rotor I came up with was to use a rubber band. I tried using gears as well but it turned out too bulky and very ugly. Another challenge was the Dark Azure collor scheme. Not many parts are available in this collor so that was a huge limitation as well, but in the end it looks much better then most other collors would on this model. And at last a shot together with my Audi RS1 which, despite being built in different scales, look very nice on the shelf next to each other. Also special thanks to everyone here on the forum who helped me with the design on my WIP topic. I won't make instructions for this model, but for my current WIP I will. Comments, feedback and questions are as usual highly appreciated! -
I present my latest MOC, a 6x4 Dump Truck: Click pictures for highres, or visit the BrickSafe folder if you want to It is based off of the chassis I made for my 8x4 Recovery Truck last year, but obviously has lost an axle, and been adopted for remote control with Power Functions. It features: -Drive with two XL-motors -Steering with Servo-motor -Independent suspension on front axle -Live axle suspension on rear axles -Dumpable bed with one M-motor and two LAs -Openable cabin -Openable doors -V6 engine driven from both rear axles, via a lockavle central differential -PF LEDs up front -PF LED reversing lights I found a sloution to steer the rear axle, using a turntable and a linkage to the servo motor, combined with pendular suspension, but it had too much slack, and wobbled all over the place, so I ditched it. I also made a mechanism to lift and lock the rearmost axle, but that to turned out less than satisfactory, so I ditched that as well Pictures! There you can see the red lever above the XL-motor, that engages the central diff The bed is quite spacious I was unsure if the M-motor would be sufficient to tip the bed, but it turned out very well, and it has no problem, even with some load! Close up of the tipping LAs. The driving rinf you can see above the rearmost axle is from the locking mechanism I tried to make, that didn't work. I then forgot to take it out Here the cabin is tilted forward. The battery box is held in a solid structure behind the cabin, as you can see. The servo for steering is placed vertically just below the battery box. Close-up of the V6 engine, including "twin turbochargers" The side panels taken off the battery box compartment, shows the wiring and placement of the servo At the front of the bed, we have a spare wheel, and some tools ...for when you need to change a tyre (obviously) The rear axles with left wheels removed for better view. You can also see where the tipping LAs are attached And of course, the under belly shot An LDD representation of the drive line. Green is where the power from the two XLs come from, purple is the axle to the engine, cyan and orange are axles 2 and 3 respectively. All in all I am pretty pleased with the result, as I've been wanting to build this for a long time! Hope to make a video of it in the not too distant future! I will also perfect the LDD model, make it available for those who want it, and post it on rebrickable. I might even make instructions for it, if I fin the time, and can get LDraw to work again

Finally getting around to posting some of these... I've been doing a bunch of small projects this year that I don't feel warranty their own thread, so this thread is going to be a home for said small projects. PRR MP54 Some years ago I built a set of PRR P54 coaches to go with my PRR T1. At the time I thought a fun future project would be to convert the cars to MP54 spec - the EMU version of the same car. Well, the future is now! Over the past few years I've been trying to build trains using all of various the LEGO motors, and the PF train motor was still on my hit list. I don't like the PF train motor that much because it doesn't have any low-speed torque, and the wheel spacing hasn't been correct for anything I've made so far. Recently I remembered about the MP54, and I thought it would be the perfect application - fast and doesn't need a lot of torque. Here is one of the original P54s as built: And here is the MP54 conversion: Of course the main difference is that there is a battery box, receiver, and motor in the MP54, but I've also updated the original model over the years, most noticeably by slowly collecting all the frames and glass. Other minor changes include the addition of headlights and a more vanilla bogie design to match the PF motor frames. Of course you want to see it go: I was really entertained by how fast it goes! Usually I prefer gearing down such that you get more torque and less speed, but watching this zip along is a fun change of pace. The pulling power isn't actually all that bad either, but as expected, you need to be going pretty fast before the PF train motor is generating any torque. One more interesting thing is that I'm actually using BBB wheels on the PF motor instead of the usual tyred wheels. I originally tried with the official wheels, but I due to the low torque I felt like it was really bogging down in the corners, so I tried the BBBs. This is a much smoother configuration, and it doesn't feel like I'm losing all that much grip. It can definitely pull at least the other two P54s and maybe another car or two. Okay, more to come soon. Hopefully.

Hi, I would like to share my minifig-scaled remote controlled truck. It's completely made of LEGO parts and features not only driving and steering, but also working head- and rearlights (trailer only). The driving motor is a PF medium one, located at the back of the trailer but actually powering one of the truck's rear wheels. The other wheel can rotate free, therefore creating a "differential gear" effect, allowing very narrow turn circles. Steering is done by 9V micro motor, sitting at the back of the driver. Battery box and PF receiver are placed in the trailer. There is also a short video of it "in action" on my flickr page. best regards, cubo
