I'm designing an RC technic car (C8 Corvette) in Stud.io that I want to race against some other people. How many L-motors will I need to get the car up to a reasonable speed? (I'd like it to go around 5-10 mph, basically anything faster than a slow crawl). I have 2 L-motors built into the car right now, but I have a feeling they won't be powerful enough. I'm planning on using a BuWizz battery pack for power and bluetooth control. The car has around 1200 parts, so it probably weighs 3 pounds or so. I built a four speed sequential transmission into the car as well. For a car of this weight, should I use 4 L-motors? -
EDIT 08/22 - CURRENT STATE : Here is a truck I just made (well, it actually took me several days) while being confined. I don't like to take apart my sets on display to MOC so I had to do with just a bunch of spare part I had, hence the strange color scheme and some questionable building technics and aesthetic choices (for example, I didn't had anything to make the front radiator grill so i had to improvise...) I wanted to make an American style Truck, inspired by the 5571, 5591, 8285 and more recently 42078, and remote controlled so I can have a little fun with it. Please don't be to harsh, this is my first Technic MOC that didn't end at the prototype status. The original goal was to test my new Buwizz but I finally used only original Lego PF element, because I rather use a physical remote than a smartphone. It is powered by a L motor (with the drivetrain as follow : Motor---16T / 16T---20T / differential / 20T--20T / differential) ) and steered with a servo, with a decent speed and a good steering lock. The IR receiver and standard AA battery box are housed in the back of the cab, and the latest can slide up for replacement by tilting the foldable spoiler forward. The spoiler can also be folded all the way down to make the cabin roof flat. The doors can be opened and the hood can be lifted, even though there is no fake engine underneath because that's where I furst intended to put the Buwizz. (Actually there is still enough room for it so I could convert the truck to a Buwizz model and remove all the biggest section of the cab for a more lightweight truck. :-) I could also run an axle under the cabin to the engine compartment and run a fake engine from the exposed 16T gear... A lot of work, thoughts, trial and errors went into the building of this truck, so I hope you will enjoy it as much as I do. There is still A LOT room for improvement, but unfortunately I was limited by the parts I had. Almost all of my grey and black liftarms and technic connectors whereused in the process ! I am not entirely satisfied by the roof of the cabin in the IR receiver area, which is a bit messy, and I really wish I had DBG curved panel for the sides instead of LBG ones. And of course, I wish I could replace the ugly black plate at the front with a proper truck grill. I also have to add a fifth wheel, as it is not able to pull anything in this configuration. It should be easy anyway, as I have a lot of mounting option at the rear (the black panel is only there for aesthetic purpose). I just have to figure out something with the parts i have left... In the end I like very much how it turned out though, and I may consider a bricklink order to fix the aforementioned issues once the lock-down is over. In the mean time, any comment and suggestion for improvement is welcome ! :-) EDIT : now with a running fake engine ! -
This and last year we got interesting Control+ electrical system that gave wider RC possibilities. They have a lot of advantages and disadvantages that were discussed here a lot in the different topics. My input here it the thing that still bothers me: The sets with motor(s), usually with a single one, purposed to move some actuators, rotate some turntables, give some air pressure (42053, 42055, for instance) Or their "manual" brothers that have the same functions powered by a manual knob(s) with possibility to add a motor to them (42029) So, why I'm talking about them? Just because these set categories have the thing that is common for them and looks useless and pointless without PF-motorization (not RC-control for drive&steer): the distribution and/or direction gearbox. You have a single motor and many levers that turns on and off some machinery functions powered by this motor. Alternatively, they have a single knob (which not very nice for play - rotate and rotate it moving some LAs, ughhh) but just made to be replaced with a motor. Other "pure-manual" sets have a lot of knobs - each for each own function, outrigger, winch, etc. One function - one knob. It is great for play with no motors, so you can raise the crane arm and release the rope at the same time just by spinning two opposite knobs (42108). My concern is, if we have Control+ as a PF replacement and still got no affordable and compact "static power source" (LiPo or a battery box) for a single Control+ motor, does it mean that we may have no "motorized" set with gearboxes in further? Updated 2020-01-30: soon we will know if 42113 Bell Osprey have a "dummy" power unit, or something else... So far we only know that the infographic presented on PoweredUp overview may be still actual. Notice the central section with a simple hub: -
The idea with this is project is to get speed from buggy motors, and torque from PU XLs, which have a very convenient shape. Powering the hungry buggy motors from 2 buwizz units and the PU XLs from the big technic hub, which will be in the rear and controlling it with the buwizz app. Servo for steering, PU L for fake v8. Perfect car. I would enter it in the mad max contest but 2 things stop me. 1, I doubt I will finish in time and 2, I don’t have any real buggy motors and will be using fake ones. -
This is an expansion, upgrade and update of the Tiger 4 x 4 x 4 The idea was to improve certain aspects of the 4x4 version: 1. The bewel gears were the weak part of the driveline, so the 6x6 uses additional 12:20 gearing after bewel gears, increasing available torque by 67% 2. Adding a second rear axle additonally helps to spread the load while climbing, increasing available overall torque by another 50%, allowing for a total of 2,5x more torque than 4x4. 3. Using defender wheels, and self-built hubs the pivot point is now a stud closer to the steering wheel and steering angle is increased from 18 to 25-30 degrees, removing the need for rear steering. 4. Center section was widened by 2 studs, allowing both gearboxes to be placed in parallel and the steering servo motor low in the center. Total gear reduction has been increased to 1:5 in high gear and 1:15 in low gear. Gear switching mechanism is now faster and more reliable. 5. Suspension is now pendular with a shock absorber in front and tandem axles with shock absorbes in the back. This allows the suspension to smoothly adjust to the terrain at slow speeds without wasting energy compressing the shock absorbers. At high speeds the shock aborbers smooth out the ride. In the picture below you can see the blue 1x7 beams which swing and allow the front suspension to act like pendular: 6. The model now has working fake engine(s) and steering wheel.I'm thinking of adding a hook arm with a winch in the back, so I can use this model to pull others out during trial truck races 7. Number of motors have been reduced by removing rear wheel steering and having one motor for the gearbox, allowing to add aditional functions as before mentioned hook arm. So...that's all about it for now, I'm only missing defender wheels to finish this monster. Yes it's going to be heavier and slower, but I expect it to be even more capable and reliable.

Silicon Valley, California, is not particularly well-known for trains, nor public transit in general. Caltrain operates a commuter service along the peninsula. While most of its modern rolling stock is too large for regular track at my typical 1:48 scale, they also own and operate a pair of MP15DC switchers: EMD offered the MP15DC as a successor to the SW1500 series of switcher, the key difference being longer standard trucks and a higher top speed. Caltrain's two units (#503 and #504) were acquired from Union Pacific, which in turn acquired them from Southern Pacific. I believe the two are usually based in San Jose, though they can be seen up and down the peninsula running various maintenance-of-way jobs or "rescuing" stalled Caltrain commuter sets. This is the first "normal" diesel locomotive I've built in a long time, and the first time I've built something local. It's relatively straightforward mechanically: two 9V "mini-motors", one driving each truck, with the battery box in between them and the receiver in the cab. Pulling power is plentiful as the locomotive is reasonably heavy for its size. Pressing down on the single exposed stud on the hood powers the battery box on/off, and the power state can be checked via the small clear window on the hood. I took advantage of many recently-introduced parts on this model, such as they grey Collectible Minifig base which I used to plate over the sides and hide the works. Grey 1 x 2 x 2 windows, truncated corner tiles, and 2 x 1 wedges are relatively recent parts that help capture the shape of this locomotive. One innovation is an improvement on the technique I used for the cab windows on the TP56 locomotive. In this model, each "half" window is held captive by rotated tiles, greatly simplifying construction (a technique that @Commander Wolf absolutely loathes). The full Brickshelf gallery is here, pending moderation. I also took a number of work-in-progress screenshots in LDD, which you might find useful. Until next time, and may your commuter train never have to be rescued by one of these! INSTRUCTIONS: https://reb.li/m/137017

Hi there as nobody else yet presented a PF mod of the 42109 car (@ozacek?), I gave it a try yesterday afternoon/evening and did a quick & dirty PF mod. The result is a replica that's not totally identical in all details but comes very close to the original from the outside with considerable changes on the chassis. Differences: * Very obvious, the colors, but that was not important for the intended task. Initially I wanted to build it in red and black, but soon switched to orange and black and later just ignored the colors to save time when searching the needed parts - I have two many models built ATM and hence am low on some essential parts in the initially desired colors. The upcoming digital model(s) will use (a) more pleasing color combination(s). * The beam connecting both sides of the cockpit was moved 1 stud forward and was constructed differently to hold the PF AA battery box in place * As I couldn't find a position for the PF Servo motor that is low enough that the hood can be closed as much as in the original 42109, I used a 1 x 9 bent liftarm to fix the hood at an elevated position, imitating the look of a huge hood scoop. This way the hood is kept shut very tightly btw. * I used curved 11 x 3 panels with 2 pin holes for the side skirts, as I find them visually more pleasing then what was used in the original 42109. * The chassis is somewhat different: Instead of 11 x 7 frames I used 7 x 5 frames as I don't have 11 x 7 frames yet; 8L axles with stop for each rear wheel - so the axles can't be pulled out, but the wheels can still get loose, though I haven't seen this yet during driving and some other minor differences. The car doesn't use a differential but drives each rear wheel with a single PF L motor. Power Functions parts used: * 2 x PF L motor * 1 x PF Servo motor * 1 x PF IR V2 receiver - optional (not needed with BuWizz) * 1 x PF IR remote control - optional (not needed with BuWizz) * 1 x PF AA battery box - optional (not needed with BuWizz) [* 1 x PF control switch - actually not really needed, if the drive lines are set up in a way that both PF L motors can run in the same direction (not needed with BuWizz)] I.e. the PF equipment that came with the 9398 - not that I have one. Enough talking/writing, here are three shots, digital model(s) will come later: Using a BuWizz instead of the PF remote control equipment saves a lot of space and weight and will make this car faster. So far I haven't used it with fresh AA batteries but only with used AA batteries and a BuWizz and even in normal mode the car seems to be quicker, not to speak of fast and ludicrous modes, where the wheels start slipping on carpet and laminate floor when going backwards at full speed in fast mode or both ways at full speed in ludicrous mode. -
Hello i would like too present you my next truck an MAN TGS 8X8 The model features 8X8 drive via 2XL motors with 4 Speed gearbox which is shiftet via 1 M motor. Steering is done via 1 Servo motor. The model was build for good offroad performance and high power, it weights around 3kg. The maximum slope it can do was 60% which is 30°. It is also able too drive in the garden in the sand. The challenge was building a strong drive train with a 4 speed gearbox in the small space. The front axles are pendular as well as the rear, i testet the front even with springs but pendular worked for me better in the terrain. The model can even be driven with pf ir receveirs and battery box. The tipping is done via 1 L motor and a self build worm gear drive because a linear actuator was too big. This model is powerd by an buwizz which works great but also was challenging because i switcht mid building too it which meant i had too redo the gearbox many times because of the new power. If you got any questions feel free to ask

Hi all, wanted to share this MOC as I "teased" it many years ago but did not finish it until now. I started building the B1 in an effort to build the smallest possible 1:48 scale PF model, but ended up building the slightly smaller A6b, and then later on the even smaller EMD Model 40. Since then the B1 has been sitting in a folder on my computer gathering virtual dust. Last year someone inquired about the model and I decided to finish it once and for all, and this is the result: This is a pretty simple model just by virtue of the small size: the build is basically the same as that of the A6, just larger due to the larger scale size of the locomotive. It actually has a lot of volume compared to something like the Model 40, but the shape of LEGO motors and electronic components means that you can basically never fully utilize the 6-wide space in an 8-wide model. The part of the model that stumped me initially was connecting the massive side frames to the body. I had tried a couple times to find a solution over the years, but I finally cheated by cartooning the tanks on the sides of the locomotive with plates such that I could fit structural components behind them. The pantograph can also move up and down! Anyway, here is my video going into more detail about the model, as well as a Brickshelf gallery (when moderated). EDIT: Instructions for this model are now for sale on Rebrickable: https://rebrickable.com/mocs/MOC-48349/NonsenseWars/148-pennsylvania-railroad-b1-power-functions-9v

Hi All, I'm new to this forum, and new to the Lego RC train world. I have just started collecting this range with my son (who's 5) so this is mostly about me.... :) In all seriousness, he is over the moon with these trains and the sets in general and we have 3 already (60051, 60197 and 60198). I'm looking for some expert guidance as to the best and most cost effective way to be able to remotely control/motorise the switch tracks (points). Having done some research online, I see there are many ways, although i haven't found a definitive step by step guide yet. It would be good to get some valuable feedback and guidance from someone who has been through this process if possible (i.e method and functionality vs cost and practicality). Appreciate the time spent reading my post and any feedback received. James.

Small rc car based off a design I came up in LDD 2 years ago (link, now with (in my eyes) slightly improved looks. Not a top-speed record breaker, a powerful tug-of-war winner vs a car, but a fun little thing to drive around. Originally everything came together off the fact that I wanted to drive the space wheels with a motor, everything else just came around. 2x m-motors w/ 1:2.084 final gear ratio and uses tank steering. To archieve small size a PF receiver with a Ni-MH 8'4V 20R8H format battery (the typical square 9v ones), which is quite underpowered (the cell might be dead too as it has been just lying around for a year or so). Probably can be BuWizz-ed with some drivetrain and body mods. I guess could also use one of those train controller blocks from PU/C+ (?) line if you've only got that system. lxf-file: download Video and a few pictures (same as from video slideshow) below. Mandatory belly shot: Cya! -

Hello everyone!! I hope I'm right in making this a new topic - and that it should be in train tech and not in licensed. I've been working for a while on my own Hogwarts Express MOC. I know I'm not the first person to do this and I bow before many people who've done superb jobs - but here's my take on it! I've linked the two YouTube videos I've made about the locomotive and the carriage so feel free to have a watch. Or if not, there are a few photos which show what I've made. I'm very happy to answer any questions, as well as pointing people in the direction of my inspirations if they're looking for some themselves.

For the last 5+ years I have been running a train under my Christmas tree, powered by a LiIon PF battery box and double motors. I recently answered a question on Bricks.stackexchange.com where someone asked for advice on which power system to buy, and the answer I had to give surprised me so much, that I went ahead and changed my own strategy immediately as well. I am now the proud owner of an oval (16+ curves, 12 straights) with a L+R set of points of 9V track, including transformer, wall wart and power-to-rail connectors. Total cost were around $120, however, this is after deducting the going BL price for other train components that came with my purchase. If I didn't exclude those, my total would have been $190. (All US dollars). This prompted me to do a quick compare on the costs of a fully working train oval for under a Christmas tree. The Oval consists of 16 curves and at least 8 straights. The cost of whatever Christmas train you choose to run is not included: Powered UP: Battery Box: $50 at LEGO S@H, $35+shipping at BrickLink (only 1 US Seller) Motor: $14 at LEGO S@H Wheels & Axles: ~$3+shipping on BrickLink for 2 axles and 4 wheels Decorative sides: ~$2.50+shipping on BrickLink Tracks: 1 Track Pack (8 straights, 4 curves): $20 at LEGO S@H, $16 on sale occasionally at other stores; 12x Curved tracks: $6+shipping at BL or: Buy set 60197 ($160 at LEGO S@H, occasionally on sale for less at other stores (e.g. currently $128 at Target) plus 4x Straight track ($7+Shipping on BL) - used ones run about the same cost as the promo prices. Depending on how you count, this is $100-$160+tax for this setup, and you need to keep a mobile phone around (or pony up another $15 for the remote control), have to keep the connection alive, and will have to replace/recharge batteries every 2-3hrs. Power Functions: Battery Box: $13 on LEGO S@H ($15+shipping on BL), or the LiIon pack which has no US-based sellers currently neither on EBay nor BL, but should go for $100-$150 if available. IR Receiver: $10+shipping for a used one on BrickLink Decorative sides: ~$2.50+shipping on BrickLink Tracks: 1 Track Pack (8 straights, 4 curves): $20 at LEGO S@H, $16 on sale occasionally at other stores; 12x Curved tracks: $6+shipping at BL or: Buy a retired Power Function set (used) such as 60051, which with patience can be bought used, complete on EBay for $125-$150. You'd need extra straight track though (see Powered Up), which runs ~$7+Shipping. Again, depending on how you count, this is a $70-$150 purchase. Likely the cheapest option currently, until prices for Power Functions start skyrocketing once all components have officially retired. You get 2-3hrs run time, and unless you add $100 to your total for a LiIon battery box, you will need to buy rechargeable batteries and a charger (or cycle through alkaline AAA's like a madman). 9V: Get a used but working copy of 4561 ($100-$150 on EBay) Buy some extra straight track: 4*$5+shipping on BL (let's call it $25) Total: $125-$175 Suddenly the convenience of never having to change batteries or recharge with a $150 9V purchase sounds pretty attractive, doesn't it? Quite fascinating, for a product that has been discontinued for almost 15 years.

Robust working 1:12 RC model of the 6x6 rocker-bogie mobility system used in Mars rovers Perseverance and Curiosity... Tons of play value. Works well over most neighborhood surfaces and terrains, but sometimes gets stuck in loose sand. What you put on top is up to you. NB: The NASA rovers are 6x6x4 platforms, with 6 wheels, all 6 driven, and the 4 corner wheels steered. At 1:12 scale, steering individual wheels with LEGO motors is out of the question. So this model is necessarily a 6x6x0 platform — but one with reasonably effective skid steering. Several years ago, made a pretty faithful working 1:12 model of Curiosity with more emphasis on visual realism than on mobility system performance. The current model vastly outperforms the old one... Purist alert: SBrick RC receiver, non-LEGO elastics used to suppress wheel spread. -

Hello all! I recently bought myself a BuWizz 2.0 and I've been experimenting with transmission designs using the new Chiron shifting bits and gears. I'm trying to figure out how to control a servo with the BuWizz unit in such a way that it only has full left, centered, and full right as options for a 3 speed transmission. The closest thing I can find is the light buttons in the control setup, but they only allow for center and full lock in one direction. Has anyone figured out a good way to control a servo like this or found a clean way around it? Thanks!

Hi all! Is there any chain that's stronger than the rather pitiful technic links? I've been wanting LEGO to make sturdy chain links using the large treads forever now, and if they do have something like that I'm unaware of it. But is there a stronger chain available from LEGO, or should I just resort to buying and cutting up some tread links? I'm picturing something pretty similar in size to the chains found in K'NEX roller coaster sets. Thanks in advance for the guidance and/or bad news! :P I'm working on a somewhat realistic boxer engine for an MOC. I thought it would be interesting to have XL motors where the camshafts would be and have the timing belt (technic chain) actually drive the thing, but of course the old links are far too weak to handle one motor, much less two. I'd like to use the large tread links since they're plenty strong enough, but the tread face is five studs wide and would 1) be obviously unrealistic, and 2) take up most of the space in the engine bay. If I have to I'll use two chains next to each other and hope that holds, but if I can I'd like to keep it as narrow as possible. Cheers!
