  1. This MOC is an alternative model for the set 42140 "Transformation vehicle", as the name implies, it's a generic racing ripsaw. The set's original model is already a kind of ripsaw, but i had to create a traditional one and due to the set's high contrasting colors, i couldn't do a military version, so i went the other direction and built a design for racing. Having said that, i also couln't gear it down for torque as it would become very strong, but slow to be considered a racer, but I also didn't want to gear it up for speed adding unnecessary gear friction and making it stall at the smallest obstacle, so I went with a gearless 1:1 ratio, allowing the MOC to reach a reasonable speed but also have decent off-roading capabilities. Physical characteristics: Length: 33.7cm / 42.1 studs Width: 20.8cm / 26 studs Height: 16.4cm / 20.5 studs Weight: 713g (without batteries) Functions: - Remote-controlled drive and steering. - Independent front suspension. Worth mentioning aspects: - Gearless 1:1 ratio for the least amount of friction possible. - Drive is on the rear using the larger sprocket wheels for higher speed. - Good ground clearance for its size (4 studs), for solid off-road performance. - The batteries can be easily swapped from below, no obstructions. - The driver's cabin can be opened to easily access the hub's button. Here are some real photos: VIDEO: As usual, the parts list and building instructions can be found on my rebrickable.
  2. There is a picture on the MOC post that shows the mechanism, basically, the only thing that connects the transmission to the fake engine is a single 5l liftarm which has the transmission axle in the middle pin hole with a gear, and has another gear at the top pin hole, as the transmission rotates, this liftarm will go either to the left or right, engaging on different gears, the pin i show in the video connects to the bottom pin hole of the 5l liftarm locking it in a 100% vertical position, keeping it from touching the gears on either side, so no connection to the transmission is active this way.
  3. Yeah, i didn't have a clear 100% idea about how I wanted the doors to be like, that's why I think they ended up being a bit rough, yeah, I did knwo I wanted a locking mechanism, so the panels i used seemed logical because of the pin holes available and being flat. Thanks, for me it was logical to include a way to disconnect the fake engine and reduce friction for maximum RC performance since this MOC is quite heavy.
  4. Thanks, just trying to make everything clear for everyone.
  5. I wanted to make an original Hot Rod MOC for quite some time, but something different from what we usually see, which is either a T-bucket version, or a "crazy" racing version. My direction was towards a conservative, modern design, while still keeping some lines classic of Hot Rods. I completely designed it within bricklink's studio software first, without being limited by pieces i didn't have, then, only after finishing the design, did I buy all the necessary parts to actually build it. QUICK DETAILS: It is in the 1:10 scale, measures almost 49cm of length, 24cm of width and almost 17cm of heigth; weigths more than 2200 grams; it requires 2407 pieces, a lot of them are rare. It is remote controlled: by default, only the drive and steering are RC, but the fake engine and lights (optional) can become RC as well. Blue pins usage was reduced to a minimum (some are visible on a few pictures and renderizations due to a lapse of mine, but are not present on the final, public version). Since the color scheme is black and white, I prioritized black or white piece versions, because of this, it needs quite a few rare parts. FUNCTIONS: - Remote-controlled RWD using 2 PF xl-motors. - Remote-controlled steering using 1 PF servo motor. - Independent suspension on all 4 wheels. - Functional fake engine which can be activated either manually or with a PF m-motor. - Hood can be opened and has a manual, simple locking mechanism. - Wingull doors can be opened and have a semi-automatic locking mechanism. - Trunk door can be opened and has a manual, simple locking mechanism. OTHER RELATED ASPECTS: - It's ready to add electric lights on the headlights. - The fake engine function can be disabled via a lid below the car to reduce friction on the transmission and squeeze a bit more RC performance. FRONT SUSPENSION: It's as simple as it gets, i used the wishbone arms usually found in F1 sets because they provided the visuals i was looking for. REAR SUSPENSION: Another simple design with focus on stability since they are the ones pushing the MOC around, not really much else to say here. STEERING: Nothing special here, the simplest designs work the best. The MOC has a very good turning ratio taking into account its scale. TRANSMISSION (REAR WHEELS): The transmission was kept as simple as possible to reduce friction; the 2 xl-motors have a slow rotation, so i geared them up 1:3 which means the Hot Rod can achieve a nice speed on flat surfaces, but has difficulty off-roading and it's not able to tackle slopes. While building, anyone can easily change this for lower speed and higher torque with a different gear combination, but being an Hot Rod, i aimed for speed. TRANSMISSION (FAKE ENGINE): This is probably the most interesting part in terms of mechanisms. The fake engine has a dedicated m-motor to keep it running at a fixed rotation speed, which can increase when the xl-motors drive the MOC around. It has a mechanism that switches side and gears when the Hot Rod is going forward or backwards, so that the fake engine always accelerates and rotates in the same direction regardless of the Hot Rod going forward or backwards. The fake engine also rotates with all electric motors turned off, just by manually pushing the MOC around. The cooling fan rotates via a rubber band which I couldn't represent on this renderization. MISCELANEOUS: The fake engine has some details to it, like an air intake, supercharger, and exhaust pipes; it has a simple interior with a non-functional steering wheel, driver and passenger seats, tablier, dashboard and two small levers; the two battery packs with their on/off button are located right behind the seats for easier access with just one finger; the trunk has a considerable amount of space, but it's all occupied by the battery packs, IR receivers and excess cables from the electric components, so unless you manage all that very well, it won't be able to store anything else. Building instructions are free for everyone and are available on my rebrickable. REAL PHOTOS: VIDEO:
  6. This is an alternative model for the set 42109, as the name implies, it's an hypercar. The owners of the set and the internet in general, usually complain about two things, the ugly looks of the original rally car, and being slow. This MOC tries to address those two issues, i tried to make it look interesting (given the available pieces on the set), and be fast (i mean, this little guy is amazingly fast for its size). Physical characteristics: Length: 30.4cm / 38 studs Width: 13.6cm / 17 studs Heigth: 9.6cm / 12 studs Weight: 727g (with batteries) Functions: - Remote-controlled steering - Remote-controlled drive on the rear wheels: RWD Miscelanious aspects: - The final gear ratio from the xl-motor into the rear wheels is 1:3 - Batteries can be easily swapped from below. - The roof can be opened to reach the hub button. Here are some real pictures of the MOC: Feel free to share your thoughts. As usual, for anyone who fancys building this MOC, the instructions are available on my rebrickable.
  7. Oh, i suppose it can be done, but then, moving pieces around could substantially change the MOC appearance.
  8. Being a pickup, it just didn't look right being able to see the motors and structure below the dump bed, so, yeah. I believe so, the MOC is like this because it's an alternative model of an exixting set and i was limited by the parts on the set. The wheels can perfectly be changed to smaller/narrower ones, and the body structure changed for higher ground clearance, but it won't be a proper B-Model anymore.
  9. Well, i'm a small creator, but I want to make my creations public here, and like other creators I find it uneffective to create a new topic for every MOC, so, from now on, I will use only this topic to publish new creations. Here comes a new MOC: This is an alternative model for the set 42099 "4x4 X-Treme Off-roader". It's an off-road pickup, i call it "Turbo Pickup". I wanted to create a vehicle that didn't use the geared down wheel hubs available on the set, so that i could achieve higher speeds with less gears involved and consequently less friction, while at the same time designing something different from what is already available and this is what i came up with: an off-road racing pickup. It is RWD and the two rear wheels don't use the hubs, they're connected to a differential which has both XL-motors driving it one on each side. This uncommon setup surprised me with its strength and speed, the motors won't stall easily on this one, the picture below shows the motors setup, but watch the video at the bottom of the page to get a clearer idea. Physical characteristics: Length: 42cm / 53 studs Width: 23cm / 29 studs Heigth: 18cm / 22 studs Weight: 1,2Kg (with batteries) Functions: - Independent suspension on all wheels - Remote-controlled steering - Remote-controlled drive on the rear wheels: RWD Miscelanious aspects: - The final gear ratio from the XL motors into the rear wheels is 1,4:1 (my fastest alt model so far for this set). - The front axle ground clearance are 4 studs, and 6 studs on the rear axle. - Batteries can be easily swapped from below on this one. - The green button to turn on the PU hub is easily accessible on the driver's cabin. Check some real pictures below and the video at the bottom of the page: Feel free to share your thoughts. As usual, for anyone who fancys building this MOC, the instructions are available on my rebrickable.
  10. This is an alternative model for the set 42109, as the name implies, it's a sport cabriolet. As a MOC & alternative model creator, i'm always looking to get some more parts, i needed additional Powered Up components and a few select pieces which happen to be available on the set 42109. So i looked at my local second-hand store and found one in mint condition at a good price. I bought it for the pieces, not the model itself, anyway, out of curiosity, i checked the internet for alt builds and was astonished that a set that came out almost two years ago only has a few alternative models. So i needed to make my own contribution and created this racing cabriolet, please take a look and share your thoughts 😊 It features some details like a (non functional) steering wheel, driver and passenger seats, a super basic interior and door handles, things that are not present on the original model "Top Gear Rally Car". I think the bodywork is decent, the model has all the expected details for a car. I don't like the huge amount of stickers on this set, but i didn't want to remove them, maybe this cabriolet could look bettter without them? I wanted to make the rear spoiler lower, but couldn't find a parts combination for that; funny enough, the rear kind of reminds me of a porsche from certain perspectives. I'm using the xl-motor to control the steering, and the l-motor for the drive. Physical characteristics: Length: 30cm / 38 studs Width: 14cm / 18 studs Heigth: 10cm / 12 studs Weight: 730g (with batteries) Functions: - Remote-controlled steering - Remote-controlled drive on the rear wheels through a differential: RWD Miscelanious aspects: - The final gear ratio from the l-motor into the rear wheels is 1:1,29 - Batteries can be easily swapped from below. - The green button to turn the PU hub on is reachable behind the passenger seat. Check some real pictures below and the video at the bottom of the page. Here's a quick video showing how it runs. For anyone interested, building instructions are available on my rebrickable.
  11. This is an alternative model for the set 42099. It's an off-road SUV type of vehicle, i call it "Trail Blazer". While creating this MOC, the focus was on getting a solid performance and i think that goal was achieved: It has a decent speed while at the same time having a considerable amount of torque; the two XL motors are very close to the wheels with just a pair of gears between them for minimum friction, each motor is driving one of the rear wheels. This is not a crawler, but rather a vehicle that can run on a wide variety of terrains, the motors won't stall easily on this one, please watch the video at the bottom of the page to get a clearer idea.Physical characteristics:Length: 39cm / 49 studsWidth: 23cm / 28 studsHeigth: 20cm / 25 studsWeight: 1,3Kg (with batteries)Functions:- Independent suspension on all wheels- Remote-controlled steering- Remote-controlled drive on the rear wheels: RWDMiscelanious aspects:- The final gear ratio from the XL motors into the rear wheels is 1,67:1- The front axle ground clearance are 4 studs, and 3 studs on the rear axle.- To swap the batteries, the SUV needs to partially dismantled: the rear, roof and cabin can be taken out as entire sections for that purpose; this process takes just 1 minute.- The green button to turn on the hub is easily accessible from below the vehicle. Here's a couple pictures of the inside structure: Here are some real pictures and there's a video at the bottom of the page showing how it runs. Feel free to share your thoughts on the comments section! For anyone interested, the building instructions are available on my rebrickable. Thank you!
  12. I read somewhere that resistance is due to the lubrification lego added inside the hubs, but i don't know for sure.
  13. Thanks! Well, i wouldn't say they have a considerable resistence, but there is definitely a little. I believe it ends up not making much of a difference once the buggy is running.
  14. This is an alternative model for the set 42099. It's an off-road buggy type of vehicle, i call it "Sand Runner". For this MOC, i wanted to find a balance between speed and torque, the end result is a final gear ratio of 1.62:1 which allows this big boy to run reasonably fast for its size while still capable of overcoming small obstacles and a variety of terrains. It obviously isn't a crawler, so, moderately inclined slopes or very rough terrain will stall it. This was also my first MOC using Powered Up components, i must say i miss using physical buttons to control it and have some difficulty using the smartphone screen, it's also trickier to record footage. Physical characteristics: Length: 39cm / 49 studs Width: 31cm / 39 studs Heigth: 18cm / 22 studs Weight: 1,3Kg (with batteries) Functions: - Independent suspension on all wheels - Remote-controlled steering - Remote-controlled drive on the rear wheels through a differential: RWD Miscelanious aspects: - It's RWD, the final gear ratio from the XL motors into the rear wheels is 1,62:1 it's a bit on the fast side but can't take on big slopes or very rough terrain. - The front axle ground clearance are 4,5 studs, and 6 studs on the rear axle. - The batteries can be easily swapped from below, only two liftarms need to be removed. - The green button to turn on the hub is easily accessible through the driver's cabin. For anyone interested in seeing how it runs, a video is available below, and the building instructions are on rebrickable. Feel free to share your thoughts.
  15. Let me start by saying this MOC was not created from scratch, it was built on top of my freely available MOC "Power Functions Chassis", which is a budget RC chassis using just 86 parts. I wanted to show that even very simple chassis can be used to build interesting and detailed MOCs. When i started building i wasn't sure what type of car i would be creating, just something i haven't done before, so things started leaning towards some kind of muscle car; since i'm not an expert at this matter, i had to do some research and find what features distinguish this specific kind of car. This MOC is extremely compact and remote controlled using standard Power Functions components, this means the space left for details is very limited, anyway, i was able to implement a select number of details which are recognizable features of a muscle car, hopefully they are enough to make the MOC look like a muscle car: - A large body; the car is wide enough i think, but it should have been longer i guess (this may be a limitation from using the chassis as a starting point). - Hood scoop; the name says it all. - Side pipes; not all muscle cars have them, but this one was easy to add, so the exhaust is represented through the use of side pipes. - Fastback design; once again, not all muscle cars have it, but was very convenient to implement (to hide the battery pack), so here it is. Other trivial details include the driver and passanger seats, steering wheel, side mirrors, front grill, headlights, tail lights, front and rear bumpers. Since it is an RC vehicle, the only functions it has are the motorized driving and steering. It can be turned on or off from below through the use of a liftarm connected to the battery pack. If you check the chassis page this MOC was built upon, you'll notice the steering is powered by a servo motor controlling a rack; and a single PF l-motor is driving the rear wheels with a 1:1 ratio and no differential; for this MOC, i modified this section, making the l-motor drive just one rear wheel (to facilitate the steering) with a gear ratio of 1:1.67, which makes it really fast, but can only be played with on smooth floor and no slopes. Race version: The fact of having no differential and just one of the rear wheels pushing the car may put some people off, because of that i created a "Race" version of this MOC, which features a rear differential powering both wheels of course, as such, the gear ratio also changed to 1.4:1, lowering its speed, but increasing the torque, so this version can take on slopes, it also has a different color scheme and slightly different aesthetics. For anyone interested, the building instructions are available on rebrickable: the original version has 435 pieces spread over 63 steps, and the race version has 441 pieces spread over 62 steps, so you will be connecting an average of 7 pieces per step on either version. What does the community think of this MOC?
