  1. Hi, my son is playing pullback cars for some time and when he's bored I'm trying to rebuild something to get more fun for him and also challenge myself. Here's 42072 B model done using only parts from the box (including extra parts). It's pretty fun to play with this sets due to very limited parts. Here's .io file (Stud.io from Bricklink) http://fantasygames.com.pl/lego/42072-model-B-ctan.io 12787C01 LEGO Pullback Motor 6 x 5 x 3 - it's made out of bicks because there is no 3d model. And here in real life together with A model:
  2. Hi! That is my entry for the new contest: a tractor mixed with a dragster with a cartoon style! I amplified the shapes of a real tractor: I put huge rear wheels compared to the frond ones, there are 2 big headlights on the front of the hood... The only fonction of this MOC is that it is powered by a pull back motor. (Also, you can move the spoiler because it is fixed with a pin with friction, but that doesn't upgrade the playability) The anti-roll bar has a real utility. Without, the tractor finishes on its roof. The shock absorber is really useful: without, at the acceleration, the drive wheels "jump", they are not in contact with the floor anymore, so the motor is not used at 100%. So actually, the tractor does wheelies smoothly. That's all!

    MOC - Lego Clockwork Locomotive #3

    Hi all, after the arriival of BBB wheels, I finally completed the third clockwork locomotive. It is based on pre-war Goods Train No.2 made by Hornby Thanks to BBB wheels reduced profiles it manages well large curves. It works also on R40 radius curves, but looks a lot better on longer ones. The clockwork motor is quite the same as my previous version, only a bit lighter and made all in dark-stone grey color. Two pull-back motors are connected by two red 40-tooth gears, which power the rear big wheels. Motion to front big wheels is achieved trough coupling rods. It has no brake lever, since for winding up you need to keep it on one hand and you can stop the wheels with your fingers. So, being an unuseful weight, I did not include it. It is very light, since the boiler is made by empty cilinders and the body is made by panels. Gear ratio is 5:1 to the axle, then large wheels help to furtherly overdrive the gear ratio. I choose 5:1 since this locomotive will be part of a set, and needs to pull three very small and light wagons. The bolt works as flywheel, and it is put over a little piece of flexible Technic tube. No wheelspin at all allows a bit more travelling. Front wheels on bogie are completely independent, so they make less friction. Front bogie is made to follow the track and not to guide the locomotive, as in old Hornby models. On a mixed track made by straight and large curves it can manage 9 meters with a pair of wagons. I plan to replace the full coupling rods with @zephyr1934 ones, since they are much nicer and surely lighter than mine. Hope you like it! Davide

  6. So when I read about TC13, I first had something huge in mind... But actually I think the pullback series are cute because of what they are: small, simple and quite fast. So I decided to keep in the spirit of official pullbacks, and keep it small. However, I did not go for the obvious racer or offroader car, I want to do something not done before (at least not by TLG). So I went for a helicopter. The type was not a difficult decision: after watching barmans incredible avatar helicopter numerous times, I wanted to do one myself. So how to make a pullback work without any wheels... Here is the proof of concept result of tinkering an evening with two pullback motors and some rotors: And a video of it in action. I'm actually quite happy with the way it works, although it does not use the full extend of the windup mechanism. So I'll stay with this concept and try to refine the looks in the coming period.
  7. Pentagon Clock This is a wind-up pendulum clock powered by two pullback motors. This clock is not true to real time but rather focuses on features such as a wind-up mechanism, pin wheel escapement and three concentric hands. It has been built completely in-system and can be reproduced without any fine-tuning, except for making all gears run smoothly of course (LXF-file here). The clock has a very consistent autonomy of 18 minutes. It features: A wind-up mechanism - A differential is used to prevent the hands from running counterclockwise when winding-up the clock. One of it's outputs is locked by default and slips during wind-up. Pin wheel escapement - Instead of using teeth, the escape wheel has three round pins that are stopped and released by a scissors-like anchor, which has been integrated in the pendulum. Three concentric hands - Planetary gears and a differential house make for a fictitious LEGO time system with 2 hours in a clock revolution, 5 minutes in an hour and 30 seconds in a minute. The pentagon-shaped clock face refers to the 5 minute hour. All features have been originally developed for this contest.
  8. I have one of the old pull-back motors, which, as @Aventador2004 noticed, unwind really, really fast. I quickly realised that if I wanted to build anything but a car, I needed something to let it unwind in a controlled manner. For example, an escapement, like in a clock. Unfortunately, @Didumos69 posted his topic while I was working on my proof-of-concept. I guess there's no rule against having the same idea, but I'll think about if I want to build a clock or something else from it Anyway: here's a proof-of-concept to show that the idea works. I shamelessly borrowed one of Ben van de Waals escapements (W40, https://www.youtube.com/watch?v=e-dXJJ-aJ60), which works great. Now to figure out a ratchet mechanism to wind it. To be continued PS: sorry for the filming-through-a-vertical-mailbox-opening, but my phone was the quickest way to get a quick video and I still don't know how to use it properly If anyone can tell me how to change the aspect ratio on the iPhone, let me know.
  9. Hello everyone! I watch a good party out here. I could not resist and also decided to take part in a race Truck. The model only took 419 parts + pullback engine. For better visibility with a racing truck, v-12 is being installed by Paul Boratko (aka Crowkillers). Heavy-duty front bumper, large rear spoiler and huge chunky tires.

    [TC13]Roadster 2

    Here's my entry model for the TC13 competition: It was inspired by the real life Tesla roadster 2 both aesthetically and mechanically. The model uses 3 pullback motors in the following configuration: As you can see the rear two pullback motors power the wheel directly for best possible acceleration. BUT the front pullback motor is geared up. This additonal gearing gives the model a higher top speed and a greater range, which is a technique I have yet to see on any other pullback cars. Around 30 panels were used to give the car it's very smooth, organic shape. Notice the small yellow rubber band used to keep the front part tightly together: There is enough room in the back of the cabin to fit two or three small human beings: The rear boasts a difusor and a small spoiler in the back, just like the real thing: While this is one of my smalles models to date, I am very pleased with how it turned out. The shapes are very smooth and organic and the fact the car drives mere milimeters above ground, give it a very sporty feeling. Video coming as soon as I find enough space to run it

    [TC13] Pullback Motorcycle

    Hey everyone! Today I'm presenting my TC13 entry, which is a pullback motorcycle. I actually built it before Christmas but I was never in the mood to show it, except for the holiday version on my YT channel. I don't think it qualifies as a café racer or a dirt bike, so I'm just calling it a motorcycle. It was based off of this: I'm not a big motorcycle person, so I don't really know what type this is. Here are some pictures. As you can see, the motor is connected to the back wheel by gears. The front wheel steers, and both wheels have suspension. Thanks for reading. Tell me what you think!
  12. My Lego Traxxas Slash is a short course truck based on my Lego Technic Pullback Truck with suspension. The chassis is nearly identical - but I redesigned the suspension setup, incorporating a smaller shock absorber with a custom linkage enabling extremely long travel of the rear suspension. I modeled the styling of this truck to the popular Traxxas Slash R/C car. The traversely-mounted V6 engine is non-functional - HOWEVER, you can adjust the pistons into 36 different positions to your liking by turning the 36z gear.

    [TC13] Sprite

    Yesterday i had an insomnia, and i decided to make something for TC13. Actually i finished with my "Sprite" at all. But now i want to show my progress throught the night. Core idea - to make some funny jdm-style car with stance. Now it looks little bit different I have to make a video and make an entry post.
  15. First I wanted to build some windup mouse, but, when I started to put something bigger, it became more like rat, or even some capibarra by the size. So abondoned this idea. Now I will try to build something like Tyrell Not shure about rear axle rigidity, but looks good :) . Front axle is "floating", so that front wheels are in contact with ground. two times tyrell because

    [TC13] Formula One

    Hi there, Please see my Formula One equiped with a PullBack motor. The full sized pictures on the following page : https://photos.app.goo.gl/xWePdNMTOR95j3eC2 Presentation movie : Enjoy !
  17. I have a single copy of the latest version pullback motor. I'm using it for my TC13 entry, but since today it seems to behave differently. When I wind-up the motor it sometimes gives a lot of friction and it seems to give less power when it unwinds. I did over-wind-up a few times (it clicks unhappily when this happens) and I'm curious whether this could have do everything harm. So my question is, is this common behavior for a broken pullback motor, or not?
  18. Hi Eurobricks member Here is my entry for Eurobricks contest It’s a pullback airplane Functions: As all the pullback, when you moved back, the engine cheers up itself. When you left, wheels and the propeller turns The video: http://youtu.be/ERiFm_HnOOY
  19. For my entry, I decided to make something nice and simple... And this is what I cam up with: It's a wind-up motor inside a 6x6 box, that moves the legs of the Technic guy, creating the illusion that he is pushing the box. Video: As mentioned in the video, I have also made instructions for this, which are available for free on Rebrickable. POV-Ray render: Some LDCad animations - rendered with POV-Ray:
  20. After the creation of my Compact Pneumatic Excavator, I decided to make something small, then am going to make something huge (no hints). The small project was easy, and quite a fun vehicle too, the Stadium Runner! My Latest creation: Pullback motor. A fun to drive, easy build pullback. Like always: Thanks for looking and please drop a comment!
  21. Hi, I noticed there are not a ton of pullbacks on this site, so here is mine: I tried to make it like a official Lego set, and color vomit. If it was a set I would include barriers like in this picture. instructions: https://bricksafe.com/pages/aventador2014/barrier-racer-
  22. I built this Lego Technic Pull Back Truck with rear long-travel suspension about a year ago and just got around to filming it now! Two pullback motors drive the rear wheels and off-road tires! In this video, I simply go all action with the editing and test this Lego Pullback Truck in the elements! Please let me know what you think about the editing =)
  23. Hello there! After roughly four months, I have finally scrapped together time to make another LEGO video. But this time, I decided to try something different and take you behind-the-scenes of the original video. In this vlog style video, I show you how I was able to create the various shots I did with a custom LEGO GoPro mount I found online and modified to fit onboard my simple Lego pullback car. I even built a Power Functions motorized camera dolly with steering abilities to film turntable style shots. Please watch the video and share your thoughts on my new editing style and attempt to raise production quality. I plan to begin adapting a series to this style format/editing if I get enough positive responses. Also, if you have ANY suggestions on how to make my videos better, PLEASE share them! I am always looking for ways to increase the production quality of my videos, and without feedback from viewers such as yourself, I will never know And yes, I will get rid of that lame intro.

    The Pullbacks: Series 1

    Hi there! I have created a fleet of pullback cars for an event and wanted to share them! Here they are: 1. Mad Buggy A simple pullback buggy with suspension (and too many curved panels on back) 2. Arctic Speeder A fast arctic vehicle meant for rapid transport in sub-zero temperatures. 3. Future Car (airfoil up) A car of the future that has a spring-loaded airfoil in the back and opening doors and hood. 4. Rocket Rod Kinda ran out of ideas... Very fast though! Hope you liked it!
  25. Here in the UK we have a bank holiday coming up. In case you were looking for something to build, I have recently finished creating 4 C-models from sets 42026, 42046, 42011 & 42060. The first two were inspired by set 42010 (dirt racer), the second by the record breaker pull back and the pair of motorcycles by the double snap with hole which reminded me of the front forks of a motorcycle. As I've disassembled the models I've taken pictures so you can build them yourselves. Visual instructions are on bricksafe.
