agrof posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingHello All, hereby I present You the King of the Pull-Backs, which for I had the idea for very long time. Teaser picture is coming: Where has it started? Well, I had these parts lurking around, and really wanted to test them together: Recently, while I was playing with my Mini Suzuki Samurai, got the idea, how well the body and those parts above would fit together. As I really like the body lines of the Samurai, I decided to keep it, and improve. Let's take a look at on it, the common DNA is quite obvious, that's why I decided to keep it in the Suzuki off-road family, and named as Jimny. I set some constrains for me, like: keeping the body, but reconstruct it using 12M axles for the wheels make it affordable make it sturdy make it fast Here is a picture from inner structure, and how I set the distance with pulley wheels for the chubby tires, and increased the friction for the 12M axle: And one more insight shot (roof is hidden). It was pretty challenging to build a reliable and buildable inner structure for the shape I set in my mind, but finally it works, prototype works and sturdy enough for crashes! The hood still has some flex play, but nothing falls apart. Meanhile the build I made some records for me: Big and heavy wheels have a ton of angular momentum, but 4 Pull Back motors do the job. Big and heavy wheels help to keep the center of gravity low, so it jumps pretty stable. You need extra attention to load both axles properly, but once it is done...whooooooooooooooosh!!!!!! - my 42034 lost the run. (Video might follow, but no promise.) My painting skill (and patience for it) sucks... I want to paint the rims in black, but I have to make a second try on it. I don't find right time and place for taking sharp photos, so I present it as LDD renders, meanwhile I have a built one beside me... sorry. I am also waiting for missing color correct parts (on the way). As an engineer, I wanted to add some extra technical bit first, like suspension, but I realized soon, that it makes the loading of the motors very difficult (as You need to push the car downwards), makes the whole construction very complicated, and adds weight for no reason here. Keep it simple: low weight, big power. BUT, I was smart enough to integrate one nice feature though, and I proudly present You the first Drive Mode Selector in a Pull Back car! HERE You can download the LDD file, I tried to divide the model into small building groups, and built up in the most wallet friendly version. Some parts are mislocated, after real life build, I realised some stress and reinforcement need, but to fix minor placement issues in LDD, I would have to build it again from the ground. We can conclude, that I don't have the patience for it. TO DO: flip the pins (in the side panels) and the 2M rubber damper (under the hood), and push the windshield together - that's it. This is what You get in the LXF file: And finally, some possible versions - I am building the red one. Small part count (284 pcs), great fun. Enjoy! Edit: one small fix in LDD file - v3.31
