42131 CAT Dozer outdoor experience
KirTech LAB posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi! I'd like to share some thoughts regarding a winter test-drive of my 42131 CAT D11 Dozer. The first indoor tests left very good impressions, and I was excited to try it outdoor. I still remember a short video from the official LEGO website, were the 8275 Dozer pushes snow (it was about 15 years ago :)) The set isn't new, I tried to find something similar here, but without any results. Sorry, if this topic has been already discussed. - Let's begin with the most important function - a motion. It works very well indoor, especially on a soft surface, but for moving in snow grousers are too small. Of course the model can push some amount of snow but it tends to stuck and skid. Some additional beams on tracks will improve the situation. - As we know, the blade elevation in a stock model works extremely slow, I tried to solve this problem by replacing gears near the actuators. Instead of 12:20 reduction I've done 20:12, but the system even couldn't complete a calibration, so I ended up with 12:12 ratio. But in outdoor conditions (it was pretty cold) it didn't work, probably because of accumulators voltage drop. So, during the test-drive I couldn't change the elevation at all. And as a result, I also didn't use a blade tilting mechanism. - Of course, the ladder mechanism works perfectly in any conditions :) - And the last function - a ripper. If we follow building instructions of the set, ripper won't even touch the ground, so it's necessary to change its connection points. The ripper works very well in loose snow. It would be cooler to have three teeth instead of one, but there is a risk, that it will be not a ripper but anchor, because of low tracks friction :) So, without any modifications the model has pretty low performance in snow (yes, I'm spoilt by BuWizz and buggy-motors). But I had a lot of fun during these tests, you can check the dozer in action: Thanks for watching! -
My first time not mine MOC review. As fan of 4x4 cars I can't miss oportunity to build this MOC by Sheepo. It is not huge like other Fernando's MOC's. So I am in! I decided to do it with shortest and smallest version (I am lazy and busy simultaneously) - 90 inch version. I split my review to 5 parts - 5 separate videos with comments, close ups and so on, cons&pros. Turn on youtube subtitles - they are english! If you are busy to watch all 5 episodes, I advice you to watch the last - 5th epsiode. I will start from it right now. Epsiode 5. This shoud be in the end of the post, but I am afraid you can't go till the end. My vision of Defender: Ultimate offroad machine, well result is not ultimate, but at least looking like that (I hope). I have to solve some weak points of original MOC. Model lost some its pros: gearbox and realistic axles. I have to reinforce chassis and transmission for high load purpose and increased weight of detailed model. Unfortunately, cant make Land Rover unkillable as my Toyota FJ. But result is lovely, Defender will take its place on my "untoucable" shelve with mechanical MAP chassis. many photos of this version is here You shoud know, that MAP - is modular all-terrain platform. And all LR body verison based on this customizable modular chassis. Episode 1 is about chassis Then I have built Defender 90 body in yellow color. Almost STOCK. More photos. I have too much of this color, and construction machines - is not about me. So this LR is good oportunity to use all yellow parts for Camel Trophy style MOC. Episode 2 is about Defender body and small modifications I did with it. Episode 3 is about outdoor test drive. Then my viewers ask me to compare LR with its all-time real competitor - Toyota Land Cruiser. I have several ready to go Land Cruisers on my shelve. So, that was easy for me. But it was not easy to compare this MOC's, since they are completely different inside... Check my episode 4 "DEF vs LC" all photos can be found here http://www.bricksafe.com/pages/rm8 -
The Reaper 4x4 (Outdoor test)

Hi Everyone! Here's the outdoor test I "finally" recorded today after a long wait. Very happy with the results, performance was amazing especially on slippery rocks at 6.30am! Enjoy the action! ( Kookaburra sings during one run, and I pause for it, if you have never heard one before listen out for it) :D Based on Tim Cameron's Showtime
