Umm....back at 'ya.... My comment "no one gives a rip ...." was referring to your exhibit of how much you pay for all your hobbies. It had nothing to do with the cost of this set. Which yes, does fill up 75% (or more?) of this thread. An exhibit of how much folks pay for all their hobbies.....not so much.

Holy cow guys...this thread has already been closed once because of detractors. No one gives a rip about how much you pay for things... Honestly, I look forward to the day where we can discuss a set because of its technical or aesthetic properties... not 75% of a thread that is hundreds of comments long about a set's cost.....

To each his/her own I suppose. I loved the movement and motion along with the music. I could have watched more! Others seem to agree!

Perfect. I will get to it. This is one I see myself really doing in the future, and as can be seen in my latest thread, I eventually get around to all my commitments, even if it's years later....

Here is the last video of the series. The Chili vs. The Bully Not overly scientific; the upshot here is that gearing that does not allow the vehicle to roll backwards makes all the difference. Gearing this so low that the motor would not turn while on a steep surface allows for better driving and handling. The Chili handled everything the Bully could despite much less power and a shorter wheelbase. I did test the Chili with smaller, 1.9 RC tires and it was not even close to making it up "the obstacle" - I am not sure if this was due to the tires per se or the fact that the gearing was not sufficient to stop it from rolling backwards. An interesting test would be to change the gearing of the whole Chili so that it was geared down sufficiently to not roll backwards but not need the planetary gears inside the hub and use the smaller tires. But, I am afraid I won't get to that. I am afraid this project, aside from driving outside, has exhausted itself. Here is an old picture of the Chili when it was actually taken outside: Here is an updated photo of the Chili: The results were actually surprising to me. I knew the Chili was lighter, and had a smaller wheelbase, and thought that would make the Chili unable to make some of the climbs the Bully did. However, despite these shortcomings once the planetary gears were added the Chili kept up just fine. This will be the last video inside. In a few months when I am healed perhaps I will try this comparison for more rigorous testing.

Yes... this is beautiful. Old PF motors and BB. the movement of the shovel arm and bucket are beautiful. Good choice of music to the video..... good perfect with the functions movement..I could watch this for hours....

Well done. Smooth operation. Love the color, makes it look so genuine. Thxs for sharing!

Yes. Big fan.

There is already a post about this guys. If you have comments regarding posting style, lets post there where @sariel's comment style was a frequent topic. This thread is about 42131.

Looked at your crane again and realize I never responded. YES! If you have the CAD file, even if it is only 75% finished I would be interested in seeing it. I would like to see if I can fill in the rest and build this (little) beast. I have build the Grove with the 62 mm tire, my own version with the 49 mm tire, a seven-axle 42009 (back in the day) and a multitude of other Lego cranes. I even have the die cast model of the LTM 11200 so building this would be interesting to see the different techniques, etc. I actually will keep my GMK6400 and it would be cool to take pics, etc. comparing both at this scale. Lemme know if you still have it and can share. Again, great model!

Great scale. WONDERFUL functions. All-around quality submission.

Thank you and yes! Torque is crazy on this machine. Perhaps even more daunting was nearly at the exact same moment (2:34 - right before the rock breaks off) the back right wheel is stalled. That wheel is powered by its own L PF motor, geared at 12:1. THAT is a crazy amount of torque for ABS to handle and obviously it handled it just fine. Actually, I had no problems with the U-joint. They did not crack, etc. In fact, the original model used a L motor, I think a M motor works just fine. Five L motors on one BuWizz is pretty demanding, so I thought if I could decrease that demand just a hair it might be a good thing. Steering worked just fine - and as I mentioned before, I was fairly abusive to the steering. Used steering into the "rocks" every time to press tires into obstacle. Yes! That is right! Bubba Bacon and Tim Cameron! Thanks for the comments.

Admittedly this post did not get much traffic. Except for complaints on the original font But I suppose this is what one does after leg surgery and cannot get access to his/her total parts collection for a real build.... and to keep one from going crazy from sitting/lying down. But I can still crawl lol.... Here is another video with the Bully Crawler. Increased the size of the "mountain" considerably. VIdeo shows several features...... the outstanding ground clearance of this crawler, i.e. I was able to mount a GroPro underneath and keep it there for an entire climb! (3:47) and also its ability to climb a roughly 50 degree slope (2:22)... which is noteworthy when the slope is all LEGO (ABS not really ideal for climbing. Smooth, plastic surface). I love this crawler. Will be keeping it. Can't wait for the leg to heal and to try this thing outside. One note, and surprise actually... is how robust this thing is. I was going to add a blooper video and show how many times I accidentally drove this off my "mountain" all with no damage. Also, one can see that once it makes it up the climb, going down is nearly more treacherous. The vehicle stretches out, bending the trailing arms to their max, and they persist and remain intact every time. Because of the extreme slope angles going down, often there is some sliding and hitting the bottom hard. Axles never broke or failed. Fun, great build. Next I will be comparing the Bully Crawler to Punk Taco NYC's Chili crawler. Stay Tuned!!

I don't have 42100 but now I want it.....

Aliexpress?

They are not official Lego tires.

Looks great! I am not sure how I feel about the older tires, but sure like the your 'Mog with the updated tractor tires.

I was just looking at your 'mogs the other day on rebrickable. Great stuff. For some reason the photos links don't work for me. Is there something wrong with them?

Well said. There are just so many opinions, likes, tastes, etc. out there. I agree wholeheartedly. I already said my piece about the contest. I'm not sure I was ever really into this one at all. That being said its not about me or my opinion and although this contest was not to my liking I can certainly appreciate the time, effort, and even $$ (Jim) that went into it. Thanks alot @Jimand @milan for running this contest and all you do on this site. Great contest overall and it helps boost involvement, activity and overall fun! Your work is recognized and appreciated! Also, just something for folks to think about. Many of our newer members may have not been around long enough to see, or even be a part of dying Lego-sharing sites (*cough* mocpages *cough*). Well I have. These sites take time, effort, resources.... they don't just run themselves. And if there aren't those willing to sacrifice their time, etc. then the sites just die. Sharing opinions, critiquing other's work, etc. are all well and good.... no one is disputing that. But tact is important to remember. One may not want to come and just vomit criticism (not pointing a finger at anyone or any one comment) all over the place without thinking about presentation. Biting the hand that feeds you is not the way to go lest that hand stops its feeding. Mocpages is a good reminder of that....

Normally I would. But if I'm reading the room correctly these are not guesses.

You should really get to know the members of the forum more before you make such strong comments yourself. @erictrax and @M_longer are very reputable builders, especially with these kinds of builds. They would not be stating things the way they are without inside information.

I see on your imgur page that instructions will be uploaded on rebrickable. I for sure would love to build this!!

Great. As I experiment myself, not with this set but with other crawlers this is very important for climbing...

This is a great Lego room! Not sure how the "F*#$ o#*" sign plays in the overall theme of the room but to each his own.

Another analysis that I would be interested in, but have not done is the relative amount of pins in a set to other pieces. In these large sets there can be large variation in pin-to-other-pieces ratio. Or a lot of redundancy. Like 42155. Many thought this set was a great value for the money. Not saying it wasn't, but there was tons and tons of redundancy in that set. Beams, frames, pins, etc. Sets like this should (I say with some hint of sarcasm) be relatively cheap for TLG to produce. Still my all-time favorite example of this was Lego 8288. If I remember correctly, it had one of the all-time lowest PPP value (even considering inflation). Also one of the least unique sets of all time (defined as total pieces/unique lots). Tons of thin liftarms, tons of regular liftarms, throw in some pins and tracks and poof! you have 8288.
