    They both look so cute yet they have great performance. The tires on the red truck seem very similar to what the new Xerion tractor set tires will look like.

    Thank you! I certainly am glad you are building JJ2's Super Crawler. It seems like a lot of fun to build and drive! About the LXF... I have been rather busy lately and because of that and my lack of skill when it comes to building in LDD, I have not yet completed the LXF file. I will work on it tonight and hopefully complete at the very least an axle or so. Thanks JJ2, The tires are labeled as being 1.9 inches, but in reality the inner ring of the tire is actually about 1.8 inches for a tighter grip on the rim.

    At first I was considering the hot flame. This was until, however, I realized that the hot flame sets have RC units that DO NOT have the secondary, auxiliary output. I just figured that the 8475 had everything I wanted plus the auxiliary output for extra motors/functions. But thanks anyway!

    Thanks for the replies, I have gone with the 8475 Buggy! I am also happy to announce that I plan to make a review of it, perhaps the first of the 8475 set on youtube! (as I cannot find any ). Now I must wait for my order to arrive.....

    Thanks. And to everyone else, I agree. It seems that the 8366 has more pieces and is therefore more useful.

    Hello All, So I currently have two RC Buggy motors and numerous PF elements. I want to purchase one of the older Technic Racers sets with the entire RC system included. I have narrowed my choices down to the 8475 Race Buggy and the 8366 Supersonic RC. 8475 Race Buggy - Has a great array of shock absorbers including 4 soft 6.5L shocks in red and 2 hard 10L springs in red. - Has rare tires in an ideal size for some of my builds 8366 Supersonic RC - Has a decent amount of tubes and hoses of which I have few - Has tires that I do not have - Is more popular and therefore there are more Supersonic RCs available to buy Please let me know of any suggestions about which one I should or should not buy. I am very open to new ideas! Thanks P.s Just making sure, the 8675 Outdoor Challenger does not have buggy motors, correct?

    Nice job. It has a great body and nice articulation. Also, people often make offroaders with the larger unimog or 9398 tires, of which makes seeing an offroader with these tires a nice change. Also, great minifig scale!
  8. PunkTacoNYC
    Thanks, that means a lot. I totally agree, a motor like you said with two axle holes on either side would be SO useful. Very similar to the servo motor. It could even be like an extremely geared-down and more efficient buggy motor.

    Haha, if only.

    Thanks so much, I do plan on making a lxf (ldd) of it soon, but not sure how long it will take. I'll post here when it's ready. Also, I was thinking the exact thing about the new tractor wheels. They look great and possibly even bigger than the Unimog tires. Something tells me, however, that they will be very stiff, which may not be ideal.
  11. PunkTacoNYC
    Thanks, it always takes me just as to pick the music as it does to make the model itself. (Or at least that's how it appears in my mind ) Thanks for all of the comments guys, they are really great. I was thinking of making an lxf file of either the front axle, the rear axle, or the whole truck.
  12. PunkTacoNYC
    Thanks guys, the responses are great. That's exactly what I was hoping for.

    Thanks, and I too love my blocks!

    I present to you my Lego Technic Chilli Crawler! This is a complete makeover and overall improvement from my previous Carrot Crawler: http://www.eurobrick...howtopic=112037 Yes, I know. This is the second crawler that I named after a vegetable; expect more! Features: - Triangulated 4-link live axle suspension using 4 soft, black shocks. - 4x4 with one PF XL motor mounted parallel* to each of the two axles. A final gear ratio of 1:5.001, yes this may seem slow, but the enormous Super Swamper tires make up for it. - Speaking of that, 4 RC4WD Super Swamper tires. No, they are not Lego, I got them from a nearby hobby shop. - One L-motor for steering in the front axle, geared down via worm gear to 8 tooth gear, then a 12 tooth gear to a 40 tooth gear. The 40 tooth gear drives another 12 tooth gear that moves a 13L gear rack. - Portal hubs for all four wheels. Standard Lego Unimog for the rear axle for rigidity; custom triangular plate portal hubs on front axle for a steering pivot point closer to the center of the tire. - Good articulation, about ~55-60 degrees. - Controlled with an SBrick. - Powered by a Lego rechargeable LiPo battery. - Green Chilli Stem** * The mounting of the drive motors parallel to the axles was a must for this crawler. By doing so, I have not only eliminated gear slippage as there are no perpendicular gears, but there is also a ton more ground clearance in both the front and rear axle. The rear axle especially as the motor is actually on TOP of the axle. Crazy, huh? ** Makes the crawler look so much cooler. Challenges: - As with all 4-link suspension setups, the mounting and placement of both the links and the shock absorbers proved to be a rather annoying, tedious part of the process. I have, however, managed to make a VERY rigid triangulated setup where the shocks are not bent or warped in any way. - The mounting of the two lower links on the front axle was also difficult as there was virtually nowhere I could mount these links onto. I was able to (somehow) securely mount both the lower links and the shocks of the front axle onto 7L and 9L beams on either side of the motor. - Mounting the motors parallel to the axles proved to be hard, but actually somewhat straightforward when it came to the rear axle. I had been so used to having drive axles perpendicular to the axle like on my previous crawler. The mounting of the front drive motor was difficult in the fact that its power is transmitted through various gears and the motor itself is connected to the axle by two plate beams and a pin or two. Although the front drive motor is still not completely rigid, I have had no problems with gear slippage whatsoever in either axle. Some pictures: And finally, here is the youtube video: I welcome any suggestions or comments you may have. I will, however, say in advance that I DO NOT plan on making a body for this crawler as I designed it for performance purposes mostly, a Lego "comp-crawler" as you may call it. Thanks, pt

    I have to say, that looks like a great chassis from here. Nice proportions, good axles, you know your stuff! Somethings to consider: - The 4 parts where (I assume) you plan on putting shocks, you do plan on putting springs on the axles, correct? If not, I suggest soft 6.5L shocks, you may need to change the mounting position and braces. - In terms of propulsion, I would recommend an XL motor for more serious offroading i.e. rock crawling. I would recommend a Buggy motor for a faster, more trophy baja type offroad truck. Unfortunately, it is rather hard to get both speed and torque with lego motors without the use of a solid gearbox. - It also seems that you already have a plan for a working engine, of which would be powered by the drive train. Seems like you have a really solid plan, just keep in mind, Legos are made from plastic, so simplicity is key in terms of limiting weight, gear slippage, motor efficiency, etc. Good luck!

    Nice job, and here I was thinking your first version was the best mini crawler I've seen! It handles the snow surprisingly well considering the slick tires you added. It even looks better than the last one.
  17. PunkTacoNYC
    Nice crawler, probably one of my favorites due to its small size and simplicity. I think its great that you managed to use a single L motor. Your axles also seem great. Good job.
  18. PunkTacoNYC
    Hey, you can definitely use what you already have. Depending on the size, an XL or two XLs will do the job (note that XL motors, as powerful as they may be, are somewhat underpowered when it comes to speed). You can use one of your M motors as if it were a servo with one of these systems: http://www.eurobricks.com/forum/index.php?showtopic=54104. And finally, for the gearbox, you can use your other M motor for the gear shift via a worm gear, linear actuator, or pneumatic pump. I suggest the worm gear with - if possible - a white 24 tooth safety clutch gear. Good luck on your build! P.S. about the XL motors, if you want your creation to have good speed without using a buggy motor, you are going to want your car to be rather small with preferably two XLs. Yup, two. Here are two points for reference in terms of the relationship between size of the model and propulsion needed: http://www.sheepo.es/2011/10/xr7-mini-rally-car.html and http://www.sheepo.es/2014/03/axr-400-crossbone.html.

    Yes, I agree with many of the previous comments. I had this set and I also considered 4x4ing it. Unfortunately, you will not be able to simply add the powered axle to the front wheels, you would probably have to completely rebuild the front suspension. If you are already going through the work of rebuilding the front suspension, you may as well reconfigure the entire truck to live axle suspension as seen here: http://www.eurobricks.com/forum/index.php?showtopic=112037. (sorry for the self endorsement! ).

    Wow, awesome mocs with even better bodies! I really like the front suspension on the truggy. I do wonder, however, if the gears that transmit the power from the L motors to the wheels are properly braced enough. It seems somewhat fragile. You may want to consider connecting the two wheels to one single, solid axle. Nice job, keep up the good work!
  21. PunkTacoNYC
    The tires dimensions are: -Circumference: 36 cm -Width: 5 cm -Diameter: 11.5 cm About the size of the crawler, I have actually completely redesigned both axles. I will be posting photos of these very soon... I have not tried this yet but will soon. Here is a comparison of the Super Swampers to the Unimog tires: Thanks! But what exactly do you mean by using beams for a low simple body? Could you give me an example?
  22. PunkTacoNYC
    The tires are not Lego but are rather from here:http://store.rc4wd.com/Interco-IROK-19-Scale-Tire_p_1423.html. The rims, however, come in many sets and I got mine from the Technic 8110 Unimog.
  23. PunkTacoNYC
    Thanks! Oh so is the pinion support the yellow piece in front of the gear? Is it secured to the chassis? And is the shim behind the gear a lego piece? If so, what piece?

    Hey, this is my first post on Eurobricks so if there is anything that I am doing incorrectly in this post, please let me know. I am presenting my Rock Crawler, or more specifically, my Carrot Crawler. Features: -Triangulated 4-link suspension using the Lego soft shock absorbers. -One PF XL motor per axle (a total of two), each geared down 1:2.779. -Custom portal hubs for each wheel. -Ackerman Steering with slight caster angle powered by PF M motor geared down 1:3.333 including a worm gear. -Rechargeable LiPo battery box as power source. -Controlled by a SBrick and an iPhone 6. -RC4WD 1.9" Super Swamper crawler tires. This has been a work in progress for a long time and I feel that it is finally polished enough to showcase on the Eurobricks community. My plans for fixing and editing this crawler (Some of which, I have already begun working on) include: -Building a better chassis (the angled pieces on top of it don't REALLY fit, but I made them fit! ) -Eliminate gear slippage caused by the perpendicular bevel gears. -Mount the XL motors parallel to the axles which would both eliminate gear slippage and provide more ground clearance. Here is a picture: And here is a video: Please give my any suggestions for my post and more importantly, my crawler! Thanks

    Nice steering, similar to mine, just smaller.
