Hi, glad to hear that. I have recently finished the 3d data for chassis of the second generation, so instructions are definutely on the way. Hope to finish them this year, but I have many opened projects waiting.

Thanks! Yes, the joystick work well.

@msk6003 Thank you for suggestion. Yes, it might work slightly better.

Update time. In case of emergency, it could be used as finished model, but I would like to fix and clean some sections of the build. Also photos need improving. Regarding the headlights colour - I am fine with Tr yelliw, but using Tr neon yellow might be more true to the original.

@Saruzeufel Thanks! I think that the 12t wheel will fit better, but then the roof will miss some blue elements. It might need som research to find better parts. :D Spring loaded doors would be nice, but maybe too complex for this scale to achieve the correct geometry.

Well, this time it was easier to build the prototype digitally. in near future I hope to build it with real bricks and hopefully avoid BL orders :D Next physical design iteration will also differ slightly from the shown 3D file, because there would be many part collisions during steering, in case it was built exactly like this. I managed to fit inside 3 axle steering and joysitick operated arm, with almost the same mechanism like the original (just scaled down). Still thinking about the fake engine - at least it will have fake fake engine (bunch of tr. clear bricks with yellow accents) Should I go for the HOG knob with the 2x2 round brick, or with smaller 12t gear wheel? BTW, the whole TC25 feels to me like great maketing for all the new tiny panels. :D (not sure if it was mentioned before)

I would like, but can not promise. Steering is more important for me.

Well, after short period of hesitating I have decieded to give this contest a try. I will enter with 8454 in roughly 0.7 (1:1,4) scale. Chassisis just a placeholder, but wheel positions should be final. Main challenge will most probably be the steering, but I would like to reicate at least the opening parts and the watergun operation

@2GodBDGlory Thank you! Yes, the flex frame works good enough for this kind of vehicle. Not sure how it would perform for heavier trucks or crawlers (with deformation comes also the spring-effect when released). about the event - let me answer you with videos from the last (and unfortunatelly only) 2 events from 2017 and 2019. It is real stress test for endurance of batteries and all mechanical parts. In the beginning of the second video (K116) you can see where I took inspiration for this MOC. :D

Hi, maybe you remember the EXP.buggy MOC I have shared some time ago. Well, I alway knew that the chassis have more potential. So, afetr disassembling the buggy body into other MOCs, I kept the chassis and built new body for it. I wanted to achieve the feel of classic offroad/SUV car like LR Discovery, Nissan Patrol, etc. Moore photos: https://bricksafe.com/pages/horcikdesigns/adv-suv INSTRUCTIONS: https://rebrickable.com/mocs/MOC-153020/Horcikdesigns/advsuv-4x4-offroader/#comments The MOC is powered with 2 PF L motors (even in the video), one powering the Front axle differential, and the second for the rear axle. The chassis is very flexible, so it does not need any advanced suspension parts or subassemblies - just front and rear axle connected with 2 liftarms. This has some drawbacks - limited suspension travel (not for crawlers), and below average ground clearance - good for mild and mixed terrain only (as shown in the video). The car was built as test rig for LEGO Technic overland expedition event - thus it was needed to be mechanicaly simple and reliable. And in case you are interested in instructions for this MOC here are some renders of the source file: Hope you like it. :)

Oh, sorry for bumping old topic, but I have finally processed the video from March (photos above)

Wow! Good job. Does each version share the same chassis, or has each of them a unique chassis design?

Oh, glad to see another Praga trial truck being made! Definitely looking forward to see the finished version! I have built similar vehicle some time ago for our local TT event, and the best performance was achieved with HUBs made from big old turntables (1:7 reduction saves many u-joints), they ensure also excellent ground clearance.

Nice custom portal HUBs! Looking forward to see the result. Good luck!

Hi, quick update here. New 3d printed custom fenders, rear lights all lights working with RC control, and new colourscheme. Also did some minor changes under the hood and still tinkering about the rear diff lock.

Wow, good job! I love the fact it is alternate model.

To all who is interested - here is video of this bunch of plastic bricks balancing on the edge of meltdown. :D (luckily, it was quite cold that day) I would like to make another video in future, when the weather will be better.

@gyenesvi@gyenesvi the central L motor is used as winch motor in my 2buggymotor version. However, in order to keep things simple, winch in instructions version is powered by m motor placed one stud higher (it would not fit to the 2Lmotor version. Yes, the front axle has pisitive caster angle. When the susp. arm is compressed it slightly bends the axle (in theory, but thanks to lot of play in the parts it does not affext the performance a lot). I think I mentioned the modified CV joint (not origial LEGO part) . It is because of increasing length of the driveshaft in order to decrease angle when the rear axle is compressed, thus helping with the issue with rubbing against the motors. However, it is totally OK to use the original part.

@Daniel-99 I also considered using Bl motors in rhia MOC, but as the grars and axles are still plastic (without increased thermal ans wear resistance), it was not a way for me. Whats more, rules of the even I plan to attend with this MOC do not allow "non LEGO-like motors". But for some future peojects, I definitely would like to push the boundaries of my experience with this type of motors, but I am concerned with overheating.

@Daniel-99 Thank you! video of the RC version is still only in form of short IG reel (mentioned above and also below), but longer video of driving performance is being prepared. detail photo of intern al wire-mess is hdden in spoilers in original post. https://www.instagram.com/p/Cn9RnIKsh-5/

@gyenesvi - Thank you! - It is very fast, indeed. (there is short video on my IG). Well, I have not considered the driveshaft wobble as major issue, as there are no large angle deviations. I checked it now again, and it slightly rubs the L motor casing only in case the axle is almost fully compressed on one side. As this occurs only when traversing long slope, or as dynamic effect of going over obstacles (and the driveshaft as plastic one is flexible, it is not a major issue IMHO. Using only axle without the connectors that increase torsional rigidity might help too. Wear is not observed, as the car with L motors has only less than 50 meters on it's (fictional) odometer. I agree on the slight messines of the body. but on the other hand, It gives the car the needed personality, IMO. The gray car had older system of panel fixtures while being photographed, today it is iproved yet and will be present in future photos of the MOC. The rims are my own design (inspired by 42110 rims, obviously, in order to look at least little bit LEGO-like), the tires were found on Aliexpress some time before. They have the dimension marked on their side - 7 8/2 5 R /5.5 (76mm OD), I think they come from this link (hidden in spoiler below) They work good enough with the original LEGO rim (43mm), but they look much better on the printed ones, that have slightly simplier internal structure. @Thirdwigg - Thanks! The 74mm tires was probably the missing link in LEGO tire system. They are great for offoaders in this scale. Well, I try to follow some design rules (not all, as @gyenesvi mentioned - the non-connecting or unaligned lines for example). The lime starts to grow on me too the more I look at it. I like the gray -orange colour combo, but it starts feeling littlebit boring for few last days...

@nerdsforprez Thanks! It would be a honour for me. ;)

Thank you very much!
