  1. Some things I noticed: Next to the red bevel gear, there looks to be a 1 stage planetary gearbox half what is found in the existing motors, the bevel gears (and existing norms) mean side outputs but there are odd structures that could be a rear pass-through that would be better for awd mocs (though it could just be for LEDs 7 and 8) At the other end of the drive motors, there is a piece on the spindle that locks to be for encoding Internally the steering motor assembly looks to be somewhat separate so expect a tank-specific hub without steering in the future Not sure why but the bevel gears are off-axis compared to the motors so perhaps not planetary reduction? Not what I had hoped for but better than nothing, I had lots of fun when I was younger with the power functions era version of this (until the battery pannel clips broke)
  2. Have finally improved my engine and the design now peaks at over 2800 rpm (almost 50 revolutions per second) and best of all it is a ridiculous mechanism, no simple slide valves and has 3 cylinders. For the video on it I want to make a sort of speed run history sort of video, where I go through the process of how I got to this engine. But I want to try to make sure that 2800 rpm is the highest currently obtained, has anyone seen an engine that revs higher, I have tried to keep a look out but mostly find videos vastly overclaiming rpm i.e. 8000rpm where the design is good for 1200rpm Excluding turbines, they can rev to over 10K rpm I know this is a fringe interest so sorry for asking such a specific question
  3. If Lego produce significantly mor powerful RC they would most lightly shift to self-contained gearboxes and differentials, while Lego can be made somewhat dangerous now significantly more powerful motors would make exposed gears untenable both for safety and longevity (from Legos perspective at least). My guess (if it has good power) would be a combined motor and bevel box (and hubs) with proprietary outputs so they cannot; without non Lego parts, be connected to current technic drivelines. Probably just 0.x increase in voltage though.
  4. I used 4 small cylinders with water for a l gauge "steam" train, 2 pushing the rods and 2 driven by a motor I hoped it would move realistically but was jittery even after removing all the air I think the problem was the rubber hoses, would like give it another go but I am out of cylinders
  5. Surprised the suspension is not realistic, the whole build seems week too the whole front end flexes with steering (bad mechanical limits). The whole hybrid system is a simple motor charged operation idk why. I guess its all on Legos next supercar flagship now (fingers crossed for realistic duel clutch now they have the elements)
  6. Seeing it in detail is genuinely making me sad, what could have been... I does look very unfinished and the design of the weights seems intentionally limiting (hard to integrate in something that spins) my hope for the new supercar is markedly lower now
  7. The new hubs are weaker in some situations than the old ones as they do not allow for an axle passthrough. The shorter axle has been in my MOCs for years lol. The problem of braking parts has been reduced lots but still is a problem for fast rc, but the plastic melting is becoming a limiting factor now even with grease. I hope Lego adds elements featuring bearings in the next few years...
  8. Been waiting for a system like this since duplo cant wait to see it in action. Just found the your YouTube, is this representative of the final product or still prototype. The motor seams comparable to a buggy motor on buwizz.
  9. You really need two cylinders in series if you using pneumatics, pneumatics work with force unlike hydraulic which work with distance so the pressure would have to be constantly varying on both sides for stable steering without about 100 times a second adjustment it jitters all over the place and uses a ton of air. With two cylinders you can get a stable left right and centre for most mocs, if you can put up with 3 steering positions I managed to get a single cylinder system to work with a mechanical system that linked the steering servo and steering position driving the pneumatic switch, it worked well with a variable backlash but required an unrealistically large volume of air to work. I also tried linking two cylinders hydraulicly and driving one to drive the other but even a slight leak ruined the whole mechanism. There is a third party hydraulic pump you can get and is the best solution if a bit expensive
  10. Almost identical MOC if you want to see the functions in action LEGO Technic PERSEVERANCE Mars 2020 Rover + INGENUITY Helicopter - YouTube
  11. great scale love the choice of steering over drive, a case where a lack of realistic function is a good thing gears and shafts over servos. This set would be 10/10 if good price the wheel mounts don't flex too much and the tires are rubber, but I suspect the tires will be plastic due to there limited potential use + realism. If you where willing to bend the visuals It would not be too hard to give the wheels drive via shafts, but motorisation would lightly be too heavy for the structure as it is now
  12. When I first saw it I though you had linked pics for a star trek moc by mistake, looks great like a cross between a bird of prey and an sr 71, all models should first be built in harlequin first i think there is some law. Hope it is successful
  13. thanks they do sound a lot more impressive than then numbers suggest, super disappointed I could not get to 3k though even with a pre EU ban vacuum cleaner
  14. can u link a video? they do sound like they run far faster than they do its a real disappointment when you measure it to me at least Sry did not mean to sound disparaging of other peoples mocs people have built ones far more impressive than mine just mine is optimised for rpm
  15. Sorry should have clarified it comes in waves with the buwizz app dont have controller with me to test with brick controller. Can still make a video if you are curious though
  16. Does buwizz 3.0 use current control or voltage control when used with brick controller? Rigged up 2 buwizz 3.0s in parallel and it works but the power comes in waves, I assume due to the output being current controlled
  17. I'm back baby Tried to get every angle but sure I missed some. Sry no pics of the baker valve gear it hit hard when I realized it would be to large so it got tossed asunder in favour of this. Wheels are custom but somewhere between xl and xxl i think - no binding on curves at all The limiter is not quite limiting enough so reverse is no so smooth easy fix but eFfOrT The 9f is done but digital only - the mechanism is one I purposed to get the 9f to beat the t1 (and mallard) if the yanks manage it; but seeing I lack 10 million pounds a model will have to do. How and why the 9f you ask find out in 6-8 months when I finally get around to ordering the many parts (60ish cm long) The running little 1/360 stud train set in a carriage is finished as has been for months but have been waiting as its probably my best Moc, people how have seen it think so at least (especially considering it has no modified pieces) Forgive the odd driven (not here) tender it's just for a basic train that can pull the small train carriage with no traction tires as the set is driven by the bogies.
  18. Thanks it was a pain with my 3d printer as the holes need to be smaller than Lego standard to reduce play enough for the middle cylinder to move the same-ish distance as the outer 2
  19. Finally got around to filming. This thing is absurd it gives some hobby grade Rc crawlers a bad name. 20221017_203011 by michael waterfield, on Flickr Minifigure is not quite to scale lol, you can also see the airlines for the locker 20221017_202949 by michael waterfield, on Flickr Body proportions aren't great but not terrible either not helped by the lack of conventional suspension and the hideous compressor 20221017_202755 by michael waterfield, on Flickr Here you can really get a sense of how much is going on, including the gears in the planetary hubs there are 86 gears in just the drive train. Traxxas tires use a strange bead, I assume for drm, which made it hard to make rims for. My solution is not perfect but works for the slow speed. The rims neck down internally to ride the jockey wheels on the hubs, this acts like a wheel Bearing and allows for these huge tires without them wobbling all over the place. Traxxas summit tires are some of the largest rock crawling Rc tires you can get but this might change as more people get into 1/6 crawlers (this truck is 1/12 and still bigger than some 1/6 trucks) If I use it more I will need to add some more metal bushings to the axle drop boxes, as I have already had one instance of pieces melting then fusing together. This still uses my home brew motors which have proven themselves to be reliable with only one failure on my direct drive buggy which has since gained a Cush drive to prevent it from happening again. The Cv joints are holding up well with only surface level erosion but I do keep them well lubricated. Hopefully I won't have to machine metal ones. Spinning all four wheels on tarmac is crazy for tires this big and gummy. Idk what else to say, enjoy the video (walkthrough and action shots) Pity I don't have a zeroes to compare it to though
  20. I just wanted to show you my truck, and he suggested I should leave the forum because I did a video instead of text. Thats what I was referring too, I called it the biggest because I believed it to be an accurate description no other reason - I don't get money from YouTube I post because when I was younger I watched zerobricks for hours and wanted to be just like him; when he comments it means the world to me. I thought I was happy here commenting and posting, but you actually made me cry I don't care if its poor English or what but you two really hurt me I just wanted people to have the same fun I used to get from watching zerobricks. I think I will stick to YouTube now just like you said.
  21. Some people prefer videos but will add text. You know of a bigger one cool; can you link a source? - Look I'm here for fun, Lego and nothing else can we stop with the non-Lego discourse it is against rules after all. That truck is narrower has smaller tires and is yet tube motorized, still cool though
  22. But the video has all the information + pics you could want; text seemed unnecessary.
  23. A teaser, will probably be a week before I can borrow a good camera to film with and yes that is a Unimog tire lol. 20220912_231818[1] by michael waterfield, on Flickr
  24. Will make sure to show all in the video - my old truck uses the same wheel connection, no turntables, a capped axle with a threaded nut holds on the wheel and idler wheels against the rim (try to) keep the wheels straight.
  25. Finally I have made my first video, hopefully the first of many. I explain a good deal in the video but I left some things out like how many pieces are modified - can you spot all of them. I know you cant wait to see the plane and tank in action, I cant wait to answer your questions. The old buggy is the only official set I have together.
