    Oke. Sure: I was saying that instead of the 12t Lego gear and the contraption with the plastic card, you can use a 12t mod 1 pinion gear from a hobby-shop near you. It might be hard to find such a pinion gear with a 3.17mm motor shaft hole, but you can easily get a shaft adaptor. I use one of these pinion with 5mm shaft hole, but I got a 5mm to 3.17mm shaft adapter.

    Very interesting. I was also working on a brushless mode on the same trophy truck, but I stopped due to the fact that I used the new CV joints, which I found by myself that simply can`t take the speed and torque of a brushless set-up :/ Moreover, nice to see someone who managed to get such a high gear ratio using Lego gears without having tens of gear sets. Also, what motor size do you use? I wanted to fit a 3300KV 3650 sized motor. P.S. - an advice: the 1 mod 12t RC pinion fits the Lego gears perfectly.

    Soo....I wanted to start testing the Lego Neo Fighter this week, but I soon remembered that the space left for the hubs was not sufficient :/ Moreover, the 1st replica had some traits of the original, but it was not so ”loyal” to the characteristics of the original. So I started from scratch with a new replica that has a chassis that ”respects” more the proportions of the Tamiya buggy and a bodywork and wing that are detachable and that also look more like the ones in the real buggy. Also, the 4x4 driveline was dropped, as the original has rear-drive, for the suspension frames I used the angled 4-6 9L lfitarms and I found a solution for one of the most annoying thing (when you try to replicate an RC buggy with Lego), which are the tires. What do you think of the new replica (the model that has blue accents)?

    The 4x4 version of the Beach buggy is live on Rebrickable - https://rebrickable.com/mocs/MOC-202282/Lixander A./beach-buggy-4x4/#details

    I see..........welp, then the issues are only for my hubs then :/ And I think the CaDa`s clear connectors is not compatible with the Power Up / Control+ ports Also, everything works ok when you stack 2x buggy motors on 1x port on the white JV1010 hub with PF ports?

    I also spoke to CaDa after I made a video with the 4x4 Beach buggy (900g / 32 oz with 2x hubs, 2x buggy motors and 1x PF servo at around 7°C / 45°F, but it behaved the same in the middle of the summer at around 30°C / 86°F with a different model). Here is the video........it is exactly as long as the fully charged hub lasted https://drive.google.com/file/d/16dgBHmdi29Ys46QdPlTKWfytDeRBmotN/view?usp=drive_link Also, here are their replies.......the last one tops them all.

    Just tested indoors a little the 4x4 Beach buggy and I can say that it runs decent enough. Maybe with a BuWizz set-up, it will have more performance. Anyway, some rectifications were needed in some spots, especially on the suspension, as the 1st set-up was too rigid, but I should manage to finish it in 1-2 weeks.

    I assembled the complete hub unit of this set with the help of Philo`s unofficial files from LDraw.org - https://library.ldraw.org/parts/41282 In order to use it, you 1st have to download the .zip file for the whole unit (1st section) and make the connection points in the Studio Part Designer. Then, you can use this: https://bricksafe.com/pages/Lixander_A./miscellaneous/porsche-gt4-e-performance-hub Also, sorry for posting on this pretty inactive topic.

    New W.I.P..........the 4x4 Beach buggy is in the works. The 2nd 4x4 prototype uses 2x buggy motors, the new yellow differentials and the new CV joints paired with the Audi e-tron wheel-hubs at a weight of around 900g / 32oz with 2x BuWizz hubs. The rear frame is completely new, while the front is heavily modified in order to install the taller wheel-hubs. Moreover, the connection of the front with the main chassis is also overhauled and the 6.5L shocks and the small pneumatic cylinders were swapped with a total of 4x hard 9.5L shocks. I should start test-building the Beach buggy 4x4 pretty soon ;)

    Sorry for derailing from the last posts in here, but does anybody experiences issues with the performance of the ”new” and ”specially made for buggy motors” CaDa JV1010 hubs (the ones in white and with PF ports)? I was curious, as mine are pretty crappy and on the official website the PF version is nowhere to be found. Soo, my hubs charge in over 2 hours and one of them in 10 minutes from 0%, have short playtime with full battery (around a maximum of 5 minutes and for the one that ”completely” charges in 10 minutes is depleted in under 3 minutes) and I can not stack 2x buggy motors on 1x port as the 1st stacked motor will barely run and the other will stall (on the much cheaper MouldKing hubs I could stack them with no problems; that is how I reached 16km/h without having twisted fingers due to the numerous buttons I have to control at once, as with the CaDa hubs and remotes). Moreover, even with 1x buggy motor / 1 port, the power seems to be pretty low, as my models barely could run, even with a ratio for torque (1kg, 1:1 gear ratio, 3x hubs, 4x buggy motors and 1x PF servo..........the model barely worked; 1.5 kg, around 1.60 gear ratio, 2 hubs, 2x buggy motors and the PF servo...........the model made a few meters, as I just couldn`t watch how slow it was; 900g, 3:1/ 2.34/ 1:1.4, 1 hub, 2x motors and 1x PF servo...........the model was slow and had some torque but it felt like the hubs didn`t had power/ same, but a bit faster/ the model barely moves).

    Hey! Thanks a lot! Not at all. But I still don`t have a BuWizz and I use CaDa (the new white JV1010) hubs now, which are pretty bad: long charging time, short play time and small current or something like that I think, because I can`t stack 2x motors on a port as one motor will barely work and the other just stalls. But anyway, I am closer than ever to actually start the project RIOT, just have to gather some bucks :/ Also, i tried other 2x models with the brushless set-up since the Retro sprite buggy MOD, but both of them had problems with the drivetrain, due to the CV joints or to the slipping gears. https://rebrickable.com/users/Lixander A./workbench/14713/

    I am working on a RC mod of this Dune buggy made by Offroadcreations: https://rebrickable.com/mocs/MOC-9871/offroadcreations/blueprint-dune-buggy/#details I already built it but, as I expected, the model is a little too fragile due to the relatively complex shapes and simple connections. So, I modified several areas in order to motorize it and to make it more sturdy, but I am still not sure that it is enough..........so this might be scrapped in the end :/ P.S.: This model was scrapped, but you can find the Studio file in here - https://bricksafe.com/pages/Lixander_A./lixander-mod-dune-buggy/wip

    Thanks for the addition ;)

    Usually, the motors come in a pack with an ESC (Electronic Speed Controller), but it is also needed a receiver/ transmitter (remote pack). For power, usually LiPo batteries are used, but there are also other technologies. Moreover it depends on the needs of the motor setup to determine the battery cell count (and thus the voltage), but one cell (noted 1s) should have at least 3.7V when discharged and 4.2V when fully charged. Lastly, there is usually no need to program anything, but there are some motor setups that can have several settings and come with a ”programing card”, but you just select some values/ setting there, so yeah...........no programming needed.

    Welp, if you remember the Retro style buggy from around the spring of this year..........I rebuild it, as now I have the clutch gears it needed and it turned out that in fact it was a building error not a design one :/ Anyway, I made a 3rd revision and also did a version with a PU L motor. Also, if you don`t remember the specs, here there are: a rear-wheel driveline through 2x buggy motors, 1x PF servo/ PU L motor for the steering an independent suspension on all arms, with 4x hard 6.5L shocks in front and other 4x hard 6.5L shocks at rear a detachable wing and bodywork Moreover, here are the new things on the REViii of the Retro style buggy: longer chassis than the first variants that can hold the BuWizz hubs inside the center of the bodywork and that adds more stability 2x gear ratios available - 3:1 ratio (found in the Studio files) and a faster 2.34:1 ratio 2x versions: 1x BuWizz 2.0 with 1x PF servo or 1x BuWizz 3.0 with 1x PU L motor Of course, the model is already on Rebrickable ;))

    You did a great job! I hope we will see more of these mods from you ;)
  17. Lixander
    I see.......thanks! Much more speedy indeed.
  18. Lixander
    I see.......I thought it was due to the BuWizz also :) Out of curiosity.........what gearing it had before?
  19. Lixander
    Really nice! Those PF XL look pretty fast in the video, but nevertheless, the crawling capacity is great. Keep it up! ;)

    The Tortoise buggy is on Rebrickable - https://rebrickable.com/mocs/MOC-200037/Lixander A./tortoise-buggy/#details
  21. Lixander
    While the 1st version was also good with all it`s features, this one matches the level of the mechanical features with the looks. Excellent job!, keep it up ;)

    The planned drive-line for the 4x motors version of the Ruslan.
  23. Lixander
    Well, @Aurorasaurus, I eventually put another 2x buggy motors and an additional CaDa hub, but the gearing had to be modified so now the ratio is around 1.19:1 (28-16, 16-20, 14-22) with the differential. But the gears are making some noise, I don`t know why, maybe because one of the gears is damaged or some gears are not aligned properly due to the structure...........in plus, I discovered from the 1st day since I received the CaDa JV1010 new (white) version hubs that the remotes are not very friendly at all when using 3x hubs (I put them as in my older MouldKing hub remotes - photo bellow, so they should be somewhat comfortable to control in theory, in practice not so much:/) and the hubs seem to be pretty ”lazy” when speaking about the buggy motors, even if the hubs are described as ”made for the buggy motors”. That applies for basically any buggy motor you put, no matter the number, be it 1x or 2x on one hub. The MouldKing hubs are a little cheaper (not only at price but at quality also I think) indeed, but for my experience so far with the CaDa ones, the MK ones have more punch, especially considering that on the MK ones I could stack 2x buggy motors on a port when for the CaDa ones, for 2x ports and 2x buggy motors the perfomance is somehow decent, but when stacking 2x motors on 1x port on CaDa hubs the 1st motor runs very slowly and the one on top simply doesn`t work. I will continue to fiddle with the gears anyway and I will also see how I will get around with the hubs.

    Thanks! No, the small soft shocks are not connected between them by an antiroll bar. They need to support the rear axle from behind and keep the 2x bottom-rear suspension arms independent. That is what I am feeling too at around 1kg and 400g with the hubs (the model weights 1kg and about 200g without the hubs, so with 2x hubs, it should be around there), but more motors would be hard to install and the supplementary hub needed for putting 4x buggy motors definitely wouldn`t fit. So with only 2x buggy motors and 2x hubs (the motors were only on one hub and the servo on the other hub), the model had an average speed and some torque (I think); it was getting more speedy when running in straight for some time. But after I got in touch with Zerobricks (he was in Romania for the annual Technic contest held by the Romanian LUG), he advised me to left 1x motor on a hub and on the other hub to put the other motor and the servo. The model seemed to be more powerful, but the batteries got low and I couldn`t continue testing it properly. Tomorrow I will record the speed of the model (with the port setup recommended by Zerobricks) and I will also try to make a video.
