    I see.....now it sounds even more interesting. And I also have a suggestion: it would be nice if this contest would be held in the summer, because more people will have free-time (including me).

    It sounds interesting, but I didn`t quite understand: we would have 24 hours to come up with a design or to actually build something?
  3. Lixander
    Ok, I understand. Also, thanks for the detailed answers ;)

    The other thing I wanted to ask :)) I had some problems with 2x buggy motors (MouldKing ones) not moving a heavier trophy-truck and when I contacted the seller, one of his first concerns was not to have 2x motors connected with one axle, the reason being that it might damage the motors by doing so. Now I am wondering: connecting the outputs of 2x buggy motors with one axle damages the motor too or just breaks or deforms the axles, frames and differentials?

    Quick update: the REVii front-frame and body-work are already built in real-life. The body-work didn`t had any design errors, but the front-frame..........I worked at the steering on the front-frame for at least 1 hour straight and made also some small structural changes. Anyway, if you didn`t understand from the last renders how the steering works, here it is a better explanation: the servo is connected to only one wheel hub trough a kind of a lever mechanism; then, both wheels are connected trough a ”steering rack”, for making the other wheel-hub to steer too, but the ”steering rack” are just some lfitarms that keep the same distance between the hubs (instead of the 7L or the 13L toothed liftarms made for that). This enables to make the model more compact, as it doesn`t need any space for the axle and gears of the servo. And, as a bonus, it takes away the need to center the steering rack and the centering problem that might occur. Also, I modified just a little the CV joints in the front. Now, the linkages seem to hold, even if the model steers and takes a bigger bump at the same time at full speed.

    The only thing I can say....great work! Also, you used only the small cylinders for the suspension? And do you connected 2x BuWizz motors with one axle?
  7. Lixander
    4x BuWizz motors in this pretty small build it is something to behold. You have done great! Also, you can try to take out 2x motors and leave just the other 2x, assuming the model is light enough for running with 2x BuWizz motors and so you get rid of another BuWizz hub too. But anyway, it looks good and I think it is pure fun to take it for a run (until something melts :/).

    Looks much more promising in a real-life photo ;)) I hope everything will come out as it is supposed in order to finish the RC Deck.
  9. Lixander
    Sorry for not mentioning :/ ...............you have to modify a lot the XL to fit that drone motor, so you are not wrong ;))) Also, I referred to the position and gearing of the motor housing that Krzychups, Gyenevsi and you were debating And, as a kind of a side note - I thought some time ago to modify the buggy motor (cutting the area where the actual motor is and adding a RC motor with the help of some 3D parts; I would have used the ”usual” 540 or 550 brushed motors or their brushless brothers).
  10. Lixander
    Also, have you thought putting the motor housing in the center of the model rather on its rear axle? Something like this

    Interesting. I tested a little the ”old” project and the only problem I got was the steering - small space, Lego parts couldn`t manage the angle too well. So the connections to the front wheels will pop-out or just fall apart due to the loose connection. So I decided to put the new CV joints on both ends on the REVii. Also, speaking of the wheels - I will test the new truggy as the ”older” one, meaning that I will test it with the 1.55” tires fitted on the smaller 43.2 d x 26 mm rims too (the ones I showed in the pics of the Goober Reboot`s red trophy-truck), because they are about the same size of the ones in the renders (56 d x 34 mm rims with the 94.8 x 44 R mm balloon tires). And yup, it surely going to be fun to run in a park with one of these :)) (I got around 7km/h with the ”old” one and, as I said, it had problems with the front linkage to the wheels).

    So, i really like to my make my life harder.........the 4x4 truggy will be replaced by a new model, based on the ”old” 4x4 truggy but with a completely revamped chassis and body-work. So I already put the last updates I made for the original truggy on its Rebrickable page and also there I subtly announced the new 4x4 truggy REVii. And the old W.I.P. topic, with the 2 W.I.P. photos: Now, about the new REVii. It retains the 4x buggy motors, the 1x servo-motor and the overall wing and body-work shapes of the first truggy but uses the fast output of the motors, has independent suspension on all wheels, narrower wheel arms on rear and front, more compact structure and a unusual servo-motor position. The strange way to install the servo and to attach it to the wheels makes more space and mimics the steering mechanism of the ”real” RC models. All these come in a pretty new body-work and with the wing attached to the chassis as most of the RC truggies have the rear-wing, opposite to the original 4x4 truggy, which had it on the body-work. Moreover, a ”fun fact” is that, while with 20g (about 0.70 ounces) heavier, the REVii is cheaper with with 40€ (or around 40$), even if it adds full independent suspension and pin-holes for a light system. You can find the Studio file of the both models on the REVii`s Bricksafe page.

    Well, 3s Li-Po might burn the motors themselves in time, as the 11.1V is close to the maximum of 12V. Also, I didn`t managed to burn any PF connector, just one but because of a short-circuit from what I remember. In my case, the actual motors got fried and 2x of them had RC wires and connectors. Buuut all of the 3x buggy motors I burned had the thermistor removed. I tested a 4th one with the thermistor on and it wouldn`t work. Anyway, from what I have heard, the L motors can cope with a RC system and have similar performances with the buggy motors. And by the way.........nice set-up ;)
  14. Lixander
    Yup indeed. Also, that is why I want to switch directly to complete hobby-grade RC electronics, including the motors.
  15. Lixander
    I see. i asked because I burned 3x MouldKing buggy motors with a 2100mAh 30C 2S Li-Po, but I took out their thermistors. With the thermistors on, the motors wouldn`t run at all with that battery.
  16. Lixander
    Oke.
  17. Lixander
    How many cells does your battery have? 2S?
  18. Lixander
    Out of curiosity: what looked incorrect?
  19. Lixander
    Yup, sure.
  20. Lixander
    Because the newer and bigger wheel-hubs have more mounting possibilities. Also, I am glad to hear that everything looks solid enough.
  21. Lixander
    New renders with the updates and modifications I made a few days ago on the test-build model - new front frame with bigger wheel-hubs and 2x hard 9.5L shocks, added 2x 6L links for the motors frames with 2x hard 6.5L shocks and modified the front-end.
  22. Lixander
    Great job! I really like the detailed rigging and the small details. Also the stand looks really good. Keep up the good work!
  23. Lixander
    Yeah, probably.......I forgot to put 2x hubs at once, so the motors could draw more power. But also, in my city it has snowed and the snow started to melt.......so it is that "perfect mix" of snow and water that makes it extremely difficult to fully enjoy the Lego models outside.
  24. Lixander
    I just ended the 2nd test-drive some minutes ago for the BBX replica.......conclusions: 1.the model is good and 2. don't run servo's in the snow for too long :/ As you can see, I reached 9km/h with the replica with the MouldKing electronics.

    His Rebrickable account was blocked or deleted and because of the "situation" in the area, he can't use PayPal, so he can't use Rebrickable anyway. So he moved to Boosty - a russian platform similar to Patreon. Even if it is pretty uncomfortable to browse such a page without knowing the russian language, it is more advantageous because you pay around 5€ for all the instructions and some bonuses instead of paying 5€ on instructions for only one model.
