    Thanks again ;)

    And how it ended for the car? Oke. For me, it always does that up until 2/4-3/4 of the throttle.

    The instructions said that 2 wires should be reversed if the motor spins in the wrong direction, but I wasn`t 100% sure despite that. But I just remembered that when I was testing the model outside and decided that, even if something happens, I am in an open space. Also, thanks a lot for the resources! But I still got a problem though: the motor cuts the RPM at low-medium throttle and I tried all the settings on the programming card and nothing. Moreover, on the internet there are few cases and informations about such cases, most of them remaining unsolved :/ Maybe if I change the throttle dead-band the problem would be solved? (this setting must be done manual as it isn`t on the programming card)

    Thanks!

    Thanks! I still have to get some extension cables for controlling the RC Deck maybe even a new smaller battery. So I didn`t do any test run, not even an indoor one :/

    As I already mentioned in my topic, I am making a vintage buggy for the TC27 with 1x PF L motor, 1x Geekservo and custom control unit with separated LiPo battery and receiver. If these electronics don`t respect the rules I kindly ask the moderators to delete this topic. Also, I know that the tires I used are not fit for the contest. For the final photos I will get and put the right tires. Moving to the build, I had problems with the front shocks tower, as the shocks were too big and put the suspension arms under tension. So I had to make the tower wider. Apart from that, everything went smooth to finish the model in around 2 hours; I would have been faster if I would have stored the parts in a more organized manner :/ Buut, after I almost finished the bodywork I started to think where to put all the other electronics..........the RC Deck barely fits and the receiver is pretty small so I can squeeze it somewhere too but the battery has no space, at least the 2200mAh I got. So I think I will need to get a new smaller LiPo :( Not to forget about the suspension.......the front has a crazy amount of suspension travel and the rear, while has much less travel, has enough though.

    Thanks a lot! ;)

    I always wanted to use the small 30 mm wheels combo in a buggy - ”combo” because there is also a thinner rim version. And finally, I made one which can also fit the topic of the TC27 (if I use the same wheels in front). I have some other tests for the TC27 but this one is just the best. Moreover, the bodywork is pretty simple and it is inspired by the vintage baja buggies, hence the name (see the spoilers). It uses 1x PF L motor and 1x Geekservo (because the Lego servo is too long) as electronics and 2x hard 6.5L shocks for the front independent suspension and another 2x hard shocks with the same size for the rear solid-axle suspension type. Most likely, I will use a hobby-grade LiPo and receiver/transmitter pack paired with @NoEXIST`s RC Deck for making the model fully functional.

    The Studio file of the RC-E buggy - V. LEGO is now on Rebrickable

    Here is the first ”proper” off-road test run of the brushless ”Sprite retro buggy”. As you can see, with such power, fitted with the Lego 81.5mm Audi tires and with my level of skill, the model went drifting uncontrollably very easily.

    That gear ratio is more than enough and the motor - ESC combo most likely is ok so all that is left is the controller.....so yes, try to play a little with the throttle trim :) Also, you can try to inverse 2 wires on the motor, if the instructions manual states that you can do so in case of some problems. My SkyRC combo (3650 330kV motor with 60A ESC) is still stuttering at low-medium throttle, but I had discovered that the motor was inversed when the wires were color matched. So when I switched 2 wires, the motor started to run at its full power.
  12. Lixander
    What motor do you use? And also, what is the final gear ratio?

    My Lego tier on my Patreon page is live. It has the Studio files of 5x W.I.P.s. Among them is a new model that I made in Studio in the last 2 weeks, the updated RC mod of the ”Sprite retro buggy” made by Apachaihapachai and the 1st off-road test run of the brushless modified Sprite buggy. The video of the test run is set to be made public tomorrow on YouTube.

    @Fluwoeb the paint job looks excellent! Also, it is really interesting the damage you got on the new CV joints. But I think the angle you mentioned in the middle of the post explains it all. And @Aurorasaurus great little car.......you can say it looks like the Gemballa Marsien.
  15. Lixander
    Well, I am not among the first ones for sure :)))

    Thanks! In my case, the whole RC set-up costed me around 200€/$, but in my country that means 1000 bucks. Anyway, most of the electronics are from AliExpress, but they are quite great for the price (motor + ESC + programming card around 60€/$, receiver + transmitter about 20€/$, Li-Po battery + buzzer under 25€/$ and battery charger about 60€/$). Moreover, the 3D printed motor adapter holds pretty great for just under 15€/$. And recently I started to use a metal pinion (under 10€/$). Also the Lego parts hold fairly good, but I observed that some axles and gears start to deform or "bite" into other parts due to the high RPMs or due to the heat.
  17. Lixander
    Interesting!
  18. Lixander
    No problem! Looks pretty good with these rims too.

    The only place I could find that wheel is the LDraw library - https://library.ldraw.org/tracker/25165, but most of the new parts you can also find on Philo`s page - https://www.philohome.com/studio/packs.htm Philo`s files already have the connections data, while the ones on LDraw rarely do. So you might need the Studio PartDesigner in order to add the connection points (it is not that hard by the way........you just open the .dat file and align the connection; you need some patience though). I also recommend to check how to correctly put custom parts in Studio, as I forgot how to and I can`t give any advice on that part :/
  20. Lixander
    Then there are some 8T pinions for sale out there, but, for the other things, I don`t know what to say :/
  21. Lixander
    There might exist, but even so, there should be rare. Also, Module 1 pinion gears (these mesh perfectly with Lego gears) with 8T are pretty much nonexistent.
  22. Lixander
    I see. Thanks for the reminder ;)
  23. Lixander
    Yup :/ 51 km/h........that's more than a decent speed for a Lego chassis. Bravo! Do you use ball-bearings in the wheel-hubs?

    @Ryokeen I forgot to mention this.........in addition to the RPM cuts, the motor seemed to be more fast going backwards than frontwards. So I decided to try and see what happens if I swap 2 wires, as the instructions booklet suggests in case that the motor is reversed (I was afraid to do that earlier because I thought that I might create a short-circuit or something like that *R.I.P. my first Geekservo.......sobbing*; anyway, I switched the yellow and the blue wires between them, just to be ”safe”). And guess what.........the ESC went into the calibration mode and after that, success!.......the motor showed it`s real power. And so I had to set the Punch control setting to almost 100% so that I wouldn`t lose a 3rd 24t gear (which is the gear that meshes with the metal pinion; the 2 gears that went to garbage weren`t shredded..........there were simply cut, as you can see in the 2nd image). Though I forgot to check if the motor still cuts its RPM at low-medium throttle, but at least the motor feels more ”natural” now and together with the ESC it is calibrated properly. Also, those 24 km/h / 15 mph were achieved on a pretty small (and fairly crowded) street in my city (see the 3rd photo), so the model should reach at least 30 km/h / 18 mph within bigger spaces (and in cooler seasons - in here it was over 30 °C / 80 °F).

    Oke.....more freedom in this way :)
