    the car was cogging, gearing was too high, which you already know, or you can stick a lower KV motor on it. but lower gearing is better as with 3d printed gears, you cant put a ton of torque force on them or youll be printing them every run

    An issue that I saw and is possibly the reason the rear tires got pulled off the wheel hubs is that there is no differential. The back wheels can't turn at different rates around a turn, so they scuff. It makes steering harder as well. It might be difficult to design a strong diff for 3d printing, so you might decide to use an off-the-shelf version and integrate it into the rest of the 3d printed car.

    I remember watching your first video, your 172nd subscriber lol. I'm happy to see you've grown past 1k and your videos are in my recommended! As a mechanical design engineer I can tell you put a lot of effort into this build and the video, great edits to the point but also showing your shortcomings in the process. There will always be hiccups and compromises, such is engineering! This may be a RC car but the design process is no different, take a lot of trial and error and patience to get it right! Awesome going man, looking forward to more!

At least we have something that allows us to be creative, resourceful, come up with things and then see them materialize... work on our own or on a team, to lead that team, to work with every single other department in the company... this is all great stuff!

    Cool! Like the details like the ackerman steering and camber etc... Im similarly working on a 1:4 scale rc F1 car also mostly 3d printed with an aluminium tube chassis for easy "modulation" of all the parts, im also using onshape but some things I learned from researching F1 physics are that regular ackerman steering is infact the OPPOSITE of what you want, anti-ackerman steering is when the outside tire turn more than the inside tire as there is more load (=more grip) on that tire when the wheight of the car is shifted over that tire, and because of the increase in grip it can turn sharper without loosing grip or "locking up". Maybe worth trying, I have also ran into the issue of too high motor rpm, my solution was a planetary gearbox with the motor inside the actual tire which eliminates flimsy 3d printed shafts and couplers. Additionally only having a slight front wheel camber and about a 10 degree caster angle (for the front wheels) should make the car better in addition to about a degree of toe again only on the front tires.

    This is fantastic, I love to see it. As an engineer, and an RC enthusiast, I have some input for you that may help the dynamics of the vehicle. if you move the front and rear shock mounting point up about a half an inch, and get longer shocks with softer springs to allow the control arms to parallel to the ground you will get better handling characteristics.
    Having Ackerman steering is fantastic, I don’t know if that was your intention originally; however, that is exactly what you want. Do you want to shoot for a roughly 2.8 to 1 or 3.0 to 1 gear ratio for the transmission.
    Let me know if you want any help, or need someone to bounce ideas off of! Keep up the great work!

    • @filippus_
      @filippus_ 5 місяців тому +1

      It would be cool if someone tried anti-ackerman or reverse ackerman steering where the outside tire turns more than the inside one because as the car turns the weight is shifted over that tire giving it more grip which allows it to turn sharper than the inside wheel without loosing grip and sliding. Im trying that concept out on my 1:5 scale 3dp F1 car. We will see if it works! Also, for a small brushless 3900kv motor you probably want to opt for an even lower gearing as just with a 2s lipo it will be spinning almost 30k rpm which would in theory make it go 1000km/h directly connected. A 1:10 gear ratio is probably more suitable

  • @licencetoswill
    @licencetoswill 5 місяців тому +10

    Stick with it, you're definitely learning as you go. Dont forget to offset your universal joints by 90degrees on the rear axles, they should not be in-line like they are now.
    I'm curious why the upper suspension mounts are on cantilever arms like that, it's very prone to shear failure. mount them directly to the chassis above and beef them up. Your rear lower wishbones have susbstantial twisting loads from the new location of the springs, but the top mount will fail first. bring on the next vid!!

    Great project! I have done a few 3d printed mods to my rc car, and one of them is a 3d printed gear reduction, a fix I found to avoid the gear getting chewed by the motor shaft is to have an actual metal gear to fit inside a 3d printed gear, like a threaded insert, this way you know it will stay in place and not get obliterated, if you need i can send you some picture and cad files. Keep it up!

  • @tinkerman-q

    Wonder if you considered printing gears and other parts susceptible to heat creep in PA-CF filament. It can sustain an insane amount of heat (easily up to 150 C, without any performance loss or deformation), and it is almost as hard as aluminum.
    It is a lot easier to print than plain PA (Nylon) and the finish looks great.
    It is not cheap, but the amount of printing it can save and time from having to adapt design, easily makes up for the extra 40 bucks a kilo.
    Also quite lightweight too.

    The slow speed chattering is called "cogging" and is because your using a sensor less motor and ESC, the ESC can't tell where the motor is in its rotation.

      Cogging is a torque fluctuation due to the saliency of the motor. The chattering is given by the loss of synchronicity caused by a too high starting torque.

    Another thing, you can try a brushed motor to avoid the cogging. In this kind of set up a I think that a brushed option is the best. You can check a sensored brushlees motor too, but is more expensive of course. Please, all my suggestions are with the greatest of respect. This is a beautiful project.

    Gearing is tough, but I’d look at what cars the motor and esc are intended for, find out the gearing of those, and try to replicate it. I’ve seen those cans before, but forgot who makes them. I noticed it was a 3000kv, and I run a similar motor (3800kv) in my Arrma Granite Voltage, which has a final drive ratio of 15.11:1. It might be a bit expenive, but I’d try to get PCBway to CNC some metal gears once you decide on a ratio.

    Are you using matte PLA or ABS? Matte PLA is slightly weaker than normal PLA and has the same issues (melting in a vaguely warm car). PLA and ABS are more brittle and less impact resistant than PETG so I'd recommend PETG next time you have to reprint a part. PETG looks ugly, is annoying to remove supports, and can barely bridge, but otherwise it's a bit tougher.
    If you use PETG, find a tutorial for your exact printer, AND print a temperature tower with 1° at a time in case your manufacturer is a different temp. The exact ° when your temp tower layers can't be peeled apart by hand is what I go with (257°C in my Ender 3). A smooth G10 (aka FR4) bed is cheap and required in my mind because it makes any plastic pop off the bed. Never print PETG on glass.
