About the 3d printed part: The top of the part has a slight slope which had to be supported. Also, I printed it at 0.28mm layer height which made the surface even worse (I tried it) I didn't any method to fill it, so I printed it again.
Even with the slight slope, you could have orientated it so that the slope is flat against the floor some slicer have automatic detection of flat surface and arrange the part perfectly flat. The wall of the enclosure instead of being printed straight up, they would have this small slope but a printer can print at least 45 degree without support so it wouldn't have mattered!
I am one of your subsribers and love his and your videos. That is what I call PROFESSIONAL LOL your professional videos Kev are Halarious!!!! Keep up the good work Kev even tho we are on JohnnyQ90's channel:)
Omg this channel is like a medicine for quarantine depression Okay so it's a good time for an edit I guess, besides all the fancy comments and jokes, I wish all the people who are infected to get well and this pandemic will be over so soon. For the people who lost their lives, we cannot feel sorry enough for them, may they rest in peace. And for all health care workers out there, we cannot thank you enough, our prayers are with you...
It’s great to see there are people like me in this world that know how to build things and build things right. I’ve been a machinist since 10 years old hanging around my dad’s machine shop watching my dad he was a master machinist. I built some of the greatest pool cues for the last 20 years built all my own jigs . I have a machine shop with over nine lathes , Mills all old school from the 40s 50s and 60s that I have completely rebuild myself mint . I’m in my late 40’s and retired now for the most part . Watching your vids takes away anxiety and is very soothing. We need to team up and build some shit...I built three CNC machines from scratch and they were better than anything sold for Cues vary highend like the stuff your doing . I built my own spindles u name it .. your good though ... vary good ... love the vids ..
It's never too late to learn, the issue for me is money. If I had the money I would definitely buy a CNC, lathe, 3d printer and stuff but that is a pretty penny for those machines plus the training involved. I have those machines at work in my maintenance department but I have no time to learn how to use them. It always comes down to money. This is amazing work and I dream one day I can have access to stuff like this. I love building rc cars but this takes it to a whole other level.
When you are at this point of production and "scale parts", I want to add some constructive critics. There is only one thing. And that is the radial holes you make on the discs. On real cars the holes from the radial holes, match up with the axial hole pattern. Since you use such large drill for the radial drilling. You could just offset from tangent and actually hit all three holes you drill axial. To do off tangent drilling, first use a normal endmill to make the pilot surface and hole, and then drill the holes as normal. Awesome work. You take your 5th to new levels every time. Keep it up!
@@bruhlol9694 He's saying the holes drilled into the face of the rotor do not align with the holes drilled into the sides of the rotor, as you would see on a more "conventional" drilled and vented brake rotor.
Most radios now have a pulsing function for the brakes built in. If you just activate it on that channel for the servo it should work. (its a non feedback system, so it basically just pulses the brakes.) A real abs system would be crazy though.
That would require at least 4 rotationnal speed sensor (one for each wheel), and a microcontroller that receive the brake signal, and command the brakes by mixing the informations given by the sensors and the order given by the transmitter/receiver... Maybe on bigger cars, but here we are running out of space 😖
Absolutely Brilliant, I know every one of us that RC'd wanted this stuff. Unfortunately for us we lived in the 80's and had nothing close to this. Kids today should be so thankfull that all this is avaliable today. I remember when the wire edm started and thought that was cool, then water jets,milling machines that are computerized, awesome.what I would have done to my Kyosha ZR-1 Corvette.
Bro.. Could've printed the cover upside down. Still turned out nice though. Try using tree supports if you're using cura. Tree supports pop off super easy and reduce print time!
hi johnny, i'm accompanying you here from brazil and i have to say i'm addicted to your videos, i've seen them all and i can't get enough of repeating until a new one comes out! never stop with the detail you have in your videos.
As a big RC junkie myself I would love to have these tools and machines. But somehow I don't think I will be able to convince my wife that I need $100K in tools and equipment to modify $500 RC cars and boats. LOL
@@kleetus92 any other person I'd wager they'd do cable. But knowing Johnny he will make a full automotive braking system. Booster, lines, ABS, the whole 9.
@@LeglessWonder those are mechanical calipers not hydraulic piston type to use hydraulics to power them is almost ridiculous however hydraulic is always better
Cody Evans From what I saw in the vid, the brake calipers do not look like they are set up for a hydraulic system. Although, if Johnny somehow manages to figure out an automotive grade system you describe, this car would be on a whole other level.
@Petey Barnum 3.2 hp isn't a ton of power considering that some race nitro engines can reach about 3 hp with 3,5 ccm. Sure they have way less torque but about 4 times the rpm and they weight maybe a 1/5 ? And as you know... its the ratio between weight and power that matters
Glass transition: 70°C on PLA, 80°C on PETG & 105°C on ABS I've put a PETG print in my car (in the Florida summer sun - 38°C out side) and it was fine.
This is the coolest thing to me, ive recently been watching videos of these real mini engines and different builds. I'd love to have an rc car build completely operational like this just for show.
wow, that is so much plastic waste try print it upside down, with mostly rounded edges like those, you can eliminate all the support with most printers
@Ck CHEUNG I figured the same but after further thinking I realised that since the edged of the print were round the printer would've had some trouble printing them since the overhangs would've been so steep!
@Ck CHEUNG The top surface has a slight slope which had to be supported. Combined with a layer height of 0.28mm and you have a surface that needs sanding for days.
10:00 these holes arent for air! These are for brakedust! so you get the dust in your ventilation holes so no air come trought these holes. sorry for bad english hätts ja auch auf Deutsch schreiben können.
Not quite while the ventilation holes aren't quite right the cross drilled holes are for air when braking you can get gas forming between the pad and rotor and this gives it a path to escape same for slotted rotors they also clean the pads however in this case all those holes are decorations and won't serve any real purpose
I love your craftsmanship! If only my BMW was designed with this painstaking level of attention to detail and quality!😂 Great job Johnny, love your videos. Thank you, sir!
