CASTLE, OMG! I had a 7700KV Mamba Brushless motor and ESC from Castle Creations in my 1/10 scale on road like, 10 years ago. It was... ridiculous. Following with GREAT interest.
There hasn't been another open class feather weight competition since but I will be fighting Vanguard again! I used Brushless motors for drive (for the first time ever) with 3D Printed gears in it, and they worked pretty darn good. SimonK firmware for the esc's.
Maker's Muse Sorry to hear of the fraud...hopefully you'll get through it. Question though: Why do almost no Additive Manufacturing Machines (3D printer is a misnomer) have closed loop control? It seems like for the high end machines (During the school year I have access to a UPrint SE) it would be pocket change to implement.
I was looking at this stuff thinking combat robots! If this fails he has the stuff for a half decent bot.
All my 1/10 and 1/8 scale motors are insane! I'm excited to see what happens with this. The torque amount will be insane. I wonder if they will use the castle link to slow down the torque ramp so they don't break parts.
FYI, simonk is pretty oldschool nowadays. The drone racing industry has improved ESC's at an amazing pace, both firmware and hardware. You can get 20A esc's that are just about the size of two thumbnails =)
And castle does great stuff. I suspect the monsters used in this video support logging etc, which makes it possible to connect to a computer and check the actual amps drawn. I have a castle esc on my RC heli, it has served me well for many years now!
Joel, you need to put an FPV system on your car. You could "drive" the car from the car's point of view!
I LOVE this idea.
Great idea
Agreed on this idea, could 3d print some gimbals/camera mount/holder, etc.
Realtime fpv would be very lag for some reasons
I fly race drones at 70mph, if there isn't enough lag to matter for me, latency won't be an issue for Joel's car lol
Been looking forward to the tech side of this ever since you first started it. Huge thanks to Robert for bringing his tech experience, I sure hope we will be seeing a lot more of you.
Love that he’s not afraid to ask questions and it informs the viewers as well
Finally. Ive been waiting for another update for ages. :p
The joy on Joel's face is priceless
Really cool to see a shout out to Ivan Miranda and attributing his footage. Nice work on this Joel.
I'm from Brazil, I do not speak English. But its explanations are so good that you can understand it here in Brazil. Good video and I'll be with you here, grateful.
Lol, "That's awesome, because we have a chance to go fast enough to be dangerous."
Quality rc project right there. And majestic beard too.
Vulcan high5's \V/_
So yeah be VERY careful driving it. I put mine together about 2 weeks ago (normal size). The front and rear wings pretty much will shatter if you impact anything are any sort of reasonable speed. I ended up reprinting my wings in flex material so they wouldn’t break so easily. I printed my tires using 85A TPU and they work surprisingly well.
Also, the rear axle can and will snap if you give it too much oomph or try to brake too quickly (again, learned the hard way). I reprinted that in PETG with 4 walls and more infill. I also had a front right axle snap on me.
In short - have spare parts printed and handy. You WILL need them!!!
If I remember correctly I think his rear axle is just a printed shell epoxied around a metal shaft but given that the flats driving the wheels are part of the printed item it still might have some issues especially if the printed part tries to wrap under acceleration and shears the glue bond. I'm interested to see if it will hold up or not though. Also, I think they could definitely make 3d printed tires work out of a softer material if they go in and change the design, however I think with him just scaling everything 4x that the resulting tire will be so much plastic because of the increased thickness that they won't have enough flex to provide any grip.
it;s a POS...All the weight to the body for nothing....POWERWHEELS are R/C
they just gear it so it dosnt go fast...they only have 550 brushed motors in them.FFS..You can run it on 18V to make it do 10mph..with a 50 lb kid in it...
If you were into R/C..you can build a 1/4 F1..Keep it under 15lb.
It would be dangerous....People make 1/8 go over 100 MPH.
The body is niether here or there...it's just thin lexen ( stupid light)..They work
out the drive train system first.
You need to stop trying to make everything out PLASTIC...FFS
it CAN'T handle the HEAT or TORQUE
Finally an update on the car. This is amazing, it shows what you can achieve with 3d printing. I hope you can make it work whitout any trouble. Hope to see more videos of the car soon. Good luck.
So happy to see Joel shout out Ivan! Would love to see you two work together.
Yay!
Ivan Miranda OMG Please make this happen!!!
Finally! The moment we have patiently been waiting for! Thanks for the update, guys!
I bet for the tires you could paint flex seal or some kind of other rubber like paint on the outside to get you some traction. Probably not very durable, but I would think it would work.
Austin Randolph it would but as you said its not really durable
*chrashes the car* That's a lot of damage
Why not use isolation tape on it?
Dammit you beat me to it
WE NEED PHIL
I like this series. Using the 3D printing's downsides to introduce traditional methods and their advantages and disadvantages.
Hurray! I love this project.
CRISP! I use a Castle Creations 80-amp high-voltage speed controller in my Giant-Scale RC P-51 plane. It has worked great for years!
I freaking love this! This format, the presentation, delivery... All of it, perfect!
33 volts at 60 amps. for those who want some scale there, thats almost 2 kilowatts of power... or roughly 10 times as much power as the 3D printer used to create the car
I think you might want This Old Tony (he is like a one man precision TH-cam Ateam) , not only can he teach you the dark arts of cutting metal (and other things I am sure), but I bet he could make you some interesting components too should you get into trouble and need re-enforcement's.
I’m glad you are continuing on this awesome project!
I've been waiting for this episode anxiously. Thank you joel
This looks like some serious power. Looking forward to when you get it to drive around with these giant motors. Great stuff!!!
This is proper commitment right here!
I'd suggest using high temp plastics for mounting the electronics, as the PLA would melt with the heat that the motors, servo and the escs would produce.
You should install an fpv camera on it
It's based on an F1 car, they have a nice cockpit to put it in.
Awesome project and looking forward to watching the progress.
Awesome!! Looks like you found the right person to make this a reality. Can't wait.
I love this series keep it coming! cant wait to see it driving!!!
Joel this is a great update. Oh seeing your look when he started talking about the motors. From then on you had the kid in a candy store look. With 10 bucks burning a hole in his pocket. Looking like this is gonna be fun indeed. Looking forward to the 3dpn F1 race season. :)
This project just leveled up!!
Incredibly interesting project you have here. Watching with abounding interest.
I've been flying rc planes for a couple of years and have never seen a transmitter that nuts. That is so cool, I would never need 32 channels but I would like that many switches 😂
Can't wait to see the build and test drive! :D
just seeing that servo makes me happy!
I need to get my hands on more electronics. I cant wait to see this sucker on the road.
epic way to explain the R/C electronics super sweet video !
I've been wondering when this update would come. I'm glad it's finally here!
Look's like we gonna see the the most big and expensive 3d printed RC car ever crashed
mariano0312 its going to rip itself apart
Ive been looking forward to this!
I don't care if this thing does just five mph I so want to see it work. Such an amazing project.
That's so cool of them to give you those motors.
I was laughing so much through most of this, just the size and power of everything is just absolutely mad.
I love your guys' progress! I drive a 1/10 2wd buggy at home and I love watching RC videos, and seeing rc components in a new way of rc car is exciting!!! Also... don't you guys need a differential gear? Or do F1 cars need it?
awsome!!! great video!
That is awesome project!!! :)
Looking good Joel. Maybe Teflon bushings instead of bearings? Glue a thin one on the OD of the shaft, and glue another thin one to the ID of the bore? Easily machinable to fit exactly, if needed. I'm sure some of your subscribers, or someone you know has that capability.
i was always waiting for this video
Those motors are going to be such overkill :D those tires will never last, and those batteries will never supply the sufficient current. Love this project already
This should be BIG fun ! Go Robert ! Seems like chain drive would be better than belt drive, but I am sure Robert has a reason for picking belt drive.
I don't think you need to worry about the spur gears. I'm running a 30kg tank on two drivetrains, one per side. Each drivetrain has a 2 Nm motor, with a pinion that has 11 teeth, 2mm module, and 25 degree pressure angle, from PLA, 100% infill and 4 walls on 0.4mm nozzle. The gear is skipping teeth sometimes because the motor mounts are insufficiently stiff and the pinion and gear push each other away. Your motors are about 30 times more powerful than mine, but I'm quite sure that's because they spin over 50 times faster, not because they have more torque.
Love this build
You and your words, I love it
I was wondering what happened to this project, good to know it's on it's way. Keep up the good work, high five :D
Love it! Can't wait until the next one! We think alike..."Go Big or go home" haha
I'm in the process of making an E-Bike, I just had sixty Sanyo 18650GA's arrive in the post. Now I have to finish the CAD for my very oddly shaped battery pack, then I can get on with the 3D printing...so much printing :)
I've made the open rc f1 car in 2x scale, also radio controlled with 2 700watt electric engines. I used full pla wheels with rubber tape for traction but the engines are to powerfull, 1 engine is probably enough😅 I love your 4x build and keep up the good work!
It's plastic Robert!!! Haha. Great video!
Great video. Great expert!
This is great!!
this thing is going to be awesome
Any updates. So looking forward to see this thing tear it up.
@3dprintingnerd, 6810 bearings come close to ID and OD can be solved with a bushing. These are 50mm ID 65mm OD and 7mm wide. Allthough these are much slimmer they can easily take the radial load. RPM up to 9000 with oil.
Alternative is the 6811, 55mm ID 72mm OD
This is great a great video.
WHEN IS THE NEXT VIDEO?!!!! Can't wait
You guys should add headlights and turning signals since you have an extra 30 channels
Alex Dunda if it were mine I'd put a drone flight controller on it for a steering gyro. The frsky radio does some amazing things when paired with a flight controller. (like support Lua scripts, yeah it has an interpreter for a scripting language! Well as long as you select that when you update the firmware ) Unfortunately there are some features to that esc that work with 2 specific futaba radios, well maybe more including flight radios but Im no futaba expert. Too rich for my blood.
In reality the receivers support either 8 or 16 channels but you can bind multiple receivers which is good for giant scale stuff so you can mount receivers and battery packs in the wings and not need to disconnect wires when you break it down. That way you don't get unfortunate disconnections and weird issues from loose wires in hard to reach places on long wires.
Anyway a flight controller can address neopixels or similar programmable led strips and boards so you can have a friken dance party on that thing if you really want to
It's an F1 car...
Yea but there is a flashing red light on the rear of the car indicates that it is harvesting energy into it's ERS (Energy Recovery System). That means it could be potentially slower in the corners. This acts as a warning for the driver following the car.
you should print the rim and use foam as the tire. Foam tires are commonly used in onroad rc racing and speed runs. they provide great traction and tend to not blow off the rim at high speeds.
This is very similar to what we do in FIRST Robotics! Our robots are aluminum though with the occasional 3D printed part, they weigh up to 120 lbs and they run on 12 volts.
Im so excited to see this thing rip down the road
cant waite to see it go
You could try using a 3D printed gear bearing, just to keep the car in printed parts. It probably should contain a lot of smaller rollers in it, since the outer and inner rings makes the bearing so slim.
I AM SO EXCITED!
Nice apron in the background, Joel! #teambjb
I already use Castle, and I definitely recommend them.
Yes I agree Castle makes the best stuff the only thing that worries me is I wonder what the throw is for the steering linkage as opposed to that servo is it going to turn enough? Maybe a linear actuator would be better can't wait to see the next video!!!
A servo will be better trust me.
To quote Joel, this is “redonkyluss”!
Robin Gingerich yeah they are going way to power happy. A castle motor is pushing it.
Hopefully it'll push it far and fast.
for the testing ground you should look up PGP motorsports park near Covington WA. It is the largest out door gokart track in the US. Hi Angus! my fist electric RC was also powered by a 7700kv castle they were blazing fast
I'm digging this build, can't wait to see it rolling. Red Bull Racing F1 FTW and Go team Hass F1.
I see a couple things that might be an issue: batteries won't be able to pull enough amps for each speed control. Since the XLX only supports 8S, I think performance LIPO batteries are probably a better choice than recycled low current 18650s. That Hitec servo needs to be run on its own, it can't be run off the XLX internal BEC (so maybe a Castle BEC Pro V2 with it's own 7.2v pack is probably best).
Lastly, I think the OpenTX remote at least to start isn't probably the right choice, it'll make driving the car harder than it would be normally. I'd say a Futaba 4 channel surface/pistal style remote is a better choice.
Otherwise I think you guys are on the right track :)
Awesome👍👍
im glad i subbed
Awesome video with awesome nerds.This will be awesome! :D
Robert is one incredibly smart guy
If you want to use only 3d printed parts, for the bearing IGUS filament could be a good choice.
NO JOEL!! Print the belts with a flexible material like TPU and CARBON FILAMENT on a MARKFORGED!!
@Robert that beard is epic! looking forward to similar content from this channel
Orderd A ultimaker 3 hope to print your stuff!
After watching all of your videos in finally ordered my 3d printer. I will have to assemble it first and I'm so tempted to just print something big first. What would you recommend I print first to calibrate my settings?
This remote is huge, but unlike most RC remotes looks quite nice :)
Well at least it's in proportion to the actual RC car :D
it is :D
Nikodem Bartnik what’s the remote called? I want one
The newwer but more affordable version is even more beautiful and comes in a few colors. The entry level model is also quite attractive if you get it with a carbon fiber looking wrap. With frsky you don't have to pay for features. Other than fewer switches and knobs and a low res monochrome screen the qx7 still has the same 32channels (assuming multiple receivers bound to the same model in memory) , telemetry, voice, and receiver compatibility. The horus models are more beautiful but frsky isn't elitist like say futaba where things work in specific ways and you have to pay for features. $110 gets you a geeks dream of a transmitter
It's the FrSky Horus X12S, and the thing is EXPENSIVE. I don't care how well a remote looks as long as it costs 1/8th of that and has most of the same features OK?
Those tires are "for testing purposes only". Ike would be proud.
Oh, side note- the spec on the motors is 120amps and 25.2v ( max ratings )- a little bit of math later and that gives us a maximum of 3024 watts, or 4 Horse power- each. 8 HP total on a model weighing ~50lbs = ~360 Hp per ( metric ) ton. Not too shabby at all- my 1/8 scale trucks run at about 500Hp per ton, but they ofcourse are far lighter and use a single, smaller motor ( 1515 2200kv on 5s lipo ). This thing will be a beast- make sure you find a big, open area to test it...
Idea for the wheels: Nylon rim (almost full wheel/tire diameter) that has a sheet of rubber (neoprene foam rubber for example) glued to it's running surface. This may sound weird but it is quite similar to the wheel construction of regular RC racing cars.
I expect it to be difficult to get a tire that is flat on top in the same scale (size) that isn't really heavy. And considering the fact that most of the construction is 3D printed you really want to limit the amount of forces and stress put on the frame and mechanics.
Nice!
very nice episode, realy like the "cross over"if you get what I mean...
Also, are you going to have independent drive to each rear wheel? (I.e, one motor drives the left, and one drives the right). If so, you might think about adding some encoders to the wheels (on all 4 wheels), and using an Arduino to set up a traction control system... (in a loop, if the sensed speed of a rear wheel is too much higher than the front wheel’s speed, reduce that wheel motor’s throttle signal). The RC receiver would connect to the Arduino, and the Arduino would filter the throttle signal before passing it along to the ESCs. If possible, you’d probably want to set the ESCs up for a high update rate (similar to the way that quadcopter ESCs are setup), and disable any filters built into the ESCs... 🤔
Can’t wait.
for normal people get a taranis qx7, no need to spend 5-6x the amount of money on something that does the same :)
That is the most powerful brushless motor ever made, i dont think you can kind of compare them
the fuck are you talking about, im talking about transmitter
No u
No, it's not even close to the biggest.
Hey Joel! I have an off topic (in relation to the video) question for you. Do you think you could make a video about like, the care and maintenance you can do with/for 3D printers? I see a lot of videos on reviews and what not, but not a whole lot on like how to replace a belt when the belt isn't pre-joined or what not. Figure it could be a cool little "miniseries" about taking care of your printers :D
You need a FPV cam with Pan/Tilt and a head mounted display with headtracker. :P
Seems like Joel's buddy flies fpv (judging that he chose an fr sky radio system, not a typical rc car system from like spectrum or something), so he should definitely put a tiny whoop cam on top and hook Joel up with some Fatsharks!
Have a look at fingetech timing belts, great for this application
