I’m involved with a lot of high level rc drifting and racing, and I know I and others would kill to have a real force feedback system. Right now in drifting we rely heavily on electronic gyros to control the car, but force feedback would give more control to the driver, which a lot of people are missing. Some have tried non assisted drifting but it is incredibly difficult as you can guess when there is nothing but visual cues to go off of

Exactly what I was looking for, was even planning to do one myself

A year passed - do it!))

hello bhai suspension kaise banate hain bataiye

You definitely deserve way more subscribers ! Keep up the good work !

i have a cuestion, could you give me the .f3z to download the screw compresor?? because the link you are giving in the comments do not let me open it on fusion360 (sorry for my english i am from spain)

Hey man, I really wanna turk my HyperGo RC car into a time attack machine but dont know exactly where to start, any recommendations?

I think you need to characterise your fans for flow and pressure. Water column is an easy test for pressure. Your axial fans are quite likely in aerodynamic stall due to the inlet restriction and I think only a centrifugal type would ever work (maybe multi-stage axial, but that's very difficult). I think pressure is going to be more important to you than flow. Per the fan affinity laws, you want smaller diameter and higher RPM. If you want to cheat, just use a dyson impeller and motor, something like 0.28bar sealed pressure @ 125,000 RPM. You'll need 6S li-ion, though.

18:30 would be good to see power here, too. Grams/watt is the key. Although grams-downforce/grams-added is maybe more key.

Super cool project. That thing is shaking itself apart though. You might want to use locking nuts such as din 985 or similar ones. It's not perfect preventing the loss of preload but at least the nuts shouldn't completely come off.

Look into x8 cinelifter drones. They are a octocopter with a small layout and use contra rotating props. Generally the consensus there is the second fan (props) is producing 30% less thrust because of the dirty air. They do the same thing with a higher pitch blade for the secondary fan though so parts in the right direction for sure

The quality of your videos is really outstanding

what if instead of using a vacuum cleaner setup you instead just used a normal mesh filter but with a blown diffuser setup? would there be a significant loss in efficiency? in theory it would eliminate all wear and tear on the fan and even save some weight/volume. presuming its less efficient that would just mean you have more thrust to play around with and could even try a blown wing for extra static downforce

What a fun process to follow along with. I wonder how much more room there is for improvement with a hypothetically optimal torque vectoring setup that considered weight transfer. I was actually shocked that it made such a large difference at high speeds. 0.4g is not insignificant at all considering the amount of downforce already involved.

Awesome video btw

Premier Aerodynamics made a video just for you named: Using Artificial Suction To Improve Lap Times Podcast 215 link: ruclips.net/video/HazZf2Z8Qrw/видео.html

This is one of my favorite channels! Keep up the great work.

Why are axial and contra so difficult to optimize for compared to centrifugal? What do plane mfg's know that we dont?

God I love this channel

The fan needs to be balanced.-MSC-

I feel like contra-rotating is more for high flow, low rpm applications like a plane or boat propeller, instead of high-speed fans like these.

Such a great vid! Could you post your fan's cad somewhere? I'd really like to use this in my project!

Is there any chance I could get the files for the mixed flow design? I'm trying to make a robot for a school competition

Nice work. I would suggest you move the heavy wheel motors off the wheels and put them in the center with driveshafts.

amazing, DirectDriveWheel for RC!!!!

If stuff isn't 'sploding, you aren't pushing it hard enough. 😜

Wow, finally found some great stuff on YT. Finding this type of content nowadays, when there is so much empty and useless stuff all around, is certainly a breath of fresh air.

good vid.. slick tranny !!!!

Hi, I'm a mechanical engineer mostly doing hydraulic stuff for test systems in the automotive industry. Your system is impressive. I've seen some issues which caused the leakage and the which will damage your cylinder over time. First of all the shaft seal has to be connected to the suction side of your pump, so it wont be pushed out when the pressure is rising. Second, your cylinder is bolted down to the table, therefore the piston rod is bending and putting untypical forces to the cylinder head. Your piston rod will wear down the cylinder head fast and it will beginn to leak. Mount your Cylinder in a way it can swivel with your construction. You have negative forces put on your cylinder. Therefore it retracts to fast, almost with no resistance than friction, in industrial applications this can cause heavy damages. You have to preload the retraction movement with at least in line a relief valve or better with a counter-balance valve. In your case this doesn't matter, but it is something you should be aware of. But really nicely done. Kind regards and a happy new year!

Thank you hoping I can modify this to work with my rescued jack Russel who was thrown out of a car and has neurological issues which causes balance issues. Thanks

that would be amazing with my sim rig and some fpv

हेलो भाई इस सस्पेंशन काम कैसे कर रहा है बताइए ऊपर नीचे झटका को अब जॉब करने वाला

Pair this with the video I saw using a Logitech wheel, fancy transmitter, and FPV goggles with a head tracked 3-axis gimbal camera and you'll never peel me off it

I absolutely love the amount of engineering put into this

Good luck with your project. It looks very interesting.

Hi Sir, I'm a mechanical student studying in india. I really liked the ideas of design that you implemented on RC car and I've also in the same project but with different ideas so can you tell me where I can get those frame and wishbone etc.,in india. That would be helpful for me and my project

Hi! Do you know where I can acess the CAD documents?

Failure is not an option. It's a guarantee on the way to success.

Como estas, por que no tratas de hacer lo contrario y crear un turbo expansor que funciones con aire comprimido para generar energia

I have the Hakko FX-888D soldering station, too. I love this kit so much. I use it for all my electronics needs. I've owned it for at least 7 years.

Take a page from the Chaparral 2J suction cars. Add a suction fan to get your downforce and use the exhaust for additional thrust. Then you can clean up your profiles even more.

Lost pla casting using zamax. I think you'd be surprised at just how easy 3d metal prints are with rubber coated screws this would be an interesting project

Still this a really cool demonstration to show kids how these compressor work. I think this is awesome. I know the ones used in industrial look like they have a rubber coating on them. Maybe try to spray flex seal on them and see how it does

That pavement looked like the moon’s surface, it was quite rough.

I didn't watch the full video, but did you try putting a small horizontal tail on the rear wheel to keep it pressed to the ground?

What is the vehicule’s model ?

Cool video. I like the detailed analysis of your design process. Good luck with the next version(s).

I am looking at your rear steering mechanism, and thinking you can do away with the external servo horn entirely if you allow the pivot to be in line with the servo output. In your speed runs, the steering position will always be straight or near straight while under way, so you could save some weight and aero drag by doing this. I also suspect that above 60mph or so that most of your steering authority comes from the aero rather than any wheels that you would be using for the rear.

F1 Transmission V4 v35.zip in your github was it supposed to be the same as the test prints?
