That's An awesome idea.

Yeah like active aero

@@EngineeringAfterHours so do it!

​@@glennhuman6936 Is not possible, fans can't so fast speed up and slow down when is needed

Thanks! It pains me to see the aero design issues with some of the so called speed bodies out there. Power is useless if you can't get enough traction to overcome drag. I'm hoping to touch on max acceleration curves and the relationship with downforce and drag soon.

I was thinking the exact same thing. That chassis is too short to get any real stability. Should've tried something Arrma...just saying. LOL Maybe a Typhon or Talion chassis probably would've worked a little better.

separate aerodynamic body suspended to the chassics

Thanks! I really wish I could have gotten the 1s...but well get it on something else.

I hope to pass the 3D models on to a other youtuber working a pretty awesome limitless build. So while I'm through with it...maybe the fan car isn't dead. On the limitless front, I really want to redo all the aero to be real wings with much more downforce and less drag. Then I can sell the upgrade kits if people want to play with aero themselves.

@@EngineeringAfterHours that's awesome, a limitless with improved aero sounds great! What body are you using on the slash in this project?

It's a losi 8ight body. The 4.0 I believe

@@EngineeringAfterHours sorry, I was actually curious about the super car looking body from the slash? Thank you so much for the replies though!

@@fattmatt805 I'm not sure which one you mean. The white one is an arrma typhon if that's the one you're talking about. I've 3D printed several parts as well.

Welcome and Thank you! My next video is planned to cover a lot of math on downforce and acceleration for dragsters that I think will kee0 adding to the fun with physics.

Thanks! Can't wait for some fresh builds that aren't as high maintenence

@@EngineeringAfterHours haha me too! I'm about to upload a video of my latest deranged RC creation. It's going to be low maintenance because it is a sloppy thin sheet metal decorative Christmas truck I bought from Ross department store for .49 cents🤣. Mounting it to my SCX10.2. it's going to be cool driving something that will dent and rust

Thanks! Happy to hear

I'm not sure what you mean...are you referring just to the framing of the shot? I'm open to filming tips anytime so let me know!

@@EngineeringAfterHours Yeah, just the framing. The rest is gold! The content you make is really great and I just want to make it that 1% better. Usually you only want to leave the tiniest space above your head before cutting off the shot at the top. Hopefully that's helpful!

You gotta carry the project on for us now! This is my last go at it lol

It's a tough call to say whether it's worth it or not. They're a pain to work with because of how much power they draw and constantly having to charge batteries. And of course filming with 4 different cameras adds to the complexity of the setup. They're also very dirty, and if you don't have the skirt just right, they create a ton of drag. But there's really no other way to get that much low speed acceleration on a road course. So if you need low speed downforce it'll win every time. I may do a respin of it eventually...but it'll be a big redesign and that's why I destroyed the undertray, body and fan housings. i may try more of a t.50 style with my ground effects. As far as real world racing...I think it's good They're banned. But it's certainly fun to something able to move around like that. The accelerator and steering is instant when it's working well.

Thanks! I have considered trying to make a physics course that uses racing as the examples but an entire course is a lot of work.

Good luck! Biomed is definitely an incredibly hard major...I mean all engineering majors are but biomed is very niche as well as being engineering.

Haha...definitely. Or "why locking differentials matter"

Vertical stabilizers will come on a car at some point. Sharkfins or huge endplates. As for the fan car...im hoping to let someone else shoot for MK4

I understand toe and worked with several different front toe angles through this video. I think you're just not aware of what you're seeing and making assumptions. You're also incorrect about toe in general. Positive toe stabilizes a vehicle at the expense of turning ability, negative front toe improves cornering ability at the expense of straight line stability. 1 - rear toe on these cars is a fixed 2.5 degrees. I'm not custom designing A arms first off. 2 - the rear toe angle on this car straightens under acceleration because the structure is relatively flexible. Parked toe angle doesn't mean much in terms of handling performance when it's so different than the realized toe under acceleration. 3 - the static toe angle on this car is barely greater than those used in open wheels series. Those cases use positive toe in the rear and negative up front. The biggest difference in my case was actually running slightly positive front toe to improve straight line stability during 0-60 runs.

Thank you

Thanks! It's been a lot of work and lucky timing.

@@EngineeringAfterHours I think you may have exceptional skills in masonry work for what I saw, and even though I didn't care for the way the fence post were showing, it looks vary neatly done. "Great job on the back yard." "Thumbs up."

I think locked differentials would have solved the problem. I'm not sure there are tires much stickier than the GRPs I was using...but when they pick up dirt they lose that stick so track prep is king. I wish i had my nobel NB4 to change the throttle maps, that may have gotten me there without the locked diffs.

Yeah I'm definitely down to chat. I can share files as well if you want to save a little trouble. Realistically the harder part is seal integrity across anything but a perfect surface.

It's a little over 3 lbs, but most of the run is closer to 1 lb because most of the run is under 60 mph.

That's the first I've heard of this...can you share a link to it?

I think you're right. Where I live the majority of New roads are concrete and all have expansion joints. I'm going to try and get clearance to test at a local drag strip for other speed cars.

@@EngineeringAfterHours The question is: if you find a nice flat test strip, will you be able to resist trying another incarnation of fan car?

@@drangus3468 I'd probably go rocket car first!

Haha great catch

That's what I like to hear! Thanks for watching.

Pun intended?! :)

Insta360 go 2

6000A for 60hp (45000W) would be true on 2S power. On 8S it would only require 1340A, devided over 4 esc's that's 334A each. That's doable, assuming the batteries are dedicated per esc

The motor is a castle 1515 with monster mamba x esc. The battery is the spektrum 5s 100C 3200mah. I've watched raz's videos a few times and he's technically calculating his electrical power right. But the mechanical power is going to be way less than that. He's going to lose a lot through motor and wsc efficiency, the through the driveline. Either way I do want to see what his 4 motor car can do. If he fixes the aero it should be a top speed contender.

Haha yes I have. I want a wheelie bar that connects to TSM and keeps me straight when wheels are up

@@EngineeringAfterHours I have to admit that sounds really cool. I want it to optimize acceleration with 8S. The power is too much.

Longer wheelbase is a good idea and something that will help me in multiple areas.

If only I could get that many views lol

I'm running a traxxas TSM system on this car.

@@EngineeringAfterHours ok, i don't understand why its not working then. It seems like like it was correcting the steering in the wrong direction and making it spin uncontrollably.

@@engineerpauly7480 it can't respond fast enough.

Much greater things to come. I'm just wrapping up the fan car series for now :)

This is a tough one. The creality ender was the big name for a low cost printer when I purchased mine...but I know those come with some maintenence. I paid a premium for the dremel 3D45 just so I didn't have to deal with any issues or print failures.

Anything specific you can think of editing wise that will improve it?

I considered it, but the car is geared for a specific speed and it was hard to maintain that balance. I also would have to do both, torque limit and change the tire. I still should have done it regardless because I think the GRPs were cooling or getting dirty mid run and losing traction. It's really hard to tell.

Lol nah...changing platforms to a proper drag car. I've got too many new builds I want to try out to spend much more time on it

@@EngineeringAfterHours fair play. Good content though 😉

Weight played a huge role in it. If arrmas weren't so damn heavy this would have been a limitless. The traxxas was far from stock too. X01 diffs, MIP Xduty shafts, steel gears...etc.

The corvette went mid engine to lower rotational inertia and improve weight distribution. If chassis length was the concern they would have just increased wheelbase.

I thought about it but actually just bought a transmitter that has the function built in. This way I don't have to deal with a potentiometer and no digital readout. I can also program an exponential curve. Perfect pass is great if you can't get the transmitters that have the function built in.

@@EngineeringAfterHours which transmitter did you go with?

Noble nb4. Wanted the high end futaba but its just too much.

I will try to sneak more math in there! Some people get a little mad if I get too technical so I'll have to be clever about it

Yes it can and is frequently above 1 on racing slicks. When they get warm they become adhesive.

Slash 4x4 vxl rolling chassis

Yes

Its a Garbage front facing cell phone camera.

Anything useful is kept. I only destroyed the useless or broken components. Even the fan ESCs will likely be reused for a desktop wind tunnel
