Speedrun Custom Wheels // 250+ MPH

[King blitz]

I haven't driven a rc car above 40mph so I don't know if you need a lot of traction but what about a plain 3d printed aluminum tire?

I'm assuming that you mean a Rim and not a tire.Right?

Here we go again an aluminum wheel would be great but how are you going bound tire to the wheel that the problem.even in full size wheel driven land speed cars are having a problem on salt not on concrete

Instead of individual dimples..
Couldn't we use 3D printed chevron pads , mounting them in similar fashion to your aluminum wheel?

How would you mount the pads that the problem

How would you mount the pads that the problem

Just like yours..
From underneath the rim surface and using a smaller inner ring to retain the chevron pads.. sandwiching them in place.

Actually I'm thinking- using a thin wall carbon fiber flat ring will work great as the "retaining ring" for an aluminum wheel. Less mass.

Don’t let this thread die. This is awesome to watch evolving potential solutions to the one single thing holding all serious speed runners back. Y'all can do it. Just saying. I’m still holding to the following approach: a thin machined aluminum wheel shod with a Kevlar reinforced “rubber band” tire with some really good glue. Make it work, you guys are smarter than me.

I wish that was my wheel four of those $35k

 

[wadedog]

That’s what they are doing here a pad of 39 Cleats sandwich been on aluminum inner ring very ez all we have to do is down size it

 

[wadedog]

I have been thinking about getting a bigger lathe . I just have a small hobby one here at home have to talk to the wife

 

[speeding_Infraction]

Just had an idea. How about have the inner ring to be a loose press fit and have it expand centrifugally to hold the rubber or foam in place.

That's going to be Very difficult to make happen..
Because as soon as the "loose" inner ring gets shifted due to any vibrations or jolts from bumps in the road ,it will cause your wheel to have a death wobble ,once it starts..
That even with ultra stiff shocks won't be able to get them back under control >> at those High speeds (160+ MPH)

Exactly Tex vibration is a problem

Sorry but that is the ugliest looking wheel I have ever seen .what speeds could you possibly get out of that before it blows up everywhere. Reminds me of fkin slinky toy.

Okay little boy that wheel has been 404 mph on the salt flats

Who you calling little

Okay little boy that wheel has been 404 mph on the salt flats

Does anyone here do speed runs with there Rc cars on salt flats didn't know that was a thing ..

I don’t think you have the - - to drive my cars

 

[Diem Turner]

I'm assuming that you mean a Rim and not a tire.Right?

I'm pretty sure he means tire. That's what the pros use. This is the rear wheel assembly of the Thrust SSC, top speed 763 mph (more than 1,200 km/h).

This is the wheel of the Bloodhound SSC (they're taking aim at breaking the 1000mph barrier).

It’s all good

It’s all good

Those two cars are jet propulsion they don’t have the problem with with wheel slipping under power

 

[King blitz]

It’s all good

When your going at them speeds wtf does it look like inside that bullet, must be just a flash of light .and how do you get all that pressure out of your cab? I would imagine at them speeds your face would be pushed back into your head ...holy fuk dude .you one brave .tough bastard
