Limitless LibertyMkiii's crazy belt drive car project

[Monster Dork]

Caster is critical for straight line stability. All of the self correcting tendency comes from caster, and if it's off in the wrong way, you'll get the broken shopping cart wheel wobble! Some is built in to your setup already from what I can see.

Ackerman isn't applicable here. Your CG is über low and your wheelbase is über long, you just want to make your U-turn without dragging one wheel too much.

I appreciate the guidance. I may re-design that front block with 10 degrees positive caster.
For now it appears I am ok

I checked the PDF/Article for Nic's 202mph car, and lucky enough for me he noted his caster setting in this....

Zero caster is a little sketchy, but that's what testing and revision is for! Then again, a rollerskate doesn't have any effective caster, and that's what this is, a rollerskate that can do a u-turn at the ends of the course. You can cross that bridge when you come to it, if you even come to it at all. You might just fly past it at 204 mph...

Oof...yeah that's a trek. Try Caddo Mills Municipal Airfield...could be a possibility.

I have family near Caddo Mills.

Right on! I see you’re NY, but I wonder how many Texans are on this forum.

Yessir. That’s my 1:1 toy.

There may be some private airfields, part of HOA type communities that might be willing to let you run.

Or defunct airfields. Reno's air race airfield was once national guard, and is still accessible for car clubs as far as I know. My local airfield moved a half mile over due to a degraded surface, and is used by several auto racing clubs and a RC airplane club under city agreements. I can go out there and speed run the 1/4 mile drag strip as long as nobody is using it. I think this is common. There are also unmanned airstrips, but the rules might not be so straightforward.

There is one I know of in Mineral Wells TX that I used to do auto-club drifting events at. The problem as you mentioned is the degraded surface and vegetation started to take over.

Lets start a Gofundme to resurface it

Waiting on a tool mentioned in post #161, the pulleys, belts, and motor.

With that in mind I moved back to working on the body. I am almost done with the initial body filler over the 3d print. Next up will be primer, followed by sanding, more sanding, primer/body filler, and more sanding till it is all perfect.

Once I reach that point I can form a mold off this shape.

I just had a vision of you sanding on that body mould as Demi Moore with the ghost of Patrick Swayze with the Righteous Brothers crooning in the background...

LibertyMKiii let me know if you need a plane ticket, if you can fly Southwest I have several hundred thousand points. I would be willing to donate round trip tickets for you, so you won’t have to worry about it.

Wow thank you!
Southwest has a main hub here in Dallas so that could be an option. I'll keep everyone posted on a run spot determination.
Again the member here are amazing and just blow me away! I had 2 others reach out and donated, but didn't want their names mentioned.

This project still has a long way to go before I can run it. I don't expect testing to go perfect. This setup is full of things that are un-tested...
The other tricky part would be traveling with LiPo batteries

I should have some good updates by this weekend as many parts are coming in this week finally!!! Belts, pulleys, motor, and the tool for pressing the pins.

Wait? You looking for sponcers?
