First drag car!!

[Ritz413]

I was also running the factory settings on the esc.

Given today's results, I have backed the punch off to level 3, increased the brake force to 50%, and and backed off the timing to 15deg.

Some blue loctite where the pinion meets the motor shaft and on the set screw will help lock that sucker in place. I'm thinking that with the foams, traction compound will probably be necessary.

Hopefully the slicks will help out a bit. But having no suspension will make for minimum weight transfer to the rear to really put some pressure on them to lock in. Overall I'm excited to see how they do!

Whats the size difference between the foams and the slicks?

Happen to get a running video?

I did not get a video. There was loctite on the pinion and more than 24 hours of cure time. Slicks should arrive today, once I get em mounted we can have a direct size comparison. There is dampening in the back with the damper rod...but not suspension. That is also just guessed at for now as far as how much tension needs to be on it.

Thats sick! Using a rod instead of shocks. Genius, probably saves a lot of weight and makes tuning weight transfer a lot easier

This rod, that has a rubber tube for flex, and a shaft collar to adjust the preload.

The other end...

Tire width will be improved

So much better looking....

Are those belted? I feel like when they balloon they will rub on the chassis

They do not appear to be belted. Most I looked at were. I had concerns about clearance with the frame just mounting them...so I went with the cheapest option available.
Off the wall question has anyone experimented with any at home reinforcing? Drywall, or roofing reinforcing tapes glued on the inside etc?

Bald eagles aren't belted and have a tendency to balloon pretty heavy at higher speeds, but theyre super light and hook really well when conditioned properly, and can make for a pretty quick tire with the right setup. Now that i think about it, the ballooning almost acts like a transmission shifting up as the tire gradually increases diameter. So in theory you could run a smaller pinion to increase initial acceleration, then allow the ballooning effect and motor timing top off the top speed.

Downside is ballooned tires are highly unstable in at no prep trap speeds.

Some of the speed runners have used fishing line to keep the tires from ballooning, but they have tread that they can run it through. Maybe if you get it just tight enough in the center? Might be worth a shot.

Just found This video where he used gorilla tape inside the wheel. Looked like it worked alright. Id be concerned about balance and reliability tho

 

[Ritz413]

Well ....progress has never been made without trying some new stuff....I mean of course they are belted.

Perfectly trimmed drywall tape...

A liberal amount of permanent spray adhesive...
And

And permanently "clamp" with the foam. .

 

[Ritz413]

There super soft compound, and if this works....I've got made in USA drag slicks for 21.99

And the glorious addition of a free sticker for added performance

I love how narrow the track width looks with those those 1/10 NP wheels. Looks like a true pro mod.

Yes sir!! I have been after the big slicks since day 1....if for no other reason than they look right to me. Now it looks like they may yield a performance advantage too...I hope

What size is the ball link under that housing?

 

[Ritz413]

What size is the ball link under that housing?

And 2 perfectly balanced wheels...with less clay than I thought it would take given the size

 

[Ritz413]

Tire balloon will be an issue as expected
