Default building offroad track, and want advice

I am just getting into high dollar RC's. I have several friends who have been doing it for several years, but me and my other buddy are brand new.

We want to build a couple tracks this year and need to find a good dirt mixture. Clay is not an option because I can't find anywhere that even knows what I'm asking for.

Anyway, I'm wondering about how well a crushed limestone and topsoil mixture would work. Crushed limestone gets almost as hard as concrete and packs very, very well. In theory it sounds like a great mixture, but like I said it is a guess, and I have no idea how much I should mix in with the dirt.

Anyone ever tried crushed limestone? and how well did it work for you?

Sounds like you would wear out tires rather quickly with limestone.

Hey man, check out me and my friend's track at www.PalmdesertRCraceway.com. We used crap dirt with gravel and just terrorible stuff and tried our best to get it out, then we took some rubberish liquid goop stuff that you buy by the 125 gallon tote and we mixed that with water( first 2 coats 5% glue stuff 95% water, and the next two we used 10% and 90 water) This compound is SICK and with a xxxt-CR with a 19turn brushed motor it pulls wheelies out of every turn. After two days with my calibers, they were completly worn down, but they work just as good as slicks as brand new so dont be afraid to try something new. Check out the first video in the video section then another should pop up with an electric 8th scale buggy and check out the crazy traction. anyway let us know how it goes!

I thought that might be a problem, but I'm wondering if just maybe say a 20% limestone mix would make the dirt a little more stable, and easier to get a tight pack with it.

oh yeah give it a shot, limestone is kinda abrasive on the tires but i think thats the worst case scenario.

Only one problem with limestone , it will suck up any moisture and track will always be dry . It does get really hard and abrasive so unless you want to wear through tires a weekend just stick with dirt , and mix calcium chloride or liquid laundry detergent with the water or powder with dirt .

We run the track dry at the Palm Desert track. The only thing bad about the glue is that when the cars nosedive and case the jumps, you can see the glue peels off the track sometimes. The thing about the tires is, you will have the same amount of traction with new and bald tires. Once you get past the tread design to where the tires are bald you can run alot until the tires get really thin.

I have a huge pile (must be 70yards) of silt im going to try and use... its this light tan color and its kinda like clay.. its in my yard under a foot of top soil.


this is my backyard.. before i dug a pond (where the wet spot is) now there is a 60' x 100' pond and a huge hill of silty soil.


I dont know how well it will work, and im not too sure if my neighbors will like nitro.. my buds have nitro and i have brushless.

The pond silt should work well. Very fine stuff. Every now and then use a little lime for dust control, mix in to the first 2-3 inches with a tiller and roll it, water it kinda wet, let sit a day and should be good to go for 4-5 weeks. The finer the durt the easyer to work but will dust up in no time. Broom it back into shape, wet it some and run it. Will blue grove inside nice but outside is all fluff so staying in race lane means everything. Will drive everyone nuts trying to pick the right tire. Oh yeh, the good red clay is from south Ga.
