Does anyone know of any information on making a RC track, something that explains everything from beginning to end?

For example, I heard of someone using a roller to pack the dirt after its been laid, is that the best tool, is there something better? How or or what is the best way to plan for jumps in a track, as far as ramp placement?

I've seen RC Car actions website, describing a few things, (http://www.rccaraction.com/rc/articles/howto_track.asp), maybe one or two others, but is there anything else out there with a little more information that is listed there?

Sorry I see you all read have this. http://www.rccaraction.com/rc/articles/howto_track.asp

Is this a track for fun in your yard?? Or one for organized racing?
Shoot for a minimum of 8ft wide lanes.
For Organized racing-
Electric 100-120ft back straight. For Nitro a little longer.
Jumps should be fun!!! NOT Car breakers. if you have multiple jumps (doubles or Triples) adjust the distance (timing) to make them challenging but not impossible to complete sucessfully.
Have fun with the layout, but don't let the difficulty of the track be the main determing factor in who wins the race instead of the drivers set up and driving skills.

After several YEARS of trying to find track building and design info on the web, I went ahead and did it on my own, no guidelines. I have a 7,000 square foot track in my backyard. The last two years, I have used the track diagram from RC Car Action's coverage of the Gas Nationals. I use a 40 hp tractor with a rototiller to bust up the ground, after it has been treated with roundup to kill the weeds. My neighbor lets me use his 4 wheeler with spray tank for the weed killer application. I go over the ground at least four times, maybe a day or two apart. This allows it to dry and break up better. Then I measure out a grid, planting landscape flags every 10 feet all around the perimeter. I then use orange pavement marking paint to get the basic outline of the lanes from my plan. Next I roll the track with my mower pulling the roller. After that I lay down the black 4" flexible drain hose to make the lanes. I use landscape pins every ten feet to keep them in the ground. I also take the rocks we pick up after roto-tilling, and put them inside the ends of the hose, to help keep them from curling or getting moved too much from truck impacts. This year I took an old swing set and made a driver's stand out of it. Very easy, and cheap. I try and add something new each year. This year the design allowed use to race a very technical center section, and by moving just two pieces of lane pipe, we could convert it to a fast oval, with a chicane in one end. Our first attempt at track building won us some prizes from RC Car magazine, and my sons got their picture in Skinny's column.

RCP Tracks has a link to a "Track Builder" on its website.

Although it is geared more toward onroad, one is still able to configure the tracks and save the file. RCP Tracks is also supposed to be adding new sections and tile types to its tracks, so eventually it will probably upgrade the track builder program. There was also another program which was available for download though I no longer have a link to it.

Off course, Roar Racing has specifics on lane widths, barriers and so on in the Roar Rules which can be used with the RCP Track Builder program for specifics once the layout is designed.
