Hey guys,

Ill make this as short as possible.

I
haven't raced at a track in probably 20years. Locally, there is no place to go. I own 14 acres and I'd like to build a track for me and my kids / friends to play on. I'd like to make it a legit sized track, i.e. length / width / jumps etc
layout and so on. where can I find some info? I want to run 1/8 scale trucks / truggies / buggies and 1/10 scale buggies for my self, but it be as all encompassing as possible.

I wouldn't be opposed to in the future perhaps opening it up for fun to a club since there is no place around that I know of, for close enough driving.

fyi.. I'm in Hamilton / oxford area Ohio

I don't think there are any real limitations or rules regarding tracks, except for the size of the land your building it on. But since you own a pretty large lot just make it to your hearts desire like seriously you have nothing holding you back, YOU HAVE 14 ACRES!

Do you want some ideas on how to layout the track or how to make ramps? What material to use for the track? How to make borders? Or are stuck on how to even start making the track? Need mire info...

here's the ROAR rule book http://www.roarracing.com/downloads/..._Rule_Book.pdf. section 2 gives track specs. they dont specify hight if drivers stand, probably because of building codes. from what i've seen, having the floor of the stand about 5-6 feet higher then the front straight is a sufficient minimum height. 8-10 feet wouldnt hurt if you plan on a large track.

So the book says 10 feet minimum lane width. I just want it to be a track that isn't too big or too small. something that you would expect to see if you showed up at a place on Race day. Especially if I would consider in the future of letting a local club use it. Or if My kids would decide to race one day then they have something comparable.

I drew up a rough idea and from what I can see scouring the internet, an area of ~120x90 seems to be in the ball park.

what all kinds of obstacles are there?
so far I got:
Bunny Hops
table tops
jumps
banked turns
rumble strips

and Id like to make a X-over, but i'm not so sure that would be seen in a real race

The whole track will be dirt, jumps and all with irrigation pipe barriers. I want it to look nice and last and I may or may not be slightly OCD so I want it done right haha

there is no official limit to design, just your desires/abilities. no, you probably wont find a crossover at a ROAR nationals IFMAR worlds, but many local tracks do have them. it usually consists of one direction jumping over another. look on youtube for track designs. there are also jumps refered to as "singles", "doubles" and "triples". what that means is there are several jumps of the same dimensions in a row and the numerical designation is how many can be jumped at a time. using the first as the take-off point, a single is when the rc lands on the second jump, a double is completely clearing the second and landing on the 3rd and a triple is jumping over the second and third and landing on the fourth.

some tracks also have what are called chicanes. pretty much an abrupt swerve. dont forget about elevation changes. they can take a rather dull track design and transform it into one of the most entertaining tracks ever made.this can be achieved by simply building the track on a hill side or if you dont have any, just dig out part of the track and pile the dirt elsewhere on the track.

just a thought, if you were to extend the length to 150' and build a straight almost as long, you would have a 1/10 scale quarter mile with run-off. the strip would be 132' and a wide banked corner would give sufficient distance for slowing down. when not using it as a strip you could place turn barriers to follow the actual track or build plywood jumps for something like a high-jump competition or for actual racing.

I like the 1/4 mile Idea and I suppose I have the room lol

I definitely want elevation changes, but never thought of it as an obstacle persey, Id love to have a huge pit but I'm concerned with flooding

thanks for the info!!

a down hill hairpin turn makes for one difficult section.

That is probably the most difficult part of any track 1:1 or rc track, yet it's the most fun...

That and a very tight chicane after a 45° blind curve...

my local indoor offroad track is all 4' wide lanes. the track is smallish, no real straights and lots of turns so speeds are kept low (even brushless wont get faster than 30mph)
this technical track is a lot of fun, and the lowish speeds keep bad crashes to a minimum.

with 1/8 scale, id think 8' lanes would be a minimum. if you have the room, no reason you cant do 10' wide.

one thing I knew I would do if I had the space to build a track......id have the inside of the truck basically flat, so that I could change the lane layouts and id have wood ramps that I could move around and change the track.

it takes a lot of work to build a good track. but IMO even the best track will get old after a while. so id want the ability to change the track layout. you don't have to have the whole layout change.....just having a long straight made that you can add/remove a chicane can make a big difference. same with adding a small ramp right before a turn or right before heading onto a long straight.
im jealous....I soo wish I had some land to build on.

the flat track with movable obstacles is a valid point with getting bored of it... but ill see how much work I start putting into it. A bobcat can flatten the hills and move them with ease I'm sure haha I'm sure initially the track will be that way before I build. or I imagine it as such...

what's a good height for a big jump? I'm a basher at heart and I like hills that aren't practical fro racing....

I made a rough sketch of a track I think I'd like. Too bad none of you are closer.... Id have zero issues with help or letting guys run on it

Since you want a customizable track just prepare a nice rectangle all flat, buy or make borders/barriers with corrugated pipe or other flexible material, and use a shovel and wheel barrel to make and move mounds here and there...

I'd reccomend movable jumps to start with, it should help u gauge the distances between the jump and landing.
there is nothing worse than a incorrectly spaced jump, that's when u start bending chassis
