Ok i just bought 5 acres and i am wanting to build a track on it.. MX track.. but i dont want it to be some rinky-dink thing.. I want it to be nice.. I have a bobcat and bull dozer.... so building it wont be that hard.. I need a good track geomerty... angle of jumps and how my landings should be angled.. (take-off) (lift) (distance) Its 2 lanes wide in all parts b/c its going to be a fourwheeler only track.. I want big jumps and rithem sections and eveything a pro track would have.. I hope this made sence to everyone who reads this if not just as my to clarify any part.. Any help would be apprecated Im hoping to start the build in about a month or 2

 

I have worked on a few tracks. Since you have a goodsized area, make it fast and smooth, but long jumps it is much nicer than that supercross style meant for bikes. If you are in any type of hills use them to ur advantage as take offs or landings. When constucting the jumps i always use hard clay type dirt as a base and then throw a layer of topsoil on the top, this keeps it a little better from washouts and sometimes ruts. We have got backhoe and dug deep in certain spots to get clay, this makes a good play area for ur 4X4 buddies, then we go to the bush or river flats for topsoil. Latley when building large jumps I make table tops, then I practise on them untill im confidant I can clear them. Then I get the loader and dig out the middle and use it for other jumps so ur left with a nice big double. The only down fall to this is that when other ppl come to use it and there not confidant they roll over them and can wreck the lip of the jump.

 

This is how I like my jumps. STEEP!!

If I had a bob cat I would make a huge 5th gear table top. Me and my friend were trying to make a huge table top with a bob cat but the bank too kit away befoer we could get dune. We were going to build it all summer long to make it huge but we onlh had it for 5 days [img]i/expressions/face-icon-small-frown.gif[/img]

 

I like big smooth jumps.... but my main concern is angle and lift.. Like if u have a 45 degree jump how far will you go? how much lift will you get?? and what should the proper landing be? I have been trying to get intouch with some track designers but no luck yet i will keep trying though

 

When im building I do not use any angles and mathimatical figures, just build them and get used to how different slopes effect the jumping and reshape them till ur comfortable. yz426ex that jump is scaring me just looking at it! It is steep and narrow for a quad, hope u have a nice landing.

 

Its 5ft wide just have to make sure you keep the bars streight. Right after that jump it goes all down hill. You only have to jump 40ft and you still land on teh landing spot but I usualy over jump it just for extra air cause just 1st gear and you hit 15ft of air. That jump made me break a axle, bend my a-arms up, bent rims, broke a raptors frame and shock mount. But izz fun [img]i/expressions/face-icon-small-shocked.gif[/img]

My friends brother made a 10 ft tall jump and the landing was 1ft tall cause hes retarted. Well he hit it and as soon as he landed fliped. Then a nother retard tried it and flipped so it was turnt int a big berm.
