Me and a few friends are building a new spot with some jumps and a drop as our old spot got torn down. Our first jump has a 35 foot gap. it is a small step down. The landing and jump are on a slope so I was able to hit it without a landing and figure out where our landing would go. Today we finished building the takeoff for the jump after the 35 footer. I am not sure where our landing is going to go. I dont want to hit it without a landing because it is flat. Besides eyeballing it are there any other ways to figure out where to put the landing. And landing to flat also isnt very accurate because we will have a decent sized landing and I will have to subtract more distance as the landing gets higher. After hitting the first jump the one we just built comes up on us very quickly since we're hauling ass for the first jump and landing on a slope.



Thanks for your help everyone. I will be doing a lot of building during winter break so expect pics.

build a table....or just build the landing closer and then keep extending it out further

35 feet is a BIG gap

By small I meant how many feet you descend when you do the step down. I really would like to get it right the first time because its going to have a big landing so moving it and packing it in again would be LOTS of work.

Use physics to get a rough idea

depends on how fast you are going.....if you go fast then the landing is further out....slower the landing is closer....if you have to move a huge mound to get it right then that is what you will have to do....it sucks but that is the way

ahhh...but not w/ a bobcat:thumbsup:

thats physics for ya.

I just thought of something. I could have my friend hit the first jump and as he passes by me I will roll a ball right next to him . I could do that a few times and try to keep the ball rolling at the same speed as him. I would then roll the ball at the landing at the same speed I rolled it to make it keep up with my buddy.

Wayyyy to much work. Just build it huge, step up to it, and then you won't have to move it. Always build bigger than what you are comfortable with, it's what pushes you.

And don't be afraid to move some dirt around once or twice

Im not afraid to move some dirt around. Im actually the one that wants everything perfect out of all my friends. I already moved the landing for the 35 footer and made it bigger. I am not lazy.
Rolling a ball a few times is not much work. Moving a giant landing and packing it in again is a lot more work.

Its not only moving the landing, I want to avoid eating sh.it

Get a bike computer, mount it and record the speed of the bike as it approaches the jump. Now just measure the angle of the lip and input everything in the formulas you learned in high school physics. It WILL give you a rough, but very good, idea of where to put the landing.

If you're truly a MTB_prodigy like your screen name says, you should know the answer to your question already.

 

[ronnyg801]

Is it just me or should dudes that can hit 35 foot gaps be able figure out by look and feel where a fair placement for a landing should be?

 

[NorKal]

build a table

Have you ever built a 35 foot table? I mean seriously, have you ever moved that much dirt for one jump?

 

[dusthuffer]

The one I'm most familiar with is:

v=d*(sqr(g/((2*Cos(a))*(d*SIN(a)-h*cos(a)))))

Where:
v = speed at launch (fps)
g = 32.2 (gravity constant - acceleration rate of ft/sec/sec)
d = throw distance (ft) = x
a = launch angle (degrees) = 45
h = height of landing point relative to point of impact = -1

1. No, I didn't come up with that myself.
2. Figure out your fps etc. and so on.
3. Solve for X.

A lot of you guys probably think that the 35 foot gap is huge but it really isnt. The bottom of my wheels are only about 7 feet high at the highest point while in midair.

yeah, that was my point exactly. Especially if you call yourself a "prodigy"

For me the run in usually dictates where the landing will go. It is usually not so fluid if you have to drag the brakes on a jump because judging speed is hard. I tend to build a corner or a hip before a jump to get the speed just right. That usually means that you have to hit a corner flat out to hit the jump. That way you know what kind of speed you have to have going into a couple features before the big move.

 

[trail bait]

I would just hit it to flat and figure out the landing from there, that's what shocks are for. With distance speed is your friend go fast it's smoother when flat landing. Good luck with that, and keep us posted.
