There is something local to me that I really want to give a shot, it's going to take a lot of effort so I want some advice before I start to make sure I am not wasting my time, if I start planning now I should be able to do it in November/December if conditions are like last year.
There is a 180yd hill at about 25-30° then a 20yd gap and then a slightly steeper but much smaller hill that smooths out to flat ground.
What size of kicker will I need to clear it safely and is the run in enough?
I won't be attempting it at all unless I am happy with the conditions, lots of fresh to land on and plenty of snow for a good booter.
Sorry for being so vague but I just took a wander over after work today but didn't have a measuring tape. If anyone knows of any sites or even books I could look into they would be much appreciated to plan this, I have a very basic understanding of physics but maths is no problem.
Has anyone on this forum ever done something like this before with taking an idea and theorycrafting it into reality with the aid of science? If so I want to know what you did please. |

| You need to think of run in speed, landing because you dont want to land on the flat and ability. Dont want to sound a dick but would you confidently hit a 20ft kicker in braehead? |

Nope. Doesn't mean I would not try it though under the right circumstances.
The "landing" would be a hill like this with a huge amount of the prep being to clear it with hedge trimmers and weed killer.
[edit]
The measurements and angles are just by looking and pacing, until I can take up a spirit level/protractor/measuring tape etc. |

| I have to agree with Dashie, I hit a 10th kicker in Tignes and shat it, that was with an airbag behind it,took me a further 2 goes to get my freak on, need to make sure your bang on your game or it's going to be an epic fail! That and a good bungee rope for speed, but hey you might be the mutts nuts, good luck with it, |

I have been hitting an airbag, best success with methods off a whippy kicker saw me landing 3/4 of the way down it on my feet, or doing backflips and skiting off the end on my back.
Landing on my feet is not a problem and if I tumble down the bank I have in mind I know it won't be the worst fall I have had so I can deal with it. I figure the best way not to brick it is don't psyche yourself out by looking at it, just have an idea of what you are going to do, then do it - I'm not fearless but I'm not going to hesitate once I start the line in.
Last time I was there however I was told to go fast after they adjusted it and it let out nowhere near enough air and I bounced on the airbag once then 3-4 times off hardpack/ice crud but it's cool because my hip took most of the impact. |

You don't have to have a scientific equation or a calculator to know you would be bat sh*t mental to attempt that jump.
I prefer the term experimental.

Do you know how steep a landing you need for that size jump?
No, which is why I am asking here if it looks doable.

Have you seen how steep the run ins and landings are on park jumps that big?
Yes, but it's hard to fathom them and apply them to what I am planning which is again why I am asking here.
Might go measure it up tomorrow and put on some old clothes to rake about the bracken I will need to shift. |

It's a hill like in the nasty mspaint diagram I drew then a path and some stuff for the gap then a banking then a football pitch on the outskirts of town (fields in one direction hills in another, trees then houses in another).
It's pretty rural with nobody's house facing onto it or anything, would still need to set most of it up when people are sleeping so as not to attract attention then just build the kicker the evening beforehand, let it firm up over night then go back in the morning polish it up and hit it.
I would still like some advice on how to size up the kicker and how to make the landing, if nothing else I would rather put the effort in and decide it's not perfect conditions with a kicker built than try nothing at all. |

Hit snowflex kickers, prefabs, real snow kickers and also some park kickers on holiday but nothing this big. Airbag was a super whippy prefab and last time a real snow kicker. Only built or had a hand in building maybe 5 decent kickers not including ones made from stuff other than snow but none of them were taller than 4 foot and one of them ended up just a bump because the snow was not good for packing into the gradual curve shape. Dropped off plenty of stuff too.
Normally it's just "Build it and see what happens" but I would like some planning for this for obvious reasons. |

| one thing I'd say, other than agreeing that you're gonna have to be fiarly foolhardy to try such a jump, but see if you can steal or borrow lots of those gym mats to put on the knuckle. They may be the only thing that's between going to casualty / the morgue or not... |

Was gonna put all the branches and sh1t that got cleared there since there is no hard wood, cover it with snow or an old mattress is a good idea I guess, cheers for the advice.
Don't get me wrong, I am not doing this to get hurt, got a holiday to look forward to. If there is any doubt in my mind that the conditions are not exactly as I want them for it I won't bother. |
