Ok im not good with math, but a stunt i am thinking of attempting requires alot of it. I need to find out variables such as:

How fast do i need to go?

How high must the jump be?

At what angle must the jump be?

Angle of the landing ramp?

Distance between the two?

How far off the jump (into the air) must i be?

How long do i have?

And so on. Heres the idea. I am going to backflip my four wheeler, i'm dead serious. Before i can build the jump or begin to train, i need to figure these things out.

What i know is the weight of the bike, the weight of me, etc. I dont know what the wind will be, lets assume it calm for now. Can anyone aid me in the math?
