physics of jumping

[doc83]

anyone know the physics behind jumping in a truck?
    how dose the center of mass effect flight charisteristics and why?
    why do trucks tend to go ass over tea kettle?
    and what dose it take to keep a truck levle in mid air?

just curious...

weight bias.

weight in front = nose dive

weight in rear = butt dive

weight in center = good landing

Let off the throttle before end of ramp = nose dive

Keep foot on throttle until airborne= nose high

You need to learn the truck and understand the shape of the ramp your about to hit to decide how much and how long to stay in it!  Well that's if trucks and motorcycles share any of the same flight characteristics and I'm sure the basics are the same.

Those are a few shots of our truck.  The truck is within 40lbs front to rear when it was weighed.  This helps...... a lot of it has to do with how your suspension is set up, the kind of jump you are jumping, and what you do with the throttle when you go off a jump. 

If your suspension transfers a lot of weight to the rear and the rear packs up on the take off you will get that affect of the rear of the truck going over your head.

If the jump has a smooth take off with a long run up to it, you will usually fly better than if the jump is a bit of a kicker.

Then......there is throttle control.  Sometimes you will here someone take their foot off the gas just before going off the jump and then right back on as they go off.  I will do that on certain jumps, especially the kickers to try and transfer the weight of the truck to the rear so the front is light when it hits the jump to fly level. 

So, as for jumping a vehicle there is a lot more to flying level than just where to put the weight on the vehicle.
