Here's the side-view plan for the blue ramp. Sorry, I guess the exit angle was "only" 70 degrees. All dimensions are either in feet or degrees. I built it four feet wide to make cutting the plywood simple. After the CADD drawing is a shot showing the construction and bracing. The sides are 3/4" plywood, the cross pieces and framework are all 2x4s, and the ramp's surface is 3-ply 3/8" plywood for easy bending.

As for bending the plywood to make the ramp surface, how did you do that? did you have to thoroughly soak the wood in water to get it to bend? If you care to divulge that secret, please do so!

Yes you do! 
The DVD is [link=http://www.smfstore.com/index.php?cPath=75&osCsid=6096m9e95h4ljfli0cvmqbbeh3]only $10[/link] right now, too.
SAVAGEJIM, bending the plywood is easy because it's only 3-plies thick. Two plies have the grain going lengthwise, the middle has it going the other way. Bend in the direction opposite the grain of the outer plies. Get to a Home Depot or something and try it, you'll see what I mean. The only unfortunate part is the 4'x8' sheets all have the grain of outer plies going lengthwise, so you have to cut the sheet into 4'x4' squares and rotate them 90 degrees to put them on the ramp surface so they're bendable. The reason for the odd horizontal and vertical dimensions of the blue ramp are so the ramp surface itself is 8' long in order to use one entire piece of 4'x8'x3/8" plywood.
I've got more details of that ramp and a few other other ramps available. I'm working up a page about ramps right now and I'll list as much info and show as many pics as I can.

That would be great! If you can, start a new thread on your build up with all the detailed instructions and procedures to construct it!

LOL WOW!! I can see why you had so much air that things on a giant hill. How much damage did it do when it landed?

Those downhill ski ramps exit at a DOWNWARD angle, not an upward angle. The skiers rely on their skis and bodies to "float" through the air for the maximum amount of time (and therefore distance), but since the ramp exits downward and about 40-50 feet out from the end of the ramp the ground drops away, they're never very far off the ground. The go so far because the hill is so darn steep! They're falling the entire time, but the ground is "falling" as well.
Anyway, due to the fact that the ground doesn't fall away for 40-50 feet and that the ramp's surface was pretty much solid, rough ice (no traction) we were never able to get enough speed to make it in the air past that lip where the slope steepened, even after adding a kicker ramp at the bottom of the ski ramp. Thus, we kept landing at the lip, bouncing, and then cartwheeling for a couple-hundred feet down the slope.
Even after all that, my Savage only popped a tie rod end off the pivot ball, my buddy's Savage had very minor damage (don't remember what, but he was driving it again after a five-minute fix), and my GS Storm buggy (pictured in this thread with the pancaking MT tires) broke a front lower arm. A few vehicles didn't even get that far due to the ice, like my NMT, a couple RC10GTs, a CEN Genesis, and a Schumacher Menace.
We filmed it all, but it's only on our DVD, not on our website.

RE: massive jumps on a beautiful day
man these single brand loyalty people are missing the whole picture, there are a lot of nice vehicles out there, and they're not all made by the one company, the LST2 is a great truck, the savage is, and the revo is, the X ray XT8 is a good truggy, as is the mugen and losi 8ight T, if you keep this single brand loyality you'll have a great time bashing owners of other trucks, and miss out on a heap of fun driving them, each has it's strong and weak points, and none are perfect.
