RE: vids
hehe... i saw a vid clip of someone doing a backflip on a snowmobile... i guess he saw the x games and said "if those punk motocross guys can do it....."
but yeah... its all in the throttle... but you gotta get a feel for how you particular truck/buggy/whatever reacts... some times a little too much will send you inverted without enough room to correct.
and tires play a big part in this... if you change tires its going to change the rotating mass and the handling in the air. so take a few small practice jumps before you try the big ones.
