First, go to consruction mode, then just press play,next get a speedy car,ok now listen carefully....when you first start out of the right edge of that building you know those dirt hills you drive off of? Ok next align your car to the biggest dirt ramp there(second one) then go as fast as possible! And try to aim and the very very tippy edge of the right side of the ramp!! But becareful don't aim too high or too low otherwise this wont work!!!! You'll do sick flips and get awesome air!
