Instructions
Approach a ramp at high speed by holding down the "1" button.
Hold "B." As you go up the ramp, hold the "Up Arrow." At the top of the ramp, move from the "Up Arrow" to the "Down Arrow." This starts the backflip.
Hold "B" and press either the "Left," "Up" or "Down" arrow to perform a move during the backflip.
Release the "B" button and use the arrow keys to safely guide your vehicle to the ground.
