From what I have figured out on my own, I set the foot rest just a bit lower than the pedal. The right side of your right foot rests on the footrest and the ball of your foot rotates downward.... Pretty much you twist your foot to go faster. I have been tempted to screw an old hasp from a pad lock set up onto the steel floor with the long part of the hasp on top of the spoon gas pedal. This would very simply convert the foot twist pedal to a normal pedal like we have all known and used with the off brand products. Perhaps I am missing something important here. It wouldn't be the first time.
