So as we know, what Tom did during the encore was amazing, but it was a successful double backflip. I believe Tom won't stop until he gets it perfect. What do you guys think. This is what I think: The stunt truck needs to be a rear engine truck. The reason is to make the rear rotate as fast as possible. Take a half filled water bottle as an example, turn the bottle upside down and try to flip it from the bottom of the bottle, now put it right side up and try to flip it from the cap, more rotation and faster, same concept needs to be thought with the stunt truck.
