No. Vehicles are not allowed to start on ramps and the vehicle cannot be the falling mass. If the wheels are not touching the floor in the “ready to run” configuration then they would not be allowed to touch the floor after the run has begun since it would be in violation of the rules (see FAQ posted on 12/22/13).
Only the wheels of the Scrambler and any parts of the Scrambler in contact with the floor at the ready to run configuration are allowed to contact the floor. If any piece falls off the Scrambler during the run, it is a construction violation. Therefore the falling mass cannot touch the ground at any time.
Yes and no. The tape for the start line - correct. The other tapes are really up to the event supervisor as long as timing begins exactly 0.2 m from the start line and ends 8.2 m away from the start line. The Event Supervisor will let the team members know which edge of the tape correspond to each of the lines specified in the rules.
Finally, yes the inside edge of the side tape should defined the track width.
