Yes, as long as the tape is easily removable and does not impact other subsequent teams' testing.
Yes, as long as the holes are filled with a fastener used to attach a blade. No holes or slots may be used for the purpose of reducing the mass of the CD.
(section: 3 / paragraph: b / line: 2)
No, this would not be a modification of the CD. Light sanding to create a rough surface for gluing purposes only where the blade is mounted is fine. Sanding the whole CD is not allowed. The local event supervisor will determine if a modification has been made to the CD.
(section: 3 / paragraph: f / line: 1-2)
The limitation is only for the side of the CD that is facing the motor/generator.

(section: 4 / paragraph: G / line: 2)
Yes, see 4.f. They may push the blades by hand to initially get them spinning but they may not touch the blade assembly during the measurement period.

Correct, if teams choose to use the max 80cm size, they are then limited in the orientations they may place the device in. Smaller devices will have more possible orientations available.
(section: 3 / paragraph: e / line: 2)
No, the triggering device separates itself from the launch device. Any parts remaining that are attached to the launching device after a shot are considered part of the launching device and must follow Rule 4c.

(section: 4 / paragraph: f / line: 1)
Yes, lasers may be used as a tool for setup, adjustment, & calibration of the device. They must be removed prior to launch. The laser policy posted on the National website must be followed.
(section: 4 / paragraph: h / line: 1)
A rope can be considered a calibration tool as long as it is removed from the device during each launch.
(section: 4 / paragraph: i / line: 1)
