The TARC rules for 2019-2020 have been announced (see www.rocketcontest.org). Major requirements include:

• Rocket must carry one egg.
• Target altitude for qualification is 800 feet.
• Target duration is 40-43 seconds.
• Rocket length must be 650 mm (25.6”) or greater.
• No requirements on body tube diameter.
• Rocket mass at liftoff (including motor) must be 650 grams (22.9 ounces) or less.
• Motor maximum total impulse = 80 N-sec (F motor).

Safe operations are our top priority at Fiesta Island. Requirements for flying TARC models at Fiesta Island include:

• Rail launch (6’ or longer) or other rigid launch guidance is required. 1/4″ launch rods are not acceptable.
• Positive motor retention is required. Taping motors or friction fit is not allowed. [Note: this is already a TARC requirement, and we will enforce this requirement.]
• Minimum average thrust of motor = 30 N. Use of low thrust motors such as Estes F15 is not permitted.
• Minimum stability margin of 1.5 diameters required. Inadequate fin size can lead to roll-yaw coupling that adversely affects performance and trajectory.
• Fabric parachutes for strength. Plastic “garbage bag” parachutes are not permitted.
• Simulation report (Rocksim, OpenRocket, or similar) should be presented documenting mass, CG, CP, max altitude, and time to apogee (i.e., make sure motor has appropriate delay).
• Safety check – demonstrate motor retention, shock cord attachment/strength, etc.
