Attendance at events hosted by the Rocketry Organization of California (ROC) is AT YOUR OWN RISK. Membership in the National Association of Rocketry or the Tripoli Rocketry Association includes insurance as a benefit. ROC membership allows you to fly at our launches without paying the daily launch fee; ROC membership neither provides insurance nor implies any assumption of liability.

Click for ROC Flyers’ Responsibilities

  • ROC is a volunteer organization, so we appreciate help with setting up and taking down the launch equipment.
  • We start setting up for single-day monthly launches around 7 AM.
  • Setup begins for multi-day launches (ROCStock and special events) on the days before the launch.
  • All attendees must check in at REGISTRATION and sign the ROC Agreement and Liability Release Form. We’ll give you a wristband to indicate that you’ve checked in. Spectating is free; launch fees for flyers are listed on the fee schedule.
  • ROC supplies launch pads and a centrally-controlled launch system. We have launch rods for 1/8″, 3/16″, and 1/4″ launch lugs, and launch rails for 1010 (1/4″) and 1515 (5/16″) guides. Rails are highly encouraged for rockets G powered and above, with a limited amount of rods available at the mid and away pad banks.
  • We have porta-potties on site. Please do not throw trash in them.
  • Our FAA waiver is to 7,000′ AGL.
  • We fly under the safety codes of the Tripoli Rocketry Association (TRA) and the National Association of Rocketry (NAR). Hobby rocketry is also regulated in California by the Office of the State Fire Marshal (OSFM).
      • All high power flights must be conducted by users certified by TRA or NAR. For information on certification, visit the TRA or NAR websites.
      • All motors must be listed by the OSFM as “model rocket motor” or “high power rocket motor. Evidence of this is an OSFM stamp on the motor, packaging, or accompanying paperwork.
      • High Power Rocket Motors must be used by, or under the guidance of an OSFM Pyrotechnic Operator. For more information, consult the OSFM website.
      • California regulations limit the maximum single motor size to M (10,240 Ns).
      •  The size of our launch site limits the maximum complex total impulse to M (10,240 Ns).
      • If you plan on flying a cluster with an impulse over 5120 Ns, please contact us ahead of time so we can have a pad at the appropriate distance.
