UROC Club Altitude Records

There has been a lot of interest in altitude records between members of UROC. Whether it be for a little "friendly" competition, or an all out battle of the skies.

Club altitude records are established and maintained in order to recognize individuals or groups whose rockets have attained the highest altitudes in club history. They are intended to encourage friendly competition and provide a focus for creative efforts with the ultimate result of furthering the science and hobby of rocketry.

UROC Club Altitude Record Rules:

  • Altitude records may be claimed by any club member or group of people including at least one club member. The member must be in good standing with UROC and with either the NAR or Tripoli at the time of the attempt.
  • The flight must take place at a launch sanctioned by UROC, with the exception of flights taking place at venues with a waiver exceeding that available at UROC venues such as BALLS, XPRS and some LDRS venues.
  • Altitude must be witnessed by at least two other UROC club members.
  • Altitude attempt flights must comply with all applicable NAR and/or Tripoli safety guidelines (depending on whose rules are in effect at the launch), any and all launch site restrictions, and must pass the normal RSO check-in inspection.
  • The launch log or flight card must note the flight as an altitude attempt prior to launch.
  • Single motor, staged, clustered, complex, and boosted dart designs are all acceptable. Records will be maintained for all three categories of motor: Certified, Research, and Hybrid. The rocket component to reach the highest measurable altitude will be used for the purpose of the record.
  • The record class will be based on the total installed impulse of the motor or motors used as determined by the NAR Standards and Testing and/or the Tripoli Motor Testing Committee. For example, a rocket attempting a G altitude record must have at least 80 Nsec and no more than 160 Nsec impulse at the time of launch. This specifically excludes, for example, taking the G altitude record with an F motor.
  • Any rocket used in an altitude record attempt must have a recovery device appropriate for the size and configuration of rocket being flown.
  • The rocket must be recovered in order to qualify - lost rockets are tough luck. Same rules as Tripoli altitude records apply meaning the rocket must be in flyable condition to qualify.
  • Altitudes may be measured using one of the following methods: barometric altimeter, or global positioning system. For barometric altimeter measurements, the unit must be on the list acceptable for Tripoli or NAR altitude records. For GPS-established records, the entire raw GPS data stream must be made available along with the record application.
  • The new record must exceed the previous record by at least 1%.
  • Unless previously claimed, flights prior to October 1, 2000 will be not be eligible for altitude records.

To apply for a UROC Club Altitude Record


Make SURE that you record the altitude of your flight on your flight card post-flight and get your altimeter witnesses to sign or initial the flight card! 

Make sure the card or log entry indicates that this is an altitude record attempts.

and let him know about your attempt. You'll get your name in lights and enshrined perpetually in the altitude record annals of Northern Colorado Rocketry. Make sure you include the following information in your e-mail: Flyer's name, NAR and/or TRA number and cert level, rocket name and description, date flown, motor and delay (if any) used, launch site, name of LCO, method of altitude measurement, measured altitude(s), NCR witness names. GPS raw data file should be included as a text attachment to this email if GPS is used to establish altitude.
Additional information may be requested if the altitude claim is incomplete or is inconsistent with the information provided.
The absence or unavailability of requested information may be cause for denying the claim if the information provided is inconsistent with the claim.
While there is no statute of limitations on applying to claim a record, make your claims expeditiously. Records applied for more than 12 months after the flight will require substantial documentation and be viewed with considerable skepticism due to the difficulty of verifying claims.
Flights that take place at non-NCR venues REQUIRE a copy of the original flight card as well as the signature of the LCO or RSO from that venue as well as 2 or more NCR witnesses.
Flyers will be notified as to the status of their record claim and the results posted on the club web site.
The current NCR club altitude records are located HERE. Tripoli world altitude records are located HERE.

Show off how smart and cool you are by being the first on your block to fly higher than anyone else - Tripoli and NAR records aren't that unreachable...
