The Arkansas Rocket Challenge 2011 Competition Rules

1.  This competition will not use altimeters. This competition will instead be a B6-4 engine streamer event. No
parachutes will be allowed. The competition winner will be the rocket that has the longest flight time measured in
seconds.  The time will be determined by finding the average of three independent timers.

2.  This event will consist of two rounds of competition.  After the first round, the top five scoring times will qualify
for round two.  To qualify for the second round, a team’s rocket must have a top five qualifying time and be
flight worthy.  There could be more than five teams qualifying for the second round due to ties in flight times.  All
top five times will compete in the second round.

3. In the event there is a tie for first, second, or third place after two rounds, the mass of the rocket will be used
to break the tie for that place.  If a heavier rocket can perform the same flight time as a rocket of lesser mass,
the heavier rocket would win the tie breaker.    Mass of the rocket will be used after round two only to break any
ties and determine the award of the trophy.      

4.  If a rocket is unable to safely make a second flight, that team is disqualified for round two.  No replacement
rockets will be allowed and no additional teams will be allowed to enter the second round to compensate for the
non-qualifying team.  (For example, if two qualifying rockets cannot compete in round two due to damage, then
the second round will consist of two less launches).   

5.  At the moment of launch initiation a stopwatch will be started.  The stopwatch will be stopped when the rocket
model part with the streamer attached makes contact with the ground.  Three stopwatches will be used, with the
official flight time being an average of the three recorded times measured to the nearest 1/10 of a second.

6.  If a stopwatch malfunction occurs, then the official time will be an average of two recorded times.  The launch
director has the final authority on all flight times and can request an additional launch be made as deemed
necessary and may use a backup stopwatch as he deems required.

7.  First, second, and third place teams will be awarded team trophies.  Trophies will also be awarded for the
most "photogenic rocket", the "wildest ride", and the best “ school/group team spirit”.  All students will receive a
certificate of participation awarded by their respective sponsors.

8. The launch director will be the final authority concerning measured flight times, safety, and all other issues
related to the competition.  The launch director has the authority to mitigate any question in competition results
to ensure a fair and fun event for all competitors.  

9.  A team is comprised of one rocket and any number of middle, junior high, or high school age students that
have designed a rocket for launch.  Teams must be sponsored by a teacher or group sponsor.

10.  Each adult sponsor can have up to five teams, but only one rocket per team will be permitted.  Home school
associations, Civil Air Patrol Squadrons/Flights, and scout groups are all eligible.
11. Each model rocket must be powered by a single Estes B6-4 engine.  Engines of different sizes or delay
times will not be allowed.

12. The model rocket can be built from a kit.  Kits and supplies are readily available at hobby stores or on-line.  
(see the
Tips & Tricks page on this website)

13. Models can be homemade, but must be constructed from supplies designed for model rockets.  For
example, cardboard body tubes, balsa fins, plastic nose cones, and shock cords sold for model rocketry should
be used.  There is no restriction on body tube diameter, but no “scratch built” rockets will be allowed for safety
reasons.  “Scratch built” refers to rockets designed from non-traditional model rocket parts and supplies, i.e.
paper towel cardboard rolls, pvc, glass, metal tubing, etc..

14. The model rocket must have a plastic or Mylar streamer installed on a shock cord between the body tube
and nose cone that freely ejects from the body tube when the ejection charge fires at the end of powered flight.  
There is no restriction on the number or size of the streamers.

15. The model rocket must have a launch lug attached to the side of the rocket.  All standard sizes (1/8, 3/16,
and 1/4 inch) launch lugs are acceptable.  Launch rods of these sizes will be available for use on competition

16. Teams arriving late to the launch site due to unforeseen circumstances can still compete provided the last
team present at the competition has not launched their rocket during the first round.  After the last rocket
launch is completed, winners of the competition will be determined.

17. Teams that fail to launch their rocket due to an engine misfire resulting in the rocket not leaving the launch
pad are allowed to reconfigure the model.  Once the rocket has left the launch pad, a successful launch will be
considered to have taken place and the recorded flight time will be the official competition score.

18. There is no need to bring your own launch equipment.  All rockets will be launched from competition
supplied pads using engines supplied by the launch director.

19. Team members are required to wear impact resistant safety glasses with side shields during the loading and
firing of their rocket.  

20. Last minute repairs before the first launch attempt will be allowed provided those repairs can be made
before the last rocket is launched.  All others will be disqualified.  No modifications or design changes will be
allowed at the launch site.

21. All model rockets will be inspected for flight worthiness prior to launch by the launch director. Teams will be
allowed to make changes to their models to meet launch director concerns provided those changes can be
made before the end of the competition.  This is required for safety.

22.  All National Association of Rocketry safety rules will be followed and insisted upon. Read the
NAR Safety

23.  Team names are encouraged.  Naming your rocket is fun!   Wearing a team t-shirt or school colors makes
you look cool and will help you win the spirit award.
