St. Augustine Rocketeers is proud to announce its partnership with Discount Rocketry to bring you our first Virtual Rocket Contest!* Using OpenRocket, a free, fully featured model rocket simulator, build a rocket that meets the requirements below and we will have a virtual ‘flying’ contest on January 8, 2021.
- Entry must be (1) OpenRocket ork file
- Name your Rocket
- Contestants may only have (1) entry
- Contestants must register (see form below) to be eligible
- 1% Bonus will be gained on each contest flight if you build, fly and produce pictures of the rocket:
- (1) Picture of the rocket static
- (1) Picture of the rocket launching or descending
- Entries must be received by 1/7/2021
- Contest will take place from 1/8/2021 to 1/10/2021
- 18mm motor, single
- At least two diameters of body tubes for exterior body
- One body tube must be at least 3x the length of the other
- The shortest body tube must be at least 3″ in length
- There must be at least 2 sets of 3 or 4 fins, different shapes and the bottom of the root edge at a different place
- Materials must be standard weights that are in the OpenRocket database
- Materials must be standard thicknesses that are in the OpenRocket database
- Fins can not be any thinner than 1/16″
- Must include realistic recovery and launch lugs (motor hook is optional)
- NO CP Overrides
- NO Mass Overrides
- NO Mass Objects for adjusting weight and CP other than normal required items like shock cord, eye-screws, etc.
- Must have at least 1 caliber of stability with an Estes C6 loaded
- Your rocket will be flown in (3) “contest” conditions events and will accumulate a total score:
- Versatility: your rocket will fly in “contest” conditions with (3) “contest” motors. The conditions and motors will not be disclosed. The placement score for each flight will be the Maximum Altitude (ft) * Rocket Weight (oz)
- Max Altitude: your rocket will fly with a “contest mass override”, “contest conditions”, and a “contest” motor. The placement score will be the Altitude (ft)
- Slow and Low: your rocket will fly in “contest” conditions with (1) “contest” motor. The placement score will be based on highest Time to Apogee (sec) and lowest Altitude (ft)
NOTE: Contest settings and entries will not be disclosed until all entries are in.
Prize Tablewill even throw in free Glue and Wadding for each Rocket Kit with a Discount Rocketry sticker.

StAR #876 Entries (non-competing)
Q. Do I interpret “There must be at least 2 sets of 3 or 4 fins, different shapes and the bottom of the root edge at a different place” to mean the the two fin sets cannot be placed to make a 6-8 fin rocket? In other words, the trailing edges cannot be at the same location?
A. Not exactly, you could have a 6 or 8 finned rocket just as long as the bottom (rear) of the root edge is not in the same spot. For example, 1 fin set even with the bottom and the second fin set (splitting the first set and a different shape) at 0.5″ from the bottom. Or 1 set of fins even with the bottom and another set up by the nose cone.
Q. How does this Bonus thing work?
A. The 1% bonus improves your virtual flights by 1%. For example if you fly to 1540 feet, you will be recorded at 1555 feet. Yes, not much, but we suspect some very close competition and it is geared toward a “virtual” rocket contest, but we wanted to award some that actually built the rocket.
Q. If we submit a design and it doesn’t qualify for some reason, are we allowed to rework the design and resubmit or even submit a new design?
A. Yes, either, both…we will review them and let you know.
Q. What is the measure for the one caliber rocket stability requirement, Barrowman or OpenRocket?
Q. How are Contest Points scored?
A. Each of the 3 events have a “placement score” described. That placement score will then be reversed ranked by the total number of entries. This will give the maximum number of points to the winner in the event. For example, if there are (4) entries and in contest #3 (minimum altitude) and entry #1 gets 800 feet, #2 810 feet, #3 750 feet and #4 950 feet. Then the scores will be 4 points for #3, 3 points for #1, 2 points for #2 and 1 point for #4.
Q. You say materials must be those listed in OpenRocket. Can I build/design any part using those materials?
A. Yes, you may. This does not imply that you have to take the part from the database.
Q. In the events that are described, is the Maximum Altitude the maximum possible, excluding the delay of the motor(s) chosen, or actual predicted, including the delay of the motor(s)? I.e., a design could go 1500 feet on a C6-7 but less on a C6-5 because of early ejection.
A. Including the delay. There are set motors for Events 1, 2, and 3 with set delays.
Q. I didn’t see anything about dual deployment (i.e. drogue chute and main chute). Is that allowed?
A. No, you must use the “Deploy at engine ejection” option
Q. What size and diameter launch rod for the contest?
A. We’ll use OR’s default 36″ long rod, 1/8″ (3.2mm) diameter.
* This contest is modeled after EMRR’s first Virtual Rocket Contest (March 2003).
