SLRA will hold a rocket launch this coming Sunday, April 28th at Buder Park. The current Weather Underground forecast for Valley Park predicts partly cloudy skies and winds under 10mph, with a temperature of 44F at 9:00am rising into the mid 50s in the afternoon. Bundle up!
As always, please check the website for last-minute updates before heading to the field, or check your email if you are subscribed to the email list.
We'll start setup at 9:00 am and should have the range open by 9:30 if not earlier.
The launch has been sanctioned as an NRC competition launch; please talk to John Buckley (firstname.lastname@example.org) if you want to do any competition flights.
If you have any questions, please email email@example.com.
(The fine print...)
Launch pads are usually set up in the southeast corner of the park, but this may change based on wind direction and other activities nearby.
Anyone who is a current, paid member of the National Association of Rocketry or Tripoli Rocketry Association is welcome to participate. Due to insurance regulations, those who are not a member of one of the two national organizations will need to have a NAR or Tripoli member inspect and fly their rockets for them. Non-members will also be asked to sign a liability release. If you wish to fly your own rockets, please be prepared to show your NAR or Tripoli membership card, or a receipt of payment if you are a new member who has not yet received a card.
Please note that these launches may be cancelled for a number of reasons, notably: weather conditions (rain, high wind), park conditions (mud, flooding), or scheduling conflicts (another group’s use of the park makes it impossible to safely launch, or not enough SLRA members are available to run the launch). Please check the “current launch status” on the front page of our website, http://stlouisrocketry.com, before making your way to the park. Also, the number of people in attendance has a bearing on how long the range stays open; if you plan to arrive after 11:00 am, please call ahead (314-630-7619) to make sure we’re still flying. We will continue to fly rockets past noon if the weather is good, our battery holds out, and people still have rockets to fly.
Buder Park launches are conducted under the NAR safety code as “Class 1” rocket launches. Class 1 launches carry the following restrictions:
- Rockets must weigh less than 1.5 kilograms (3.3 pounds) at liftoff, including propellant.
- Rockets must contain no more than 125 grams (4.4 ounces) of propellant – this includes most motors up through G class (although see the note below regarding high-altitude launches). Only certified, commercial motors are allowed.
- Rockets must be made of wood, paper, or breakable plastic, and contain no substantial metal parts.
- Rockets must employ a recovery system such as a parachute, streamer, helicopter, glide, tumble or featherweight recovery
- Decisions of the LCO (launch control officer) and RSO (range safety officer) are final with respect to these restrictions and safety in general. Our goal is safety for everyone involved.
The total size of Buder Park is approximately 2100 x 1200 feet, which according to the Model Rocket Safety Code is large enough to fly a G motor rocket. However, please keep in mind that we are usually not the only users of the park – we share it with radio control aircraft flyers, archers, sports teams, joggers, and many others. Also, the perimeter of the park is lined with very tall trees, and just beyond the north treeline you will find the Meramec River. Have some idea of how high your rocket is expected to go before you launch, keep the wind conditions in mind, and use common sense. Experienced SLRA members will be happy to advise you to make sure your rocket is safe and likely to be recoverable.
