Location: Buder Park North
SLRA will hold a monthly model rocket launch at Buder Park from April through September. Come out and fly those rockets you’ve been building all winter! Spectators are also welcome, but are not allowed to approach the launch pads.
The exact location of the launch pads will depend on which way the wind is blowing and what parts of the park are already in use when we get there. Please drive around the perimeter road until you see the launch rack (it looks like a big sawhorse).
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://dmortproductions.com/stlrocketry, 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 on a Saturday – 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.
Finally, please remember to take adequate precautions in hot weather – use sunscreen and bring water or sports drinks to stay hydrated. One nice thing about Buder Park is that there is plenty of shade around the edges of the field, so please take shelter from the sun when you need to.
