Walnut Grove, MO
Launch will be a combined effort (High Power, Virtual NARAM 2020, and NRC contest) of St Louis Rocketry Association (St. Louis) and Tripoli MO-KAN (Walnut Grove MO). The event will be held on the site of NARAM 58 in Walnut Grove MO, July 18-19, 2020. Site location is at - 37.4486N, 93.61565W.
John Buckley will host a model rocket competition range sanctioned under NRC rules.
Gary Cole will host the Sport Range. On the sport range rockets up to and including M impulse class may be flown. The maximum permitted altitude will be 12,500 feet AGL. Rockets projected to go over 8,000 ft, require a simulation prior to flight. Also, if you plan to conduct a Level II certification flight or have any questions regarding the sport range operation, please contact Gary Cole at Gary Cole is Range Safety Officer over all aspects of the launch including contest. Currently there is no local attendance limit in effect. However, we will follow current local and state health department guidelines as follows.
General Guidelines for Missourians
• Citizens who feel sick should stay home!
• Continue to practice good hygiene, including:
o Washing hands with soap and water, or using hand sanitizer, especially after touching frequently used items or surfaces;
o Avoiding touching your face;
o Sneezing or coughing into a tissue, or the inside of your elbow; and
o Disinfecting frequently used items and surfaces as much as possible.
• Avoid socializing in groups that do not readily allow for appropriate physical distancing. When in public (parks, outdoor recreation spaces, shopping malls, etc.), individuals should maximize physical distance from others.

Accordingly, we will do the following:

(1) Have hand sanitizer at several locations at the field
(2) Will not provide pens or pencils for common use to fill out flight cards - please bring your own
(3) Will not permit congregating at the LCO table or other areas on the flight range and LCO activities will be conducted in shifts, permitting sanitizing the launch controllers, PA system, etc.
(4) Will not operate model rocket racks due to lack of proper distance - rather, we will have discrete pads for the model rocket flights
(5) Encourage everyone to be mindful of maintaining appropriate safe distances
We recommend checking in advance the status of the launch before attending.
Range hours will be approximately 12 PM to 6PM Saturday and 10AM – 4PM Sunday. These hours are approximate subject to weather conditions and range safety officer’s discretion. Contest hours may be extended or shortened at the Contest director’s discretion (John Buckley).
A block of hotel rooms in Springfield has not been planned as yet, but may be if there is sufficient interest.
We will host a model rocket competition sanctioned under NRC rules. The Heavy Metal V contest will consist of the 6 events of the 2019/2020 NRC events list plus the three additional Virtual NARAM events. Contestants are free to fly any or all or none of the NRC events. Results for these events will be submitted to the national scoreboard. We will not provide payloads or altimeters. NO returns are required for this event except as required by the sporting code for altitude events.
Flight cards and contest paperwork will be available. NRC flight data will be submitted by the CD but Virtual NARAM flight data must be documented on the virtual NARAM website by the contestant. Virtual NARAM events that are also NRC events must be conducted under Sporting code rules. No returns required; actual durations will be used for the virtual scores. Virtual NARAM events that are flown will count toward the meet championship.
Contest hours will be 12PM (setup time) to 6PM Saturday. Contest flights will begin sometime after that. Sunday will begin at 8AM and the contest will end promptly at 3PM. These are approximate and subject to weather conditions and the contest director’s (John Buckley, ) discretion. Sport range hours may differ slightly.
For flying of drones and radio control aircraft anyone operating a drone must be a member in good standing with the AMA (they will need to show us their card). Anyone flying off the sport or contest range must be either a NAR or TRA member. Nonmember guests will need to have a TRA member take responsibility for their flights.

Buder Park model rocket launch, Saturday June 27th

This is just a reminder that our next model rocket launch at Buder Park is coming up next weekend and there are still a couple of spots remaining. (We are still requiring pre-registration for our launch due to St. Louis County COVID-19 guidelines; see the previous posts here and here.)

The weather forecast indicates a chance we'll be rained out, but we'll continue to watch that and make a go / no-go decision later in the week as we usually do. If the launch is cancelled due to weather, I'll contact everyone who is registered and ask if you want to carry your registrations over to the next launch scheduled for Sunday, August 2nd.

June 27th launch – small correction

One small correction to the previous announcement: per County guidelines, any kids over the age of two count towards our limit of ten participants. So please disregard the point about a parent and child only counting as one registration spot - when you register, please let me know the total number of people (including children) you're registering for.

Also, please remember to let me know in your email whether you're a paid NAR or Tripoli member (include your member number) and whether you're a paid SLRA member.

Buder Park Model Rocket Launch – Saturday, June 27 – READ SPECIAL RULES BELOW

Our next model rocket launch is scheduled for Saturday, June 27 at Buder Park - under SPECIAL RULES due to the Coronavirus Pandemic - read and understand below.

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 8:30 am and should have the range open by 9:00 am. The range will stay open for as long as people are flying, but we're typically done by 12:00 or 1:00 pm.

If you have any questions, please email


In order to comply with the latest guidelines issued by the St. Louis County Department of Public Health (DPH), SLRA’s Buder Park rocket launches will be limited to a maximum of ten people (two officers and eight flyers). Additionally, SLRA will not be able to host students, scouts, or any other groups at our park launches until social distancing is lifted. Here’s how we’re going to manage that:

  1. Prior to each launch, each person who wants to attend must register by emailing Dan Crank at If you are a NAR member, please include a scan or photo of your NAR card with your first registration email (I will keep these on file until they expire). If you are not a NAR member, I will send you instructions for signing a liability release electronically.
  2. Slots will generally be assigned to people first come first serve, but…
  3. To ensure as many people as possible get to fly, priority will be given to people who registered for a previous launch but did not get a slot, and people who did not register for the previous launch. For example: Bart registers for the May launch, gets a slot, and attends. Lisa registered for the May launch, but did not get to attend because Bart got the last slot. Maggie did not register for the May launch at all. If all three register for the June launch, Lisa has first priority for a slot, then Maggie, then Bart (regardless of when they sent their registrations). Then, if Bart doesn’t get to fly in June, he goes to the top of the list for July.
  4. Lists will be finalized 48 hours before the launch and everyone who sent a registration will be notified by email whether or not they got a slot. If there is a no-go for weather, flooding or any other reason, it will also be decided 48 hours before the launch if at all possible.
  5. Any kids over the age of two count towards our limit of ten participants
  6. People slotted as officers will get to fly rockets, but will be expected to help as LCO (launch control officer) and / or RSO (range safety officer) for a portion of the launch. SLRA club officers and people whose names are on our GSLMA permits can act as launch officers; others may be deputized at the discretion of an officer. There will be no badges (although Don will try to sell you a name tag).
  7. As with everywhere else, DPH-issued social distancing guidelines will be in effect at all times during the launch. Specifically for us, this means:
    1. While at the launch pads or flight line or anywhere else, maintain a distance of six or more feet from anyone who is not a member of your household. Please approach the launch pad one at a time to rack your rockets.
    2. Only the LCO should be at the launch control table (there will be no sign-up sheet as we’ve had in the past).
    3. RSO inspection of rockets, when necessary, will be “hands-off” at a distance of six or more feet.
    4. Please bring a mask (a bandana is OK) and wear it while in the vicinity of the flight line or launch pads, unless wearing a mask would compromise your health (let me know if this is the case). If you’re by yourself in your prep area, or out in the field retrieving a rocket, you are not required to keep your mask on (although you can if you wish).
  8. It goes without saying that all rules of the NAR Safety Code remain in effect.
  9. If you have any questions or concerns about these rules, please email Dan Crank at This is a new situation for all of us, and we’re figuring it out as we go. If you have ideas about how to make the launch better (“better” being defined as safer, fairer and more fun - in that order), please bring them up for discussion with the club.

Updated St. Louis County DPH guidelines effective May 18:

St. Louis County Parks and Recreation page, with park-specific information:

--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,, before making your way to the park.

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.

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.Posted in Mail_All_UsersUncategorized | Leave a replyPosted in Mail_All_Users | Leave a reply
