    Wear a hat the covers the neck. Wear long pants. Cover any exposed skin even ear lobes with sun block with SPF 40 twice a day.

    Wear an old pair of shoes on the Salt Flats and carry an extra pair of shoes in the car. When you get to the hotel parking lot, take off the old shoes and put on the other pair.

    Ahhhhhhh,
    One ought to remember that GPS trackers have an edge out on the playa and plan accordingly. The Ham radio stuff on the 2 meter and 70cm band definitely has a range edge on the lower powered 900Mhz stuff but the key is getting that “last known” position just before the rocket hits. That’s where a good antenna system and if necessary, a higher powered tracker comes in. I’ve been told that out on the salt flats, once down on the playa, the salts soaks up Rf energy like a sponge so the “ground footprint” of a tracker is ridiculously small. Been told GMRS/FRS voice walkie talkies don’t carry very far. Guys have emailed me that they had a b!tch of a time trying to get an RDF fix using that method out there with really extreme flights and came close to and sometimes did lose a rocket using that modality.
    One wants to get that last GPS fix as close to the ground/landing site as possible. They can miss every fix through the flight but if they get that “one last fix” before the rocket hits/touches down, they’ll get it back.
    My experience is if using a 100mW, 900Mhz tracker, then a minimum diameter J powered project that lands 2 miles away is easily found in a Midwestern site.
    Out on the playa with no obstruction to effect in air range (unless the rocket goes behind a mountain!), the in air reception might be even better but on the ground, the ground footprint is really short if lying on the salt flats. Plan accordingly. A Ham Technician license is easily obtainable if one wants to experiment on those bands.
    Have fun. Kurt

    Fortunately, any rocket painted other than white is very easy to see from quite a distance on the salt flats.

    I’ll definitely be playing with my 70cm 100 mW beacon (no GPS). On the Flats, I’m mostly worried about getting a compass bearing before landing. Then it’s just a nice hot hike.

    +1 on the hat with neck/ear protection! And on the long pants. I have heard that if you are wearing shorts/skirts/kilts that are loose, you can get sunburned underneath from the sun reflecting off of the salt into areas where you did not apply sunscreen.

    I also usually wear long-sleeve hiking shirts - the loose, breathable, sweat-wicking kind. Protects better than sunscreen. (Me at Grand Canyon, not a launch, but you get the idea.) It ain't pretty, but some of us have just given up on appearances anyway.

    IMG_1374.JPG

    I apply SPF 50 every 1.5-2 hours. I also try to ensure that I drink 16-32 oz of water or Gatorade during the same time period. I use the shift changes at the RSO table as my time markers.


    Why has it been 5 years before I hear about the shoe trick? <Bangs head on desk>


    One of the things that I really like about the salt is that we can drive to pick up our rockets. Not permitted at our usual launch site. Definitely a benefit.

    I like the two pair of shoes idea, but I change mine when I get into the car. It helps to keep the salt out of the car.

    Being a desert rat for most of my life, covering up is standard practice. Sharon and I both take the extra steps to be safe out on the salt. At the 2015 Hellfire, I flew my 54mm MD Blackhawk on a CTI L640 dual thrust to 22,535 ft.
    [​IMG]

    Won a trophy at the banquet for highest flight. It took quite a while to find it, despite the Eggfinder and CSI tracker beacon. GPS lost lock on boost, and the CSI beacon was weak and unreliable. Still found it, black rocket on the salt is easy to see, once you get close enough.

    Here's Sharon with her "Jimbo Jart", well protected from the sun, with sun gloves and a hydration pack ready for recovery.

    [​IMG]

    One thing that didn't work was the plastic tarp, much better to get a RV patio mat, like the one in the background here:
    [​IMG]

    The tarp just collects salt, but the woven mat lets it fall through, and you can keep it cleaner. It also works well to remove salt from your shoes.
    Another thing to remember is that EVERYTHING exposed to salt will corrode. I washed under the truck and spend several dollars at the self serve car wash cleaning, and still found piles of salt on the driveway weeks later. The little trailer had massive rust all over it, even after washing it. Galvanized tent posts rusted. Our old 98 GMC truck will never be the same. Don't take anything made of metal out there if you want to keep it in good shape.

    I drive away from the Salt flats with one set of wheels on the rumble strip and then the other before I wash underneath. That helps shake all loose salt off in chunks. I don’t want to soak a big deposit of salt. Then when I get home I crawl underneath with my pressure washer. I’m still driving the same SUV as I was whenever I was there last (2013 maybe) with no abnormal rust.

    For us my wife told me about the two pair of shoes. We usually put newspapers on the floor of the car, when we leave the launch site. After crossing the Salt Flats and getting back to the asphalt road, we get out of the car and change shoes.

    On Sunday we drive about 2.5 hours back to Brigham City. That trip knocks off some of the salt. When we get to our home, I park the car in the street and disconnect the utility trailer and take the car to the local car wash and buy one of the more expensive washes, especially a wash that sprays the under-carriage. I then go back to the house and get the garden hose out and spray the under-carriage with a good spray nozzle on the end of the hose and I spray the utility trailer, too. I have had the same utility trailer since 2007 and have taken it to the Salt Flats every year. I have had some repair work done on the trailer including the tail lights. Overall, the original cost of about $600 for the trailer has paid for itself. I get down on my hands and knees to spray under the car. I get almost all of the salt off, maybe a small clump will fall later, maybe even during the winter months. The under-coating that I bought from the car dealer has worked great. I have not detected any rust or corrosion on our cars over all these years.

    Rumble strips, hard car wash, every puddle that's reasonable, oscillating sprinkler underneath when home.

    Between dust & salt, I'm leaning more towards this option when I do eventually head out West-west.

    Since I’ve never been to UROC’s annual Hellfire Launch (held on the flats) before... I have to ask:

    How far from the end of the pavement & marker (40.7626, -113.8957) is the flight line?

    Does it depend on the year & salt conditions?

    The location is the same regardless of conditions. It’s about a five mile drive on the salt.

    Thanks Mr. Dugway!!! We will also be able to handle up to NON-Complex "T" from the same pad. Remember the 25K AGL Waiver! :)

    This will be the 31st LDRS I have been to.
    I even have a non-white rocket to fly.

    Got some projects moved along for LDRS. Thought it would be fun to try some high performance builds out on the salt since I'll hopefully be able to find them again.
    My 38mm build came in at well under a pound for everything not motor related. Only thing missing on the 38mm airframe is the 3D printed fincan I picked up form Addative Aerospace for making the build easy. Guess we'll see how fast those printed cans can go on the salt.

    I can’t figure why you wouldn’t argue with gravity during LDRS and dance above the salt, but, hey, it’s your rocket.

    I thought on the salt was... bad... for rockets.

    If you want to go on the salt, I’m gonna suggest you wait a week after LDRS — that’s when speed week is held for land speed records.
