The GPSL plans are starting to come together. Hopefully the website will be updated in the next couple of days, but there is one matter I'd like to bring to...
http://linweld.com/cat/29.pdf K tank is 219 cu ft. When we fly a 1500g balloon with our usual 8-9 lb payload, we put almost all of a T tank in it. Sometimes...
According to the web... K tank = 219 cu. ft. of helium (this varies a bit from place to place). Follow this link, click on He pure and the PDF will detail how...

A lot will depend on your weight. With H2 and 6 lbs or less, you're probably OK with a K. The volume quoted by Kaymont for 1500g is probably for a NWS...
Hi All...just saw the discussion....I emailed Keith that 6 pounds (as Mark just mentioned) was the payload/parachute weight combo I'd recommend for a K bottle...
I have been discussing this with Bill The main Man the balloon dude of all balloon dudes. And want to also open this to any of you out there. What do you do...
Hi Joe, EOSS uses that fast release device that you made a prototype of to get shed of the shards immediately after burst. Another way is to fire the cutdown...
Joe, Although we've never flown light payload strings (too many experiment on the flight), I wonder about flying with an inverted parachute. I can envision a...
The following is from Luther Richardson, KI4AOJ: Â DREAMS: Doing Research at Extreme Altitudes by Motivated Students. DREAMS is a project of NASA Ames and the...
Bill's the expert here, he has done flights like this as controlled experiments. From a personal learning experience myself, (similar to fumbling around...
... Thanks for pointing out that easy solution to Keith. I guess I should create a new LIFTWIN website that explicitly includes VB300 as a small download as...
Howard...Arbonet did exactly this configuration last GPSL....it was a very slow ascent....if they have some GPS data up to the point where they reached the...
Hi Joe....THe Mojave desert is an interesting place to fly...I did my first flight there in 1989 from near Victorville, CA. We tracked it with not only a chase...
How crude. You actually had to use airplanes and helicopters to recover it! (That was a huge tongue-in-cheek remark in case anyone missed my humor.) Actually,...
Hi Pete....yes, that was way before GPS receivers so we used Direction Finding to guide the chase plane to the landing area....as it parachuted down we lost...
That makes for a terrific story with the chase plane seeing themselves fly by. That's kinda one of those mind-benders that probably took a minute or two to...
Of course, there's also a pretty fair chance that your payload string would fall right into the 'chute canopy for a REAL fast ride home. This has happened to...

Yup i remember all the flights were RDF and triangulation. The ultimate Fox hunts! I remember our first GPS unit. the antenna was still even back then small...
In 2007 GPSL was held in Grand Island, NE. One of the groups attending was from Maine. I believe the group was EOSRED – Edge of Space Research, Experiments...
We did the two balloons , but inflated them so they each provided 1/2 the needed lift. and one would eventually pop before the other, and then there is only...
Or until a weak bit on the payload string breaks off, thus unburdening the balloon so it takes off again. It's happened to us twice! The good news is that...
I participated in a flight with 3 balloons out in California with KC6CCC....two burst leaving one inflated on the way down. We could see the one balloon...
