Hello, I will be attempting a two-stage flight this weekend using a PML Quantum Leap. Most likely using Js for both stages. Does anyone have experience with using shear pins to secure the two stages?...

For those of us making use of the call-in windows, here's the jet stream forecast: (Updated for 2 PM MDT Friday) The menu for the different days is here: The jet stream associated with that big trough...

As for RSO, it would be nice if this year we had the RSO set up with the flight cards in a tent slightly distanced from the pad lines (as is often done at large events), as in the past, it has been ea...

I volunteered by email for RSO or LCO on Saturday and Sunday, 12-2.

Clearly they shouldn't have been flying that sparkie that day, but for an explanation that make it more understandable about why they did, see the first-hand account on post #60, from the SLI mentor J...

Unfortunately, there is a third camp in the comments in that thread that is loudly proclaiming that rocket launches will cause fires, no matter what mitigation steps are taken. That's not exactly hel...

We can leave my tower set up for 38mm shots and Sean's tower for the 54mm birds.

For what it's worth, the updated forecast this morning calls for moderate Westerly winds of 7 mph until noon. Fingers crossed.

I'm going to be prepping today and tomorrow, also. Not sure how far I'll get, but I have a plan now for connecting a Featherweight av-bay to a dual-deploy chute holder that I can use for all of my 38...

The weather near the ground looks marginal, with cool temperatures, 50% cloud cover, and winds around 13-15 mph. But the upper level winds are good, with very low wind speeds:

Congratulation on getting to production. Do you have a price yet?

Wow, that sounds like fun. How many are there? I almost hate to ask this, but can anyone explain concisely the rules regarding expired cert motors? Can they be flown on commercial launch days, or ju...

I can't wait to see some of these thrust curves!

For 2 ??What size powder charge you using. I will give you a dollar if you do the ground test. 😉 I thought I would use 3 pins. When you use small altimeters and batteries, you might be surprised ho...

Thanks. You can also use a single Raven, with its four default output settings, to do both primary deployments and both backups with one altimeter. The default apogee output is accelerometer-based,...
