    The Lazy RSO's motor guide

    I won't say I need help, since that would imply I was planning to work on it in the near future. Truthfully it's just the thrustcurves alphabetized and thrown into a word doc by impulse. But if anyone finds it useful or worthy of updating from the last 5 years, they're welcome to try!

    The Lazy RSO's motor guide

    Been awhile since I've signed in It really isn't. I created It 6ish years ago before I was married or had a kid and when my career was significantly less challenging lol, but never completed the L2/L3 portions and definitely haven't kept up with additions like the Qjets or C5. I granted...

    Estes Pro-Series Patriot 2066 Clone Build

    I used Solidworks for all my solid modeling, drafting, and flow simulation. Unfortunately my old college laptop that had the program (from days as an undergrad research assistant) has kicked the bucket, so I no longer have that windfall lol

    Estes Pro Series Terrier Sandhawk

    Start with 1 per instructions, but be prepared to adjust that amount if needed to get the balance correct. (Once you've built it and put the finish on, check the CG vs CP and adjust accordingly)

    Can you change delay on a single use motor?

    Can you change delay on a single use motor?

    There are not zero-delay composite motors. Composites have a core (hole) up through the middle that exposes the front bulkhead (and delay grain) to the full chamber pressure. Drilling the delay of a composite motor too short (under 3-4 seconds) is a smooth way to have your rocket start...

    Hey that sounds familiar. My Astron Explorer lost 2 fins when the lines caught back on the tips of a vent pod. Still need to glue those on.....

    The Lazy RSO's motor guide

    Hey Chuck, I'd say the last time I updated it was around December 2018. I'm going out on a limb and guessing there's been some changes in the motor availability since then, so I'm afraid it's definitely out of date. Since then I got married, bought a house, and now have a 1 month old baby, so...

    What did you do rocket wise today?

    Its been awhile since I've logged in. Work has been pretty draining, and my wife and I gave been preparing for our first family addition in a few weeks. So, not a lot of time has been available for rockets recently. But not today! Im out working NASA Student Launch with the rest of the NAR...

    Cleaning RMS Motor Hardware...

    A school group that was out at HARA this weekend brought a couple bulk bottles of acetone for case cleaning in between flights. I'll admit that was a new one for me
