To have a traditional dual-deploy high power rocket, you must have a flight computer. This flight computer has a built-in altimeter and programmable logic to fire pyrotechnic charges. To do my Tripoli Level 2 certification flight, I wanted to use a flight computer to get practice for my Level 3 attempt. After reading reviews online I decided on the StratoLoggerCF built by PerfectFlite which I purchased from Apogee Components. I have been very happy with this computer and have flown it on numerous flights. So, without further ado here is my ode to the PerfectFlite StratoLoggerCF.
When I went to my first couple of launches, I noticed that a lot of people had stands to hold their rockets while they prepped them for flight. There were metal and wooden cradles that worked well. I also saw a PVC cradle that looked easier for me to build.
PVC pipe is easy to work with. It is like putting together tinker toys (that reference dates me, I know). As this rig will not be holding any water pressure, buy the PVC glue that does not need a primer. That eliminates a lot of the mess.
Saturday is the final day of this course. On this day, we all get to see or rocket motors fired from John Wickman’s test facility. So it is time to prep our motors and finish Rocket Motor Design Class – Static Test Day.
The agenda for Friday was mostly concentrated on finishing our rockets in preparation for the static firing on Saturday morning. The propellant had cured overnight and was ready for final motor construction. Let’s review what happened on Rocket Motor Design Class – Day Three.

Rocket Motor Design Class – Day Two started with a discussion of solid rocket motors. Interesting fact, one of the first useful American solid rocket motors was made in World War Two. It was used to assist U.S. Army Air Corps bombers in taking off from small Pacific islands as many of the runways were very short. The motor was made with ammonium perchlorate as the oxidizer and asphalt as the fuel.
I signed up for this course a few months ago and it started today. You can find out all the details at Design & Make Your Own Solid Rocket Motors. I flew into Denver yesterday, rented a car, and drove to Caspar, Wyoming to attend this class. After dodging a tornado, driving through a hail storm, and siting antelope; I arrived. So let’s start with the Rocket Motor Design Class – Day One.
One of the things I hate is shaking spray paint cans when I am finishing a rocket. I am not interested in getting a paint gun and thinning paint, cleaning, etc. So I end up stuck using spray paint cans.
Many times, the cans have been in storage for a long time and it takes a lot of shaking to get a good paint result. Enter the MixKwik spray paint can shaker! Continue reading “MixKwik Spray Paint Can Shaker”
When I decided to get back into model rocketry, I really did not know a lot about high-power rocketry. After attending a launch, this facet of the hobby really excited me. Surfing the internet led me to many sites and sources. One source was this book. Here is my book review Make: High-Power Rockets by Mike Westerfield.
Book Review Make: High-Power Rockets
This is a electronics sled for an avionics bay in one of my rockets. It will be placed inside a Binder Design Excel 4-inch rocket for my Level 2 Tripoli certification.
I used 1/8-inch basswood to make the sled. I cut it to fit inside the bay with a hobby knife.
