Callahan’s Express Launch

This summer’s weather in Tampa has kept the Tripoli Tampa’s launch pasture closed due to excessive water on the field.  Finally, the winter pattern started, and the daily thunderstorms have ended.  This past weekend was the Buccaneer Blast hosted by Tripoli Tampa and I was able to launch the Callahan’s Express. I planned on launching the rocket on Saturday. After seeing a couple of rockets break apart in flight and watching another one burn up on the launchpad, I decided to put my launch on hold.  Not to worry, I did launch it on Sunday.  So, read on to see more (including a video).Rocket Ready - Callahan's Express Launch

Ode to the PerfectFlite StratoLoggerCF

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.Closeup - PerfectFlite StratoLoggerCF

Avionics Sled

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.

The dual deploy altimeter is a PerfectFlite StratologgerCF.  I purchased this board from Chris’ Rocket Supplies.
