Okay, It’s been longer than I expected to create this next posting…  And yes, I got totally distracted from posting the Missile Launch System (we will get back to it soon).  The BIG distraction was I purchased a 3d printer, the QiDi Technology I Dual Extruder from Amazon.

Then I spent the last two weeks learning everything I could about designing parts using Autodesk’s 3D design software (123D Design) and printing them in 3D.  Using the software and printer I created a saddle and mount for an old Syma quadcopter camera I had laying around.  I fabricated a control switch and a holder for the Lipo battery.

On Friday, David Duncan and I went to the launch site and made two successful launches with the Missile Command System and Strobee. The wind was blowing from 9 to 19 mph (as recorded by my on site weather station);  that is why I am holding my hat on.

The first launch I used an AeroTech E20-4W single use motor.  On board is a Jolly Logic AltimeterTwo (which I highly recommend).

Flight Data from Jolly Logic 2
Max Altitude: 443 feet

Average Acceleration: 3.6 G's
Coast Apogee: 4.8 seconds
Apogee ejection: -0.4 seconds
Ejection Altitude: 440 feet
Descent Speed: 9 mph
Flight Duration: 38.5 seconds

The second launch is with an AeroTech E18-4W  RMS motor.
