Tripoli Level 1 Re-certification - 6 Nov 2011

A few days after returning home from Iraq I purchased a PML Small Endeavour (that's how PML spells it) and got right to work on re-certifying Level 1.  My son and I were excited to complete the build - I think it only took us a week from start to finish!  This was a very easy rocket to construct.  I'd recommend it to anyone trying to certify or those who want an easy 38 mm rocket to fly.  This was my first time working with the PML Quantum tubing.  It's very strong and easy to work with.  After a little sanding it bonds well with standard 30 min or 1 hour epoxy.  I made three small changes from the standard kit instructions.  First, I added glass cloth fillets to all six fins.  While probably not necessary for an H motor, you never know what you may want to fly later on.  Second, I cut the leading edge of the launch lugs at an angle to reduce drag and to give the rocket a sleek look.  And third, I added a motor retainer from Aero Pack.  When I certified the first time in 1995, masking tape was my "motor retainer."  The Aero Pack retainer was very easy to install and much faster and cleaner than tape.




A few weeks after completing the build I went to Plaster Blaster X hosted by Tripoli San Diego to certify.  The most challenging part for me was putting together the Aerotech RMS 38/240 H73J reload.  It had been a long time since I'd built a motor.  After installing the motor, packing the parachute, and turning on my AltimeterTWO to record basic flight data, I got the approval from the RSO to position the rocket on the pad.

"Sky is clear, range is clear, going in 3-2-1-Ignition!"

And with that I was re-certified Level 1.  I only wish my Level 2 flight went as smooth.
