Other than the sun being a bit hot, this Saturday launch was perfect. Mostly clear skies with just a bit of high clouds, temps in the low 80's, and almost no wind.
I didn't arrive until about noon due to other obligations in the morning, but didn't miss much of the big excitement. A friend David came with me to see his first High-Power launch. He seemed to have a great time but got a bit hot by the end of the day. My father arrived mid afternoon and watched quite a few launches also.
Some of the highlights were Brian Elfert's Level 3 flight on an M1315, Ted Cochran's PML Endevour multi-stage flight, several 8,000 flights, and an I-235 drag race. One spectacular "Cartwheeling Flamethrower" cato reduced a quantum tube rocket to a limp plastic puddle. The planned main attraction, the three stage BHR (Big Honkin' Rocket) flight was cancelled at the last minute when one of the altimeters failed during preflight.
I took a leisurely pace and flew only my mid-power rockets. At first the lines were long, by the end of the day there weren't any lines but I & everyone else were hot and moving slow.
|Jeff||Aerotech Initiator||Aerotech G35-7W SU||2000||Great motor for this rocket. Flew very nicely. Made a soft "stand-up landing" without even sticking the fins in the ground.|
|Jeff||NCR Archer||Aerotech G64-4W RMS||1'st flight after rebuild (previous owner had a lawn dart that crushed the forward body tube and broke the nosecone bulkhead). I modified it to split at a new coupler just forward of the strakes and added a bulkhead to the upper section so now it has a large payload bay for future dual deployment mods or other use.||500||Nice flight, though marginal on power. Deployed nicely: new chute protector method worked though slow. New bulkhead, repaired chute, and plastic riveted nose cone all held together fine.|
|Jeff||Estes Big Daddy||Estes D12-5||1st flight after rebuild (previous owner had 2 consecutive lawn darts). Broken nose-cone bulkhead repaired using Plasti-Zip CA glue. Removed 1/2" of damaged bt and added some nose weight to compensate. Used 22" nylon chute from Initiator (no wind).||700||Excellent flight. Very stable, good ejection.|
|Jeff||Completely Custom Cardboard||Aerotech E11-4J RMS||16" chute + 10' crepe streamer. Peeled MMT tube so motor would fit, but still tight. Taped in RMS case.||800||RSO categorized as a "Heads-Up" flight and LCO was scared, but perfect flight, lots of black smoke. Good motor for this rocket. Motor case held tight.|
Yet another great day!

Note to self: Bring more water and a cooler. Buy a shade awning. Bring white vinegar to clean RMS cases on-site.
