Centuri Vector-V 1.37X next to 1.00X clone. Glamour shot #2, June 10, 2012.
2006-10-29Prototype II-B Flight I lost sight of the rocket (again) on its way up, but I saw the ejection charge's flare against the dark sky. Thanks to the EMERGENCY ORANGE, I found the model 100 feet upwind of the pad, even with the fading light. - C6-5 [More]
Prototype II-B Flight About 500 feet up on a B4-4, the rocket arced away... AND SEEMED TO DISAPPEAR INTO THE CLEAR BLUE SKY. (Transitional lenses don't help!) I found the rocket 300 feet from the pad, with some minor fin damage. - B4-4 [More]
Prototype II-B Flight 24 inch streamer let rocket land parallel to the ground about 100 feet from the pad. Need to extend elastic shock cord from 24 inches to 30 inches to avoid snapback damage. - A8-3 [More]
2006-10-21Semroc Tau Zero Flight Arrow-straight flight, weathercocked slightly into the breeze. Landed 100 feet away from the pad.Body tube and tail assembly undamaged, but nose cone tip broke off. Heard the impact, so 1.75 by 18 inch streamer isn't long enough. - C6-5 [More]
Semroc Tau Zero Flight Motor decided it was a B6-2, and blew rocket into 3 separate pieces while it was still upward bound. I recovered the nose cone, but everything else was lost. Not happy about THERMONUCLEAR Estes ejection charges! - B6-4 [More]
2006-08-19Semroc Tau Zero Flight Partially ejected motor dragged the rocket down tail-first, and busted off an outer fin on impact. Too much descending drag from the folded 1.75 by 36 inch streamer.Used medium CA for repairs. - C6-5 [More]
Semroc Tau Zero Flight About 150 feet up, the rocket veered to one side. On recovery, I found didn't get the broken fin back on exactly straight, which caused the swerve.Time to retire Prototype I! - C6-5 [More]
Semroc Tau Zero Flight A bigger, beefier screw eye (Semroc SE-14) resolved this design's stability issues.Kicked the motor and free-fell to gouge the nose cone's shoulder.Needs a motor hook! - C6-5 [More]
2006-07-15Semroc Tau Zero Flight The launch director asked if I noticed that this flight was a little less stable than the last.I didn't, because I was too excited to get this design into the air on a B6-4.Another good flight. - B6-4 [More]
Semroc Tau Zero Flight I remembered to tape the engine in.(Amazing how much more effective that is.)Ejection charge popped the streamer, and onlookers made approving noises. - A8-3 [More]
2006-02-06Sirius Rocketry Interrogator S-011 (Kit)  Review
Brief:
I had seen Sirius Rocketry's "U.S.S. Atlantis Refit" online and was
pretty intimidated by its apparent complexity. However, when I saw the Atlantis
in person at NARCON 2006, it was smaller than I expected it to be. What
really caught my eye was a new kit that David J. ... [More]
2004-09-15Centuri Groove Tube (Kit)  Review
Brief:
Decades before Quest Aerospace's "Totally Tubular," Custom Rockets'
"Razor," and the now-defunct Rogue Aerospace's "Hex
Courier," the Centuri "Groove Tube" was my first encounter with
a 6-pack of tube fins. I enjoyed this kit while I was ... [More]
2004-09-13Semroc SLS Javelin (Kit)  Review
Brief:
Centuri's original "Large Scale" rockets were called "high
power" kits in the late 1960s and early 1970s, which used thicker-walled
body tubes along with hard balsa fins and nose cones. Semroc's "SLS"
series, which we now call "mid power" ... [More]
2000-07-04Semroc Javelin (Kit)  Review
Brief:
The single-stage 4FNC Centuri Javelin was my very first model rocket, as seen
in this photo of myself from the early 1970's. Estes model rockets were only
available by mail order in South-Central Idaho back then, but I could easily
buy Centuri model rockets at a drug store in my ... [More]
