    The RocketSim launch (simulation software) showed that I needed a longer delay…but that was the only motor I had. According to the software, the modified NORAD had an upward velocity of about 47 feet / sec when the parachute was deployed. That is approaching the edge of tearing the shock cord…but still "technically" in the "good to go" category. Well, it worked out!

    Sooo… Steve or erik please explain how/why the early ejection charges work.

    Awesome shot and rocket!

    Ahoy Erik! Please to meet you! I am the alieness, aka Gisela, A.P.A.’s (see tags –> "Alieness Postprocessing Agency ") founder and director and, uhm, sole employee too. =)

    Steve friends are my friends so I am very happy to see you here in flickr, welcome abord! Enjoy the ride! :D

    I´ve peeked your abum a second ago… do you have there a photo which would be the original version (not the same pic but the same scene) of this photo here I slightly tweaked, don´t you?

    Neat shot anyway. I´ll go see the video. *blink blink*

    Oops… Nice date today! -already today here- P-)

    Don’t feel stupid…. =)

    (Here is the grand 200 liters of Diet Coke + 500 Mentos video for those who do not know the reference)

    Esteban: more? Happy to…. The "Rocket Set" above right has the past… Next month, I go to the Black Rock Desert for some really big rockets. I am borrowing a Canon 100-400mm Image Stabilized lens from a friend for the event…

    benjiman: premature ejection is a bit of a bummer… ;-) Worked out fine here, but it can damage the rocket, or worse, if the rocket faces too much wind resistance, it might not be able to get the nose cone free and the chute deployed…. and then it becomes a lawn dart:

    Supersonic Inbound

    Each motor has a delay fuse before popping the forward facing ejection charge (gunpowder blasts forward within the rocket to push the chute and nosecone out). The fuse time needs to be appropriate for the rocket size/weight and motor size. Kits comes with recommended motor configurations. Custom rockets with custom motors, like this one, take guesswork and experimentation… and they can benefit from RockSim.

    Hi TheAlieness►GiselaGiardino…Great to meet you…and everyone else. I am really enjoying getting to know the Flickr community. Very cool.

    You got it. That is the same image…and I have another one from a fraction of a second after. Steve was taking a rapid succession on images…and I snagged a few of the ones I enjoyed most =) It was a amazing launch!

    Hi there Erik!!! Cool, I couldn´t see the originals for when jur-v sent it to me he had already made the black bar disappear. I just had to re-arrange the sky. ;-)

    Stev, I got an idea ( !!! )… after Resurrection, I was listening to the other Oakenfold songs and I got a very special feeling with Zoo York (from Bunkka) I thought of a challenge then: "Picture the song".

    I tell you a song, and you gotta find one in your album or upload one, or go take a picture to illustrate the song, as you feel it.

    How ´bout it? Accept the callenge? How would you picture Zoo York?
