    DSCN0505.JPG DSCN0506.JPG DSCN0496.JPG I did some painting yesterday, repainted the Tactical Toothpick and did some detail on my Ventris. Was a good day for paint. I need to learn how to take good pictures of rockets. DSCN0500.JPG

    First launch of the year! In the morning, the wind was pretty gusty and pointed in exactly the wrong direction, and I feared the whole day was going to be a washout. Flew my Odd'l Cyclone on a 1/2 A3-2T and my trusty Quinstar on a D12-0 just go get things going. Those two are always fun.

    Eventually the wind came under control and I was able to do some flying. I started with the maiden flight Deuce of July on a couple of B6-4s. Not very high but successful. Then I maidened Alcubierre on a Questjet C12-4. The up was beautiful... the down, not so much. Somehow (still not sure) the chute didn't open properly and on the way down the nose slammed into the ring and caused some damage. It may not ever look as nice again, but it should be fixable and will fly again.

    The IRIS-T went up on another C12-4. Right off the rod is turned sideways away from the flight line, and then kind of straightened out. It came down in a lousy area and it was a heck of an adventure to go find it... but happily the chute snagged in some weeds and the rocket came back pristine.

    Then I sent up the Diamond Cutter on a C11-3 and then a D12-5 to test out my new JL Altimeter 3. Two perfect flights.

    Finally, the Deuce of July on two C6-5s. The first time I forgot to tape the motors in and got my first ever core sample:
    June 8 launch-1.jpg
    Thankfully the ground was soft and it suffered no damage at all, not even a scratch on the paint that i could see. I sent it right back up on another pair of C6-5s (this time with motors properly taped) and had possibly the best flight of the day, nice and high and easy recovery. I also got my one good picture of the day, a screen grab from a video:
    June 8 launch-2.jpg

    Got a total of nine flights in, all rockets came back. Heck of a good day by the time it was done.

    Glad you got some flights in Neil and all your rockets back.

    Got signed off on my L2 attempt and flew 2 LPRs, a Super Neon XL on an E28-7T and the first flight of my Estes Star Orbiter on an E23-7.

    Found my Estes Mean Machine in the attic that I started building 42 years ago and never finished, found this forum and signed up.

    Drove to Geneseo, NY to fly with MARS and recover my lost Darkstar Jr from the Police office at the University:D. Flew out of sight during NY Power and I never thought I'd see it again.

    Thought how I'd've enjoyed flaying with at Geneseo, but had a prior comittment down in WV. It was fun too, so I'm really not complaining.

    I don't suppose there was a Zenith II sustainer in the lost and found?

    Packed my rocket stuff up somewhat for the move to Jonesboro AR. Start work June 14th as an engineer. My only gripe about Jonesboro is no Tripoli or NAR prefectures. Gonna be a 5-8 hour one way trip to fly rockets but I get some higher waiver options.

    Worked up the data from yesterday’s Ute Tomahawk G115-F10 flight. 8 seconds of burn is awesome - and about 4 sec too far into the gravity turn :)

    Wow. It slowed during the sustainer burn. Regardless, congratulations. That's a pretty cool flight.

    Did you use the Eggtimer Proton or Quantum for this one? Would you mind sharing your settings?

    Oh, that's a Proton. The nice, smooth Accel and V data don't come from Baro data :)

    Green line is the filtered Baro velocity.

    I just fetched the settings onto the phone. I'll post them from there.

    Okay, here are the setting screen shots:
    IMG_1094.jpg
    IMG_1095.jpg

    I’m not using the Accelerometer v Barometer Altitude cross check. I don’t think it’s working for me. The accelerometer doesn’t seem stable enough. Intercept drift with time on the pad. I can illustrate with graphs later.

    @BDB , I took a long look at this today. I can add pictures later, but I'm coming to think the Baro data is reading high during boost, rather than the Accel data reading low. Well, it reads low - and really low near apogee - but the quirks that show up near apogee aren't important for setting staging limits.

    I took both the Proton and OR Sim exports for both the G78-E22 and the G115-F10 Ute Tomahawk flights and put them in one dataset - then started looking at how Filtered-alt, Sim-alt and Accel-alt (And velocity) compare.

    The Accel data and the Sim match closer than the Falt for both flights, in pretty much the same way. I still suspect that I'm not getting good isolation of the avbay from pressures at the base of the rocket - that my wiring chases duct low pressure next to the nozzle during burn and high pressure during separation.

    We (PyroSkark & I) built a couple of rocket cradles whist waiting for NZ customs to clear our inbound packages...

    [​IMG]

    Build Cost US$24.00 and an hour of measuring & cutting.

    Need to glue the inspection hatches on the 90 elbows as they keep popping open, and need to add closure caps to the uppers.. will pick them up tonight.

    We also took delivery of:

    2 x 25' quarter inch super soft & fantastic looking Kevlar harness with pre-fitted nomex blankets & a couple of Top Flight Ultra X Form drogue chutes from OneBadHawk.

    Many thanks to Teddy for his advice & recommendations - and the shipping to NZ was just on a week.

    Looking forward to showing off his wares, at the next NZRA members launch day.

    Got my Drexel tool out and installed the drum sander in preparation for the Apogee Level 2 build.

    You're quite welcome Dean..
    And thank YOU very much for the post..
    They're always so nice to read..
    Now, if I may, I'd like to ask something of you,,
    When all is said and done,
    I'd like very much to see a pic of a rocket hanging on my harnesses
    floating gently down over the beautiful countryside of New Zealand...

    I have seen a lot of pics rockets hanging on my harnesses from all over the world,,
    but haven't yet seen one from your wonderful home country..

    Still agonizing over which rocket I'm going to build as my first two stage to launch. An upscale Nike x or my own design that looks like a navy rim with a booster missile.

    While researching parts for them I stumbled upon most of the parts to build an oop Estes ventris on the Estes website so I ordered them today. One slotted 2" pro tube, one plain 2" pro tube, the plastic transition, a 2.5" pro tube, the 2.5" plastic nose cone and just for kicks a 2" plastic nose cone. They have the 29mm motor mount two but I have one and the retainer laying around. All I am really missing is the centering rings so I'll have make some up.

    Flying on an Aerotech J245R to an estimated altitude of 4000 feet. Ejection delay drilled to 10 seconds. Great panoramic views of a scene that is like no other. NSL 2019 was a grand success. Thanks to NAR and ROC.

    Shall do, although I can't guarantee that we will get a Hobbit in the shot, but we can only try.
