    Who Used Chute Release for L1, L2, or L3?

    I try to congratulate folks when they get an L-cert and mention it on Facebook or the forum, but now that Chute Release isn't such a new thing anymore sometimes it's hard to tell if it was used in the flight.

    If you used Chute Release in your cert flight, could you please holler out your details?

    Rocket (with diameter and weight, if you know them)
    Motor
    Altitude (if you know it)
    And of course L1, L2, or L3

    I was prompted to do this when I heard someone L3'd with redundant Chute Releases at LDRS, which may have been a first.

    And while your at it... if you went drogueless, please post your data files over in the Drogueless Decent Thread.

    Dreaming of making the rockets I dreamed of as a kid (and then some).

    Modified Estes Partizon. Weight with out motor was 23oz. Payload bay included a Jolly Logic 2, Mobius camera and Play Mobile Bob. My 9 year old daughters astronaut. Motor was a H128-10. Altitude was 2408ft with a max speed of 425mph. Flight was for my L1 certification. Very windy day when I was up. So I decided to deploy at a low altitude 300ft. I had originally intended to use a guide chute. But a nearby flooded farmers field had already taken a few rockets. Chute release worked perfectly. Ours landed about 80 yards from the launch site on dry ground. Bob and the rocket were recovered with no damage. Great product. Thanks

    Flew my L1 Certification flight today with a Wildman Drago (2.1"dia/42oz/41.5"tall) on a H115DM-14A-14 motor. On board were three electronics, a BRB900 GPS tracker, a Altimeter3 and a Chute Release. All worked well for a successful flight to 2213ft with a recovery at 300ft with a 36" parachute.

    Last week I did my L2 successfully with Chute Release. I flew a slightly modified Madcow Torrent (color and decal scheme based on my sons' heavy metal rock band), which is 54" tall, 4" diameter, and 61 oz (sans motor), on an AT J270-10W to 3000 ft. I used motor ejection to deploy an 18" drogue, then CR to deploy the 45" main at 500 ft, and everything worked great! Click image for larger version.

    L1 success with an Estes Argent, pretty much stock out of the box. Used a little extra epoxy on the build. Flew to 2300 feet on a CTI H87 IMAX motor. 6.3cm dia "main" body tube and the stock 24" nylon Estes parachute. Chute Release hit at 400.

    Level 1 5/28/2016
    3" kitbash Patriot, 21 ounces dry
    H128W-10
    Estimated altitude: 2,100', CR set at 300'
    Winds were blowing pretty well at this event, without the Chute Release I probably wouldn't have attempted the flight. Even with a 300' deployment, my rocket landed a good 1500' away from the pad, with lots of sage brush between the launch pads and the recovery area.

    L1 Cert. LOC Cyclotron. AT H130W-14 drilled down to 7 sec. ~1200 ft. No drogue. The rocket free fall was not flat, but around 45 degree as the tube fin end was heavy. Chute release at 300 ft. Perfect flight on a windy day.

    I also flew an AT Warthog that day with dual 30" ultru light Sperachutes. 200 ft release (again, it was windy). I wrap both chutes with one chute release. I've tried several methods of wrapping 2 chutes with the chute release and have yet to find a method that fails. (not that I'm trying, it's just fun). I almost always set the chute release for 200 ft unless there is no wind. I got into rocketry 6 months ago. As long as I've been flying rockets, I've had a Jolly Logic chute release. I don't know what the rocket world was like before that. I have never flown any of my mid power rockets ( 4 AT, 2 LOC, 2 PSII) without one. For me, the chute release is as essential as the motor.

    Okay, now you've got me thinking about multiple chutes. On the one hand: recipe for tangling. On the other hand:must look AWESOME coming down on multiple chutes.

    The CR actually helps here, by preventing the chutes from wrapping around each other while reefed.

    How difficult was it to get a 36-inch parachute and Chute Release in a 54mm airframe? How long is the parachute bay? Any tips or photos of the setup?

    36" chute, JLCR fit pretty easily in a 54mm airframe. Done it several times, mostly in my WM Interceptor Sport. The Drago has a pretty long BT, so it would be even easier. I just fold the parachute normally, shroud lines tucked into the chute, then JLCR around that, attached to the swivel. Just be sure to do a shake test on your JLCR bundle before loading to be sure it'll hold together.
    Drago + JLCR + H399 = awesome sauce

    Fits just fine. As stated the rocket is 41.5" tall, plenty of room. I did put the BRB900 in the niosecone so that helped with the room for the chute.
