    My son Paul and I traveled to W. Palm Beach to take the Level 1 High Power Rocketry certification test with the Florida Spacemodeling Association. We failed on our first try with the PAUL DZ (LOC Expediter) on an H115 because of a manufacturing defect on the tie bar (see photo). On our second try, with the PAVEL 3 (Wildman Darkstar Jr) on an H135, all went well and we got certified with a flight of 2011 feet. Windy day but JL Chute Release saved us a lot of walking. The TeleMetrum/TeleBT combo worked great and the "live audio reports from the rocket" attracted a lot of attention. L2 soon, I hope.

    The video cameras had issues and we could only manage to make this video of the day:

    Congrats on L1 :)

    Eye bolt or kevlar loop are common upgrades to fix / not use plastic loop on nc

    L2 that darkstar jr will do it :)

    Congrats on L1. By the way, those NC loops are meant to fail!

    Congratulations! Well done!

    With plastic NC's like that, I usually drill a couple of 1/2" holes in the thing and pass the shock cord through the holes for attachment. Far more secure than any of the molded loops...


    Later!

    Congratulations, welcome to HPR! Yeah, replacing the thin plastic loop with a kevlar loop is a good idea anytime but an absolute necessity with large plastic nose cones, like on a Minie-Magg for example.

    Welcome to High power! :dark:

    As others have mentioned....NC did not have malfunction....it's a bad design,:facepalm: I'm surprised the RSO didn't catch how you attached shock cord.

    Ditto, Congratulations, I hate when that happens and don't trust those plastic "thingies" I go so far of using a high grade epoxy with a plywood bulkhead and finishing screws around the periphery. Haven't had an NC subvert that. I've done toggle bolts but they eventually start to rip through the base. Kevlar loop is down, dirty and a very workable easy way out to get a cert in the can.

    Welcome to high power. You will find sitting much easier now. An empty wallet isn't nearly as uncomfortable. Good job and good luck working towards L2.

    Congrats. I cut off the coled end of the shoulder and use a coupler bulkplate in the NC. That way I can put an eyebolt through it. After you cut off the end, leaving most of the shoulder, rough sand the inside where you are attaching your bulkplate. If you are going to use your nc to house your tracker and/or other electronics, drill the appropriate-width hole in your bulkplate then attach the eyebolt to it. I have found that a generous amount of LocTite epoxy for plastics works very well. Make sure you have a good bead on both sides of the bulkplate.

    Congratulations! Look on the bright side: with the failed nosecone loop, you *had* to fly again. I'm sure they had to twist your arm real hard, too!

    Congrats. To save money, pout your wallet in your L1 bird and shove the biggest motor you can into it. Lose the wallet now and you will save a lot of money in the long run.

    Big Congrats on L1 Cert. Thank you for telling us what happened on the first try. I definitely will be looking into replacing the plastic loop with something more robust. Caley Ann
