    4 / 4 - 100% Complete, Goal Achieved.

    Thank you to all those that have provided comment & guidance on our build, the feedback has been appreciated.

    And now for PyroSharks L2 flight....



    Enjoy !

    And now we sit back and contemplate what our next project shall be. Should we go smaller / minimum diameter 29mm or 38mm or should we go all out for an L3 build. Lets have a cup of tea or two and think about that one.

    Also... (proud father voice) ... PyroShark was awarded the 2020 'Arthur Alan Thomas Junior Rocketeer Award'. He's a bit shy on this one, but may comment here after he reads this post.

    Congratulations! Its good to see that NZ has a thriving sport rocket group!

    Im still very confused, as you speak of both you and your son getting certified, but the videos and pictures appear to show only one rocket. Are the rules different in NZ? Can a team of people share a rocket for certification, unlike over here where it's one-dude-one-rocket for certs?

    A good question - The local rules for L1 & L2 state "The rocket must be built or assembled by the flyer" and for L3 this changes to "The rocket must be built by the flyer."

    Interesting, it appears the NZ codes don't explicitly require a certifying flier to build their own rocket for their own cert

    For example, the NAR line item:
    "The member attempting certification must build the rocket that they wish to use for their certification attempt. The model may be either scratch built or a kit and the rocket must be constructed in such a manner that it will perform safely under the additional stress of an HPR motor. Teams attempting to certify cannot use the same rocket, but rather are required to each build their own model. In addition, the member must use an active recovery system for their certification attempt, which usually includes parachute recovery; details of these recovery methods are described in the Definition of Active Recovery."

    This might be the only example where being on the arse end of the supply chain actually works in our favor.
    Everything else costs 2X the USA prices :( and supply is _very_ limited.
    We have had people waiting 14+ months for motor orders.

    Very valid consideration. Allows more folks to leverage limited material
