Build your rocket, fly and recover in front of witnesses (your local rocket buddies who are members of whichever national org you want to cert with), get your cert. Easy Peasy. Why cheat ? There's no cash prize or big trophy awarded.
Anyway it's easy enough to document your build with your favorite digital recording method if you feel the need.
Yeah I don't overthink this easy PEZ the person who sold me my motor day of the launch even help to guide me. You can certainly include your family if you're wanting to build some family fun into it but really it's easy and fun you'll love it
One can go into somebody else's shop and use their tools and expertise to guide the making of parts. I take it the candidate has to wield the tools, mix the epoxy and make the bonds. Nothing wrong with having someone looking on coaching you.
I've been known to go into a better equipped shop to use the tools to make the parts and then bring them home to finish off the rocket. Also some shops are better equipped to do fiberglassing of large tubes so there
is nothing wrong with using a friends tools and fixtures to get the job done. I bring my tubes, cloth and epoxy along with trays and rollers. There's nothing in the rules that stipulate where one "builds" the rocket.
I've had another stack cut a set of fins for me of which I find no different than buying a kit or collection of parts. Builder must put together, rig it, load it and fly it.
Buying a built rocket from someone else to certify is a mortal sin though. Kurt
I've signed off on a few L1 certs, and I always ask them things like "where is the cg/cp", "what epoxy did you use", "thrust to weight ratio", etc. Sure someone could answer this on a rocket that someone else built, but the point is not just testing their construction skills, but also if they have the base knowledge to fly a HP rocket safely.
