Beginning Work on Construction of Certification Rocket!

Simple.

I am hoping to get certified with as little difficulty as possible, that's why my certification rocket is just a basic 3FNC rocket.

So far I have glassed the air frame, cut out the fins and centering rings, constructed and glassed the motor mount, purchased the motor case and spacers, ordered the tube couplers, nose cone, parachute and rail buttons, and generally have just been having a great time.

I'm a bit frustrated because one of my centering rings just disappeared and I've been looking everywhere for it. Can't find it.

My least favorite part about building a rocket (besides spending $$$) is the process of glassing the airframes. It's so sticky and messy! I don't get it how some people can come out with such a smooth-looking airframe that it practically glistens in the sunlight. Mine are so lumpy and stringy that it looks like it had been buried for a hundred years. But thankfully it's always something I can sand out.

I need to order a good altimeter for deploying the chutes. I'm thinking about ordering the Parrot Featherweight, but I'm still deciding. What altimeters do my rocketeer readers use?
