The Estes "Model Rocketry Technical Manual" lists Featherweight Recovery and
Tumble Recovery as being distinct.  What is the difference?

How long is the Estes 3/16 in. (5 mm) MaxiT launch rod?  I 'd like to see if
I could pick up a suitable rod in the local hardware store.
By the way, I am just getting back into model rockets with my kids, having
not touched rockets since high school.  I had forgotten how fun this ...

A long time ago someone posted a video or a link to one that showed the
rocket fins fluttering (resonant vibration) as it flew.  I would like to see
it and show it to some fellow rocketiers.  Any one have the video or link
that they can post?

In the "Handbook of Model Rocketry" By H. Stine there is mention of a 3
station tracking method to determine the altitude of your rocket. It
makes use of only the measured angle of the rocket at peak altitude
(with respect to the ground) and a baseline that is a specific length

Greets. I'm in the process of building my first largish rocket (29mm)
and am a bit on the horns of a dilema.  I fully realize that this may
be a religious discussion, but I need to know whether I should get some

so if I lost my NAR number how do I get it back, and I wonder if my certs
will be any good...

I have a really cool idea for a rock I want to build, but I have no
clue how to do some stuff for it.  What I want to build is a 24 in long
(at most) rocket, that will fly on a b/c engine.  But what makes it
