A steel rod would be enough. You want something that will flex as little as
possible. They're only a couple bucks if you get them at Home Depot, and
can easily be cleaned.
Why are you considering carbon-fiber?
No real reason, other than I already have a 48" long 1/8" rod. It seems
less flexible than an aluminum rod; and I assume it is easier to care for
than a steel rod (no rust). And I was intrigued by the passage in "the
handbook" about tests showing that an aluminum rod actually whips less than
a comparable steel rod.

Al rods are the worst case...Even if you consider a 1/4" rod.. You want "as
stiff as possible".
If you don't want rust, use stainless steel (a slight bit more expensive).
However, rust isn't really the problem! (many times). It's the gunk that
will build up due to motor exhaust. Being able to run sandpaper or steel
wool on the rod to clean it in the field is a good thing. In fact, cleaning
the rod before a day of launching (reguardless of the material) is a good
And I was intrigued by the passage in "the
From years of flying, I can't agree, unless the rod is made of very cheap
steel! You ever seen flights off the AT (RCS) "Mantis" pad with the AL
rods? A few bucks at HD will get you a steel rod...
Remember the "handbook" also says no EX motors, but fails to mention that in
the early days, Stine was flying "EX" motors!
I got rid of my Mantis almost as soon as one fell into my hands. What a
piece of crap. That thing had more moves on lift off than Michael Jackson
back in his thriller days. The real fun came in trying to determine just
where in the hell that rocket would be heading when it finally came off the
That is a nice video.
Several aspects I particularly like.
Dissolve and animated graphics. God bless MacOS.
Fast paced music.
Very good launch audio but it still sounds "unrealistic and tinny".
Variety of propellant styles is well visible.
The time compress build is truly sweet. "Consumer interaction".
Areas for improvement
HD everything. DVD.

In production if you are married to AL, double its diameter and go with
7075. Change out the launch lug parts in kits. Bigger lugs still work
with smaller rods.
Offer a rail guide specific to your kit slot. Rail too.
You need a 3 min version of the video for trade shows.
Last I checked you never did a powered landing yet.

wel, since you said we could I figgured we should start a new thread about
has anyone had any success getting public access to air their model rocketry
videos? I would think that this could be a good way to get the general
public to see some of our hobby.
our local community does NOT have a public access channel. they are too
worried about political groups taking it over
paranoid idiots, sigh.
I'll see if I can get other areas nearby to look into it. what i really need
is a bunch of AV nerds to take over the video part of our club so the
president can actually FLY a rocket once in a while
