I still haven't flown mine, and I doubt that I will now, at least
without some heavy modification.

problems related to construction: launch lugs are ***(brass collars
in 1/32" ply anchors)--replace with normal lugs.  shock cord way too
short --  after installing per instructions, cut about halfway in the
open section, and attach longer cord (maybe thin kevlar cord?).
Parachute compartment too small (and this will only get worse if you
do the extending of the shock cord) -- not much you can do except
maybe only buy one of their larger kits, or trust that nose blow
recovery will be safe enough.

potential problems...  motor retainer ring appears to be a weak link
(actually the anchors to the body, not necessarily the ring itself)

Hmmm... square rockets from Stellar Dimensions...

Their ad in Sport Rocketry says something like "They're different,
they're weird, they're better!"

My son is highly impressed with the ad and their web page
(which is www.tx3.com/~netman). But before he spends his money,
has anyone here had any experience with these kits?

I'm sure they fly, but how well and how high? How are the kit
instructions? The materials? The chutes? The colors?

I've got a Spinnaker (now retired) with over a dozen flights on it.

I recommend white or yellow glue; I built mine with medium CA and found
that in a couple cases I didn't get things perfectly fitted due to
too-rapid setting; in at least one other case, the joint wasn't properly
filled with glue, leading to trouble later.  In addition, the pre-tack
lubricity of a glue like Elmer's helps in getting pieces together.

The parts are laser cut basswood, and >very< accurately fitted; sever of
the subassemblies can be dry-fitted and will stay together until you pull
them apart.  I did note that the grain direction in the fins was less
than optimal; it's perpendicular to the root, which is okay, but there
are unsupported projections fore and aft of the ends of the root on the
Spinnaker and a couple other designs that might be prone to break off.  I
glued a piece of balsa strip onto the "back" surface of each fin to
forestall that outcome.  Also, the tabs that hold the motor lock (in
itself a nifty bit of laser cut teflon sheet) to the body are prone to
splitting off, and could stand to be reinforced with small sections of
1/64" ply or cross-grain basswood s***from the kit wood.

These models don't want any filling or priming; they have laser engraved
details on most of the exposed flat surfaces.  I'd suggest careful (but
not excessive) sanding, followed by two or three base coats, a
contrasting overcoat, gently sanding through the overcoat to enhance the
engraving, and a clear coat to restore the gloss.  Alternately, for the
"natural" look, you could just sand and clear coat or that "carpenter's
rocket" appearance.  (BTW, if you don't like the engraving, you could
assemble the model with it on the inside, except for the fins, and a
little Fill n' Finish would get rid of it there, giving a more
traditional smooth surface.)

The Spinnaker and one other 18mm motor design suffer from lack of space
for the parachute, and I don't feel the 1/64" ply parachute tabs are
necessary or a major improvement over the current Estes method for
keeping suspension lines attached to the canopy; in fact, though, the
smaller SD rockets recover without damage on nose-blow tumble, and don't
really require a parachute.  The shock cord in mine was >much< too short,
but that's relatively easy to rectify by a number of means.

These rockets are relatively heavy for their size, but that's not a huge
disadvantage; I found my Spinnaker to fly well enough with A8-3, B6-4,
and C6-5 motors, and later (after some mods to get around damage) on
A10-3T and A3-4T mini motors.  The fins are canted to give spin in flight
(more for looks than stability, according to the designer), and the spin
tends to lead to parachute tangles, but contributes to the gentleness of
tumble recoveries.

In all, these kits can be assembled by anyone who's built a couple
models, and are not excessively priced at $10 for the 18mm models.  I'm
thinking I should get the 8-sided, D-motor one to see how they do in
larger sizes...  B)

I wrote a kit review of the Xanadune and posted it on my web page at:

http://www.FoundCollection.com/~burkefj/sub/rocketpage.html

Under kit reviews.  It has some of the same concerns expressed already.
The owner of the company saw my posting of the review, and was nice enough
to send me a free kit as a thank you, which as soon as I get time to
review, I'll post also.

They ARE different. They ARE wierd. They are not better, nor are they worse.

They fly as well as any questes rocket. With the canted fins, most of them
don't fly very high. The instructions are good. Materials are laser cut and
fit perfectly. The chutes are standardplastic. I'm not impressed with the
shroud line attachemnt, as it makes the chute stiff, and they don't stick
that well. Colors: it's raw wood, and you can paint or stain it the color of
your choice.

My only complaints are (1) the basswood has grain like balsa, and does
crack, (2) the recovery compartment is tiny and hard to pack the bulky
chute, and (30 the shock cord is WAY too short.

Give one a try. It *IS* different!

You mean like a redi-roc :-)

The "kit" I gave Mary was 2 lids from Long John Silver meals. No food!
