Brief:
Inspired by the movie "Honey, I Shrunk the Trident", this flagship of
Fliskits was inspired by the Estes classic ducted-ejection charge Trident.
Micro-sized and finely detailed, this rocket has an impressive appearance and
is a very challenging and enjoyable construction project.
Construction:
The main body tubes are BT-5 (13mm), with 3 side tubes that are, I'd guess,
BT-2's that look more like 18" launch lugs. You also get an assortment of
nose cones (9 total), amazingly detailed and intricate water slide decals, 1/16
balsa finstock, assorted basswood toothpick-sized stock for the details, and
Kevlar®/cotton
shock cord with a plastic chute.
The instructions and illustrations are very thorough and complete. While you
need good building skills for this rocket, you don't need to figure out how to
make things work--just follow the plans. My set of instructions, though,
contained two significant errors (front/rear strut templates were mislabeled,
and one dimension was typo'd), but this was easily corrected, and I've since
learned that this was caught by Fliskits and corrected.
The assembly consists of a lower section of 13mm tube with a permanent nose
cone, and an upper 13mm body with the chute. The two sections are joined by (3)
side tubes, which carry the ejection charge from the lower to upper body
through ducts cut in each of the tubes. Templates are provided to carefully cut
the ducts. Bonding the tubes straight, with ducts overlapping, is very tricky
and should not be rushed. Generous fillets are also in order, as the seams must
be completely air-tight.
Fins are a beautiful swept pattern, and cut from 1/16" balsa. The
leading edge is straight, but other lines have appealing curves and rounded
corners.
After construction of the tubes and fins, the instructions suggest painting
the rocket now, rather than mask off tiny details later. I went with two coats
of primer, followed by two coats of gloss white. It's worth noting that the
BT-2 side tubes had very pronounced spirals, much worse than any tube I've ever
gotten in a Fliskit. I wound up sanding down both coats of primer and applying
a heavy layer of Elmer's Fill N Finish to fill the spirals. This was very hard
to do on the completed assembly. I should have caught this earlier and filled
the spirals before bonding the tubes.
After painting, the real challenge to this kit comes into
play--construction of the tiny details. The first detail is a shroud, formed
from cardstock and an adhesive colored cover. The shroud fits snugly under the
fins, and is anchored to the body by 6 tiny struts. Next, frames for the 3
solar panels are built, and this is aided by construction of a jig (using the
provided templates and balsa stock). You must be very careful to measure and
bond EXACTLY per the templates or the panels will not fit properly. Due to the
typo on my template, I had to run to the hobby store to make replacement struts
(though Flis offered to replace my stock for free). The panels and frames are
bonded together, then carefully bonded to the rocket at notches in the fins and
to the tubes with drops of CA. Tweezers definitely help here, as you're working
with materials smaller than 1/16" square, and two of these share a notch
in a 1/16" fin.
I decided to use the full 16" chute provided rather than follow the
instructions and cut it down to 12", figuring the details were just
begging to break off on impact.
Finishing:
I had pre-painted the main body per the instructions, so "finishing"
involved hand-painting the struts and smaller details, and applying the
water-slide decals. Lots of decals. Lots of very small decals. I suspect the
decals came from Tango Papa, and were very high quality. Most impressive to me,
was the intricate details--these aren't just basic stripes. Even on the tiny
5mm tubes, you get decals clearly identifying this as the U.S.S Grissom, though
you're probably going to need a magnifying glass to read them. I actually ran
them under my son's 10X Intel Microscope, and could see clean, straight lines.
These decals are really high-resolution!

Flight:
The only recommended motor for this is the Estes A10-3. Flight prep is quick
and easy, as this needs no recovery wadding at all due to the ducted ejection
method. I'm a bit conservative, and put about 1" of "dog barf"
in the upper tube since plastic chutes seem to melt on their own on hot/humid
midwestern afternoons.
With winds of 6-8 mph, this weathercocked a bit, but flew very well and
straight as an arrow. The ejection was a bit early (would have been fine with
less wind), and the chute deployed without any problems.
The rocket came down just about right with the larger chute, and landed
less than 5 feet from a paved road in our field. Not a trace of damage, and 2
minutes later it was prepped for another flight. Same result, no problems. The
descent is fairly stable, so it tends to land on the end of the tube instead of
sideways, which saves the details from stress.
Recovery:
Nothing but pros on flight--easy to prep, doesn't need wadding, and I love the
fact that I get 4 A10's for the price of 3 A8-3's, so it's like getting the 4th
flight for free on this.

Summary:
While this is almost too beautiful to fly, it does fly very well, and the
fragile-looking details seem to be holding up well. It's one of the most
expensive FlisKits, but you get a lot of top-quality details and materials for
the money, and the result is a rocket any builder would be proud to include in
his fleet.
