Brief:
A skill level 1, Minimum Diameter, 4FNC (4 Fin & Nose Cone), Sport Model.
Construction:
This model kit comes in the usual Fliskits packaging; a clear plastic bag, with
eye-catching face-card, and transparent back, so parts can be clearly seen. As
usual, this product is individually numbered mine is #74.
The kit consists, mainly, of one high quality 228mm * 18mm card body tube,
a balsa nose cone, and a sheet of best quality 2mm balsa for the fins. In
addition, the kit consists of an 18-inch elastic shock cord, a nice long black
crepe streamer, a decal sheet, a fin pattern sheet, and the usual other bits
and bobs (launch lug, engine block etc.) Also of note, is a very good hints and
tips sheet that covers the usual Flight Preparation (in much clearer detail and
more depth than youd find in a Questes kit), and basic
construction skills such as tips on fin attachment.
The instructions are up to the high standards that are expected of
Fliskits.. They are VERY clear, contain clear diagrams; and, when combined with
the Hints and Tips sheet, cover every stage of construction and the techniques
needed for it.
As long as the instructions and hints are followed there are no
gotchas, even for a beginner. Everything fit perfectly, with the
exception of the nose cone, which required about 30 seconds of sanding to get
the fit I wanted (I like my nose cones to fit a little on the loose side). That
was personal preference, though; the original fit would have worked.
Actual construction was a breeze for somebody, like myself, whos
built a couple of LPR rocket kits previously. I imagine it would be
challenging, but straightforward, to somebody building their first kit. I built
it over the course of an evening whilst watching the telly, and chatting to a
couple of mates who'd popped round for some adult beverages.
The tools required are the very basic
ones. Eg: wood glue, model knife, pencil, sanding sealer, etc. All of which an
absolute beginner would find in a local Hobby/Craft Shop. The only thing an
absolute beginner might have trouble with is the expended engine needed to
insert the engine block.
Finishing:
Finishing is simple, and is greatly helped by the quality of the parts. The
balsa is very easy to fill and sand. The spirals on the body tube are virtually
non-existent; a couple of coats of primer, a bit of fine sanding, and
theyre gone!
The kit contains an idea for decoration on the face-card, however the
instructions tells you that this is only a suggestion, and to use your
imagination. I painted mine 'sunshine yellow' all over, and attached a couple
of the excellent decals. The decals, again, are a collection of ideas, leaving
the constructor to decide on their personal choice.
I finished off by spraying the whole thing in a couple of coats of clear.
Finishing took a few days, but I wanted to make sure that the coats were
dry before sanding and applying another. Im glad I did take the time, it
was worth it.

Flight:
Recommended motors are: A8-3, B6-4, and
C6-5. Armed with at least one of each, I went to launch on a lovely, almost
calm, summer evening after work.
First flight was on an A8-3. The rocket shot off the pad, gained some
serious air, and ejected at a perfect apogee. The generous streamer brought the
model down a couple of meters away from the pad. The whole flight was just
visible.
After re-prepping (very quick - 1 sheet of wadding; the streamer takes a
bit of rolling, but thats not difficult), it was ready for its second flight on
a B6-4. This didnt hang around. Within 1.5-seconds, the thing was well
out of sight. A few seconds passed, we heard the pop, and saw the large, black,
streamer open up. We were able to see the whole descent, and were able to
follow it into the next field. The recovery crew (my mate Derren, and his
Bike), were able to find it with no problem. An awesome flight, one of my all
time faves.
After the success of the last flight, the Flea was loaded with a C6-5. We
all stood back, as we knew this was going to be a fast one, and we wanted a
better angle to see it. Lucky we did as the Flea stripped a fin about 4m off
the pad, and went into a C powered corkscrew! Nobody was hurt or in any real
danger, as the puppy plunged into the ground (under power) about 6m away from
the nearest person and did that very sad, ground based ejection pop,
characteristic of a flight failure like this.
The lost fin was never found - how a bright yellow piece of balsa can go
missing in a field of freshly cut grass is beyond me!
Upon examination, it was quite obvious
that the fin joint was not strong enough. A fault which lies with me, and the
fact I only put one white glue fillet layer on each fin joint to save
weight instead of my usual 3+ layers.
Recovery:
The streamer included is superb. I got this kit to replace my Estes Viking,
which had suffered a RIP a few launches before (I only found the nosecone and
streamer, after a C launch). This streamer is at least twice the size of the
Vikings, and, being black, stands out more than the Vikings orange
one. The shock cord attaches to the inside of the body tube with the age-old
3-fold method. The other end is tied to the screw eye in the base of the nose
cone. A length of cotton is then tied to the screw eye, and the other end of
the cotton attached to the streamer. A simple system, but perfectly acceptable,
and effective enough. No damage was found in between the successful flights.

Summary:
This kit is a very good example of its type; a simple, minimum diameter, high
flying, sport rocket.
One of the main pros of this kit is its simplicity, and ease of build.
However, I would not recommend it to somebody who is a complete rocketry
novice, with no access to anybody who's built/flown a rocket before. In that
case I would recommend getting a Ready To Fly starter set; you get the
pad/controller, and a ready built rocket to learn how to fly with. If you've
got access to somebody who knows what they are doing, or have got few starter
set flights under your belt then this is the kit for you! It would be an ideal
kit for classroom/scout group situation.
There arent any real cons with the kit, the design is so simple, and
tried and tested, that theres nothing that can go wrong. The disaster I
had was of my own making, and Ive learned an important lesson from it:
Dont skimp on the fin attachment!
