Brief:
Stylish 3FNC (3 fin and nose cone) rocket from Canadian manufacturers Sunward
Model Aerospace.
Construction:
The Kit comes in a transparent plastic bag, sporting a VERY colorful face card.
The kit contains:
- 1 45cm BT56 Body Tube
- 1 Plastic Nose cone (the same cone used in all Sunward kits, it seems)
- 2 Engine Centering Rings
- 1 Engine Block
- 1 18mm Engine Tube
- 1 Parachute (unassembled)
- 1 Engine Hook
- 1 Rubber Shock Cord
- 1 Fin Reinforcement Tabs
- 1 Launch Lug
- 1 Sheet of Laser Cut Fins
- 1 Decal Sheet
The usual paraphernalia (glue, knife, sandpaper, paint, etc.) is also
required.
The rocket comes with instructions written in both English & French.
They are very clear and anybody who's built an Estes level 1 kit (e.g. Big
Bertha) would have no problem in assembling this kit. The components are all of
exceptional quality but not the usual "run of the mill" components
found in most kits nowadays. The Engine Centering Rings are much bulkier than
usual. The Engine Hook is a threaded L-shaped piece of metal rather like a
simple domestic picture hook. The Nose cone is made of High
Polyethylene and the parachute is made of a much higher quality plastic than
the usual "Happy Shopper carrier bag" plastic chutes.
I
had three main concerns with the components. Firstly I was a little worried
about the loose fit of the Engine Centering Rings, inside the main body tube.
Looking on Sunward's website, I found that the Centering Rings are designed to
soak up some of the glue and expand. This they did so this fear was unfounded.
The second worry I had was the Rubber material used for the shock cord. As I
was determined to build the model stock, I used the supplied cord but took the
precaution of installing a Nomex®
heat shield to compliment the recovery wadding.
The final issue I have with this kit, is the balsa fins. Although the balsa
used is of tip-top quality, the design of the fins makes them far too fragile.
Perhaps making them out of a light ply, would have been a better idea. If I was
to build this kit again, I would definitely reinforce the fins.
One technique used in this kit which I have not come across
before is the use of card tabs to reinforce the fin/body joint (as opposed to
glue fillets). Not sure I like this method but as I've only built one kit
utilizing this method, I'm reserving judgment. They do seem to be doing their
job.
The Engine Centering Rings come with pre-drilled holes for inserting the
Engine Hook. Again, I was determined to build the kit stock but the unused hole
in the fore ring was just too tempting! I Quest-ified the rocket by threading a
piece of Kevlar®
cord through the hole, and securing it to the back of the ring with a small
blob of 5min epoxy. I then tied the main shock cord to this instead of
attaching it to the inside of the body tube using the described
in the instructions.
Finishing:
Painting this bird was a doddle. The balsa and tube spirals needed almost no
filling. There is a HUGE gotcha with painting this rocket and that's the nose
cone. You MUST give it a thorough sanding with fine sandpaper before
priming/painting or the paint stands a very good chance of peeling off. This is
not in the instructions and it really needs to be there to save somebody from
ruining a paint job. I gave mine a good sanding and have had no trouble at all
with paint peeling.
The face card artwork suggests painting the rocket pink and black. I'm not
the worlds greatest fan of pink so I went for orange instead.

Flight:
The first flight was on a B6-4 on a day with a very light breeze. The rocket
went a lot lower than I expected but looked really cool. I like low, slow
rockets This one is a beauty. The chute is a bit excessive and the rocket
drifted into the next field. It does need that chute with those fragile fins
though.
Second flight I angled it more into the wind and the bird touched down
about 10 meters away from the pad after another majestic flight. No damage or
wear to be found in either the fins or shock cord.
A week later I went out to try it on C6-5s but brought along a box of B6-4s
again by mistake! I decided to launch anyway. The first flight of the day was
essentially a repeat of the second flight in the previous session. I decided to
launch just once more so I could see how the shock cord will hold up. I had
been impressed by how the thing was holding out--no wear at all whereas a
'usual' cord is normally showing the first signs of wear after about 3 or 4
launches.
At ejection on the fourth flight, the nose cone/parachute separated from
the shock cord/body. The main body hit the ground with a thump and the nose
cone/chute drifted off. Luckily, the nose cone was heavy enough to bring the
chute down within the field so that was retrieved. The fin on which the main
body landed, broke cleanly along the grain and I was able to effect a repair on
the spot using CYA. It turns out that the shock cord managed to untie itself
from it's attachment point on the nose cone.
Later, I noticed that the damaged fin was slightly wobbly. The main glue
joint between the fin and the tube must have broken but the fin tabs were
keeping the fin in place. A little CYA should put this right.

Summary:
This is a very good kit and considering it only costs £11, it is
exceptional value for money. The bat styling is very cool and should appeal to
Gothic-types and people looking for something different. It would be perfect
for a Halloween launch, natch.
The kit is easy enough for a beginner with a little experience to build:
the unusual components and the possibilities of improving the kit (such as
the fins) makes this an interesting kit for a more experienced
builder.
The reservations I had over the shock cord have turned out to be unfounded.
In fact, this shock cord seems to be superior to usual. The recovery failure
was down to the cord coming untied, not snapping or burning through.
On the strength of this kit, I'm certainly going to try other models by
Sunward.

Brief:
- Single-stage 3FNC with cool bat wings.
- Length: 24.5"
- Diameter: 1.3"
My daughter won this kit, donated by Sunward, in an EMRR Virtual Contest.
Dan Westley has already written a very good review of this kit, so we're just
going to cover the areas that were different for us.
Construction:
Materials: Dan has a comprehensive parts list, so I won't repeat it
here. The Moondance uses the same nose cone with a bubble canopy that is used
on all the Sunward "fighter-jet" kits. It's great on the fighters,
but looks a little out of place on this kit.
The 18" blue and white parachute is made from a very durable plastic,
thicker than standard Estes chutes. The shroud lines are also much stronger
than normal.
The engine mount uses the same L-screw engine hook that Sunward uses on all
their kits. It is strong enough to hold the engine firmly in place during
ejection, but easily pivots out of the way when replacing engines.
The balsa fins with the bat wing shape are what really make this kit unique.
The laser cutting was very well done, and the parts popped cleanly from the
sheet with minimal sanding required. The balsa quality was very good, but
awfully thin. I was concerned about the fragility of the fins, and my concerns
turned out to be well founded. The sharp points on the fins will dig into soft
materials (like seat cushions). I found this out when I split a fin lengthwise
while loading the car after a day of flying. Easily repaired with CA, but
thicker balsa or some other method of reinforcement should be considered.

Assembly: The directions are very straight-forward and a beginner
should have little problems. Like Dan, we also used the Quest-style method of
attaching a Kevlar shock cord anchor through the front hole in the engine mount
and securing it with 5-minute epoxy. We also used 5-minute epoxy to install the
engine mount in the body. It worked very well.
I have seen plain rubber shock cords crumble to dust as they age, so instead
we used 1/4" elastic, twice as wide as standard Estes cord. I tied it to
the Kevlar anchor cord with a double sheet bend knot, which is ideal when one
cord is much thicker than the other.
The instructions called for the shock cord and the parachute shroud lines to
all be inserted through a small hole in the base of the nose cone. I was afraid
that enlarging the hole enough to fit all that would make the surrounding
material too weak, so I tied a loop in the shock cord and attached the
parachute with a large snap swivel. This also gives the nose some shock
protection when the chute snaps open, and reduces the chance of separation.
Finishing:
The cover art shows a purplish color for the body, but this kit just begs to
be painted Halloween pumpkin orange. We used two coats of Rustoleum Painter's
Choice Real Orange. The spirals on the tube were so light we did not even
bother to fill them.

The nose cone was
painted with two coats of Rustoleum Painter's Choice Green to complete the
pumpkin motif. Before painting, we wet-sanded it with wet/dry sandpaper, then
let it dry for a day.
Fins were painted with two coats of Zynolyte Spray-Mate brand gloss black
paint. I hate this stuff! I stocked up when it was on sale for 99 cents per
can, and I can't wait to get rid of the last of it. It looks fine, but the
smell is awful. We painted the fins outdoors and brought them inside after they
were dry, but they still stunk several days later.

I find it a lot
easier to get a good crisp color seam by painting the body and fins separately
before attaching them. To do so, I attach a wide piece of masking tape to a
board sticky-side up and stick the fins to that. After the paint dries, just
peel off the fins, rough up the with sandpaper and epoxy them to the
body tube. We used an Estes fin alignment guide to hold the fin in place while
the 5-minute epoxy dried. We did not use the reinforcing tabs supplied with the
kit.
Decals are peel-and-press, and are of good quality. The glaring eyes on the
nose cone combine with the bat wings to give a menacing look. The background is
white but the edges are clear, so any base paint color will work without
the stickers microscopically close.

Flight:
The
manufacturer's recommend engine list is a bit confusing. The list on the cover
art says B6-2(first flight), B6-4, C5-3, C6-5, and C6-7. The instruction sheet
says B6-2(first flight), B6-4, B8-5, and C6-5. The web site says "B6-4 to
C6-7 single stage engines".
My daughter has never had a rocket last more than 3 flights without either
vanishing (Mosquito on a 1/4A) or drifting away (Viking on a B6), so she was
very paranoid about losing another one. The Moondance is far bigger and heavier
than those others and the nearest trees were at least 3 blocks away, but she
still wouldn't let me load anything bigger than a B.
For the maiden flight we used a B4-4. Engine installation was very quick
with a simple twist of the L-shaped hook.
The breeze was about 5-10 mph, so we tilted the rod about 10 degrees into
the wind. Nice slow liftoff, angling into the wind. Parachute opened just past
apogee. The rocket descended gently, with minimal spinning or swinging, and
came right back to us. It landed gently in the grass about 4 feet to the right
of the pad. Perfect flight!
With four sheets of the Estes wadding stuffed down in the body and one sheet
wrapped around the chute, we still got a small scorch on the chute.
I couldn't talk her into flying it any more that day. What a chicken!

Summary:
This is a very nice kit with cool bat fins and decals.
After seeing this kit, I am eager to try one of Sunward's more challenging
fighter-style kits.
Pros: Distinctive appearance with bat-wing fins.
Cons: Fins snag and break easily.
