(03/19/02) I started enjoying the Quest MicroMaxx system recently and wanted
to check out another company's kits. Well, there are (were) only two that had
any kits. Nano Rockets and Aerospace Speciality Products (ASP). I purchased the
Micro WAC Corporal with Tiny Tim Booster and the Micro Jayhawk from ASP to
build on a winter vacation. Once received, I was pleased to see that even
though these are "micro" kits they are in no way "micro" in
quality. In fact, the ASP kit parts and instructions are of higher quality than
a number of other "standard" kits that I have put together. So,
needless to say, at first glance I was impressed.
The Micro WAC Corporal with Tiny Tim Booster included 2 body
tubes, a regular tube coupler, a clear tube coupler, styrene fin stock, 2 sizes
of styrene half-round, styrene launch lug and offset, a wood nose cone, lead
weight, a Kevlar®
shock cord, 2 mylar streamers and a decal set.
CONSTRUCTION:
The instructions are on 4 pages of 8.5 x 11" paper
and include illustrations as well as cutting and alignment guides. They are
clear and thorough instructions telling the modeler exactly how to be
successful in building and flying this rocket.
After sanding the outside of the body tubes to get the
shine off, they are marked using a cut-out marking guide and a provided styrene
angle. The styrene angle is a nice little provision for marking the tubes, but
I found mine not quite rigid enough as I ran the pencil up along the edge. It
was functional though and if care is taken would provide the functionality
necessary.
The fins are cut out using fin cutting guides. It is
recommended to use double-sided tape to keep the guide attached to the styrene
strips. ASP keeps with their intentions of having "detail accurate"
kits, even in the Micro scale as the instructions give direction in the
rounding the correct corners on the fins. The styrene material is also nice as
it doesn't make the fins too thick in relation to the size of the rocket. On
the other hand, this thin material that is cut into small tiny fins takes some
effort (and patience) to work with. The instructions suggest having a pair of
tweezers. You'll want to use CA (as recommended) while assembling this kit. The
faster the drying time the better as long as you are accurate in your
placement.
The paper coupler is cut in half and used to hold the
split lead shot with the Kevlar®
shockcord tied to it in place in the upper-most part of the body tube. The nose
cone is glued into place. The rocket's separation point is between the booster
and .
One of the styrene half-rounds is used as the detail of
the conduit on the side of the WAC Corporal. You are instructed to cut it to
size and somehow I missed that and used the piece at the length provided. I'd
lose in a scale competition.
After the rocket is mostly assembled but still in two
separate pieces (booster and sustainer), ASP suggests some finishing activity.
This is important as the clear coupler is still not installed. This is to
protect it from any finishing activity so that it doesn't get messed up. Having
it clear is to simulate the absence of a coupler here.
With respect to this clear coupler, you are instructed to
"drill" a hole in the top-side of it with a hobby knife. Then you
groove a channel from the hole to the top of the clear coupler where the
Kevlar®
shockcord will sit. The Kevlar®
shockcord is then tied to the clear coupler, in effect connecting the sustainer
to the booster. The opposite end of the clear coupler is glued into the
booster. It serves as the motor thrust ring as well. Then for the most tedious
assembly step, gluing the smaller half-rounds onto the clear tube. Oh, what fun
that was!
In my case, I finished assembly prior to doing any
painting. I hand painted mine with Testors Model paint and a brush. It turned
out okay (to me). I didn't apply any of the provided decals. All-in-all, I'm
happy with the final looks of this rocket.
Overall, for CONSTRUCTION I would rate
this kit 4 ½ points. Instructions were outstanding. Detail was
outstanding. Material was outstanding. My only complaint (same as for most high
power kits) is motor retention. Quest does it with a twist clip. I've done it
with a paper clip. I can't wait to see someone do it some other way.
FLIGHT/RECOVERY:
Before I write about my flight experience I should say
that I did not attach the provided streamer. I just can't get into shoving a
streamer into such a tiny tube. And besides all my Quest kits would destroy the
streamer after just a couple of flights. ASP instructs that you can get the
streamer in there and then also a couple of small "loosely wadded"
flame proof wadding to protect it. ASP also provides a second streamer for when
the first one wears out. I probably should have followed this instruction as
you will see.
The first flight was nice and impressive, probably
getting to 50 feet (and that's all you want for a rocket this size). Upon
descent though it fell fast (remember I'm the one that didn't put in the
streamer) as the sustainer lead the way in a stable straight down descent. This
is no doubt due to the lead weight in the upper section of the body
tube.
The second flight was also perfectly straight and about the same
altitude. The ejection popped which kicked the motor and the rocket didn't
separate. Now more so than the first flight it came in "hot". The
fall was broken by icy snow which compressed the booster into the sustainer a
bit. I'm thinking the fit of the clear tube with the Kevlar®
shockcord on the side made the top on too tight. At the same time the motor
might not have been in as "fictionally" tight as the first flight so
the kicked the least resistive piece. Motor retention could
have stopped this.
I will humbly be adding the streamer for future flights
and look forward to seeing its descent then.
For FLIGHT/RECOVERY, I would rate this kit 5 points. Not taking anything away for me not using the
streamer. The design is excellent and the use of Kevlar®
will hold up. I have a lot of confidence in the recovery system connections and
they don't show on the outside of the rocket. The rocket was stable as it flew
very straight. The nose cone is wood and didn't show any damage as it landed on
the ground the first time and the icy snow the second time.

(Note: this picture was taken after the second flight)
Overall, the Micro WAC Corporal with Tiny Tim Booster is
an excellent scale kit to fly in your backyard with MicroMaxx motors. I
performs as good as any of the Quest pre-built rockets. The fin thickness makes
it realistic in its size (proportions). It only loses some because of the
of the motors, but in contrast with other kits, it has a thrust
ring (the clear coupler). I believe that a motor retention clip is possible and
that is should be implemented. I give the kit an OVERALL rating of 5 points.
Also for you fans of the WAC Corporal, ASP offers this
MicroMaxx version as well as an 18mm, 24mm and 29mm version of this sounding
missile.
