(04/22/02) My new ASP Micro Jayhawk
has officially become my smallest rocket that I have ever built and flown. It
is only 3.75" tall and 0.282" in diameter. Wow!
I've enjoyed these little Quest motor rockets
since I can fly them in our yard. But not only that, it is rather interesting
to make something this small fly. The only thing smaller that I have ever flown
was a "match rocket".
I purchased the Micro Jayhawk along with the
Micro
WAC Corporal with Tiny Tim from ASP to build on a winter vacation.
Notice the size difference between those two kits. 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. I was impressed.
The Micro Jayhawk included 2 body tubes, 2 tube couplers,
styrene fin stock, styrene half-round, styrene , a wood nose cone, 2
sizes of lead weight, a ®
, and a decal set.
CONSTRUCTION:
The instructions are on 5 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. I found the marking guide to be missing "Tick Marks" which
the instructions say should line up.
The various 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. There are three different pieces of styrene fin material and
different thickness. You are to cut the main fins, main fin tips, and leading
fins from the various pieces. The styrene material is nice as it doesn't make
the fins too thick in relation to the size of the rocket, but get your tweezers
out to work with this stuff. Definitely follow the instructions and us for
the faster setting time.
Like the WAC Corporal, the paper is cut to size
and is then used to hold both split lead shots with the Kevlar®
shockcord tied to the bigger one in place in the upper-most part of the body
tube. The is glued into place. The coupler sticks out of this upper
body tube as the coupler for attaching the bottom section.
The lower connection of the Kevlar®
shockcord is made by tying it to the remaining small piece (1/8") of cut
coupler. This is then slid into the top of the bottom body tube and pushed down
until it is 3/4" from the bottom. The 3/4" is set by using the second
coupler. Once in place you drop in a couple of drops of CA and voila' you now
have a ! I love it!
ASP instructions are thorough, but I already said that.
Here they point to the fact that there is some finishing work that needs to be
completed before finishing the rocket assembly. Read carefully and you will be
successful.
One of the final assembly actions is attaching the nose
fins. You carefully cut a slit in the wooden nose cone and then attach the nose
fins to it.
After that the launch lug is glued onto one of the main
(-type) fins and it is ready to finish.
I hand
painted mine with Testors Model paint and a brush. I was okay with the finish,
but you can see that it could be done much better if you took your time and
followed the instructions. I didn't paint the nose tip black nor did I apply
any of the provided water-transfer decals.
Overall, for CONSTRUCTION I would rate
this kit 4
points. As with the WAC Corporal, the instructions, detail and material
are outstanding. The paper needs to have "Tick Marks". The
same complaint exists, too; and that 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:
The Jayhawk did not come with a like the WAC
Corporal. I can't imagine being able to get it into the upper tube any
way!
The first
flight zipped off the pad. I didn't actually see it until after the pop of
ejection. Then it separated and fell fine. The motor kicked at ejection too and
fell on the driveway next to me. Remember they are hot so don't rush over and
pick them up! (no, I didn't)
The second flight was straight and fast. The rocket is so
small that you should have help for spotting. I had my son helping and we
recovered this one too.
For FLIGHT/RECOVERY, I would rate this kit 5
points. The use of Kevlar® is
nice to hold up against the ejection charges. The attachment is nice with no
outside connections made. The rocket appeared to be stable. I didn't see it
fly, just know that it went straight up from the launcher based on where I saw
it eject.
Overall, the Jayhawk is an excellent scale kit to fly in
your backyard with MicroMaxx motors. It is fast off the pad but still
trackable. The fin thickness makes it realistic in its size (proportions). It
only loses some because of a slight mistake with the template and the friction
fit of the motors, but in contrast with other kits, it has a thrust ring. I
believe that a motor retention clip is possible and that is should be
implemented. I give the kit an OVERALL rating of 4 ½
points.

Brief:
A beautiful micro scale (46.1:1) of the Navy's Jayhawk missile. Very affordable
($7.50), flies cheaply, and packs enough detail to be a respectable peanut
sport scale contestant.
Construction:
The kit contains:
- 2 7mm body tubes
- 2 tube couplers (1 serves as motor block)
- Styrene fin stock
- Styrene trim pieces (half round, standoff)
- Styrene launch lug
- Hardwood nose cone
- Lead shot
- Kevlar®
shock cord
- Waterslide decal
Instructions were well written and easy to follow but tend to be a bit light
on illustrations. This build is very much like a standard skill level 2 rocket
with fins cut from stock and masked paint pattern, but I'd rate it a skill
level 3 due to the challenge of working on such a small scale. Plus styrene is
a little harder to work with than balsa.
Construction starts with sanding and marking the body tube. A styrene angle
is provided for use as a marking tool in case you don't have any doorjambs that
would work on a 7mm tube.
Fins are cut from assorted stock. There are two lower fins, two upper fins,
and two "wings" or stabilizers bonded to the tip edges of the lower
fins. The instructions suggest using two-sided tape to tack the styrene stock
in place while tracing and cutting, which is a very good idea. I scored the
stock using a sharp #11 X-Acto blade, then folded along the score line until
the seam cracked. I then rounded the leading and trailing edges. All styrene
was glued and filleted using Plasti-zap CA. Tacking the upper fins to the wood
nose cone was very tricky and I cut small slots in the nose to hold the fins in
place while doing this.
The
next phase of assembly is the construction of the weighted . To make
this, you tie the Kevlar®
cord into a knot, which slips through a slot in the lead sinker and catches.
The weight is then glued and wedged into the tube coupler, which is glued into
the upper body tube. The other end of the Kevlar®
is tied around a small section of coupler. This coupler is glued to the lower
body tube to also act as a motor block.
Construction wraps up with making a styrene conduit, which runs along one
side of the body tube. This conduit needs to be cut at the seam of the two body
tubes.
Finishing:
Painting this one isn't too bad. After a couple of coats of white and
Elmer's Fill 'n' Finish to fill the tubes , I applied two coats of alert
orange. I allowed the orange to cure for a full 3 days then masked off all but
the upper half of the nose for a gloss black accent.
There are some amazingly detailed water-slide decals provided with this
kit, but you'll need a magnifying glass and tweezers to apply them accurately.
Navy star/ patterns, missile identity marks, stripes, everything is barely
large enough to read. It's worth the work though, as this is a beautiful
missile when finished with proper care.
Construction Rating:
4
½ out of 5
Flight:
There's zero variety in the MicroMaxx motor world--you get the same motors
as everyone else and the same delay (less than a second usually) as everyone
else. Still, it's a great thrust/weight ratio and it's always a kick to see the
kids shock when they see such a tiny rocket zip at such high speeds beyond
typical sight range.
This one flew wonderfully, kicking off the pad on the first try (I have a
lot of trouble getting MMXs to light right away, even when using a 12V system).
As usual, I could not see the or notice the apogee but did pick up
a cloud of smoke when it ejected and followed the back to
earth.
I managed to land on the driveway adjacent to the field, causing one wing
tip to break off. It will be easily repaired.
Recovery:
PROs: affordable motors, pretty good for a MMX.
CONs: no room for a streamer, definitely needs to fly over grass.
Flight Rating:
4
½ out of 5
Summary:
This is one of my favorite MicroMaxx rockets although I hate to call it
MicroMaxx for fear it would be associated with the junk that's all over the
hobby stores out there. This is a very high quality kit, painstakingly
detailed, and a terrific value.
PROs: incredible detail, great looking missile
CONs: micro scale is challenging to build
Overall Rating:
