(04/01/98) Apprehensive that it
was not a Estes' kit, skepticism was in the back of my mind, but it dissolved
quickly as I examined the components to the
Rogue Aerospace Hex
Courier. What I found first was a Nylon Parachute.You mean I don't have
to cut one out of a plastic sheet and attach shroud lines? Next a piece of
Kevlar® Shock Cord. Next six that had alignment lines already drawn on
them. And Perma-Wadding to eliminate the need of tissue wadding. Needless to
say, first impressions were very good. The written
instructions where clear and allowed for easy assembly. They lacked a few
helpful illustrations, however, I have come to understand that Rogue is doing a
re-write to make them even easier to follow. No special tools were needed.

my Rocket Comparison Page
During assembly, I took the opportunity to try a new glue
called Quick Grab. It promises to be crystal clear, waterproof and paintable.
It was. It was. It also claimed to be fast drying, 40 second grab with light
load support after 10 minutes and full load after 24 hours. It did this, too.
It did this, too. In fact, the only problem with the glue is that it gets a
skin quick and therefore has "stringers" of glue that you have to
control. It did well on fillets and in attaching the tube fins, however it is
very thick so it didn't do as well when gluing motor blocks or centering rings.
I would still recommend it for smaller models (A - D motors) since it gives you
fast drying time and is much cheaper than CA. That being said, Rogue recommends
CA or white glue.
Assembly was straight forward and relatively quick. I
would suggest that once you test fit your first tube fin, you mark the tube all
the way around to allow to line up the tops evenly. Also, be sure to continue
the line around the edge on each of the tubes so that all the slants line up
and look correct. Using a fast drying glue is best while attaching the tube
fins, because you will most likely have to hold them in place until they
"grab". Using masking tape could help hold them in place while
drying, however, avoid a rubber band because it has a tendency to rotate the
tubes at high tension points of the rubber band.
If the kit is subject to damage it would be the bottom
tips of the tube fins. In my opinion, these tube fins are not any more
susceptible to damage than regular balsa fins so strengthening them by coating
them with CA or epoxy would just make good sense.
The shock cord is mounted to the
motor mount and is strung to attach to the nose cone,
parachute and Perma-Wadding. The nose cone is balsa. Be sure to seal the nose
cone with CA, epoxy or balsa sealer. I had to do a little sanding on the
shoulder of my nose cone to make it fit into the body tube (no big deal).
With the quality of the recovery system, Nylon chute,
Kevlar® shock cord, and Perma-Wadding, I would have liked to see a swivel added
for attachment. It would have been the icing on the cake.
Finishing the model was unique too. I wanted to simulate
the picture by making the "high-thrust magneto-impulse engines" stand
out. Therefore, I choose red for the inside since I believe when
"magneto-impulse engines" get running at full
capacity, they heat the surrounding metal as it's
structural integrity is compromised due to the incredible forces of inter-space
travel through "hostile territory". To do this, I shielded as much of
the existing rocket as possible and took several passes at spraying the paint
right inside the tubes. Unfortunately, I also wanted the bottom of the body
tube red and didn't shield the inside of the motor mount. Be sure to do that or
enjoy a new definition of "friction fit". I
choose white for the outside and a silver nose cone.
The Hex Courier came with a nice
water-transfer decal sheet giving you the ability to match the picture on the
instructions or to spell out something on you own. The transfer sheet had two
of every letter and four of every number that could be placed together to spell
something. I chose to go away from the example and spelled out Hex
Courier. The decal sheet has the decals for it to say "United States
Courier Corps".
Prepping the model for flight is great because you simple
slide the Perma-Wadding into the tube, fold and wrap the chute, push in and top
it off with the nose cone. Then add your motor. Fast and easy.
At a local club's sport launch we prepared to fly. After
receiving two nice comments carrying the model to the launch area we were ready
to go with an A8-3. Three, two, one . . . whoosh! Hmmmm. Hmmmm. One complete
loop, a perfect ejection and back to the ground with no damage. Tried again
with a C6-5 and this time got two complete loops. Definitely unstable.
After a day or so, I added some weight to the nose cone
and tried again with a C6-5. This time a perfectly straight flight . . .
beautiful!
It is important to note that
Rogue Aerospace gets a 5 star for
how they have handled this situation. They have sent a letter to all those that
had previously purchased the Hex Courier and explained that there may
be a stability problem. They offered them a replacement kit with shorter tube
fins, or told them how much to shorten them and provided a gift certificate for
any trouble. This is excellent customer service!
Due to my experiences, this kit rates a
3
1/2 points, but despite the stability problem of my model, future Hex
Courier's have been modified to be stable and therefore these new kits will
no doubt be a 4+. I would recommend that you give
Rogue Aerospace's Hex
Courier a mission of your own.
