| (11/27/04) After flying a number of Art Applewhite's
kits on 13mm - 24mm, I have moved up one notch to a Stealth 29mm. Will I fly
this in my front yard? No, but I'm expecting the same fun, low altitude
performance as I have had with the other variations.
The Stealth design is actually shared in many
ways with the
Qubit
and
Scimitar.
The Qubit has a straight lower edgy, the Scimitar has a half-moon lower edge
and the Stealth as a saw-tooth edge. The Stealth comes in a few colors, but why
would anyone get anything other than black? After all, it is the
"Stealth".
The kit includes the instructions, a 29mm motor mount
tube, a cardstock template for three sides that are made of 1/4"
foamboard, and lastly a single triangle piece of foamboard for the bottom of
the rocket.
CONSTRUCTION:
The instructions are printed on 3 pages of
8½ x 11" paper. They are photo-illustrated which makes the easy to
build rocket, even easier!
The major steps include cutting out the
template and marking the three sides. Then, the three sides are cut per the
instructions using a hobby knife. Use a NEW blade for this task.
The three sides are glued together with
Elmer's Glue All (I used Elmer's White Glue).
The bottom is pre-marked for the launch rod
hole and motor tube hole. Cut these out then glue the bottom into place.
The motor tube is glued into place.
Done!
Overall, for CONSTRUCTION I
would rate this kit
5
points. Simple with good instructions.
FLIGHT/RECOVERY:
Art Applewhite recommends the "Ellis
Mountain G35 or any 29mm single use motor or Aerotech RMS-29/40-120
reload."
Art Applewhite warns, "Do not use a
motor with the ejection charge installed as this will melt and burn the
foamboard and eject the motor."
Art Applewhite indicates the Stealth should
weigh 2.3 ounces. My Stealth weighed 2.2 ounces.
I decided to fly it for the first time on an EconoJet
F20-4. I took off the paper cap and poured the BP into my BP bottle for use in
another charge. I then tapped the motor to ensure all BP was out. I made a
small thrust ring with about 3 wraps of masking tape and friction fit it into
the motor tube.
I was alone, so I tried to set up to take a
picture at the same time as I pressed the launch button. Whoa! Didn't expect
that. Missed the photo completely.
The loudness of the F20 was great, but only seemed
exaggerated by the design of the Stealth (is that possible). The Stealth
exploded off the pad, then on the way up (straight) started a spinning motion.
Lots of smoke as it tipped over and headed for the ground. Upon inspection the
tip of the rocket is slightly crushed.
My second flight was on an Ellis G35-6 with
the BP removed. Got this one on the camera! Very, very, cool! The G35 just kept
pushing the rocket upward. Nice long burn. At the top, it too turned over in a
lot of delay smoke. Recovered very close to the pad!
For FLIGHT/RECOVERY, I would
rate this rocket
4
½ points. Awesome flights which allow F and G motors to be used in
much smaller fields! Don't know what to do about the tip damage though. Maybe
it should be filled with clay or epoxy.
I give the rocket an OVERALL rating of
4
½ points. I have had a good experience with every one of Art
Applewhite's kits. They are a unique niche in rocketry and can allow higher
powered motors in smaller fields. They would make great demo or school project
rockets as well! Go for it!
