06/27/06) Brief:
Pimp Daddy's A-20 Demon is a dead ringer for the original Estes kit with all of
the appropriate decals, the 24mm power, and the payload section that you'll
remember from the original. While it is only a simple project, you wind up
with a rocket that's as long on looks as it is on performance. The kit is a
dead stock of the original and comes packaged in a traditional bag with
hang tag, which only adds to the vintage experience.
Construction:
The parts list:
- BT-55 main body tube
- BT-55S payload tube
- BT-50J engine tube
- NB-55 balsa bulkhead
- BNC-55AM balsa nose cone
- Pre-cut balsa fins
- Decals
- 18" Mylar parachute
- 1/4" sewing elastic shock cord
- Medium
- EH-2 engine hook
- AR-2050 engine block
- 2 AR-5055 centering rings
- LL-2A launch lug
The instructions for this kit are an actual copy of the original Estes kit,
so there's nothing resembling a "gotcha". To be honest, the only
thing I used the instructions for was decal placement. (This is obviously true
if you look at my fin placement. Oops.) Everything about the build is pretty
much instinctive if you've had previous experience building Estes kits of this
era. Construction involved shaping the edges of the fins, installing the balsa
bulkhead in the bottom of the payload section, and assembling and installing
the engine mount. I went off the board here and tied a long piece of 250#
Kevlar®
cord around the engine mount, then ran it under the forward centering ring.
It's not that I don't trust the suggested Estes-style paper mount, I just think
that a kit of this quality deserves a recovery system that's as up to date as
possible. (Nostalgia only goes so far.)
Finishing:
Finishing was a simple matter of applying thinned Elmer's Fill 'n' Finish to
the body tubes, nose cone, and fins. After sanding, I primed the whole rocket
with Valspar white primer, then sprayed everything but the nose cone with
Valspar Bumblebee Gloss. The nose cone and payload section were then painted
with Valspar gloss white, while a single fin was masked off and painted Valspar
gloss black. Once the paint had cured for several weeks (as we got rained out
one week), I applied the decals, which were a pleasure all to themselves. Pimp
Daddy had recently switched to an Alps printer and decal application is a
simple matter of lining everything up correctly. The foil stickers are like any
stickers you've ever worked with except they are better looking. Best results
are obtained by taking your time, especially with the big wrap sticker that
covers the payload section. I had to trim mine ever so slightly to keep from
having a bit of overhang, but other than that I was very pleased with the ease
with which it applied. The best way is the way the directions say to apply it:
draw a straight line on the payload section, line up the sticker, and roll it
slowly. The rivet details for the fins should be first bent on the
center line then placed gently into the fillet area, taking care to line each
up with the previous one. (Starting at the back of the rocket can also help to
hide your first rather clumsy attempts from all but the most discerning eyes.)
The finished product is almost too cool

Flight:
Rockets like this are likely what will keep me from ever venturing any closer
to high power than the occasional F (and only because I already have two
rockets that call for a motor of that size, and both happened to be gifts). The
A-20 Demon truly screams off the pad on a D-12, looks great doing it, and
doesn't come close to over flying the field at the VOA. Both flights to date
have been on relatively calm days and were impressive in their speed off the
pad, dead straight flight paths, and altitude. For the first flight, the Demon
was painted but without applying the decals. For the second flight, I had not
only found time to finish the decals but also to refurbish my battered clones
of the other rockets that were displayed on the
1977
Estes catalog page with the Demon. Also on the that day were a
Thrustline Cherokee D, an Estes Sky Raider, and an Estes Renegade, all of which
had flown previously and all of which had suffered some kind of damage. It was
a very cool theme launch, one that I'd like to do in the future with the
Mini-Brute page.
Recovery:
I used an extra long piece of Kevlar®
and elastic to lessen the potential "shock" on the rocket at
ejection. This seemed to work well as the ejection looked to be fairly gentle
from our vantage point on the flight line. There were a few muttered
"separation" comments from some of the others as the body tube looked
like it was falling away from the parachute. The shock cord did its job though
and everything came back in perfect shape on the Mylar chute. I hadn't
previously been a big fan of Mylar, but lately I've allowed myself to be won
back over.
Flight Rating:

Summary:
PROs: Awesome looks and performance. A dead on replica of a classic Estes kit,
right down to the hang tag.
CONs: Lack of Kevlar®
in the recovery system (but I had my own).
