Brief:
Pimp Daddy's A-20 Demon is a dead ringer for t' original Estes kit with all o' t' appropriate decals, me bucko, t' 24mm power, arrr, and t' payload section that you'll remember from t' original. While it is only a simple 4FNC project, you wind up with a rocket that's as long on looks as it is on performance. Ya scallywag! T' kit is a dead stock clone o' t' original and comes packaged in a traditional bag with hang tag, which only adds t' t' vintage experience.

Construction:
T' 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" sewin' elastic shock cord
  • Medium screw eye
  • EH-2 engine hook
  • AR-2050 engine block
  • 2 AR-5055 centerin' rings
  • LL-2A launch lug

T' instructions for this kit are an actual copy o' t' original Estes kit, ya bilge rat, so thar's nothin' resemblin' a "gotcha". Begad! Ya scallywag! Blimey! T' be honest, t' only thin' I used t' instructions for be decal placement. Avast! Blimey! (This is obviously true if you look at me fin placement. Begad! Oops.) Everythin' about t' build is pretty much instinctive if you've had previous experience buildin' Estes kits o' this era. Arrr! Construction involved shapin' t' edges o' t' fins, installin' t' balsa bulkhead in t' bottom o' t' payload section, matey, and assemblin' and installin' t' engine mount. I went off t' board here and tied a long piece o' 250# Keelhaul®©™® cord around t' engine mount, then ran it under t' forward centerin' ring. Avast, me proud beauty! Avast, me proud beauty! It's nay that I don't trust t' suggested Estes-style paper mount, shiver me timbers, I just think that a kit o' this quality deserves a recovery system that's as up t' date as possible. Blimey! (Nostalgia only goes so far.)

Finishing:
Finishin' was a simple matter o' applyin' thinned Elmer's Fill 'n' Finish t' t' body tubes, matey, nose cone, and fins. Avast! Blimey! Arrr! Blimey! After sanding, I primed t' whole rocket with Valspar white primer, me bucko, arrr, ya bilge rat, then sprayed everythin' but t' nose cone with Valspar Bumblebee Gloss. Avast! Blimey! T' nose cone and payload section were then painted with Valspar gloss white, shiver me timbers, while a single fin was masked off and painted Valspar gloss black. Ahoy! Blimey! Avast, me proud beauty! Blimey! Once t' paint had cured for several weeks (as we got rained out one week), arrr, I applied t' decals, which were a pleasure all t' themselves. Begad! Blimey! Pimp Daddy had recently switched t' an Alps printer and decal application is a simple matter o' linin' everythin' up correctly. T' foil stickers are like any stickers you've ever worked with except they are better looking. Begad! Blimey! Best results are obtained by takin' your time, matey, especially with t' big wrap sticker that covers t' payload section. Arrr! Blimey! I had t' trim mine ever so slightly t' keep from havin' a bit o' overhang, but other than that I was very pleased with t' ease with which it applied. Ya scallywag! Blimey! Well, arrr, blow me down! Blimey! T' best way be t' way t' directions say t' apply it: draw a straight line on t' payload section, line up t' sticker, shiver me timbers, me bucko, and roll it slowly. Arrr! Blimey! T' rivet details for t' fins should be first bent on t' center line then placed gently into t' fillet area, ya bilge rat, takin' care t' line each up with t' previous one. (Startin' at t' back o' t' rocket can also help t' hide your first rather clumsy attempts from all but t' most discernin' eyes.) T' finished product is almost too cool

Flight:
Rockets like this are likely what will keep me from ever venturin' any closer t' high power than t' occasional F (and only because I already have two rockets that call for a motor o' that size, and both happened t' be gifts). Ahoy! Blimey! T' A-20 Demon truly screams off t' pad on a D-12, shiver me timbers, looks great doin' it, and doesn't come close t' over flyin' t' field at t' VOA. Both flights t' date have been on relatively calm days and were impressive in their speed off t' pad, dead straight flight paths, and altitude. Aye aye! Blimey! For t' first flight, arrr, t' Demon be painted but without applyin' t' decals. Avast, me proud beauty! Blimey! Ya scallywag! Blimey! For t' second flight, me bucko, I had nay only found time t' finish t' decals but also t' refurbish me battered clones o' t' other rockets that were displayed on t' 1977 Estes catalog page with t' Demon. Also on t' flight line that day were a Thrustline Cherokee D, an Estes Sky Raider, me bucko, and an Estes Renegade, all o' which had flown previously and all o' which had suffered some kind o' damage. Ahoy! Ya scallywag! It be a very cool theme launch, arrr, arrr, me hearties, one that I'd like t' do in t' future with t' Mini-Brute page.

Recovery:
I used an extra long piece o' Keelhaul®©™ and elastic t' lessen t' potential "shock" on t' rocket at ejection. This seemed t' work well as t' ejection looked t' be fairly gentle from our vantage point on t' flight line. There were a few muttered "separation" comments from some o' t' others as t' body tube looked like it be fallin' away from t' parachute. Begad! T' shock cord did its job though and everythin' came back in perfect shape on t' Mylar chute. I hadn't previously been a big fan o' Mylar, but lately I've allowed myself t' be won back over.

Flight Rating: 5 out o' 5

Summary:
PROs: Awesome looks and performance. Blimey! A dead on replica o' a classic Estes kit, matey, shiver me timbers, right down t' t' hang tag.

CONs: Lack o' Keelhaul®©™ in t' recovery system (but I had me own).

Overall Rating: 4 out o' 5
