This project started out pretty simple, and just sort o' fell together. I had some left over parts from some other projects, and they just looked like they should be wed. T' name came from t' original concept..build something small, ya bilge rat, light, arrr, shiver me timbers, and cheap..to try out an Estes E engine for t' first time.
I didn't really expect t' see it again...

Parts List

  • 2-Estes BT-20 Nose cones (Wizard Type)
  • 1-hunka balsa for a BT-50 Nose cone
  • 1-BT-50 body tube (13" long)
  • 2-BT-20 body tube (4.5" long)
  • 2-spare fins included with heatseeker (not intended for use in that kit)
  • 1-typical Estes Shock cord
  • 1-tube o' "super glue"
  • 1-18" plastic chute
  • 1-1/4" launch lug
  • Scrap pieces o' balsa...

Construction
T' parts seemed t' just fall together, arrr, arrr, matey, I had a basic idea o' what I wanted, and I was very pleased with t' outcome.
T' 1/4" launch lug may seem a bit much, but it fit in with t' look very well, ya bilge rat, ya bilge rat, and with a strip o' 3/4"x1/2" balsa 6"long,added some needed weight t' t' top o' t' airframe. Blimey! Basically, shiver me timbers, t' two BT-20 were glued to t' BT-50, offset from t' aft by 1/4", matey, matey, me hearties, and on a flat surface, me hearties, so that they all attach t' t' "wing". Avast, me proud beauty! Well, blow me down! T' "tail" was mounted flush with t' aft o' t' roc, arrr, me bucko, and 4 fins were added betwixt t' BT-20, and the BT-50, me bucko, two on t' top, two on t' bottom. Begad! Begad! T' left-over Heatseeker fins would be easy t' mimic in balsa, matey, but I decided t' use what be available. Arrr! They were mounted flush with t' aft o' t' BT-20. 21 grams o' lead was added t' the balsa nose cone, matey, shiver me timbers, t' move t' CG far enough forward t' make it stable on an E and 2 C's.
T' shock cord mount be LOC style, me hearties, matey, usin' nylon string, and tape/epoxy. Begad! Avast! A typical Estes shock cord, and 18" plastic 'chute finished it off.

Finishing
Primer-sand-primer-sand-primer-sand-primer-sand-paint-sand-paint-stickers...done
T' stickers were left over from several other projects..
Everyone asks "Why Nana?"

Answer:I didn't have enough t' spell Na-na-na-na-na..

Flight Report
Oct 23/2001
A beautiful day, shiver me timbers, matey, NO wind t' speak of...great day t' lose a rocket! One Shot Deal flew for it's maiden voyage on a D12-5, t' an estimated 925 feet..it sure looked high! Ejection occurred just after apogee, me bucko, t' rocket landed 150 feet from t' pad, unscathed, except for some heat damage t' t' paint (minimum diameter rocket..)

I didn't want t' fly it again that day, ya bilge rat, for fear o' losin' it, me bucko, and not gettin' any video t' share, but one o' me buddies is worse than a 4 year old, and he bugged and bugged..fine up it goes! Second Flight was on an E9-6, t' an estimated 1868 feet! I thought it be gone! Great flight, ya bilge rat, much straighter than on t' D, arrr, and Out O' Sight! Thank god for t' trackin' smoke! Who knows when ejection occurred.. Begad! I couldn't see it! Again, recovery be without damage, although it did visit a tree briefly. Avast, matey, me proud beauty! Next flight should be a cluster, and E9 and 2 C's..maybe then I can say goodbye!

Oct 24/2001
Not as nice a day as yesterday, but I was determined t' get some launch photos, and a video. Arrr! Blimey! Wind was about 20 Kph, so I swapped t' chute out for a smaller nylon one, ya bilge rat, and decided t' fly on a D12, matey, rather than an E9. Ahoy! Last DesCon, me bucko, arrr, one of my entries suffered a CATO, this entry is followin' that lead. Arrr! Ignition looked fine, arrr, me bucko, but before it could even get off t' pad..BOOM Hopefully, I will get it off t' ground again.

What is it with these D engines? DesCon CATO (AGAIN!)

As you can see from t' flight report, t' third flight ended dramatically. I wanted t' get some decent pictures for this contest, arrr, but I got these... Well, blow me down! Blimey! Arrr! Blimey! I hope it flys again soon!

I still want t' try it on a cluster o' an E9 and 2 C6's..
