Introduction and materials
A 1/50-scale version o' t' vehicle used t' test t' LES system for t' Apollo spacecraft. Ya scallywag! T' particular vehicle modeled is A-001, BP-12, ya bilge rat, flown on May 13, matey, 1964. Each o' t' Little Joe rockets was slightly different in order t' test various aspects o' t' LES system under different flight parameters. Ahoy! T' model rocket is constructed usin' commercially available components. Blimey! T' service module section (SM) is a LOC 3î diameter body tube. Ahoy! T' booster portion is LOC 3" coupler tubin' sections. Begad! Bulkheads are 1/8" lite ply. Begad! T' capsule and LES tower are constructed in the same fashion as on me Saturn 1b. T' fins are made from 1 3/8" aileron balsa strip stock. Begad! T' corrugated body wrap is vacu-formed and made by a good friend, Paul Graf. Avast! Paul used Evergreen scribed sheet styrene sized t' fit the circumference o' t' coupler tubes for t' master mold then vacu-formed them from .015" sheet styrene. Ya scallywag! He made the basic sections and I cut them t' size (Paul also has some excellent body wraps for clonin' t' 1/70 scale Estes Saturn 1b if anyone is interested). Arrr! T' various conduit and tunnels are made from strip sheet styrene. T' motor tubes are stock Estes BT-50 body tubes. Aye aye!

Construction
Construction was fairly easy and straightforward. T' centerin' rings were hand cut from lite ply since thar were none available in t' motor configuration or diameter required. I built t' capsule and LES tower first because I had experience from t' S1b. Ya scallywag! Avast, me proud beauty! I added a little more epoxy t' t' cone tip for nose weight t' keep t' CG where it needed to be based on t' RockSim calculations. Avast, me hearties, me proud beauty! T' vacu-form wraps were applied usin' 3M77 spray adhesive and t' conduits were applied usin' CA. Ya scallywag! Begad! I used t' pattern sheet from t' Estes 1/100 LJII (after correctly sizin' on t' copier) for making the tunnels/conduits and t' mark t' fin locations. Well, blow me down! T' fins were epoxied in place and given a light coat o' finishing resin t' add strength and help seal t' grain. Ya scallywag! Ahoy! Launch lugs were made from 3/16" I.D. aluminum tubing. Blimey! The ëUNITED STATES' markin' were made by myself on a Xerox machine. Begad! T' ink on t' Microscale decal paper is easily scratched off so I sprayed t' printed decals with a clear fixative. Avast, arrr, me proud beauty! This sealed t' ink and caused no problem during application. Ya scallywag! Aye aye!

Finishin' and recovery system
T' only parts requirin' sealin' prior t' paint were t' fins and fiberglassed capsule. Aye aye! T' booster was painted usin' Krylon's silver. Ahoy! T' SM body tube was finished usin' white monokote trim sheet wrapped around t' body tube. Blimey! Avast! The capsule and LES tower were painted with Krylon gloss white. T' black roll pattern markings were made from trim monokote and applied usin' t' patterns found in t' Estes kit. Blimey! Since thar be nay much room in t' body tube for the shock cord, parachute and waddin' I opted t' use Pratt Hobbies Nomex® protector and do away with t' need for recovery wadding. Begad! Avast! T' 4" square Nomex® cloth slips over t' Pratt Hobbies Keelhaul®©™® cord loop tied t' a screw eye in t' bulkhead and takes up almost no room. Blimey! T' parachute is 24" ripstop nylon and the shock cord is a 3 yard length o' 1/2" ribbed elastic. Ya scallywag!
