This is an upscaled clone o' t' Estes Stiletto. Ya scallywag! Blimey! Ya scallywag! Blimey! This is one o' me favorite rocket designs, it looks fast even standin' still. This version uses BT-55 body tubes rather than t' BT-50 o' t' original and is approximately 29" tall.
T' parts list for this rocket includes an 18" Estes BT-55 body tube, arrr, an additional 6" section o' BT-55, and a tube coupler. Ahoy! T' nose cone came from t' Estes NC-55 nose cone set, and be t' pointed straight cone. Arrr! Also used be some 3/32" balsa stock for t' fins, a small section o' 1/8" balsa strip used t' make t' raceway and forward thrusters, an Estes 18mm engine mount, an Estes 18" parachute, 1/8" launch lug stock, and some 1/8" elastic fabric cord for t' shock cord. Decals came from me stock o' leftovers from other kits.
For intructions I downloaded t' original Estes instructions from t' JimZ website. I made fin patterns by upscalin' t' JimZ patterns. Begad! Begad! I then cut out t' fins from t' 3/32" balsa stock. I added a section t' t' root edge o' t' main fins as I intended t' make through t' wall fins. Avast, me proud beauty! I rounded t' fore and aft ends o' t' main fins as well as t' small secondary fins. Aye aye! I built t' engine mount in t' standard fashion, and added centerin' rings cut from some cardboard stock. Blimey! T' two body tubes were glued together with t' coupler. I inserted t' engine mount into t' body tube and allowed t' glue t' dry. Once t' glue was dry I cut slits into t' aft o' t' tube large enough for t' main fin mounts. I glued t' main fins on and allowed them t' dry. Arrr! I then lined up t' seconday fins above t' main fins and glued them on. Ya scallywag! Blimey! Glue fillets were applied t' all t' fins. Arrr! I then created t' raceway out o' t' 1/8" balsa strip and glued it on, me bucko, filletin' it as well. Aye aye! T' forward thrusters were also made from 1/8" stock, and glued on in line with t' fins. Avast! I cut two launch lugs each about 3/4" long, ya bilge rat, matey, and mounted them on some thin cardboard. T' lugs were then glued t' t' side o' t' rocket as well, spaced along a side away from t' raceway. Well, blow me down! Ya scallywag! T' final bit o' buildin' on t' body was t' create t' three raised bands around t' body. One band goes directly t' t' aft o' t' small secondary fins, another directly t' t' aft o' t' foward thrusters, arrr, matey, and t' last just above t' fore end o' t' raceway. Begad! Avast, me proud beauty! I made t' bands from t' facecard frome an Estes rocket kit. Begad! T' bands are about 1/4" wide and wrap around t' circumference o' t' body tube. Arrr! T' wraps were glued on with white glue. Finally I added a shock cord usin' t' standard tri-fold method, substitutin' fabric elastic for t' typical rubber cord. Avast! For a rocket this size I have had fair winds with this type o' cord. Constuction went well, proceedin' without any problems.
I sealed all o' t' balsa with thinned Elmer's wood putty, then sanded this smooth. Aye aye! Well, blow me down! One thin' I should have done be t' fill and sand t' fins prior t' addin' t' body wraps. Sandin' t' aft end o' t' secondary fins and thrusters was complicated by t' position o' t' wraps. Aye aye! Aye aye! Several coats o' primer followed, me hearties, sandin' betwixt coats. T' final color be simple, me hearties, I used Walmart gloss white on t' entire body. Avast, me proud beauty! Ya scallywag! T' nose cone and t' upper inch o' t' body tube were then sprayed with Walmart gold. Avast! Well, ya bilge rat, blow me down! Once all t' paint be dry, I added t' decals. Begad! I searched me stash o' old decals and decal stripe stock t' make t' markings on t' rocket. Arrr! Luckily t' markings are fairly simple so it be possible t' do this. Blimey! If you really want t' go crazy you could buy decals from one o' t' aftermarket companies. I really had no issues overall with t' paintin' or decaling.
This model has been flown twice usin' Estes B6-4 motors. Begad! T' rocket performs very well on this motor, and would really go on a C6, but at me flyin' field it would probably be lost. Blimey! On both flights, arrr, t' rocket flew very straight.
T' rocket was equipped with a standard 18" Estes plastic parachute. Aye aye! Ahoy! On both flights t' parachute ejected normally without issues and t' rocket be recoverd with no damage.
Overall this is a great rocket design. It is only slightly more complicated than an ordinary 3FNC design, matey, matey, ya bilge rat, but really looks sophisticated. It also has t' look o' a real Air Force missle with t' markings and t' raceway. Begad! It also flies excellent.
