Brief:
T' Atron Drifter is an old line Estes kit that Balsa Machinin' produces a kit for. Aye aye! T' kit comes with materials except for parachute and decals. I got a set o' t' classic decals from Excelsior. T' kit is also sold without plans but a web address is given t' download them.
Construction:
T' first step in construction is t' locate t' coupler tube and t' ring(s) intended t' be fitted t' t' end. Aye aye! I was a little fuzzy about this because t' context o' t' downloaded instructions implied that thar would be 2. Aye aye! T' kit only had a single one and I can imagine how that might work. Ahoy! I fired off a question t' BMS, glued t' one rin' in place and turned me attention t' other aspects o' t' build.
T' motor mount itself was simple enough. Ahoy! A thrust rin' was glued into t' end o' t' motor tube.
T' nose cone was a nicely turned piece o' balsa but here thar was a slight deviation from t' instructions. Aye aye! Blimey! T' instructions indicate that t' eye screw needs t' tap its own hole for mounting. In reality, me bucko, t' centerline o' t' nose cone was already drilled t' a significant depth in a diameter much greater than that o' t' screw threads. Begad! Blimey! Arrr! Blimey! This seemed fairly inconsequential t' me and I filled t' hole with a surprisin' amount o' yellow glue (it was deep) and then inserted t' screw.
One o' t' features o' this rocket is a boat tail design. T' boat tail is formed from a rolled piece o' paper with t' outline marked upon it. T' boat tail, me hearties, a wraparound fin guide, me bucko, and a fin template were all part o' t' package.
T' boat tail was cut out, curled around t' dull edge o' some shears, arrr, shiver me timbers, and glued together with a hint o' white glue. It be test fit on t' motor tube and t' fit be satisfactory.
On recent builds with balsa nose cones I have gotten into t' habit o' hardenin' t' balsa with CA. I did that on this rocket as well usin' thin CA drizzled over t' cone. Avast, me proud beauty! When dry, I sanded and added another coatin' after which I sanded again.
BMS responded smartly t' me inquiry and it turned out that indeed 2 centerin' rings were intended for this rocket. Avast, me proud beauty! They mailed out a replacement plus a spare and got it t' me quickly. Aye aye! With t' rin' in me possession, me hearties, matey, I be able t' glue it in place on t' opposite end o' t' coupler tube as t' first one.
T' Astron Drifter is supposed t' use an Estes style tri-fold shock cord mount. Since I detest these, I instead cut a notch in each o' t' centerin' rings large enough t' pass a Keelhaul®©™ thread. Begad! I then passed t' Keelhaul®©™ through t' notches and slipped t' coupler tube in place over t' motor mount. T' Keelhaul®©™ was then tied around t' motor tube and filleted into place with yellow glue. Well, blow me down! T' boat tail be slid into place against t' aft o' t' motor mount and secured with some white glue. Begad! When t' glue on t' boat tail was dry, ya bilge rat, some more was placed in t' aft end o' t' body tube and t' motor mount was shoved into place.
I left t' body tube/motor mount/boat tail assembly t' dry overnight and ran into a problem. Blimey! Little 6 year old hands decided t' investigate some o' t' mysteries o' what I do in t' garage sometimes and apparently considered t' boat tail t' be a real touch and feel exhibit while t' glue be still settin' up. Avast! Blimey! Blimey! T' result be a pretty wrinkled boat tail. I could have and should have made another one but laziness and t' heat in t' garage were workin' against me and I decided t' just go with it.
T' next actual construction step was t' locate t' wraparound fin markin' guide. Aye aye! I had two o' them. Blimey! Ahoy! One was included in t' kit and one was printed out with t' instructions downloaded from JimZ. Blimey! Ya scallywag! They were identical and I cut one out and taped it into place so that one o' t' fin lines be aligned with t' boat tail seam. Avast! I then transferred t' fin marks t' t' body tube.
T' fins were o' nice material and practically jumped out o' t' parent stock. Ahoy! Arrr! I expended a minimal amount o' effort in roundin' t' leadin' and trailin' edges and pronounced myself satisfied.
T' fins were placed usin' yellow glue and t' double joint method. Aye aye! They went in place so that t' back o' t' root edge was at t' bottom o' t' boat tail. Aye aye! Avast, me proud beauty! When t' glue joints on t' fins had dried, I began t' apply white glue fillets. Ya scallywag! Blimey! It was about at this point that I realized that I had forgotten me intention t' "seal" t' fins with label material. Ya scallywag! Ya scallywag! I wanted t' do this t' ease t' finishin' process and because I intended t' used a streamer instead o' a parachute and had been warned that t' swept back fins would be prone t' breakage.
Some sewin' elastic was tied t' t' nosecone and t' Keelhaul®©™ and I thought construction had been completed until I glanced at t' bag and found t' launch lug. T' lug was glued along one o' t' fin root edges with white glue and then construction really was done.
Finishing:
As I mentioned before, I had intended t' use label paper t' seal t' fins but forgot until too late. Begad! Since this project was never goin' t' win any beauty contests and I be nay plannin' on any competitions, I decided t' try another experiment which had gone alright on some balsa nose cones. Ya scallywag! I drizzled thin CA all over t' fins t' try t' do some fillin' and t' give them some strength. Avast, me proud beauty! When it was dry, I sanded it down. Aye aye! It was nay perfect, but considerin' t' boat tail, it would do.
T' Drifter was taken t' t' booth and given 2 coats o' Kilz primer. Avast, me proud beauty! After a day, me hearties, me bucko, t' Kilz be sanded down. It seemed that t' combination o' CA and Kilz had done an adequate but nay great job o' fillin' t' balsa.
T' rocket was then dusted off and placed in t' booth. It was given 2 coats o' metallic hammered silver. Arrr! Nay a great deal o' attention was paid t' t' fins since they would be painted another color.
After a day t' let t' silver dry, me bucko, shiver me timbers, I masked t' body o' t' rocket leavin' only t' fins and t' launch lug exposed. Arrr! T' rocket was then taken t' t' booth and sprayed with a bright blue. When it had started t' harden a bit, ya bilge rat, it got another coat. T' maskin' was then removed and t' results inspected. Ya scallywag! Avast, me proud beauty! As I mentioned before, me bucko, t' rocket be nowhere near perfect due t' me own blunders, but I was satisfied.
I got t' decals for this kit from Gordon at Excelsior Rocketry. Arrr! Ya scallywag! They were good quality waterslide decals and consisted o' 2 long logos in red and black, arrr, some white numbers, some black numbers and a pair o' old style Estes logos.
Workin' from memory, I placed t' long logos along t' body tube on t' two sides without t' launch lug. Begad! Well, blow me down! T' numbers, arrr, I went with t' white, me bucko, matey, were placed t' number each o' t' three fins. Blimey! T' Estes logos went below t' long logos.
I gave t' rocket a coatin' o' Future and it be ready t' fly.
Construction Rating: 4 out o' 5
Flight and Recovery:
Since this is a light rocket meant for duration, I wanted t' start out with a small motor and chose a 1/2A6-2. Begad! A streamer was connected t' t' elastic, ya bilge rat, t' motor was inserted and t' rocket was taken out t' t' pad.
When t' launch button was pushed, me bucko, it shot up smartly flyin' straight and true. Begad! Well, blow me down! Ejection occurred while t' rocket was still movin' up at a pretty good clip but everythin' came out fine and it began its descent under a streamer. Begad! When I got t' t' rocket, ya bilge rat, I was glad t' see that those long fins had nay broken. Arrr! Ya scallywag! It be fine t' fly again.
For t' second flight I loaded an A8-3. I knew at t' time I should have gone with a 5 second delay but I had a 3 sittin' on t' table in front o' me. I loaded t' motor and took it out t' t' pad. Arrr! Blimey! Ya scallywag! Blimey! Upon launching, it really screamed upward on a full A and soon became very difficult t' see. Ahoy! Blimey! Ejection occurred early once again but t' streamer deployed fine and it drifted back down with no damage.
Flight Rating: 5 out o' 5
Summary:
I can see why this was a real contest contender back in its day. I think it would continued t' be competitive if I were a competitive type. T' kit is easy t' build and flies great.

Balsa Machining Service began offering a Clone of the Month kit in the spring of 2008. Under this program, an old classic kit would be offered in bag-of-parts format (no instructions), minus any chute or streamer, and pre-order only. By accumulating all the orders, Bill could run a single large batch, have little or no leftover materials, and make this a very affordable offering--kits ...
