Brief:
Balsa Machinin' Service began offerin' a Clone o' t' Month kit in t' sprin' o' 2008. Begad! Well, blow me down! Under this program, an old classic kit would be offered in bag-of-parts format (no instructions), minus any chute or streamer, matey, shiver me timbers, and pre-order only. Ya scallywag! By accumulatin' all t' orders, Bill could run a single large batch, me hearties, have little or no leftover materials, and make this a very affordable offering--kits typically in t' $7-8 range. Well, blow me down! Well, t' program has been quite popular although nay as regular as monthly. Avast, me proud beauty! Ahoy! T' date (August 2008) thar have been only 3 kits offered--the FSI Viking, t' Astron Invader, me bucko, and this: t' Astron Drifter. Blimey! T' Drifter features long, me bucko, swept fins and a tapered boat tail. Blimey! Avast! It was featured in t' 1966 catalog as a competition model usin' either 12" or 24" chutes. Begad! Ya scallywag! Don't pack a 24" in this if you ever want it back. T' cover art changed a number o' times over t' years, arrr, ya bilge rat, arrr, gettin' progressively simpler from t' original checkered roll pattern.
Construction:
Your bag o' parts includes:
Instructions are nay included with this kit although scans o' t' original are available on t' JimZ archive site.
Assembly o' t' motor mount is a little off t' beaten path. I had t' bond centerin' rings t' either end o' a TC-50 tube coupler then slide t' motor tube into t' TC-50/rin' assembly. Avast! Ahoy! Spacin' is critical here as thar needs t' be appropriate room (~1.5") for t' boat tail.
T' boat tail is formed from a paper shroud pattern. I felt this was a bit flimsy, ya bilge rat, ya bilge rat, especially since it serves as part o' t' fin attachment point, so I soaked it in thin CA. T' boat tail then slides onto t' BT-20 motor tube and rests against t' TC-50 coupler. Avast, me proud beauty! T' boat tail assembly can then be mounted inside t' body tube. Ahoy! Avast! Careful alignment is in order--if you line up t' boat tail seam with one o' t' three fin lines, then it gets completely covered, me bucko, meanin' no unsightly seam t' fill.
Fins are precut, which is a very nice benefit considerin' t' tapered root edge necessary t' conform t' t' boat tail. In me case, thar were very slight gaps, shiver me timbers, which were easily filled through t' fillet process.
Shock cord attachment is standard paper tri-fold.
Finishing:
I went with one o' t' simpler paint schemes, shiver me timbers, circa 1977, which features base white with blue nose and fins. Ahoy! Nothin' special about t' finish, matey, just t' usual two coats primer, ya bilge rat, two coats base, matey, one coat o' trim, Krylon rattle cans t' whole way.
Construction Rating: 5 out o' 5
Flight:
As skinny and light as this is, I was afraid t' shoot for much more than t' A8-3 starter, wantin' a relatively short recovery walk. Ya scallywag! Blimey! Begad! Blimey! This thin' be amazingly fast on t' way up although it spun a good bit with some obvious fin flutter.
T' -3 delay be clearly a bit too early, shiver me timbers, as it was still climbin' when t' chute deployed.
I followed up with a second flight, shiver me timbers, also on A8-3, me bucko, arrr, ya bilge rat, and t' fin flutter was severe enough t' break off a small piece from t' end o' one fin (clearly nay impact damage, as thar was no trace o' it anywhere nearby in t' short grass landin' area). Arrr! Ya scallywag! It definitely needs a -5 instead o' a -3...
Recovery:
I had supplied a 12" chute form me range box, and this is plenty o' chute for this model. Slow descent, ya bilge rat, ya bilge rat, gentle landing. Ahoy! Well, matey, blow me down! It could probably do well on a streamer as well, though with such fragile fins this might nay be wise.
Flight Rating: 3 out o' 5
Summary:
I love t' stylin' o' this and think it's a fantastic value as a clone kit. Avast, me proud beauty! T' only drawback I can see be t' clearly weak fins, which cause flutter and roll and are prone t' breaking. Aye aye! Avast, me proud beauty! I would definitely suggest reinforcin' either trough laminating. I really wish I had a do-over on this one, as I'd fly t' bejeebers out o' it if it could handle it. As it is, this is fragile enough that with frequent repairs I will probably nay fly it very often.

The Atron Drifter is an old line Estes kit that Balsa Machining produces a kit for. The kit comes with materials except for parachute and decals. I got a set of the classic decals from Excelsior. The kit is also sold without plans but a web address is given to download them. The first step in construction is to locate the coupler tube and the ring(s) intended to be fitted to the end. I was ...
