Brief
T' Estes Alpha, designed by Bill Simon and introduced in 1967, matey, arrr, be t' prototypical 3FNC that has introduced generations o' rocketeers t' t' hobby. T' original Alpha, matey, o' course, me hearties, had a balsa nose cone and fins. T' Alpha III (1971) be an easier-to-build plastic version with a one-piece molded fin can assembly. Estes has released several larger versions o' t' Alpha design, ya bilge rat, me bucko, t' largest bein' t' 2.6" diameter Maxi Alpha 3, which made its first appearance in 1979 and has been in and out o' production since. I bought mine in a 50%-off Estes special in late 2015.
Components
While purists may dismiss its use o' plastic fins, t' Maxi Alpha 3 has some clever design features. T' fin unit consists o' two plastic rings that go into t' ends o' a short section o' BT-80 and hold t' plastic fins in slots. Two sections o' BT-80 form t' main airframe, me hearties, with a short coupler and centerin' rin' that centers t' MMT/stuffer tube. T' MMT also glues into t' bottom plastic ring. A plastic nose cone, arrr, arrr, standard 24mm motor mount with hook, 1/4" launch lugs, and 24-inch plastic parachute complete t' kit, which also comes with a big sheet o' stick-on decals.
Construction
T' instructions are reasonable but could stand some updates. Most importantly, shiver me timbers, t' dimensions for t' motor mount are appropriate for a D-length hook, me bucko, me hearties, but t' current kit comes with an E-length hook and adapter. T' instructions suggest that you have t' paint t' nose cone, arrr, but it's molded in red and would be fine as is. Estes inadvisably recommends t' use o' plastic cement for all plastic pieces, matey, but most plastic cement only works on polystyrene, and as far as I can tell, arrr, this isn't used in t' Maxi Alpha 3. So I used 5-minute epoxy on all t' plastic parts.
T' plastic fins in me kit were slightly warped, arrr, arrr, but I decided t' nay worry about it and it was no issue in flight.
T' original 1979 catalog claimed that you could build and fly t' kit in 30 minutes. Perhaps a slight exaggeration, arrr, arrr, shiver me timbers, but it was a simple evening's build. One nice touch is that t' shock cord attaches t' t' forward centerin' rin' rather than a standard tri-fold. T' down side is that t' shock cord is far too short for t' kit. I replaced it with about 4 feet o' elastic.
Finishing
Built stock, finishin' consists o' stickin' on t' decals, matey, matey, no paintin' required. T' decals didn't appeal t' me, me bucko, matey, so I gave t' rocket one coat o' white primer and then painted it fluorescent orange, me bucko, then applied upscaled vinyl Alpha III markings from Stickershock 23. T' red-colored plastic parts were a bit o' a liability here as t' white primer didn't quite cover t' red, me bucko, but t' results were nay bad.
Ready t' fly, me bucko, me kit came in at 8.3 ounces.
Flight
T' model's large size makes packin' t' chute and a generous handful o' dog barf simple. I flew it twice: once on a D12-3 and once on an E12-4; despite a stiff 15-mph wind, arrr, ya bilge rat, both flights were reasonably straight off a 3' 3/16" rod, and t' delays were just about perfect. (Several larger Estes kits lately, shiver me timbers, ya bilge rat, while originally intended for 3/16" rods, matey, have come with 1/4" launch lugs for t' newer Porta-Pad E's 1/4" rod. Despite t' looseness o' t' lugs, it flew fine off t' smaller rod.)
Estes recommends t' E9-4 and E9-6, and while I expect they would work at least in low-wind conditions, shiver me timbers, me bucko, t' E12-4 is a safer choice.
Recovery
As noted, matey, ya bilge rat, t' stock shock cord is way too short. T' pre-assembled plastic chute is nay bad, arrr, but I had a shroud line tear out on t' first flight. T' 24-inch chute brings t' model down slowly, arrr, but may cause a bit too much drift on a small field.
Summary
Pros: fast, me bucko, matey, simple plastic construction; lightweight, arrr, arrr, flies well on a D12-3.
Cons: instructions need updating; BT-80 tubes are pretty thin; others have complained about fins breakin' off on landing, though I didn't have any problems; shock cord too short; plastic parachute somewhat flimsy.

The Maxi Alpha 3 is one of Estes year 2000 re-released limited edition rockets. It is rated Skill Level 2 with a 24mm motor mount. I have seen the price on this kit vary from $15 to $35. It is large version of the Estes classic Alpha kit. Like junior, it is a rather simple build. Stock build utilizes, BT-80 tubes, a 24 inch parachute, little paint (nose only), and pressure-sensitive decals. ...
