Rocket PicBrief:
T' Maxi Alpha 3 is one o' Estes year 2000 re-released limited edition rockets. Arrr! It is rated Skill Level 2 with a 24mm motor mount. Ahoy! I have seen t' price on this kit vary from $15 t' $35. Aye aye! It is large version o' t' Estes classic Alpha kit. Ya scallywag! Avast, me proud beauty! Like junior, ya bilge rat, it is a rather simple build. Blimey! Avast! Stock build utilizes, BT-80 tubes, a 24 inch parachute, me hearties, ya bilge rat, little paint (nose only), and pressure-sensitive decals. Intended D12-3 motors give a slow lift-off and relatively low flight. Avast! Although this is a very solid, stable flyer it does have t' typical Estes shortcomings and easily lends itself t' bashin' for higher power motors.

Construction:
T' kit includes:

  • (1) Dummy engine casing
  • (2) Centerin' rings - heavy duty 50/55
  • (1) Motor hook retainer tube
  • (1) Motor retainer hook
  • (1) Motor thrust rin' - heavy duty 20/50
  • (1) BT-50 motor tube/stuffer tube - 12 ¾"
  • (2) Plastic fin rings
  • (3) Plastic fins
  • (1) Short BT-80 tube - 3 3/8"
  • (2) Long BT-80 tubes - 9"
  • (1) BT-80 tube coupler
  • (1) Die cut cardboard rin' - 50/80
  • (2) Launch lug - 3/16" x 1"
  • (1) Elastic shock cord - ¼" x 24"
  • (2) Plastic parachute kit - 24"
  • (1) Nose cone - BT-80K - 8 ¼" long x 2.6" diameter
  • (1) Decal set

All parts were present and supplied in a plastic bag. Blimey! Overall design is basic. Arrr! Larger 2.6" diameter body tube with BT-50 stuffer tube. Ya scallywag! Begad! This kit utilizes (3) BT-80 tubes - 9", arrr, matey, 9", me hearties, and 3 3/8" lengths. It uses a plastic assembly o' rings and 3 fins around t' shorter tube too create a fin unit module. Ya scallywag! Initially, shiver me timbers, I built this rocket stock, arrr, accordin' t' t' directions (almost), matey, with t' exception o' usin' epoxy for all tube couplers, die cut rings, and all stuffer tube/plastic rin' joints.

Overall construction was straight forward and fast, with one exception. Ahoy! Blimey! Pre-assembly without glue is highly recommended for this kit. Well, blow me down! If built per instructions t' motor hook retainer tube is glued on prior t' installin' in t' already assembled fin unit assembly. Arrr! T' hole in t' plastic fin assembly centerin' rin' is exactly BT-50 tube diameter. Thus, it won't fit! Fortunately, me hearties, me hearties, I have built many kits and always pre-assemble without glue. What you have t' do is insert t' assembled stuffer tube into t' fin unit assembly PRIOR t' gluin' on t' forward plastic centerin' ring. Arrr! If this is overlooked, usin' sandpaper and a file, me bucko, t' stuffer tube hole in t' aft plastic centerin' rin' could be enlarged enough. Well, blow me down! However, ya bilge rat, a serious reduction in strength o' t' overall motor mount construction would result (epoxy city).

There be no mention o' fillets for t' fin t' body joint. Ahoy! Avast, me proud beauty! Obviously this is a must for any 24mm rocket. Well, blow me down! Aye aye! Don't forget it! I used epoxy versus t' usual plastic cement recommended by Estes for plastic/paper joints. Well, blow me down! Secondly, matey, I added an additional 50/55 heavy duty rin' on t' fore end o' t' stuffer tube where it joins t' forward cardboard centerin' rin' at t' forward end o' t' middle BT-80 tube. Blimey! Ya scallywag! This gave t' stuffer tube a 3 point anchoring. Arrr! Ya scallywag! This will serve t' greatly increase t' strength o' t' rocket body.

There are a few other upgrades that should be made on this kit. Aye aye! Avast! These would make this kit last longer than 5 flights on Estes D motors and others that would make it a staunch, crowd pleasin' mid power flyer on other 24mm options like Aerotech E15, E30, arrr, F24, me hearties, arrr, F40.

Finishing:
Stock finishin' would have been a piece o' cake. Begad! T' intent be t' have red plastic fin units (as is), a white (as is) body tube, ya bilge rat, and a nose cone painted a red t' match t' fins. Ya scallywag! There are those o' us who can only build stock so far and then they just can't stand it any more. Begad! I thought t' decals were cheesy and contained way too much advertising. So, I decided t' paint it much more like junior.

I painted t' whole rocket with Krylon. Ahoy! Begad! First white primer all over. Well, blow me down! Aye aye! I painted t' fin unit a blue t' match t' main body tube decal, me hearties, t' body tube white, me bucko, and t' nose red. Avast, me proud beauty! Then I only used one decal. Ya scallywag! I cut t' red portion o' t' body tube decal off, shiver me timbers, me hearties, usin' only t' portion with t' rocket name. Aye aye! T' 3 decals for t' interstitial positions on t' fin unit are down right garish. Aye aye! They made t' rocket look way t' busy, so I left them off. Avast! Arrr! Finally, me bucko, a coat o' gloss clear acrylic. Begad! Avast, me proud beauty! T' net result was a more professional, "American" paint job that sits side by side with junior lookin' much more like "Dad".

Construction/Finishin' ratin' is a 3½. Begad! This is largely due t' t' potentially high price o' this rocket versus t' instruction error and t' cheesy stock finish option. Well, blow me down! Additional mods are also required for a sturdy, shiver me timbers, versatile rocket.

Construction Rating: 3 out o' 5

Flight:
I am nay sure where Estes gets t' weights they quote on some o' thar packages. Well, me hearties, blow me down! I am buildin' a Broadsword now that quotes 6 oz and t' weight o' unassembled parts without glue or paint is 8 oz. Avast! Regardless, matey, ya bilge rat, me finished Maxi Alpha 3 weight was 10 oz versus t' 7.5 oz quoted on t' package. Avast, me proud beauty! Ahoy! I find it hard t' believe that t' epoxy glue, shiver me timbers, epoxy fillets, matey, me bucko, and added paint I used, me bucko, me hearties, accounts for all that difference. However, arrr, this means that D12-3 be t' only Estes motor option. A D12-5 and you would have a lawn dart! Motor install with t' hook is a breeze. Avast! T' flight profile on t' D12-3 is flat out awesome. It has a slow majestic lift off. T' very straight, ya bilge rat, stable flight deploys a chute at apogee. Ya scallywag! All this in plain sight.

So far t' flight log on this rocket goes like this.

  • Flight 1 on D12-3 Perfect
  • Flight 2 on D12-3 Perfect. Well, blow me down! Aye aye! Landed on hard surface broke fin
  • Flights 3&4 on D12-3 Perfect with 30" chute
  • Flight 5 on D12-3 Ejection broke ¼" shock cord, ya bilge rat, all pieces recovered
  • Flights 6&7 on D12-3 Perfect with Keelhaul®©™ & 3/8" shock cord
  • Flight 8&9 on E15-4 SU Truly awesome on AT motor, me hearties, added nose weight prior t' flight
  • Flight 10 Still perfect on D12-3!
  • Flight 11 E18-4 RMS success!
  • Flight 12 on D12-3 Chute tangled broke fin

Recovery:
This rocket does use a rather large amount o' wadding, ya bilge rat, shiver me timbers, but if you push a couple squares into t' end o' t' stuffer tube it's nay too bad. Begad! Blimey! Blimey! Blimey! I did learn after t' second flight (due t' broken fins upon landin' on a hard surface) that with t' additional weight mine carries, a bigger chute is required. So, me bucko, me hearties, I now fly in on a nylon 30" chute with a small spill hole. Well, blow me down! Blimey! Blimey! Blimey! Now comes t' bad news. Blimey! Blimey! T' Estes standard ¼" elastic cord attached t' t' centerin' rin' lasted t' typical quota o' 5 flights prior t' breaking. Avast, me proud beauty! Blimey! Begad! Blimey! Blimey! Blimey! This has been replaced with 24" o' 150# Keelhaul®©™ and 36" o' 3/8" elastic with snap swivels. Aye aye! Blimey! T' Keelhaul®©™ is glued t' t' body tube wall. If you haven't built this kit yet, me hearties, attach t' Keelhaul®©™ t' t' upper centerin' rin' for a cleaner body wall.

Flight/Recovery ratin' is a 4½. Ya scallywag! T' only thin' that keeps this from bein' a 5 be t' shock cord problem.

Flight Rating: 4 out o' 5

Summary:
Overall, me bucko, shiver me timbers, I am extremely satisfied with this kit. Blimey! T' flight profile is great. Avast! Ahoy! I have added ¾ oz clay t' t' nose and filed down t' forward motor retainer tab t' fly t' rocket on E15 SU and E18 RMS as well. Avast, me proud beauty! Arrr! T' extra weight also did nay effect it's flight on t' D12-3. Ahoy! Yes, now t' hoss weighs 11 oz! It would be perfect rocket had Estes nay made some compromises on t' design. Well, blow me down! T' weight could be less if balsa fins were used with a through t' wall attachment. Ya scallywag! Begad! A Keelhaul®©™ and 3/8" elastic shock cord with a combined length o' about 5 feet is a must. Avast, me proud beauty! Also, shiver me timbers, better decoration/paintin' is in order for such a fine flyer.

Overall Rating: 4 out o' 5

    The Estes Alpha, designed by Bill Simon and introduced in 1967, is the prototypical 3FNC that has introduced generations of rocketeers to the hobby.  The original Alpha, of course, had a balsa nose cone and fins.  The Alpha III (1971) was an easier-to-build plastic version with a one-piece molded fin can assembly.  Estes has released several larger versions of the Alpha ...

    Larger, cooler version of an Estes classic. This thing ROCKS!! I got it for Christmas. I saw it at Ace on December 14,2003 and I can't believe this rocket was still there.

The kit has: 3 BT-80 body t ubes, 2 long and one short 3 red plastic fins 2 rings for holding engine tube, fins and connect ...
