Rocket PicBrief:
T' Maxi Alpha 3 is one o' Estes year 2000 re-released limited edition rockets. Avast, me proud beauty! Aye aye! It is rated Skill Level 2 with a 24mm motor mount. Avast! I have seen t' price on this kit vary from $15 t' $35. Begad! Begad! It is large version o' t' Estes classic Alpha kit. Aye aye! Well, arrr, blow me down! Like junior, ya bilge rat, it is a rather simple build. Well, blow me down! Stock build utilizes, BT-80 tubes, arrr, a 24 inch parachute, ya bilge rat, little paint (nose only), and pressure-sensitive decals. Intended D12-3 motors give a slow lift-off and relatively low flight. Although this is a very solid, me bucko, 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. Overall design is basic. Well, blow me down! Larger 2.6" diameter body tube with BT-50 stuffer tube. Avast! This kit utilizes (3) BT-80 tubes - 9", 9", me hearties, and 3 3/8" lengths. Arrr! It uses a plastic assembly o' rings and 3 fins around t' shorter tube too create a fin unit module. Initially, I built this rocket stock, me bucko, accordin' t' t' directions (almost), with t' exception o' usin' epoxy for all tube couplers, die cut rings, me hearties, and all stuffer tube/plastic rin' joints.

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

There was no mention o' fillets for t' fin t' body joint. Avast, me proud beauty! Obviously this is a must for any 24mm rocket. Don't forget it! I used epoxy versus t' usual plastic cement recommended by Estes for plastic/paper joints. Arrr! Secondly, shiver me timbers, 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. Well, blow me down! Ahoy! This gave t' stuffer tube a 3 point anchoring. 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. These would make this kit last longer than 5 flights on Estes D motors and others that would make it a staunch, matey, crowd pleasin' mid power flyer on other 24mm options like Aerotech E15, E30, F24, shiver me timbers, me bucko, F40.

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

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

Construction/Finishin' ratin' is a 3½. Arrr! Blimey! This is largely due t' t' potentially high price o' this rocket versus t' instruction error and t' cheesy stock finish option. Begad! Blimey! Additional mods are also required for a sturdy, 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. Begad! Begad! 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, me finished Maxi Alpha 3 weight be 10 oz versus t' 7.5 oz quoted on t' package. Begad! I find it hard t' believe that t' epoxy glue, matey, epoxy fillets, arrr, arrr, me hearties, and added paint I used, me hearties, accounts for all that difference. Well, blow me down! However, 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. Arrr! T' flight profile on t' D12-3 is flat out awesome. Aye aye! Begad! It has a slow majestic lift off. T' very straight, matey, stable flight deploys a chute at apogee. Avast, me proud beauty! 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. 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, arrr, 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, arrr, matey, 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, but if you push a couple squares into t' end o' t' stuffer tube it's nay too bad. Begad! Ya scallywag! 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. Avast, me proud beauty! So, I now fly in on a nylon 30" chute with a small spill hole. Ahoy! Now comes t' bad news. Avast, me proud beauty! T' Estes standard ¼" elastic cord attached t' t' centerin' rin' lasted t' typical quota o' 5 flights prior t' breaking. Begad! This has been replaced with 24" o' 150# Keelhaul®©™ and 36" o' 3/8" elastic with snap swivels. Blimey! T' Keelhaul®©™ is glued t' t' body tube wall. Arrr! If you haven't built this kit yet, 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, I am extremely satisfied with this kit. Ahoy! T' flight profile is great. Ya scallywag! 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. Ahoy! Well, blow me down! T' extra weight also did nay effect it's flight on t' D12-3. Avast, me proud beauty! Yes, shiver me timbers, now t' hoss weighs 11 oz! It would be perfect rocket had Estes nay made some compromises on t' design. Begad! Ahoy! T' weight could be less if balsa fins were used with a through t' wall attachment. A Keelhaul®©™ and 3/8" elastic shock cord with a combined length o' about 5 feet is a must. Ya scallywag! Also, me hearties, 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. It's been OOP for about 3 years. It was a re-release of the original 1979 version. 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 ...
