Then thar's THE Fat Boy. Arrr! Blimey! Maybe nay t' original, arrr, but Estes be t' one that trademarked t' name. Arrr! This be t' third 2.6" sport kit that I have reviewed for comparison sake. Ahoy! Blimey! T' Fat Boy be t' shortest o' t' kits reviewed, bein' only 12.9" tall and weighin' 3 ounces. Avast, me bucko, me proud beauty! See me 2.6" Stubby Rocket Comparison Page

T' kit comes with an 8" single body tube and 3.875" plastic nose cone (the remainin' inch in height is from t' fin sweep). Aye aye! Aye aye! Its 18mm motor mount comes with 1/32" die-cut cardboard centerin' rings and a motor retention clip. Aye aye! It uses 3/32" die-cut balsa fins with through-the-wall mounting. It comes with an Estes' standard 18" plastic parachute, a 24" elastic shock cord (1/4" flat) which attaches via t' Estes' standard three-fold paper mount. Avast! Begad! It also includes a single launch lug and a decal sheet.

CONSTRUCTION:

There are six pages o' instructions which are heavily illustrated and very clearly defines t' steps o' construction, finishin' and preparation for flying. Well, blow me down! T' instructions are in a logical order and could get a new modeler through t' kit assembly. Well, blow me down! Blimey! Blimey! This bein' t' case, merits it's Beta Series (level 1) rating. Well, blow me down! Avast! Blimey!

There is nay a lot t' say about assembly because it was so straight forward, arrr, however, just a few comments about a couple o' steps and observations.

T' first was t' assembly o' t' through-the-wall fins. Ya scallywag! Blimey! Blimey! Here t' fins are t' fit into t' pre-cut slots in t' body tube. These did nay fit and required extendin' each slot about 1/8" toward t' aft o' t' rocket. Ya scallywag! Begad! Blimey! On t' positive side, t' fins were arranged so that t' grain was parallel t' t' leadin' edge which improves strength. Avast, me proud beauty!

T' instructions were also clear in describin' t' use o' balsa filler on t' fins and in t' paint scheme. Avast! Blimey! There be one illustration that was nay accurate describin' t' application o' t' decals. Begad! In t' illustration, it shows t' decal which spells out "FAT BOY" bein' applied on t' body tube and crossin' over onto t' nose cone. Ya scallywag! Ya scallywag! This decal is nay large enough t' do this. T' package and catalog pictures t' decal accurately.

Two changes where made t' t' recovery system. First, matey, instead o' t' three-fold paper mount, a short piece o' Keelhaul®©™ was attached t' t' thrust rin' and t' elastic shock cord be tied t' it at about t' same position t' paper mount would have gone. Arrr! Secondly, me hearties, an 18" purple rip-stop nylon parachute be used. Aye aye! Blimey! Estes' parachutes work fine, ya bilge rat, however, nylon chutes are better t' prevent stickin' and are more durable all around. Ya scallywag!

[Picture]For finishin' I tried a couple o' different tactics than previous kits. I saw a note on t' RMR newsgroup suggestin' usin' plain ol' Elmer's Glue as a balsa fin filler. Avast! I did this and it worked out quite well. Ahoy! Begad!

On top o' that, me hearties, I used Walmart's primer this time. Blimey! This stuff does nay sand nearly as well as Plasti-Kote's primer. Avast! Blimey! I will revert back t' usin' Plasti-Kote primer for fillin' and Walmart's primer as t' final coat (when usin' Walmart's paint). Arrr!

Once I finished smoothin' and priming, an application o' $0. 98 Walmart enamel be added. This time a baby blue. Well, shiver me timbers, blow me down! After dryin' a day, t' decals were applied. Arrr! T' decals are self-adhesive and are very shiny. Well, me hearties, blow me down! T' ensure consistency o' finish and protect t' decals a bit (not as necessary on self-adhesive decals), matey, apply a coat o' clear finish. Blimey! I followed up with Walmart's Clear enamel. Aye aye! (additional comments about Walmart paint)

Overall, for CONSTRUCTION I would rate this kit 4 1/2 points. Well, blow me down! It would be nice t' see Estes go t' a different shock cord mount instead o' t' three-fold paper method. Begad! Begad! Other than t' misfit o' t' through-the-wall fins, construction was straight forward. Aye aye!

FLIGHT/RECOVERY:

T' Estes Fat Boy isn't as "heavy" as t' Vaughn Brothers Blobbo and can get off o' t' pad a bit faster. Avast! Ahoy! This fact made me miss two launch shots! However, matey, in similar wind conditions both rockets display a lot o' weather-cocking. Blimey! Both flights usin' C6-3's were parallel t' t' ground before apogee.

T' first flight be t' higher o' t' two test flights and t' wind carried t' rocket about 100 yards from t' launch pad after flyin' about 100 yards in t' opposite direction due t' weather-cocking. Begad! Avast!

T' second flight, arrr, ya bilge rat, me bucko, went much further out due t' weather-cocking. Arrr! After about 200 yards, me bucko, t' parachute ejected and t' rocket dropped nearly straight t' t' ground. I had "reefed" t' parachute by tapin' t' shroud lines about 5" down from t' chute. Avast! Avast, me bucko, me proud beauty!

T' parachute, shiver me timbers, shroud lines and shock cord system all demonstrated performance and showed no sign o' wear or damage. There was a small black spot at t' top o' t' body tube which wiped away easily. Ya scallywag! Blimey!

For FLIGHT/RECOVERY, shiver me timbers, shiver me timbers, I would rate this kit 4 1/2 points. I think an 18" parachute is too large for this kit. Aye aye! It needs a smaller chute or recommendation for a spill hole or reefing. Blimey! I have seen others at t' range cut out t' center o' t' chute that says Estes on their Fat Boy kits so I assume they feel t' same way about t' descent rate bein' too slow. Begad! Avast, me proud beauty! Blimey!

Overall, shiver me timbers, this kit is very easy t' build and fun too fly. Blimey! I give t' kit an OVERALL ratin' o' 4 1/2 points. Aye aye!

  • Estes Fat Boy By Eric Miller

    I received a Estes Fat Boy as a Christmas gift from my wife Lisa. The Fat Boy is an Estes Beta (Beginner) series rocket. This kit was packaged in plastic with a cardboard picture of the rocket. It probably cost around $15.00. All the parts were included and none were damaged. I think Estes has some of the best instructions on the market (I like pictures). The kit contains a plastic nose cone, ...
