Then thar's THE Fat Boy. Begad! Blimey! Maybe nay t' original, shiver me timbers, but Estes be t' one that trademarked t' name. Begad! Blimey! This be t' third 2.6" sport kit that I have reviewed for comparison sake. Begad! Begad! Blimey! T' Fat Boy be t' shortest o' t' kits reviewed, shiver me timbers, me hearties, bein' only 12.9" tall and weighin' 3 ounces. Well, arrr, blow me down! 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). Avast, me proud beauty! Its 18mm motor mount comes with 1/32" die-cut cardboard centerin' rings and a motor retention clip. Ya scallywag! It uses 3/32" die-cut balsa fins with through-the-wall mounting. Blimey! 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. 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, matey, finishin' and preparation for flying. Begad! Aye aye! T' instructions are in a logical order and could get a new modeler through t' kit assembly. Well, blow me down! This bein' t' case, merits it's Beta Series (level 1) rating. Blimey! Aye aye! Blimey!

There is nay a lot t' say about assembly because it be so straight forward, however, me hearties, me hearties, just a few comments about a couple o' steps and observations. Begad!

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

T' instructions were also clear in describin' t' use o' balsa filler on t' fins and in t' paint scheme. 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. This decal is nay large enough t' do this. Ahoy! Begad! T' package and catalog pictures t' decal accurately.

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

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

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

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

Overall, me bucko, arrr, ya bilge rat, for CONSTRUCTION I would rate this kit 4 1/2 points. Well, ya bilge rat, blow me down! It would be nice t' see Estes go t' a different shock cord mount instead o' t' three-fold paper method. Blimey! Other than t' misfit o' t' through-the-wall fins, shiver me timbers, construction be straight forward. Ya scallywag! Avast!

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. Ya scallywag! Well, blow me down! This fact made me miss two launch shots! However, in similar wind conditions both rockets display a lot o' weather-cocking. Blimey! Aye aye! Both flights usin' C6-3's were parallel t' t' ground before apogee. Ahoy! Avast!

T' first flight was 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. Well, blow me down! Well, blow me down!

T' second flight, shiver me timbers, me bucko, went much further out due t' weather-cocking. After about 200 yards, t' parachute ejected and t' rocket dropped nearly straight t' t' ground. Blimey! Ahoy! I had "reefed" t' parachute by tapin' t' shroud lines about 5" down from t' chute.

T' parachute, shroud lines and shock cord system all demonstrated performance and showed no sign o' wear or damage. Ahoy! Avast, matey, me proud beauty! Blimey! There be a small black spot at t' top o' t' body tube which wiped away easily. Aye aye! Blimey!

For FLIGHT/RECOVERY, I would rate this kit 4 1/2 points. Avast, me proud beauty! Avast, me proud beauty! I think an 18" parachute is too large for this kit. Arrr! Well, shiver me timbers, blow me down! It needs a smaller chute or recommendation for a spill hole or reefing. Ya scallywag! 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. Aye aye! Ahoy!

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

  • 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, ...
