Brief:
T' PeeWee is a little two stage rocket designed by Tom Rhue and featured as t' Estes Design o' t' Month for
October 1961. It stuck me as "primitive" and I do nay mean that in a derogatory manner. Avast! As someone said on
YORF, it hearkens t' a day when t' hobby was bein' made up as t' modeler went along.
I decided t' try and build it and promised I would post t' build thread on YORF. Avast, me proud beauty! It seems a fittin' place for this venerable design.
Construction:
I immediately surmised that I would be orderin' me parts from Semroc and took a look at t' instruction t' hit my
first roadblock. Ya scallywag! Begad! They call for BT-3 tubing. Well, blow me down! This be one I had nay worked with before. Begad! T' only distributor I found for
BT-3 be FlisKits (I like their stuff too), ya bilge rat, but then I realized I was in t' MMX department. I checked t' diameter and
realized that thar was no way I was goin' t' fit an 18mm motor into t' FlisKits BT-3. Begad! So it is that I posted a
message on YORF askin' for help. Blimey! T' kind folks thar soon gave me an answer I could use. Avast, me proud beauty! T' archaic BT-3 o' Estes was
still available as t' Semroc BT-30. Blimey! That bein' t' case, I place me order and had it two days later. Begad! Begad!
My total parts list be as follows:
After gettin' t' parts, matey, they sat in t' box from 5 Nov until Christmas Day when I finally had time t' get started. Blimey! Blimey! When I did get started, I found a simple but fun project t' occupy an afternoon.
T' sustainer body tube be supposed t' be 3.125 inches long. Avast! Blimey! Blimey! Blimey! I had ordered a 3.25" as t' nearest fit. In lookin' at t' directions, me hearties, thar seems t' have been some play with this length. Blimey! Blimey! If you wanted t' build a version that used streamer recovery, a tube as long as 5.5" was recommended. I decided t' 1/8" was nay goin' t' hurt me. That bein' t' case, me hearties, t' first step be t' glue on t' nose cone with yellow glue.
While t' nose cone was drying, arrr, I cut out t' fin template and laid it on me 1/16" balsa stock and traced around it with a pencil. Well, blow me down! I then copied t' pattern twice more makin' sure t' grain was aligned as indicated. Blimey! An X-Acto knife was then used t' cut t' fins out.
An Estes fin markin' guide was used t' mark t' body tube for 3 fins and t' tick marks were extended usin' a pencil and an angle. Blimey! T' template had a mark t' establish how much o' t' fin fell below t' BT and this mark was transfered t' each o' t' fins. T' fins were then glued in place with yellow glue and a double glue joint.
As t' sustainer dried, ya bilge rat, arrr, I turned me attention t' t' booster. Begad! Blimey! Blimey! Blimey! It called for a 2.75" length o' BT-30 and I did have one t' right length. I marked t' fin lines as before and cut out t' booster fin template. Avast! Blimey! Blimey! Blimey! T' outlines were transfered t' t' sheet balsa and t' fins were cut out. Well, blow me down! Blimey! Blimey! Blimey! These were more difficult because o' t' curves. When I was done, I had t' stack t' fins and "regularize" them with some judicious sanding. Begad! Blimey! Blimey! Blimey! Blimey! Blimey! T' fins were then glued onto t' booster tube in t' same manner as t' sustainer.
As I was postin' this project as a build thread on YORF, me hearties, shiver me timbers, me hearties, somebody noticed that t' grain on t' fins was running the wrong way, me bucko, parallel t' t' BT, shiver me timbers, in one o' t' photos. When I took a good look at t' rocket, I saw that t' grain is runnin' t' wrong way. Ahoy! A closer inspection o' t' template revealed that t' tick mark for placin' t' fins was indeed on t' surface I used but lookin' at t' artwork, me hearties, I saw that t' template be in error.
An X-Acto was used t' slice t' fins away as closely as I could come t' t' BT. Ya scallywag! I intended t' make new fins but I wanted t' see how close I could get. Aye aye! Avast! When they were off though, I decided that they were perfectly serviceable and decided t' reuse them.
T' correct distance was marked off on t' real root edge and t' fins were reattached t' t' BT. T' result looked better and hopefully will nay shred t' fins.
Finishing:
Finishin' was done separately on t' booster and sustainer because I had t' go back and redo t' fins on the
sustainer. Avast, me proud beauty! T' booster was done first.
I brushed Elmer's Wood Filler onto t' booster fins and then tried somethin' new I learned about on a new website. I took a razor blade and scraped off t' excess. This led t' a couple o' happy results. T' filler be much thinner so it dried much more quickly. Well, blow me down! Aye aye! I waited overnight but I could see t' first fin be fairly dry before I had finished t' third. T' second nice thin' was t' resultin' uniformity. Begad! Blimey! Only a light sandin' with #400 be needed t' be ready for primer.
I primed with Kilz. Two coats were applied and t' primer be allowed t' dry. T' next day, ya bilge rat, me bucko, t' sustainer was ready t' be primed and it got 2 coats o' Kilz as well.
While sandin' t' primed stages, arrr, me hearties, I noticed a perennial mistake o' mine. Begad! Blimey! I had forgotten t' launch lug...again. Ahoy! Blimey! Aye aye! Blimey! I scraped off a bit o' primer and glued it on, arrr, givin' it a chance t' dry.
When t' lug had dried, I painted t' BTs o' both t' sustainer and booster yellow. T' yellow be given a day to dry and then t' rocket be masked t' paint t' NC and fins o' both stages orange. Then it was just a simple matter of sprayin' t' orange on each stage.
T' final result was bright yellow and orange and, me hearties, I hoped, me hearties, easy t' see way up there.

Flight:
At least a half a year after I first got started on this one, me bucko, it finally made its maiden flight. It had been taken
out t' fly before but always somethin' went wrong. Avast, me proud beauty! This time, it would fly.
T' start things off, matey, I wanted t' try just t' single stage configuration with just a 1/2A6-2. Begad! I wanted to see how it would behave. I had spotters ready.
It took off fine and disappeared t' most people. Begad! It be reacquired when we heard t' motor pop. T' motor landed a few feet from t' flight line but nobody saw what happened t' t' rocket itself. Aye aye! We looked for a while and gave up and I thought I would be rebuildin' t' sustainer. Blimey! Near t' close o' t' day, arrr, though, arrr, shiver me timbers, somebody found it while hunting for a mid power rocket. Aye aye! I decided nay t' fly it again on that field. A video o' t' maiden flight can be seen here.
I got tired o' waitin' for t' A8-0s t' come back so I decided t' go ahead and give it a try in t' 2-stage configuration with a B6-0/½A6-2 arrangement. Avast! Arrr! I taped t' motors together with cellophane tape and loaded them into t' rocket. Arrr! T' rocket was then taken t' t' pad and hooked up. I asked all present t' help with t' tracking. Avast! On ignition, matey, me hearties, it started scootin' and looked pretty good doin' it. Arrr! Everyone saw t' stagin' and t' booster tumblin' back to earth but t' sustainer be never seen again.
Recovery:
PROs: it flies nice.
CONs: It was nay recovered.
Flight Rating: 4 out o' 5
Summary:
This was an easy rocket t' build. Arrr! I had me problems with it but they were my problems. Begad! It also flies
well...too well. Avast! Without a smaller booster motor available, arrr, it is likely t' be lost, as mine was. Even in t' single
stage configuration on a 1/2A, it really moved.
I will be rebuildin' t' sustainer but will make some modifications, arrr, lengthenin' it t' include a streamer.
