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. Aye aye! It stuck me as "primitive" and I do nay mean that in a derogatory manner. As someone said on YORF, shiver me timbers, matey, 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. Aye aye! 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. Aye aye! Blimey! They call for BT-3 tubing. Avast! Blimey! This was one I had nay worked with before. Avast! Blimey! T' only distributor I found for BT-3 was FlisKits (I like their stuff too), but then I realized I was in t' MMX department. Begad! Blimey! I checked t' diameter and realized that thar be no way I be goin' t' fit an 18mm motor into t' FlisKits BT-3. So it is that I posted a message on YORF askin' for help. Blimey! Blimey! T' kind folks thar soon gave me an answer I could use. Blimey! Blimey! Begad! Blimey! T' archaic BT-3 o' Estes was still available as t' Semroc BT-30. That bein' t' case, ya bilge rat, I place me order and had it two days later. Arrr! Blimey! Begad! Blimey!

My total parts list was as follows:

  • 1/16" balsa
  • 3.25" Semroc BT-30
  • 2.75" Semroc BT-30
  • Semroc BNC 30C balsa nosecone
  • 2 x 1/8" launch lug

After gettin' t' parts, they sat in t' box from 5 Nov until Christmas Day when I finally had time t' get started. When I did get started, shiver me timbers, I found a simple but fun project t' occupy an afternoon.

T' sustainer body tube was supposed t' be 3.125 inches long. Avast, me proud beauty! Blimey! I had ordered a 3.25" as t' nearest fit. Arrr! Blimey! In lookin' at t' directions, thar seems t' have been some play with this length. Avast! 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, t' first step was t' glue on t' nose cone with yellow glue.

While t' nose cone be drying, I cut out t' fin template and laid it on me 1/16" balsa stock and traced around it with a pencil. Begad! I then copied t' pattern twice more makin' sure t' grain be aligned as indicated. Ahoy! An X-Acto knife be then used t' cut t' fins out.

An Estes fin markin' guide be used t' mark t' body tube for 3 fins and t' tick marks were extended usin' a pencil and an angle. 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. Blimey! T' fins were then glued in place with yellow glue and a double glue joint.

As t' sustainer dried, I turned me attention t' t' booster. It called for a 2.75" length o' BT-30 and I did have one t' right length. Avast, me proud beauty! Avast! I marked t' fin lines as before and cut out t' booster fin template. T' outlines were transfered t' t' sheet balsa and t' fins were cut out. Well, blow me down! Begad! These were more difficult because o' t' curves. Well, blow me down! When I was done, I had t' stack t' fins and "regularize" them with some judicious sanding. Avast, arrr, me proud beauty! 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 bucko, ya bilge rat, somebody noticed that t' grain on t' fins was running the wrong way, ya bilge rat, matey, parallel t' t' BT, 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 be indeed on t' surface I used but lookin' at t' artwork, ya bilge rat, I saw that t' template was in error.

An X-Acto be used t' slice t' fins away as closely as I could come t' t' BT. I intended t' make new fins but I wanted t' see how close I could get. When they were off though, me bucko, 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. Blimey! 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. Begad! 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. Blimey! I waited overnight but I could see t' first fin was fairly dry before I had finished t' third. Avast, me hearties, me proud beauty! T' second nice thin' was t' resultin' uniformity. Only a light sandin' with #400 was needed t' be ready for primer.

I primed with Kilz. Two coats were applied and t' primer was allowed t' dry. Begad! Arrr! T' next day, t' sustainer was ready t' be primed and it got 2 coats o' Kilz as well.

While sandin' t' primed stages, I noticed a perennial mistake o' mine. Blimey! Blimey! Well, blow me down! Blimey! I had forgotten t' launch lug...again. Ahoy! Blimey! Begad! Blimey! I scraped off a bit o' primer and glued it on, givin' it a chance t' dry.

When t' lug had dried, me bucko, I painted t' BTs o' both t' sustainer and booster yellow. Blimey! Aye aye! T' yellow be given a day to dry and then t' rocket was masked t' paint t' NC and fins o' both stages orange. Arrr! Aye aye! Then it be just a simple matter of sprayin' t' orange on each stage.

T' final result was bright yellow and orange and, I hoped, easy t' see way up there.

Flight:
At least a half a year after I first got started on this one, it finally made its maiden flight. Aye aye! Well, blow me down! It had been taken out t' fly before but always somethin' went wrong. Blimey! Ahoy! This time, it would fly.

Estes DOM PeeWee T' start things off, shiver me timbers, I wanted t' try just t' single stage configuration with just a 1/2A6-2. I wanted to see how it would behave. I had spotters ready.

It took off fine and disappeared t' most people. It be reacquired when we heard t' motor pop. Blimey! Avast, me proud beauty! T' motor landed a few feet from t' flight line but nobody saw what happened t' t' rocket itself. Avast! Ya scallywag! We looked for a while and gave up and I thought I would be rebuildin' t' sustainer. Begad! Arrr! Near t' close o' t' day, though, matey, somebody found it while hunting for a mid power rocket. Ahoy! Blimey! 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, me proud beauty! Blimey! Blimey! Blimey! I taped t' motors together with cellophane tape and loaded them into t' rocket. T' rocket be then taken t' t' pad and hooked up. Blimey! Blimey! I asked all present t' help with t' tracking. Aye aye! Blimey! Aye aye! Blimey! On ignition, shiver me timbers, it started scootin' and looked pretty good doin' it. Well, blow me down! Blimey! Ya scallywag! Blimey! Everyone saw t' stagin' and t' booster tumblin' back to earth but t' sustainer was never seen again.

Recovery:
PROs: it flies nice.

CONs: It be nay recovered.

Flight Rating: 4 out o' 5

Summary:
This be an easy rocket t' build. Blimey! I had me problems with it but they were my problems. Avast! It also flies well...too well. Avast, me proud beauty! Avast! Without a smaller booster motor available, ya bilge rat, matey, matey, it is likely t' be lost, as mine was. Aye aye! Even in t' single stage configuration on a 1/2A, shiver me timbers, it really moved.

I will be rebuildin' t' sustainer but will make some modifications, lengthenin' it t' include a streamer.
