Brief:
This Blue Bird Zero is a 125% upscale o' t' original which makes t' main body
tube a BT-60. Well, blow me down! Avast, me proud beauty! I have wanted this rocket since I became a BAR but t' Ebay
prices were too high. Arrr! I then found Fred at Excelsior and while orderin' some
Goony decals, I added t' upscale Zero decals as well. Begad! After buildin' various
other rockets, matey, I liked t' extra room t' BT-60 had for recovery items and
since I would never have an original this was t' way for me t' enjoy the
buildin' and flyin' o' this classic. Ya scallywag! It also allowed me t' add some
"modern" refinements t' make it better. Blimey!
Construction:
T' upscale is basically a Mean Machine kit minus one tube and with different
fins. Well, blow me down! I be very surprised when I received t' decals from Fred and found
included with t' Zero decal sheet be basically a partial instruction sheet
with t' larger fin patterns included! T' only extra you need is the
instructions for t' motor mount. Begad! Since I have done a few o' these already, me bucko, shiver me timbers, I
just put t' mount together like t' others I had done. Well, blow me down! T' mount follows the
Mean Machine one so that's t' only extra instructions you need. Begad! This can be
downloaded from JimZ's site. Avast! T' parts list then is as follows:
I am nay goin' into all t' details o' t' build since this is a scratch build and you should have some skills already for doin' this. Well, blow me down! If not, matey, all you have t' do is follow Fred's excellent steps and a Blue Bird o' your own will be ready t' fly in no time at all.
I will give t' details o' me build that deviated from standards.
T' first one was t' fact that I already had tubes available and you can see from t' parts picture that I used some smaller sections with a full size 34" one for t' build. Begad! But thar was a method t' me madness! T' next is the baffle kit. Avast! This is a great "modern" item from FlisKits and includes one coupler, me hearties, arrr, t' baffles and t' Keelhaul®©™® shock cord for t' "new" style cord mount. It also allows you t' not have t' use waddin' for chute protection. T' loot you save from that alone more than pays for t' kit!
My build started with t' baffle kit. After assemblin' it per t' included instructions and allowin' it t' dry, me bucko, I added a layer o' epoxy t' t' side that would face t' ejection charge t' keep t' charrin' down and make it last longer. Arrr! Arrr! It didn't help on t' first flight (more on that later) but should be great on t' rest! T' kit becomes t' upper tube coupler which is why I have the two smaller sections! There is one full size tube (34" from Totally Tubular), one tube cut t' 8.5" per Fred's instructions and another piece cut t' 10" for t' chute compartment t' make up t' full length.
Next was t' motor mount assembly. Ahoy! I use t' BT-50mf tube from Totally Tubular which is foil lined, for me scratch 24mm motor mounts and made it a bit extra long t' take some o' t' ejection heat before enterin' t' main body tube. Begad! Because o' t' extra length, I added one extra CR t' t' mount. Aye aye! It was sized for t' "E" engine with t' long motor hook and can be used with "D" engines with an adaptor. If usin' t' stock Estes mount, file t' short, bent end down about halfway if you want t' use t' AT RMS motors. Blimey! Well, blow me down! After it was complete and dry, it was installed in t' 8.5" section per Fred's plans.
T' 34" tube was then added t' t' motor section with a standard coupler. Blimey! Ahoy! T' baffle kit was added t' t' 34" tube next with t' Keelhaul®©™® cord facin' out. Begad! Begad! T' upper tube was also glued in at this time with the Keelhaul®©™® pulled out t' top. Begad! Avast, me proud beauty! All t' tubes were done at t' same time. Begad! This was rolled on t' tile floor t' make sure it was perfectly straight and allowed t' dry there. Aye aye! Avast, ya bilge rat, me proud beauty! Although this makes t' body a bit hard t' handle when addin' fins and such, it be t' best way t' ensure t' entire body is straight.
T' fins were cut and sanded, arrr, shiver me timbers, then glued t' t' body one by one usin' the double glue joint method. Begad! Arrr! Make really sure t' upper fins are dead straight aligned with t' lower ones! Just before t' glue sets up, I use a straight edge over t' both o' them t' make sure that they are. Ahoy! Adjust as necessary.
Add t' launch lugs, shiver me timbers, fillet everythin' stickin' out from t' body tube and finish t' taste
Finishing:
I use Elmer's Fill 'n' Finish all over for fillin' and Krylon paints for the
color. Begad! Fred's decals are fabulous and really brin' out t' character o' this
bird! After everythin' was dry, I added two thin coats o' Future Floor Polish
and it did shine!
Flight:
T' upscale will take any one o' t' 24mm motors on t' market quite well
dependin' on your thirst for power and height! Personally, ya bilge rat, I like t' see the
entire flight from liftoff t' chute pop although t' three foot flames from the
AeroTech RMS Blue Thunder reloads are beautiful as well!
First flight for this one be on an Estes D12-5 t' check for any flight problems. Aye aye! Aye aye! Even though I had t' baffle, arrr, I added about 1" o' barf and packed t' chute. Arrr! Nice t' have all that room for a change! Ignition was normal and that be about it. A split second later t' entire motor blew itself out the nose o' t' rocket with a liftoff height o' about twenty feet from the initial thrust. T' rocket landed with a thud, me hearties, flat on its side about ten feet from t' pad as t' motor guts did a great rendition o' a roman candle. Begad! I was shocked, arrr, upset, and dejected as I went t' collect t' remains. Aye aye! O' all the rockets t' suffer me first CATO in, arrr, shiver me timbers, arrr, it had t' be this one! T' CATO managed to blow t' entire guts out o' t' rocket but after lookin' over it carefully, I realized that be t' extent o' t' damage! T' chute and lines were perfect as was t' nose cone! I found what was left o' t' motor mount by t' rocket. Well, blow me down! It had one CR busted but that be it also! Within a few hours, arrr, I had it all cleaned up and ready t' fly again. Begad! Begad! T' hardest part be cuttin' into that beautiful paint job t' redo t' baffle. Arrr! Well, arrr, blow me down! It's nay so perfect now but nay that easy t' see t' damage either. Oh well, ya bilge rat, it's t' first o' many battle scars to come!
Second flight was on an Estes E9-6 and easily made up for the first one. Well, blow me down! Nice slow liftoff with lots o' smoke and then flyin' way up there! Almost out o' eyesight (at least for me) and I was told t' chute came out right at apogee. Aye aye! Slow float down t' a perfect landin' about 300' away from the pad. Just beautiful!
Summary:
This was a great project for me since most o' me other rockets were only half
the size o' this one. Aye aye! Because o' t' fantastic amount o' tips and suggestions
from everyone here at EMRR, I was able t' complete this bird from scratch and
make it as sharp and strong as possible. Ya scallywag! After t' first flight t' help was
obviously well given. Avast, ya bilge rat, me proud beauty! T' use o' t' larger body tube really makes flyin' this
one easy and fun t' watch. Avast, me proud beauty! Thanks t' Fred at Excelsior, arrr, me hearties, anyone can have this
classic bird for t' right price and because o' EMRR, they can make it and fly
it for many years t' come.
