Squirrel Works Firebird

Brief:
T' Firebird SST is a beautiful lookin' kit that has sat in me build pile for a while as I tried t' answer the question, "Can I do justice t' this?" T' answer, me hearties, as usual, is "not really" but I am close enough to give it a shot. Ahoy! Blimey! I picked it out as t' "next victim" before Easter, ya bilge rat, matey, arrr, opened it up, read t' directions and promptly got bogged down with work, family and such. 7 weeks later, I actually started with just a little bit o' build time.

Construction:
T' parts were all high quality and all present and accounted for. T' instructions were well written, me bucko, adequately illustrated and clear.

As is fairly common, construction begins with t' motor mount. Well, blow me down! A slit was cut for t' retainer hook. Begad! A thrust ring was glued into one end and some tape be wrapped around t' hook and tube.

T' next step called for one o' me small modifications since I don't like tri-fold shock cord mounts. Well, blow me down! Blimey! There are 2 centerin' rings. Well, blow me down! Blimey! I like t' use Keelhaul®©™® to connect t' t' motor mount. Begad! Ahoy! Usually, I do this by cuttin' a groove on t' inside o' t' forward centerin' ring, passin' t' Keelhaul®©™® through and then tyin' t' Keelhaul®©™® around t' tube. Ahoy! Ya scallywag! In a recent TRF thread, I read somethin' that made me reconsider. It had t' do with locatin' the Keelhaul®©™® as far towards t' outside as possible t' maximize its life. Begad! That makes sense although thar be nay much difference in this particular case. I cut a notch in t' outside surface o' t' forward centerin' ring.

Squirrel Works Firebird Both o' me centerin' rings were a bit tight and would nay fit around t' motor tube without some sandin' o' t' inner surface. Ahoy! When t' surface be sanded enough, me hearties, matey, they were slid into place and glued with yellow glue. Begad! I then tied t' Keelhaul®©™® around t' tube and aligned it with t' notch. Avast, ya bilge rat, me proud beauty! A test fit told me that it would fit. Begad! I wanted t' be able t' get the Keelhaul®©™® to t' other end o' t' BT with a minimal amount o' fuss and use it t' help pull t' motor mount into place. Accordingly, I tied t' other end t' t' eye screw provided with t' kit. Blimey! That let it slide t' t' other end just fine and it was time t' glue t' motor mount in place. Well, blow me down!

I used a swab t' apply t' yellow glue inside t' BT. Blimey! I then dropped t' eye bolt and Keelhaul®©™® through and recovered them safely on t' other side. Well, blow me down! Ahoy! Now, with t' Keelhaul®©™® aligned with t' notch, matey, it was time t' feed t' motor mount into t' BT with gentle tension on t' Keelhaul®©™® to keep everythin' aligned. Blimey! It was a bit o' a tight fit so I needed t' apply a bit more tension on t' Keelhaul®©™®...OOPS!

I pulled too hard and t' whole thin' went in too far. Way too far. My finger could nay reach far enough in to grip t' motor mount and I looked desperately for somethin' t' push with from t' other side before t' glue set up. Everythin' in sight seemed t' be too short or too fat. Avast, me proud beauty! Avast! In deepenin' desperation, matey, I got up and looked around. My careless wife had left a wooden kitchen spoon layin' in t' dryin' rack and that seemed t' be just t' ticket. I put it in from t' forward end, me bucko, arrr, but t' handle was too short. Begad! Ya scallywag! T' spoon part hit t' end o' t' BT just as t' end o' the handle made contact. I withdrew it knowin' that I only had a few moments t' spare t' look around for somethin' else. Begad! Ahoy! I noted absently that I would need t' shipshape a bit o' glue off t' handle before t' wife notices it...but dried yellow glue might be passed off as hardened scrambled eggs. Well, blow me down! What did she feed t' kids that morning?

In t' race against time as I balanced domestic tranquility with t' precarious state o' me precious rocket, matey, the rocket won o' course. Several drawers later I found a long length o' 1/4" aluminum tube Gracie had thoughtfully hidden for me when I forgot t' put it away and it just manage t' push t' motor mount back t' other way. Avast, me proud beauty! Begad! T' glue was fairly stiff but I got it moved.

With great satisfaction, arrr, shiver me timbers, I returned t' aluminum tube t' a place o' me choosing. Avast! I remembered t' wipe off the yellow glue/hardened scrambled cackle fruit from t' spoon handle and sat back with a sigh.

T' next step was t' cut out t' wrap around fin guide and transfer t' lines onto t' BT. Blimey! That be easy enough and t' lines were lengthened with t' help o' a door corner. Avast! Blimey! Remember t' align t' proper line with t' motor retainin' hook.

T' instruction would then have had me t' glue on t' wings t' t' BT but t' BT was otherwise occupied allowing its glue fillets with t' engine mount t' dry so I skipped ahead. T' wings have drop down pods that are formed by gluin' a balsa oval t' both side o' a central balsa oval which integrate a mountin' root. I decided t' go ahead and assemble these so that they might be ready t' glue t' t' wings. Blimey! Well, matey, blow me down! They went together easy enough and were o' uniform size so t' sandin' needed t' shape them was minimal. Ya scallywag! A simple layer o' yellow glue was applied and then t' oval was pressed into place. Blimey! Avast, me proud beauty! T' process was repeated on t' opposite side and then all was repeated with t' other pod. Ahoy! I ensured that t' edges were aligned, shiver me timbers, matey, laid t' assemblies flat, me bucko, and set them aside t' dry.

T' wings were ready t' be installed. Accordin' t' t' instructions, they should have actually gone on prior to the previous step but now I was ready. Avast! Begad! Blimey! I decided t' install them with CA. I figured that I had a better chance of keepin' them straight if they hardened into position quickly. Begad! I used t' lines I had transfered onto t' BT for alignment and me deadlights t' ensure straightness. Ya scallywag! T' result was nay too shabby.

When t' wings had sufficient time t' stiffen up, t' win' pods were installed. Begad! Ya scallywag! While they would look find t' my eye hangin' at a right angle, that is nay t' way they are intended t' hang. They are intended t' have a bit o' an angle t' them. Ya scallywag! T' get t' correct angle, matey, a paper jig is provided. Avast, me proud beauty! It is simply cut out and set against t' win' and the pod root t' make sure everythin' is at t' correct angle. Ahoy! Begad! Again, I used CA t' be sure everythin' set up at t' correct angle while I be still attentive t' such things.

T' kit has two smallish fins that are t' be located on t' ventral surface, me bucko, spaced betwixt t' launch lug and the wings. Ahoy! Avast, me proud beauty! Blimey! Followin' t' instructions exactly would mean that they are installed and then have their leading, me bucko, outer, and trailin' edges rounded. Aye aye! That seemed t' me t' be an invitation t' disaster so I sanded t' contours in first.

Squirrel Works Firebird It should be noted that t' same procedure is indicated for t' wings. Begad! Arrr! I installed them first and rounded them later. Begad! Begad! It makes a bit more sense in that case so that t' pods can be dealt with in and accommodated in t' sandin' process. So at this stage o' me build, t' wings remained unshaped. Avast, me proud beauty! Begad! I will take care of that at a later time, after t' wings and pods are filleted.

I filleted t' wing/BT and Wing/pod seams with yellow glue. Begad! Then reluctantly, ya bilge rat, arrr, I put it away for t' night.

When I began work again, me bucko, t' first task I tackled was t' round t' edges on t' wings. Aye aye! Blimey! Blimey! This be done with a combination o' sandpaper and a sandin' stick. Arrr! It was more difficult than I thought it would be. Ahoy! Some o' t' dried glue from t' filletin' process made even removal o' material problematic. Ahoy! Aye aye! Blimey! Also, arrr, me hearties, sandin' t' narrow parts on t' forward tips o' t' wings where they attach t' t' BT was difficult. I finally gave up on that part.

T' next thin' t' be done was t' attach t' two little fins on t' ventral surface. Begad! I had already rounded them and they were easily put in place with some CA.

With t' fins in place, me bucko, matey, I turned me attention t' t' tail. It comes in 2 pieces. Blimey! Blimey! Ahoy! Blimey! There is a main body and a long angular fairing. Well, blow me down! Blimey! Both were glued into place with some CA. Avast! Blimey! Avast, me proud beauty! Blimey! T' main portion was done first and checked by eyeball for the correct angle and then t' fairin' be put in place. Begad! Blimey! Arrr! Blimey! Make sure that t' two pieces align correctly and are flush with one another.

T' kit is supplied with a wooden dowel that goes on top o' t' tail assembly. Avast, me proud beauty! T' ends o' t' dowel need t' be rounded. Aye aye! I used sandpaper and a sandin' stick, rotatin' t' dowel with a changin' angle until it be passable. Ya scallywag! Begad! If I was still practicin' structural engineering, me bucko, matey, I would call Mr. Begad! Magness and ask about t' species o' wood. Arrr! Well, shiver me timbers, blow me down! I specialized in heavy timber construction and this stuff be hard and durable. Begad! Blimey! It may have really been A36 steel with simulated wood grain. Begad! Avast! I am nay a practicin' engineer anymore, shiver me timbers, however, matey, so I just disgraced myself as a man o' t' cloth with me strong epithets.

After t' dowel was shaped, it too was put in place on top o' t' tail fin with a bead o' CA. Begad! Make sure you get it on straight. That will be important in t' next step. Begad! Avast! I was careless. Begad! Arrr! T' dowel went on straight but favors one side a bit more than t' other. Avast! Ya scallywag! I guess it rolled t' t' side a fraction. I owe another act o' contrition for t' repeated strong language.

With t' dowel more or less in place, I turned t' rocket over in its cradle and filleted t' fins. Begad! I let them dry overnight before tacklin' t' other side.

T' next step be t' work on t' horizontal stabilizers o' t' tail assembly. Avast! Avast! Unlike in previous steps, arrr, matey, the instructions here say t' round t' leading, me hearties, trailin' and tip edges before installing. Begad! That be easily accomplished with a sandin' stick. Blimey! Puttin' them on be a bit more difficult.

Because I had managed t' make a bit o' a blunder with t' installation o' t' rod on t' vertical stabilizer, shiver me timbers, I had t' make some compensations. Ahoy! Arrr! T' rod is straight, fore and aft, me bucko, but is a little bit more on t' starboard side than the port. Aye aye! T' horizontal surfaces are mounted t' t' rod and canted a bit. Aye aye! I had t' dry fit things several times to find out what t' best compromise was.

T' kit provided a cardstock alignment jig t' cut out and use t' get t' proper angle. Avast, me proud beauty! Begad! I am indebted t' Squirrel Works for this. Blimey! It made t' process go easier than otherwise would have been t' case. I put some CA on t' root edge and eyeballed it into place on t' rod. While it still had some play, I used t' jig t' get t' angle right. Aye aye! When it had set up, I did t' same with t' other side.

T' forward canards were handled in much t' same way as t' horizontal stabilizers but were much simpler. They were cut from t' balsa, t' leading, trailing, arrr, me hearties, shiver me timbers, and tip edges were rounded, matey, and they were glued into place with CA along t' lines extended from t' wings. Alignment be by eyeball.

While t' canards were settin' up, matey, I tied t' elastic shock cord off t' t' Keelhaul®©™® and tied t' other end t' t' screw eye inserted into t' nosecone. T' screw be held in place with a dab o' yellow glue.

I then judged that things had progressed far enough for me t' fillet t' dorsal surfaces o' t' canards and horizontal stabilizers. Avast, me proud beauty! This was done with yellow glue. I put t' model back into its cradle and t' waitin' game began again before can do any more work on it.

I began t' next build session by rememberin' that I had completely forgotten about t' launch lug. Arrr! Blimey! A single 1/8" lug is provided. Avast! T' instructions directed me t' cut it in half and glue t' pieces along t' line I had marked on t' ventral surface. Avast, me proud beauty! This was accomplished with t' expedient o' a short piece o' 1/8" rod t' keep the pieces aligned.

T' only other thin' accomplished in this build session was t' fillet t' undersides o' t' canards and horizontal stabilizers. Begad! This was done with yellow glue. Avast, me proud beauty! Arrr! Givin' that a chance t' set up paves t' way t' begin finishing.

Finishing:
Finishin' began with t' application o' a layer o' Elmer's filler. Ya scallywag! Based upon me experience and things I have read, I suspect that I may nay have been thinnin' it with enough water. Begad! T' application I used on t' Firebird was much wetter than is usual for me.

I liked t' thinner Elmer's. Well, blow me down! I devoted an evenin' t' sandin' it down as best I can and am rather pleased at the results. If I had a few more tools with which t' reach t' hard places, and this model has many, matey, I think it would have been even better. As it stands now though, I am well pleased.

I sprayed on a coat o' Kilz primer and let it dry. Begad! Ahoy! A few hours later, arrr, I sprayed on another coat. Avast! In doin' so, I was able t' see some sandin' imperfections that escaped me before. Begad! Still, it is one o' me better attempts. Begad! Ya scallywag!

After sprayin' in t' mornin' and just before noon, I brought t' Firebird inside for another round o' sandin' in the evening. Ya scallywag! I wet sanded with 320 grit sandpaper and that removed most o' t' blemishes that had bothered me earlier. I was satisfied enough t' be ready t' paint t' next day.

After t' primer be dry, shiver me timbers, I sprayed t' entire model with Krylon gloss white. Well, me hearties, blow me down! That made it look white, shiver me timbers, only more so than before. Avast! Aye aye! It be an improvement over t' mottled primer/sealer/fingerprints but it did nay really stand out. For that, I needed t' yellow.

I am nay a big fan o' yellow but I sure like t' way it looked on t' facecard. Blimey! Avast, me proud beauty! Nay havin' any on hand, I went back t' Home Depot t' discover that t' yellow selection be limited. Ahoy! There were plenty o' designer shades, me bucko, shiver me timbers, me hearties, usually pastel, me bucko, goin' for 8 or 9 dollars a can. Besides that, thar was just a single can o' House Brand, me hearties, bargain basement gloss yellow for $1.99 a can. Blimey! Ahoy! Since I liked t' looks o' t' bargain basement lid better than any o' t' designer ones, I went with that.

I also decided t' try t' Frog maskin' tape mentioned earlier in this thread. It is expensive but I am now a believer and will never go back. It went on easily and t' edges seemed t' know they were supposed t' stay down. Ahoy! Avast! It aligned easily and had an uncanny knack for knowin' when I wanted it t' stick and when I didn't. T' top half was masked off and a bit o' aluminum foil was used t' cover t' tail assembly. Well, blow me down! I then gave t' yellow a try.

Squirrel Works Firebird A few hours later I peeled off t' tape be was flabbergasted. Blimey! T' lines were perfect. That usually means I peeled up some o' t' underlyin' paint but that was nay t' case this time. From now on, I'm usin' Frog tape.

T' paint results were t' be considered a miracle until t' real miracle occurred. Begad! Ya scallywag! She who must be obeyed, otherwise known as me lovin' wife, shiver me timbers, shiver me timbers, Gracie, matey, actually said it looked good. Begad! She had never done that before.

Where this model falls down for me is in t' decals. Arrr! Avast! This is nay Squirrel Works' fault. Avast, me proud beauty! It is strictly me own.

Some very nice waterslides are provided and things started off well. Avast! I just had t' get t' tail logo on so that went on first. Avast! So far, so good. Arrr! Addin' t' cockpit be also easy. Ya scallywag! Arrr! Feelin' cocky, matey, I decided t' do t' hard part next.

T' hard part consists o' t' stripin' along t' sides. Blimey! Blimey! On t' nosecone, arrr, this consists merely o' a black line that is superimposed on t' line betwixt yellow and white. Avast, me proud beauty! Aft o' t' NC, me hearties, me bucko, t' same black line is present but thar is the added complication o' windows and hatches. Arrr! Each side o' t' rocket is intended t' be done with three decals.

T' NC line on t' port side went fine. Avast, me proud beauty! Then tragedy struck in t' form o' me evil cat, Jezebel. Aye aye! Without going into details, first o' t' big window sections be destroyed.

At that point, I bewailed me fate on TRF and tried t' buy another set o' decals. Blimey! In this I was unsuccessful. Don Magness, t' proprietor o' Squirrel Works was sympathetic t' t' depredations o' satanic cats and would nay sell me a replacement. Instead, ya bilge rat, he gave them t' me. Aye aye! Arrr! More than that, he sent 2 sets. Avast, me proud beauty! Little did I know how much I would need them.

When I got back t' work, arrr, I warmed up by puttin' on t' aileron decals first. Avast! Blimey! Avast, me proud beauty! Blimey! Then it was time t' get down to business with t' striping. I cut out t' middle section o' t' port side and placed it in t' water without thinking. When I removed t' decal from t' water and tried t' place it, matey, shiver me timbers, I realized me mistake. T' black line has t' sit right on t' line betwixt t' yellow and white paint. Arrr! Blimey! Avast! Blimey! Also sittin' on that line are wings and t' forward canards. I had left too much material on t' decal for it t' fit. Ya scallywag! Blimey! I tried correctin' things but wound up ruinin' t' decal.

I be horrified. Arrr! Blimey! Aye aye! Blimey! Luckily, arrr, Don Magness had a premonition o' me meager skills and sent an extra set. Ahoy! Blimey! Begad! Blimey! I now only had one set left. Avast, me proud beauty! Blimey! I decided t' cut t' decal into several shorter and more manageable pieces, rememberin' t' trim as close as possible t' t' black line.

Squirrel Works Firebird By and large, shiver me timbers, this process worked for me, matey, matey, matey, especially on t' starboard side which looks pretty good. T' port side looks less good, shiver me timbers, me hearties, particularly over t' forward canard. At this point, me hearties, t' decal "gripped" before I be finished placin' it. Aye aye! Ahoy! T' result is a slightly curved set o' windows over t' canard. Avast! Begad!

Let me emphasize 2 things. Aye aye! Well, blow me down! T' problems I had were entirely due t' me and an evil cat. Ahoy! Also, Squirrel Works rose above t' call o' duty in customer relations. Arrr!

T' end result looks good, me bucko, me bucko, especially when viewed from t' "good side".

I decided that I wanted t' do one more thin' before applyin' t' Future Floor Polish. Well, blow me down! T' motor tube looked kind of sad with t' top bein' a cloudy white and t' bottom bein' a splotchy yellow. Ahoy! I decided t' paint it a metallic bronze. With that done and dry, me bucko, t' whole thin' got a couple coats o' future and it be deemed ready t' fly.

Construction Rating: 4 out o' 5

Flight and Recovery:
T' day o' t' maiden flight dawned hot...as in hellfire and brimstone, but nothin' was goin' t' deprive me o' my first launch window in a long while. My first rocket was t' Firebird conservatively powered with an A8-3. Ahoy! It looked pretty good sittin' on t' pad and it looked even better headin' up. It got up a fair ways and t' chute deployed perfectly. Aye aye! Comin' down was nay too shabby either. Avast, me proud beauty! Avast, me proud beauty! In fact, I thought things had gone perfectly until I took a closer look. Ahoy! I had broken off one o' t' horizontal stabilizers on landing.

Squirrel Works Firebird T' part be found and it is an easy fix but it prevented me from launching this one any more today.

PROs: good flier

CONs: none

Flight Rating: 4 out o' 5

Summary:
I think this is one o' t' best lookin' rockets Squirrel Works has t' offer. Arrr! Blimey! It is a bit challengin' but well within the capabilities o' anyone who has built a few already. Aye aye! I am lookin' forward t' keepin' this one around for a while.
