Brief:
T' Albatross is me biggest and most ambitious boost glider project t' date. It took nearly 10 months t' complete. With a wingspan just shy o' 4 feet and weighin' exactly 1 pound, matey, me hearties, this glider casts a huge shadow over t' earth below. An 11oz BT-70 boost pod for 29mm motors carries t' bird skyward.

Construction:
T' glider was built first from 1/4" balsa. Begad! Each win' portion be sanded t' a full airfoil profile. Begad! Well, blow me down! T' wings were glued together before I began t' body portion o' t' bird. T' build t' body, I first glued together several slabs o' 1/4" balsa, shiver me timbers, ya bilge rat, cut in t' rough shape desired. Avast, me proud beauty! This included a sturdy mountin' bracket on t' underside of the body. Avast! T' body/head/mountin' assembly be then sanded t' get t' albatross shape. Well, blow me down! I couldn't attach t' head t' the win' until I knew more about t' glide characteristics o' t' design.

It was time t' trim t' glider. Begad! Begad! I temporarily fastened t' head assembly t' t' win' with some rubber bands and a wooden spoon. Ahoy! Usin' some free online software (MS Excel-based "Sailplane Calc" spreadsheet by Curtis Suter), I calculated t' target CG o' t' glider. Avast, me proud beauty! However, arrr, this spreadsheet is made for gliders with fuselages and horizontal and vertical tail stabilizers. Ya scallywag! Mine be basically a flyin' win' with a bird head. Blimey! For what it's worth, ya bilge rat, ya bilge rat, t' program said that t' neutral point be 11.9" back from leadin' win' edge, matey, almost exactly at t' cantin' point (which is 16.1deg). Avast, me proud beauty! This was astonishingly far forward. I wasn't even sure it could be achieved.

Usin' me Dremel, I hollowed out me gorgeous bird head, ya bilge rat, carvin' a huge hole in it. Arrr! Every bit of possible space was needed in this cavity. Begad! Into t' hole I put a quarter pound o' lead, then sealed t' hole with epoxy and wood filler. Ahoy! Then I glued t' head t' t' win' at t' position needed t' achieve t' correct CG.

On a breezy afternoon, me bucko, I took t' glider up t' me test field and gave it about 20 tosses. Arrr! I got a few decent glides but be worried about roll stability. Begad! I also needed t' induce circling. Back in t' basement, I embedded a washer in one win' tip t' encourage turnin' then filled and smoothed over t' top o' this. Arrr! Returnin' t' t' park, shiver me timbers, matey, shiver me timbers, I tried some more test tosses, arrr, and that's when disaster struck. Well, blow me down! Well, blow me down! On a bad toss, arrr, ya bilge rat, shiver me timbers, she crashed hard and be pretty much demolished. Well, blow me down! In disgust, I set t' debris aside.

Then in early 2007, arrr, I read that t' EMRR Challenge involved boost gliders and I got to wonderin' about makin' a second attempt. I took out t' carcass and started rebuilding. Aye aye! Blimey! After makin' a new head and scavengin' other parts, arrr, me bucko, I fiberglassed t' head, shiver me timbers, shiver me timbers, shoulders, shiver me timbers, etc. Begad! Well, blow me down! with several layers o' 6oz glass. Arrr! O' course, these parts are very curved with lots o' edges and corners, so t' fiberglassin' looked absolutely horrible with ragged loose threads, me bucko, folds, and fabric edges everywhere. Ahoy! Avast, me proud beauty! I set t' project aside again in frustration.

Then when t' warm weather o' sprin' came six weeks later, arrr, me hearties, I took it out, slowly sanded it down, inserted head weight again, ya bilge rat, me hearties, and made some real progress. This time, me bucko, I kept t' test glides very limited. Nothin' was broken during testing, but I didn't have much confidence in t' glide. Begad! Aye aye! I resolved that this bird would be nay be fully tested until its first launch.

Thus, I went ahead and painted t' glider. It took a lot o' white t' cover t' massive wingspan. Blimey! Ahoy! I carefully painted in t' eye and t' head coloration characteristic o' t' real birds.

Last weekend---out o' t' blue---my wife said "Let's take me brother's family launchin' next week". (Pretty good wife!) Well, I took this as a sign that I had t' finish t' Albatross.

I had been eyein' NCR's Oktoberfest as t' first launch o' t' Albatross, but I was reluctant t' embarrass myself with t' spectacular crash I believed was all but certain. Avast! Well, blow me down! T' launch it next weekend, arrr, I could destroy it with far fewer witnesses!

So, matey, I smartly finished t' boost pod. Ya scallywag! It was BT-70, 29mm, about 4 feet tall. Aye aye! Ya scallywag! I put t' glider bracket on one side. Begad! Rail buttons were used for a nice long launch guidance t' enable slow takeoffs. Begad! Ya scallywag! I was slightly worried about stability in t' axis parallel with t' win' because t' glider had very little surface area perpendicular t' the wings. Begad! So I decided t' add a fin shaped like a fish. Blimey! This made it look like t' albatross was carryin' t' fish in its claws. Ahoy! Aye aye! Aside from that, me bucko, arrr, me hearties, stability wasn't an issue at all because t' CG o' t' glider be so far forward (due t' the lead head) that I could make t' CG o' t' whole rocket anywhere I wanted by shiftin' t' vertical placement o' the mountin' bracket. Arrr! It is set 4.5" from t' tail o' t' tube, me hearties, and I added 0.5oz o' nose weight t' be sure.

T' fish was painted silver and t' rest o' t' pod was black. Blimey! I didn't even have time t' clear coat t' boost pod. Avast! In fact, I was so rushed t' make t' launch date that when I tried t' insert t' motor t' night before takeoff, I discovered that I had forgotten t' put an engine block in t' motor tube and me motor retention brackets didn't work because t' single-use motor I chose was shaped differently than me 29mm RMS casing. Begad! With a quick epoxy job and some bending, both problems were easily fixed.

Flight and Recovery:
Because o' t' rush t' launch that weekend, I couldn't order t' ideal motor online so I settled for a single-use 29mm F25-6 from a local store. Ya scallywag! Blimey! Bein' o' t' firm belief that t' Albatross would be good for only one flight, me bucko, I was determined nay t' miss t' takeoff photo. Arrr! Blimey! Well, ya bilge rat, I missed it anyway! Blimey! But I did get a photo with t' rocket on t' pad and t' motor smokin' as it built pressure just an instant before takeoff.

T' F25 be a nice choice in terms o' power. It yielded a fairly slow liftoff with modest altitude. Aye aye! T' glider separated perfectly, shiver me timbers, slightly before apogee. Aye aye! Avast, me proud beauty! As I had feared, matey, matey, t' 6-sec delay was way too long for t' boost pod. Blimey! Arrr! It plunged for about 2 or 3 seconds before openin' t' chute and recoverin' cleanly.

T' me utter amazement, t' glider soared easily through t' sky, settlin' in t' a series o' broad, me hearties, lazy circles about 700 feet high. Well, blow me down! Everybody started cheering. Avast, me proud beauty! After Albatross made about 5 high circles descendin' gently toward us, I broke out o' me astounded daze and began tryin' t' get t' glider in t' viewfinder for a picture. Avast! Avast! I just couldn't find it. Ahoy! As I be trying, t' cheers turned t' gasps. I didn't really see t' last part, but me wife and brother-in-law tell me that about 75 feet off t' ground, matey, shiver me timbers, t' Albatross turned into a steep spiral and then into a straight nose dive. They say that she hit a crosswind. Begad! Apparently t' glider had only limited roll stability. Aye aye! It got knocked too far sideways by t' crosswind and couldn't recover. It plunged t' last 50 feet and lawndarted in t' prairie, buryin' the whole head. Avast, me proud beauty!

Summary:
My feelings about this are funny. Avast, me proud beauty! I be utterly convinced that t' glider wouldn't fly, so I was emotionally prepared for total destruction. Blimey! Avast! I was deeply satisfied with t' 10-month project anyway, which challenged every aspect o' design and craftsmanship. Blimey! But when t' Albatross actually flew and circled up high, ya bilge rat, I be amazed and thrilled. Ahoy! What a fantastic feeling! Those brief moments changed me hopes, and when Albatross crashed I was completely heartbroken. Aye aye!

Where does this leave me? Perhaps I'll rebuild for another attempt. Aye aye! Begad! I'm too crushed today t' decide so I'll think about it for a while. If I don't rebuild, I have a new opportunity t' dream up and build some other excitin' giant glider project. Avast, me proud beauty! For me, t' pursuit o' somethin' new is usually t' most fun so perhaps t' Albatross will have t' be only a memory now. Arrr! We'll see.
