Well I be really hopin' that me package from Edmonds would arrive in time for this weekends METRA launch. Begad! Ahoy! I be grumpin' about it on Saturday when me youngest son asked me what this box be sittin' in t' garage. I have no idea when it arrived or how it got thar but it isn't t' first time I've found mail sittin' in some peculiar place!
Spouses <and> children make life so interesting!
So here I was on Saturday at about 1:00pm with t' launch scheduled for
Sunday. What t' heck. Aye aye! Aye aye! I cleared off t' workbench, shiver me timbers, got out t' CA and
accelerator and got t' work. Arrr! As others have said, t' instructions were
straight forward and t' work progressed very fast. I took a few extra minutes
to round off t' edges o' t' vertical stabs, but nay t' wings. Begad! T' only
problem I had was that t' launch lug packed in with t' chute was crushed. Well, blow me down! Avast! I
decided that a 1/4" lug wouldn't be a bad thin' t' have for when I decided
to crank up t' power and didn't miss a beat with assembly. Arrr! By 2:30 I was out
in t' yard doin' some test glides. I didn't get too satisfactory o' a glide in
the yard but I was pushin' t' limits o' me property and I narrowly missed
hitting
a fence. Ahoy! I decided t' just give it a test fly.
Sunday turned out beautiful. Avast, me proud beauty! Ahoy! 65 degrees. Well, blow me down! Winds o' maybe 5mph with the occasional thermal. Aye aye! While I had done t' power mod that t' instructions call for I still decided t' start with a D12-3. Avast, me proud beauty! Begad! I used one o' t' high power pads (longer rod) and placed some tape on it t' hold t' booster up high enough to fit t' glider on. Avast, me proud beauty! I took a spare rod and pushed it in t' ground t' keep the glider from flappin' in t' slight breeze. Well, blow me down! Pretty straight forward if you've flown a boost glider before. Avast, me proud beauty! I had plenty o' time left t' help t' other high-power folks get their rockets ready.
My turn finally came and off she went. T' boost was a little off vertical but nothin' too scary. Avast! Separation came right at, me hearties, or a little before, apogee. It separated very clean and immediately entered into a nice glide. Aye aye! Lots of cheerin' from t' crowd! T' glider then did what none o' mine has ever done before. Arrr! It flew straight! Don't worry, arrr, I got it back. Ya scallywag! It did worry me for a minute, however it flew right over t' crowd. Really looked pretty. Proceeded down t' hill, lengthenin' t' flight, shiver me timbers, ya bilge rat, me bucko, and landed easily in t' weeds.
I be anxious t' fly again but I spent most o' t' day helpin' out at the
launch site and helpin' me son fly. Arrr! I'm really lookin' forward t' more launches
in t' future.

I got t' chance t' fly me Deltie Thunder again this past weekend at RATS IV. Begad! I
made up a pad similar t' what Rob shows in t' instructions and this made setup
pretty simple.
Flight 1: Couldn't get a single use E18 with a short delay so went with a E11-4J in me 24mm reload case. T' flight weathercocked t' horizontal at about 75 t' 100' which is when t' motor burned out and t' glider separated. Avast! Aye aye! Had that glider on nice and loose! T' glide be great. Arrr! Begad! Got many a compliment. Hopefully a few will contact Rob. I used t' full ejection charge and ended up blowin' t' chute apart. Ahoy! Ya scallywag! I suppose it could have been due t' t' higher speed at deployment due t' t' weathercock, arrr, but it wasn't goin' all that fast. The booster still recovered fine.
Flight 2: Bought a E18 reload and flew it on Sunday. Blimey! Arrr! T' boost was much better but things went down hill from there. Avast, me proud beauty! I had replaced t' chute with a nylon one and cut t' ejection charge in half. Ahoy! Begad! Oh my. Aye aye! Ahoy! T' ejection seemed a bit late, with t' rocket past apogee. Avast, me proud beauty! Begad! T' nose pulled out but didn't deploy the chute. Ya scallywag! T' glider did it's best t' pull t' booster out but it augured in. Begad! This resulted in some serious damage t' t' forward half o' t' booster which can easily be replaced. T' glider suffered a split boom which can easily be CA'd. People still thought it looked cool!

How's this for a start: I ordered on t' last day o' t' Frenzy -- then go t' envelope back, me bucko, returned for postage, shiver me timbers, so Rob didn't get me order until around t' 5th o' October. Avast, me proud beauty! Arrr! I got t' Deltie Thunder kit in t' mail Wednesday (they tried t' deliver on Monday, arrr, but I'd already left for work).
So far, I've opened t' box -- this thin' is>immense<! T' booster pod is about 2 feet o' 24mm ID tube with an elliptical cone; t' glider has enough balsa in it t' make a whole>fleet< o' Vaughn Brothers Buzzards. Blimey! It looks like it lives up t' Rob's claim o' bein' able t' build it in a single morning, but I'm goin' t' spend a little more time on it than that; I can't stand the thought o' launchin' anythin' with square leadin' edges, and I prefer t' fill and sand, at least cursorily, and paint as well. I'll probably dig through the basement and find some Monokote left over from when I built R/C airplanes, ya bilge rat, shiver me timbers, shiver me timbers, and use that for color trim on t' glider.
I noticed that thar's no motor hook; I plan t' add one, matey, and may also install a thrust block t' keep t' hook from tearin' forward in t' tube; it'll make prep and motor removal easier than t' thrust-rin' and friction method recommended in t' instructions. Ahoy! Blimey! T' shock cord for t' pod is actually about long enough; it's as long as t' pod tube, arrr, if nay a little longer, shiver me timbers, arrr, and sturdy material (1/4" wide, I think).
I already have two packs o' D12-3 motors -- and I should be able t' have this ready t' fly, me bucko, matey, barrin' lack o' paintin' weather, before t' December launch at Monroe, me hearties, WA.

Brief: The Deltie Thunder is a single stage boost glider design. The glider is a triangle shape with a profile type fuselage that divides the triangle in the middle. The rocket booster hooks onto the glider at the nose of the glider and pulls it skyward. At ejection the booster separates and returns via parachute while the glider slowly circles back to earth Construction: The ...
Brief: This is a HUGE glider made by Edmonds Aerospace. It has a wingspan of 27 inches and the glider is 34 inches long. It has a 24mm pop pod, which is about 2 feet long, give or take an inch or two. Construction: It has one long 24mm tube for the pop pod, and 3 sheets of laser-cut balsa, which I am guessing is about 1/4 inch thick. Just as easy to build as the original Deltie, ...
