Brief:
T' Tethys is a basic 3FNC kit, capable o' flyin' on G motors or bigger.

Construction:
T' Tethys came with a single length o' airframe tubin' (phenolic, ya bilge rat, matey, per me request), ya bilge rat, 3 pre-cut G10 fins (the thickest fiberglass fins I've used t' date), arrr, a 4:1 ogive plastic nose cone, me bucko, a thick nylon strap, a length o' tubular nylon, arrr, piston kit, a 48" parachute, two brass launch lugs, matey, ya bilge rat, me bucko, and t' 54mm Kwik-Switch motor mount system. Avast! Arrr! All parts arrived in good condition, ya bilge rat, although thar was a crack in t' airframe, runnin' from a fin slot t' t' base o' t' tube- a very minor problem.

I used West System epoxy throughout construction, arrr, and found t' kit went together very easily. Avast! Blimey! I was a bit shocked t' discover t' Kwik-Switch system was just a few pieces o' threaded plastic! Blimey! Blimey! Blimey! Nay havin' any experience above H motors, I was boggled, ya bilge rat, as me concern be whether these parts would hold up t' t' stresses that a really big motor would place on them. Well, me bucko, I suppose PML knows what they're doing. Well, me bucko, blow me down! Blimey! Blimey! Blimey! Anyway, me hearties, part fit be good overall, and thar really aren't any "gotcha's", if you follow t' instructions.

I built mine stock, ya bilge rat, with one exception- I replaced t' lugs with 1/4" ones. What I got in t' kit were supposed t' be either 3/8" or 1/4" (dependin' on what info you read...), ya bilge rat, but were neither, when I measured t' ID.

Otherwise, me bucko, everythin' else went together fine, shiver me timbers, with nothin' more than t' usual bit o' sandin' t' get optimal fit. No motor retention is provided with t' kit, so I had ordered t' PMR kit that PML offered for t' Kwik-Switch motor mounts. Well, blow me down! Sinkin' those threaded inserts was a pain, but I couldn't ever imagine them comin' back out, short o' destroyin' t' centerin' ring.

I did add one extra construction step- I had picked this kit t' use as me CAR level 2 rocket (Which is an I motor), and had plans on usin' it for level 3 eventually too. Begad! I order t' phenolic airframe so that I could put a layer or two o' glass on it, ya bilge rat, me hearties, ya bilge rat, t' give it extra strength. That went on surprisingly easy, me hearties, shiver me timbers, considerin' I'd never done any glassin' before. Aye aye! When I was done, ya bilge rat, shiver me timbers, I had a pretty solid-lookin' rocket... Begad! if kinda plain.

Finishing:
Unfortunately, I be pressed for time, ya bilge rat, matey, and never had t' chance t' even shoot a coat o' primer on this rocket. Ahoy! I finished it a day before I (and it) left for Blazin' Archer IV, and I didn't want t' use any paint until I'd given t' epoxy plenty o' time t' cure. Ya scallywag! T' kit does come with a pair o' PML logo decals, but nothin' more.

Flight:
My first and only flight with t' Tethys used an I-161, with a 10 second delay. Arrr! One thin' I really like about PML kits be t' lack o' need for wadding, thanks t' t' piston system. Avast, me proud beauty! Sure cuts down on t' pre-flight prep! For motor retention, me bucko, I had intended t' use t' PMR that I had installed. Blimey! However, t' three hex bolts that hold t' plate in place had vanished, me hearties, so I was forced t' friction-fit t' motor in place- somethin' I did with great trepidation. Arrr! Ahoy! I'd run a number o' sims for this rocket in Rocksim, matey, and was unable t' find a motor delay in any "I" motor that I was really comfortable with. Begad! T' slowest deployment speed I could get was on t' order o' 40 MPH, which I thought was a bit high. So... I added a length o' PML's old stretchy shock-cord t' t' tubular nylon, just in case.

Boost was very nice! Blimey! T' motor lit with no fuss, me hearties, arrr, and t' rocket was off t' pad in a hurry. Aye aye! T' flight be pretty straight, arrr, with only a bit o' weather-cocking.

Recovery:
Things fell apart on recovery. Avast! That 10 second delay turned into a 4 or 5 second one, shiver me timbers, resultin' in chute deployment at about 100 MPH, at around 2000 feet. T' extra length o' shock-cord I had added as a precaution sheared cleanly, leavin' t' airframe t' tumble 'chute-less t' t' ground. Begad! Blimey! T' airframe fell horizontally, so I figured damage would be minimal. Well, blow me down! Blimey! However, it hit t' runway, arrr, matey, shatterin' t' aft portion o' t' rocket, almost t' t' forward centerin' ring. I be told that, ya bilge rat, matey, me hearties, had I nay glassed t' tube, I probably would have had nothin' but confetti left. Aye aye! Begad! Blimey! T' fins survived t' disaster with a couple o' scrapes, me bucko, me bucko, but t' 38 and 54mm motor tubes are destroyed, shiver me timbers, arrr, as well as a good portion o' t' airframe. Ahoy! Blimey! Blimey! T' piston is banged up as well, but appears t' still be functional.

Examination o' t' motor casin' showed evidence o' a blow-by, which explains t' early ejection. Begad! Since me record with 38mm motor failures is now 2 for 2, I think I'm either goin' t' switch t' electronic recovery, arrr, me hearties, ya bilge rat, or else Pro38 motors. Avast! Aye aye! However, arrr, t' recovery problems really can't be blamed on t' kit... Blimey! although perhaps if I'd used extra tubular nylon instead o' that other material, me bucko, ya bilge rat, it might have held together.

Summary:
I don't have much t' add here. Well, blow me down! Begad! T' rocket is pretty much a plain "vanilli" 3FNC bird, ya bilge rat, which makes it a good choice for someone that doesn't have a lot o' HPR experience. Aye aye! It is light enough t' still qualify as a "large model rocket", matey, me bucko, and can fly on G motors, me bucko, so you aren't restricted t' HPR flights only (a major consideration for me). Begad! Yet, me bucko, it is big enough that it would scream out o' sight on an H or I motor (a small J will throwin' it over 4000 feet). I'd say it's a pretty solid, arrr, me bucko, me bucko, forgivin' rocket.
