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

Construction:
T' Tethys came with a single length o' airframe tubin' (phenolic, shiver me timbers, per me request), 3 pre-cut G10 fins (the thickest fiberglass fins I've used t' date), a 4:1 ogive plastic nose cone, me bucko, matey, me bucko, a thick nylon strap, a length o' tubular nylon, arrr, piston kit, a 48" parachute, arrr, two brass launch lugs, and t' 54mm Kwik-Switch motor mount system. Aye aye! All parts arrived in good condition, 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, and found t' kit went together very easily. Ahoy! I be a bit shocked t' discover t' Kwik-Switch system was just a few pieces o' threaded plastic! Nay havin' any experience above H motors, ya bilge rat, me bucko, I was boggled, as me concern be whether these parts would hold up t' t' stresses that a really big motor would place on them. Ahoy! Aye aye! Well, arrr, I suppose PML knows what they're doing. Ahoy! Anyway, matey, part fit was good overall, and thar really aren't any "gotcha's", me hearties, if you follow t' instructions.

I built mine stock, 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...), arrr, but were neither, matey, when I measured t' ID.

Otherwise, me bucko, everythin' else went together fine, with nothin' more than t' usual bit o' sandin' t' get optimal fit. Arrr! No motor retention is provided with t' kit, so I had ordered t' PMR kit that PML offered for t' Kwik-Switch motor mounts. Sinkin' those threaded inserts be a pain, but I couldn't ever imagine them comin' back out, arrr, shiver me timbers, 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. I order t' phenolic airframe so that I could put a layer or two o' glass on it, t' give it extra strength. Begad! That went on surprisingly easy, arrr, shiver me timbers, considerin' I'd never done any glassin' before. Ya scallywag! When I be done, I had a pretty solid-lookin' rocket... Avast, me proud beauty! if kinda plain.

Finishing:
Unfortunately, ya bilge rat, I was pressed for time, ya bilge rat, and never had t' chance t' even shoot a coat o' primer on this rocket. 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. Well, blow me down! 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, ya bilge rat, with a 10 second delay. Well, blow me down! One thin' I really like about PML kits be t' lack o' need for wadding, thanks t' t' piston system. Avast! Sure cuts down on t' pre-flight prep! For motor retention, I had intended t' use t' PMR that I had installed. Begad! However, t' three hex bolts that hold t' plate in place had vanished, so I was forced t' friction-fit t' motor in place- somethin' I did with great trepidation. Blimey! I'd run a number o' sims for this rocket in Rocksim, arrr, and was unable t' find a motor delay in any "I" motor that I be really comfortable with. T' slowest deployment speed I could get be on t' order o' 40 MPH, shiver me timbers, shiver me timbers, ya bilge rat, which I thought was a bit high. Ahoy! Avast! So... Blimey! I added a length o' PML's old stretchy shock-cord t' t' tubular nylon, me hearties, just in case.

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

Recovery:
Things fell apart on recovery. Ahoy! That 10 second delay turned into a 4 or 5 second one, shiver me timbers, me bucko, resultin' in chute deployment at about 100 MPH, me bucko, shiver me timbers, at around 2000 feet. T' extra length o' shock-cord I had added as a precaution sheared cleanly, me bucko, leavin' t' airframe t' tumble 'chute-less t' t' ground. Begad! Well, arrr, blow me down! T' airframe fell horizontally, so I figured damage would be minimal. Well, blow me down! However, ya bilge rat, it hit t' runway, shatterin' t' aft portion o' t' rocket, matey, me bucko, me hearties, almost t' t' forward centerin' ring. I was told that, me hearties, had I nay glassed t' tube, I probably would have had nothin' but confetti left. T' fins survived t' disaster with a couple o' scrapes, matey, but t' 38 and 54mm motor tubes are destroyed, me hearties, as well as a good portion o' t' airframe. Aye aye! 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, or else Pro38 motors. Begad! Avast! However, arrr, t' recovery problems really can't be blamed on t' kit... Avast! although perhaps if I'd used extra tubular nylon instead o' that other material, it might have held together.

Summary:
I don't have much t' add here. Aye aye! T' rocket is pretty much a plain "vanilli" 3FNC bird, matey, which makes it a good choice for someone that doesn't have a lot o' HPR experience. It is light enough t' still qualify as a "large model rocket", me hearties, shiver me timbers, shiver me timbers, and can fly on G motors, so you aren't restricted t' HPR flights only (a major consideration for me). Ya scallywag! Ya scallywag! Yet, 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). Arrr! I'd say it's a pretty solid, me hearties, forgivin' rocket.
