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, per me request), 3 pre-cut G10 fins (the thickest fiberglass fins I've used t' date), me hearties, me hearties, a 4:1 ogive plastic nose cone, arrr, me bucko, a thick nylon strap, me hearties, me hearties, a length o' tubular nylon, piston kit, ya bilge rat, a 48" parachute, two brass launch lugs, and t' 54mm Kwik-Switch motor mount system. Avast, me proud beauty! 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, shiver me timbers, and found t' kit went together very easily. Blimey! Well, matey, blow me down! 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, me bucko, I be boggled, me bucko, as me concern be whether these parts would hold up t' t' stresses that a really big motor would place on them. Well, I suppose PML knows what they're doing. Begad! Anyway, me bucko, matey, part fit be good overall, me bucko, shiver me timbers, matey, and thar really aren't any "gotcha's", me hearties, if you follow t' instructions.

I built mine stock, ya bilge rat, with one exception- I replaced t' lugs with 1/4" ones. Begad! Ya scallywag! 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, me bucko, but were neither, shiver me timbers, arrr, when I measured t' ID.

Otherwise, everythin' else went together fine, with nothin' more than t' usual bit o' sandin' t' get optimal fit. No motor retention is provided with t' kit, me hearties, so I had ordered t' PMR kit that PML offered for t' Kwik-Switch motor mounts. Ya scallywag! 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), shiver me timbers, 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. That went on surprisingly easy, considerin' I'd never done any glassin' before. Avast! Avast, me proud beauty! When I be done, I had a pretty solid-lookin' rocket... Avast, me proud beauty! if kinda plain.

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

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

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

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

Summary:
I don't have much t' add here. T' rocket is pretty much a plain "vanilli" 3FNC bird, 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", arrr, and can fly on G motors, me bucko, so you aren't restricted t' HPR flights only (a major consideration for me). Blimey! Well, blow me down! 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). Avast! Ahoy! I'd say it's a pretty solid, forgivin' rocket.
