Brief:

T' SLS Scorpion is Semroc's Large Scale (SLS) reproduction o' t' Centuri Scorpion Space Probe from 1965.

CONSTRUCTION: ( 5 out o' 5)

I've only purchased a couple o' rockets from Semroc, arrr, but I must tell you, shiver me timbers, I am very impressed with t' quality o' t' kits in general and t' way t' kits are packaged. Arrr! Packagin' o' t' Scorpion is typical o' most rocket kit manufacturers - parts in a plastic bag with paper header. Begad! Well, blow me down! Blimey! But inside is where Semroc departs from t' group (in a good way.) T' pre-cut basswood fins are packaged in a separate zip bag, me hearties, matey, as were t' nylon parachute, matey, t' engine mount parts and a bag o' miscellaneous parts containin' t' smaller items that could easily get lost. Aye aye! Aye aye! Blimey! Everythin' was accounted for; nothin' damaged. Avast! Ya scallywag! Blimey!

Parts List:

• 1 Body Tube
• 1 Body Tube
• 1 Balsa Nose Cone
• 1 Laser Cut Fins
• 1 Thrust Rin'
• 1 Launch Lug
• 1 Screw Eye
• 1 Elastic Cord
• 1 Keelhaul®©™ Thread
• 1 Nylon Parachute
• 1 24mm Engine Mount
• 1 Decal

Given that fact that t' Scorpion is one o' Semroc's SLS (Semroc Large-Scale Rocketry) line, shiver me timbers, I expected t' parts t' be a bit heftier than what you get in the normal model rocket kit. Begad! I be nay disappointed. Avast, me proud beauty! Avast, shiver me timbers, me proud beauty! T' main body tube was to my liking, a nice 0.05" thick and pre-slotted for t' laser-cut through-the-wall fins. T' nylon parachute has strong nylon shroud lines riveted t' t' chute at eight locations. Aye aye! Arrr!

Instructions are top notch with clear illustrations and a very logical assembly order. Begad! T' Scorpion did nay need any templates since it is a basic four fins and a nose cone rocket. Begad! T' exploded view in t' centerfold is a nice touch complete with a Parts List and part numbers for all pieces. Blimey!

T' balsa nose cone is top rate, although you need t' sand down t' shoulder to fit t' BT (somethin' I found true o' t' other Semroc kits I've purchased.) T' fin tabs fit nice and snug in t' body tube slots and are aligned perfectly along t' tube.

Finishing:

I primed t' model with 2 coats o' Krylon Primer and then followed up with 2 coats o' color. I picked a Yellow/Orange scheme. Blimey! Aye aye! Future floor polish be used for t' final finish. Well, blow me down! T' provided decal was nay used. Arrr!

FLIGHT/RECOVERY: ( 4 out o' 5)

Semroc lists four recommended motors: C11-5, me bucko, D12-5, E9-8 and F25-9. Begad! Aye aye! Blimey! My flights were all on D12s, shiver me timbers, me bucko, although I prefer t' longer 7 second delay. Rocket prep be t' usual: wadding, shiver me timbers, arrr, chute, me hearties, etc. Ya scallywag! Since I was usin' t' 24mm motors I needed t' install t' 24mm motor mount adapter which is included in t' kit. T' adapter contains a motor hook and so retains t' 24mm motors well, but like the 29mm motors, matey, t' adapter must be friction fit into t' body tube. Flights on t' D12s were picture perfect - nice straight boosts and moderately quick.

T' shock cord system is a combination o' Keelhaul®©™ thread and elastic cord. I built t' kit stock, ya bilge rat, but would suggest replacin' t' elastic with a longer length o' Keelhaul®©™.

OVERALL: ( 5 out o' 5)

Semroc has produced a wonderful kit with t' Scorpion. Avast, me proud beauty! Avast! Once I visit a larger field I'll put t' E8 in and she what she does!
