T' kit includes a 18" BT55 main body-tube, me hearties, a 14" BT80 surround-tube, arrr, arrr, three (3) ¼" balsa fins, me bucko, and a sharp-point plastic nose cone. It also comes with an 18mm motor mount with retention and 1/16" plywood centerin' rings. A 48" elastic shock cord and a 14" plastic parachute with "Hunky-Duty" shroud lines (1/16" nylon) make up t' recovery system. Well, blow me down! A 3/16" launch lug and some decal tape wrapped up t' kit. Begad!

CONSTRUCTION:

T' kit came packaged in a plastic bag with a paper label that described t' kit, contents, matey, tools needed and recommended motors with predicted altitudes. Avast! Begad! T' instructions added another 3 pages o' assembly information and templates and a 4th page o' general buildin' and flight preparation tips that can be applied t' any rocket. T' instructions included diagrams that help in assembly and each main step had t' necessary sub-steps t' allow for a smooth and logic build. Aye aye!

Assemble o' t' motor mount, shock cord mount (3-fold paper method), and fin attachment are all straight forward. T' real fun begins in t' additional o' t' "Tube". Aye aye! Here you are instructed t' use a markin' guide and t' mark t' BT80 tube and then cut t' slots that allow t' tube t' pass over t' fins. Aye aye! T' instructions say, "If done correctly, ya bilge rat, t' slots will nay only mate perfectly with t' fins from t' previous step, me hearties, ya bilge rat, but will partially self-align".

Once t' slots are cut in t' surround-tube, ya bilge rat, then this is slid over t' rocket and down onto t' slots, shiver me timbers, ya bilge rat, maintainin' equal distance from t' inner body-tube. Well, blow me down! Aye aye! A concentric alignment disk is provided, which is cut from page 3 o' t' instructions. Blimey! This is slide over t' top o' t' body-tube t' ensure t' surround-tube is equally spaced at t' end opposite o' t' fins. Arrr! Blimey! It would have been nice t' have t' concentric alignment disk a bit stiffer, shiver me timbers, like from cardstock, but t' paper one worked. Well, me bucko, blow me down! T' objective is t' then put a few "tack" drops o' glue on t' fins and surround-tube once aligned. Avast! Only a few drops so that if a mistake is made it could be cut-out and attempted again. Arrr! Ya scallywag! Once set, ya bilge rat, arrr, then fin fillets are applied.

Durin' this assembly step is where you are t' attach t' Launch Lug t' an outside fin fillet, me bucko, arrr, however, shiver me timbers, me hearties, I didn’t like t' idea o' me launch lug in showin' on t' outside and I must have lost t' 3/16" lug provided. Ahoy! Ya scallywag! What I did was t' take two 1/8" lugs and glue them on t' inside body-tube, matey, hidden by t' outside surround-tube. Begad! I used a 1/8" rod t' maintain alignment onto t' body-tube. Arrr!

T' parachute assembly was next on t' build list. Begad! Blimey! Begad! Blimey! It consisted o' a heavy-duty (trash bag) black plastic hexagon parachute, ya bilge rat, six (6) tape dots and a length o' 1/16" nylon shroud line that is cut into three (3) equal pieces. Arrr! Blimey! T' shroud lines were definitely sturdy or as SFM says it, "Hunky-Duty". Blimey! Blimey! Durin' this phase, t' instructions recommend purchasin' t' Klutz Book o' Knots t' gain descriptions o' t' Prusik knot (#14) and t' Harness Loop (#21) which would both be good knots for securin' t' shroud lines t' t' parachute. Arrr! Blimey! Ahoy! Blimey! T' instructions tell t' builder t' simply knot and glue at each tape junction.

T' instructions then describe a simple finishin' technique with flat black paint and suggest usin' t' orange and yellow decal tape provided. Aye aye! Arrr! It also mentions usin' trim tape, shiver me timbers, me bucko, matey, that did nay come with me kit. Well, blow me down! Ya scallywag! I painted me T' Tube gloss black. Arrr! I did nay like workin' with this decal tape as I found it extremely thin which caused bubbles when I placed it. Avast, me proud beauty!

Overall, for CONSTRUCTION I would rate this kit 3 ½ points. Aye aye! Avast, me proud beauty! T' instructions are adequate for someone with a couple o' rocket builds prior. Ya scallywag! T' components are o' good quality. Well, blow me down! I would like t' see a thicker concentric rin' and t' old 3-fold paper method should probably go t' a Keelhaul®©™ t' motor mount method. Well, blow me down! Did nay like t' decal tape at all. Begad!

FLIGHT/RECOVERY:

T' recommend (or not) motors that SFM outlines are as follows:

• B6-2 – 150 feet – Pathetic, shiver me timbers, nay recommend
• C6-5 – 400 feet – Pretty cool flights
• D13-4 – 700 feet – Excellent flights, matey, our favorite combo
• D21-4 – 700 feet – Excellent flights
• D24-4 – 700 feet – Rockin’ flights on blue flame! Blimey!

My first flight be on t' B6-2 and it be more than "pathetic" but nay because o' t' kit. Blimey! Blimey! Begad! Blimey! I was at me newly found flyin' field and be in a big hurry t' get a flight off and capture it on camera. Begad! Blimey! Aye aye! Blimey! Well, arrr, I missed t' shot, it be a low altitude flight, shiver me timbers, and t' rocket fell swiftly after ejection. Avast! Blimey! While falling, I immediately remembered that I didn’t put in any wadding. Begad! Blimey! T' parachute as melted together so that it was unusable. Avast, me proud beauty! Blimey! On t' other hand t' "Hunky-Duty" shroud lines looked great. Avast! Blimey! Begad! Blimey!

I had a 3" x 2’ streamer so I threw that on T' Tube (and used waddin' this time) and installed a C6-3 (note: above, I believe SFM’s recommendation o' a C6-5 should be a C6-3). T' flight on t' C6-3 was perfect with a slow lift-off, shiver me timbers, ya bilge rat, straight flight and ejection right at apogee. Descent on t' streamer was a bit fast but nay enough t' cause damage. Blimey! In fact, ya bilge rat, I like t' streamer and will probably go t' a 4 foot one. Ahoy!

T' third flight was on a later day and I used t' C6-3 again. Begad! Blimey! Another very nice flight, me hearties, although ejection be very near apogee but still nose cone up. Upon t' descent with t' streamer it seemed like t' air passin' through t' tube was tryin' t' make if fly around. Blimey! Blimey! It didn't fall straight it sorta flew left then turned and flew right and then etc all on a fairly rapid descent rate. Arrr! Blimey! I'm sure t' parachute would have prevented that, me bucko, but I like t' rate with t' streamer.

Usin' me idea o' hidin' t' Launch Lug on t' main body-tube verses on t' outside o' t' surround-tube worked fine and looks great. I’d recommend this change. Blimey! Well, blow me down! Blimey!

My next planned flight will be at NARAM on a D21-4 that I anticipate bein' a great flight. Begad! Watch me flight logs!

For FLIGHT/RECOVERY, arrr, shiver me timbers, I would rate this kit 4 points. It does look neat on t' pad and flying. Begad! Avast! It gives slow lift-offs on t' B6 and C6 t' allow some time t' enjoy lift off. Begad! It is nay a maximum altitude performer, me hearties, but that isn't me flyin' game anyway. I'm sure t' parachute would have worked fine and it was much sturdier than an Estes parachute. Arrr! Ahoy! I feel SFM made a mistake on t' C6 motor delay. Begad!

Overall, arrr, T' Tube is a unique lookin' rocket that most builders could assemble and enjoy. Aye aye! I would suggest hidin' t' launch lug like I did and by all means use waddin' (silly me)! It is a nice small field rocket usin' your Estes B6 and C6 motors which allows for a greater range o' fliers t' enjoy it. Begad! Aye aye! I'm pleased with t' purchase and it makes a nice addition t' me fleet. Begad! I give t' kit an OVERALL ratin' o' 4 points. Arrr!

Now, after writin' this review and enjoyin' t' kit, shiver me timbers, shiver me timbers, I've just discovered that Suborbital Flyin' Machines is no longer in business! Bummer, matey, I guess thar won't be any T' Tube II's. Ahoy! If you hurry, matey, Kevin at Discount Rocketry says he still has a few.
