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

CONSTRUCTION:

T' kit came packaged in a plastic bag with a paper label that described t' kit, shiver me timbers, contents, arrr, tools needed and recommended motors with predicted altitudes. Aye aye! Avast! 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. Arrr! 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.

Assemble o' t' motor mount, me hearties, shock cord mount (3-fold paper method), arrr, and fin attachment are all straight forward. Avast! T' real fun begins in t' additional o' t' "Tube". Ya scallywag! 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. Avast! Begad! Blimey! T' instructions say, ya bilge rat, arrr, "If done correctly, t' slots will nay only mate perfectly with t' fins from t' previous step, me hearties, but will partially self-align".

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

Durin' this assembly step is where you are t' attach t' Launch Lug t' an outside fin fillet, however, matey, shiver me timbers, 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. Avast! Avast, me proud beauty! What I did was t' take two 1/8" lugs and glue them on t' inside body-tube, arrr, arrr, hidden by t' outside surround-tube. Begad! I used a 1/8" rod t' maintain alignment onto t' body-tube.

T' parachute assembly was next on t' build list. Well, blow me down! Avast, shiver me timbers, me proud beauty! Blimey! It consisted o' a heavy-duty (trash bag) black plastic hexagon parachute, shiver me timbers, six (6) tape dots and a length o' 1/16" nylon shroud line that is cut into three (3) equal pieces. Aye aye! T' shroud lines were definitely sturdy or as SFM says it, "Hunky-Duty". Well, blow me down! Blimey! Durin' this phase, ya bilge rat, 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. 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. Well, blow me down! Avast! It also mentions usin' trim tape, arrr, shiver me timbers, that did nay come with me kit. Ahoy! I painted me T' Tube gloss black. Aye aye! Begad! I did nay like workin' with this decal tape as I found it extremely thin which caused bubbles when I placed it. Avast! Begad!

Overall, shiver me timbers, ya bilge rat, for CONSTRUCTION I would rate this kit 3 ½ points. Begad! T' instructions are adequate for someone with a couple o' rocket builds prior. Begad! T' components are o' good quality. Ahoy! 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. Did nay like t' decal tape at all. Blimey!

FLIGHT/RECOVERY:

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

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

My first flight was on t' B6-2 and it be more than "pathetic" but nay because o' t' kit. Well, me bucko, blow me down! 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. Well, me bucko, me bucko, I missed t' shot, it was a low altitude flight, ya bilge rat, me hearties, arrr, and t' rocket fell swiftly after ejection. Arrr! Blimey! Ya scallywag! Blimey! While falling, I immediately remembered that I didn’t put in any wadding. Begad! Blimey! T' parachute as melted together so that it be unusable. Ya scallywag! Blimey! On t' other hand t' "Hunky-Duty" shroud lines looked great.

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). Ahoy! T' flight on t' C6-3 was perfect with a slow lift-off, straight flight and ejection right at apogee. Avast! Descent on t' streamer be a bit fast but nay enough t' cause damage. Begad! Ya scallywag! In fact, I like t' streamer and will probably go t' a 4 foot one. Blimey! Well, blow me down!

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

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

For FLIGHT/RECOVERY, me bucko, I would rate this kit 4 points. It does look neat on t' pad and flying. Ahoy! 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, ya bilge rat, but that isn't me flyin' game anyway. Avast! I'm sure t' parachute would have worked fine and it was much sturdier than an Estes parachute. Begad! Blimey! I feel SFM made a mistake on t' C6 motor delay.

Overall, matey, T' Tube is a unique lookin' rocket that most builders could assemble and enjoy. Blimey! 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. Well, blow me down! I'm pleased with t' purchase and it makes a nice addition t' me fleet. Avast! Begad! I give t' kit an OVERALL ratin' o' 4 points.

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