T' kit includes a 18" BT55 main body-tube, shiver me timbers, a 14" BT80 surround-tube, me hearties, shiver me timbers, three (3) ¼" balsa fins, and a sharp-point plastic nose cone. Arrr! 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. Ya scallywag! Avast! A 3/16" launch lug and some decal tape wrapped up t' kit. Aye aye!

CONSTRUCTION:

T' kit came packaged in a plastic bag with a paper label that described t' kit, ya bilge rat, matey, contents, arrr, tools needed and recommended motors with predicted altitudes. 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. Begad!

Assemble o' t' motor mount, shiver me timbers, shock cord mount (3-fold paper method), and fin attachment are all straight forward. Avast, arrr, me proud beauty! Blimey! T' real fun begins in t' additional o' t' "Tube". Avast! Blimey! 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. T' instructions say, "If done correctly, arrr, me bucko, 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, matey, ya bilge rat, then this is slid over t' rocket and down onto t' slots, me hearties, maintainin' equal distance from t' inner body-tube. Avast! Begad! A concentric alignment disk is provided, which is cut from page 3 o' t' instructions. 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. It would have been nice t' have t' concentric alignment disk a bit stiffer, arrr, arrr, like from cardstock, ya bilge rat, 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. Blimey! Blimey! Only a few drops so that if a mistake is made it could be cut-out and attempted again. Once set, then fin fillets are applied.

Durin' this assembly step is where you are t' attach t' Launch Lug t' an outside fin fillet, ya bilge rat, however, ya bilge rat, 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. Blimey! Avast! What I did was t' take two 1/8" lugs and glue them on t' inside body-tube, hidden by t' outside surround-tube. I used a 1/8" rod t' maintain alignment onto t' body-tube. Ya scallywag!

T' parachute assembly be next on t' build list. Ahoy! It consisted o' a heavy-duty (trash bag) black plastic hexagon parachute, six (6) tape dots and a length o' 1/16" nylon shroud line that is cut into three (3) equal pieces. Begad! Well, blow me down! T' shroud lines were definitely sturdy or as SFM says it, "Hunky-Duty". Ahoy! Durin' this phase, shiver me timbers, 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. Begad!

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

Overall, me hearties, for CONSTRUCTION I would rate this kit 3 ½ points. Begad! T' instructions are adequate for someone with a couple o' rocket builds prior. Ya scallywag! T' components are o' good quality. Blimey! 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. Aye aye! Did nay like t' decal tape at all. Ahoy! Well, blow me down!

FLIGHT/RECOVERY:

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

• B6-2 – 150 feet – Pathetic, nay recommend
• C6-5 – 400 feet – Pretty cool flights
• D13-4 – 700 feet – Excellent flights, shiver me timbers, 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 was more than "pathetic" but nay because o' t' kit. Ahoy! I was at me newly found flyin' field and was in a big hurry t' get a flight off and capture it on camera. Arrr! Begad! Blimey! Well, matey, I missed t' shot, shiver me timbers, it was a low altitude flight, and t' rocket fell swiftly after ejection. Begad! While falling, me hearties, I immediately remembered that I didn’t put in any wadding. Avast! T' parachute as melted together so that it was unusable. On t' other hand t' "Hunky-Duty" shroud lines looked great. Avast, me proud beauty! 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). Aye aye! T' flight on t' C6-3 was perfect with a slow lift-off, matey, straight flight and ejection right at apogee. Descent on t' streamer was a bit fast but nay enough t' cause damage. Ahoy! In fact, I like t' streamer and will probably go t' a 4 foot one.

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

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

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

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

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