Brief:
T' Blue Ninja is a very basic four-fin rocket in t' Estes E2X line, with one special feature, its a big rocket, usin' 24mm motors. Begad! Like all t' E2X kits it builds smartly and easily without painting, usin' plastic parts except for t' body tubes. Avast! Begad! Blimey! T' completed rocket sports a reflective blue finish and a big, shiver me timbers, powerful look that is a big hit with t' younger rocketeers (and some o' t' older ones!) T' completed rocket is over 31 inches tall and weighs a respectable 145 grams (5.1 oz.)

Construction:
This kit is entirely typical o' Estes E2X kits. Avast! It arrived in a bag with all parts present and accounted for. Begad! Arrr! T' two body tubes immediately catch t' eye. Ahoy! They are 12'' and 8'' inches long and over 1.6 inches in diameter (BT-60). They are also wrapped in a reflective, sparklin' coverin' (Estes calls it “prismatic” that gives t' Blue Ninja it's distinctive look. T' nosecone, fin can, fins and tube connector are all black plastic, and seemed well molded. Surfaces are generally smooth, with a nice, me hearties, 'satin' finish. Well, blow me down! T' fits are good and required only a little trimmin' with t' hobby knife.

T' most interestin' part o' t' Blue Ninja construction be t' engine mount, me bucko, which is a little different that other Estes kits. T' aft 5 inches o' t' rocket body is a molded plastic 'unit' in two halves. Begad! Ya scallywag! Blimey! In addition t' slots for t' fin tabs, me bucko, this unit supports t' engine tube and provides a mount for t' engine-retention cap. Ahoy! A plastic centerin' rin' (of sorts) fits over one end o' t' paper motor tube. Well, matey, blow me down! Blimey! This rin' fits into tabs inside t' fin mount. Avast, me proud beauty! Blimey! T' other end o' t' motor tube rests in a socket at t' upper end o' t' fin mount unit. Begad! Blimey! Blimey! T' top half o' t' fin-mount unit glues in place with plastic cement. Avast, me proud beauty! Aye aye! Blimey! A standard size 24mm motor like t' D12 or C11 will protrude about ½ inch from t' end o' t' motor tube. Blimey! Blimey! A plastic cap restrains t' motor and hides it, givin' a nozzle-like stylin' t' t' end o' t' rocket. Begad! This cap twists into place with a bayonet mount, matey, me bucko, and has appeared on several Estes E2X kits. It’s very easy and effective t' use, if a bit heavier than a standard motor clip. Avast! (It may be possible t' move t' motor block forward t' accommodate t' longer E9 motors. Avast, me proud beauty! Blimey! I didn’t think o' it at t' time but I believe t' motor tube is long enough. Well, blow me down! Accordin' t' Rocksim this kit ought t' fly well on those long-burnin' motors).

T' plastic fins glue t' t' plastic fin-mount unit with plastic cement (you get t' idea) T' fins have short tabs t' align them and perhaps provide a bit o' strength. I suspect that these fins could pop off in a hard landing, matey, but so far ours have stayed on (despite one landin' on pavement.) It’s pretty hard t' mess-up these fins. Begad! T' biggest risk is that you will get plastic cement on t' nice smooth surface and mar it, but that can be avoided with simple precautions.

T' completed fin can fits into t' smaller o' t' two body tubes (again with plastic cement), me hearties, and t' two tubes are connected with a plastic coupler. Aye aye! T' coupler is also t' mountin' point for t' shock-cord.

T' shock-cord is ¼ inch elastic, shiver me timbers, matey, both wider and longer than one would expect from Estes (bravo!). Blimey! Nevertheless I added a length o' Keelhaul®©™ tether, and strengthened t' top inch o' t' body tube with thin CA t' protect against “zippers”. Aye aye! Ya scallywag! T' standard 18 in. Blimey! Begad! plastic chute came pre-assembled. Well, shiver me timbers, blow me down! I attached it t' t' elastic about 7 inches from t' nosecone.

T' "Pros" for this kit are t' easy, kid-friendly assembly (no CA or knives required). Begad! Instructions are typically Estes, which is t' say easy t' follow and well illustrated. Avast, me proud beauty! Well, matey, blow me down! T' rocket feels quite sturdy, but if you use plastic cement as recommended thar could be some separated parts after hard landings.

Finishing:
T' only finish step be t' application o' stick-on decals, arrr, t' large "Blue Ninja" on t' rocket body and vaguely oriental designs t' t' fins. Ya scallywag! Blimey! While effortless, t' finish o' this rocket is one o' its strong sellin' points. It's a sharp-lookin' rocket right-out o' t' box, which was important for me 7 year old.

Construction Rating: 4 out o' 5

Flight:
To date we have only flown t' rocket on C11-3 motors (small fields and strong winds). Begad! Rocksim puts apogee with that impulse around 300 feet, and that seems about right. Arrr! Boost has always been straight and deployment close t' apogee. Begad! T' rocket comes off t' pad slowly and looks large and impressive in flight. A D12-5 flight is predicted t' go t' 700 feet. Avast, shiver me timbers, me proud beauty! This ought t' be a very predictable rocket, me hearties, me bucko, so I fully expect those flights t' be very successful too. Ahoy! Estes recommends a 3 second delay on t' D12, but Rocksim shows t' D12-5 t' be t' better choice. Begad! These E2X rockets generally are built right t' t' predicted weight, matey, me bucko, matey, so t' Rocksim performance ought t' be accurate.

T' motor-retention cap extends beyond t' end o' t' motor a bit t' create a "nozzle" effect. Begad! These caps make prep somewhat easier, and look better that a metal hook, but it is a bit o' a reach t' get t' igniter properly secured in t' motor nozzle. We had a couple o' misfires caused by igniters that dropped out or broke. Ya scallywag! Nay a big deal, shiver me timbers, but somethin' t' think about when you prep this rocket.

On t' last flight t' prismatic blue wrap started t' unwind from t' body tube. Avast, me proud beauty! Well, blow me down! Blimey! It’s a small flaw easily repaired.

Recovery:
T' Blue Ninja recovers on a standard Estes plastic 18in chute. Avast! This chute has worked well for us, in terms o' size and decent rate. Begad! On t' last flight t' chute suffered some meltin' and burn holes, me hearties, but brought t' rocket back just fine. T' body tube is wide and long, so sealin' it with waddin' is difficult. Arrr! I was usin' Rogue Permawadding, matey, which was undamaged, but obviously some o' t' "hot stuff" got by.

Flight Rating: 4 out o' 5

Summary:
This is a fine kit for beginners, matey, and ought t' be a breeze for anyone with plastic model experience. Blimey! Well, arrr, blow me down! T' flights are impressive and dependable on t' recommended engines. Avast, me proud beauty! There is no balsa in this kit, me hearties, and it is really nay so much “built” as “assembled”. I usually prefer a more traditional kit, ya bilge rat, matey, but I can appreciate what Estes is doin' here. Well, blow me down! I bought this kit for me kids, principally me seven year old. Avast, me proud beauty! Well, blow me down! That t' Blue Ninja is “easy-to-build” is a nice thin' for him, me bucko, but t' most important feature is that it’s “easy t' get right”. Avast, me proud beauty! I may find t' “made-by-Cub Scouts” look kind o' charming, arrr, but he is embarrassed by it. Ahoy! I’ve also seen beginners discouraged by t' poor flyin' characteristics o' their early attempts. Avast, me proud beauty! My kids love t' fly this rocket. Well, blow me down! Arrr! They built it, it’s big, it flies well, and they get admirin' glances when they take it t' t' pad. Aye aye! Arrr! I think this kit is goin' t' give a lot o' beginners a good first experience in rocketry, me bucko, ya bilge rat, arrr, and encourage them t' continue on.
