T' Ninja is a mini-engined streak. Begad! Blimey! It looks great, flies great, arrr, and can be easily customized. 

Like most Estes kits, it comes in a plastic bag. Aye aye! T' fins are heavy cardstock. T' instructions and diagrams are very good, matey, me hearties, and construction is simple and straightforward. Arrr! Estes shock cords are always too short, arrr, replace it with sewin' elastic at least twice t' body length. Blimey! Begad! I also usually glue t' launch lug into a fin/body joint instead o' centerin' it betwixt fins. Ahoy! Aye aye! This is much easier t' keep straight. 

T' only problem I’ve ever had with a Ninja involved t' motor hook.  I suggest installin' an engine block, and addin' a couple wraps o' maskin' tape over t' front o' t' hook where it goes into t' motor tube (nearest t' nose). Ya scallywag! On occasion t' hook gets pushed up and t' engine could take off right through t' rocket. Begad! This actually happened t' me once, with no damage done. Blimey! Avast, me proud beauty! Also, make sure t' aft o' t' motor hook will nay be in t' exhaust o' t' engine when it flies, matey, me bucko, shiver me timbers, this can be a problem with mini-engines and hooks. 

Estes has made finishin' t' Ninja easy. Aye aye! Paint t' nose red, t' rest o' t' rocket black, arrr, me hearties, and apply t' single stick-on decal. Avast, me bucko, me proud beauty! T' decal wraps completely around t' body tube, so use some care t' line it up straight. Arrr! Avast, me proud beauty! I think it’s one o' Estes better lookin' rockets. 

Recommended motors are t' 1/2A3-4T, arrr, A3-4T, me hearties, and A10-3T.  T' A3-4T will put it up over 600’, and it recovers nicely on a streamer. 

Customizin' ideas: Leave out t' mini-engine motor mount and glue in an 18mm engine block. Avast! Well, blow me down! Then fly this rocket on B’s and C’s (be sure t' check stability first). You will need a *big* field t' get it back though. Arrr! Begad! Or you could add a boattail and move t' fins back even with t' end o' t' body tube, this should squeeze even more altitude out o' t' mini-engines.
