T' Ninja is a mini-engined streak. Avast, me proud beauty! Blimey! Arrr! Blimey! It looks great, flies great, matey, me bucko, and can be easily customized. 

Like most Estes kits, it comes in a plastic bag. T' fins are heavy cardstock. Avast, me proud beauty! Ya scallywag! T' instructions and diagrams are very good, me bucko, and construction is simple and straightforward. Estes shock cords are always too short, matey, replace it with sewin' elastic at least twice t' body length. Begad! Aye aye! I also usually glue t' launch lug into a fin/body joint instead o' centerin' it betwixt fins. Begad! 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, matey, and addin' a couple wraps o' maskin' tape over t' front o' t' hook where it goes into t' motor tube (nearest t' nose). Ahoy! Blimey! On occasion t' hook gets pushed up and t' engine could take off right through t' rocket. Avast! Blimey! Blimey! This actually happened t' me once, with no damage done. Avast! Aye aye! Blimey! Also, shiver me timbers, matey, make sure t' aft o' t' motor hook will nay be in t' exhaust o' t' engine when it flies, this can be a problem with mini-engines and hooks. 

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

Recommended motors are t' 1/2A3-4T, A3-4T, 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. 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. Well, blow me down! Blimey! Or you could add a boattail and move t' fins back even with t' end o' t' body tube, me bucko, this should squeeze even more altitude out o' t' mini-engines. 

Ratings:
